HERON 8896230 Inverter Generator

HERON 8896230 Inverter Generator PRODUCT

Introduction

Description – purpose of use of the generator

The inverter generator HERON® 8896230 is intended for powering electrical appliances in locations, where there is no access to the electrical power grid.
Thanks to the high quality of the input voltage (“smoothing out“ of the voltage waveform by the inverter system) and high operating electrical power output (3.5 kW) this generator is an energy source for a wide range of applications, that can be used no only for powering sensitive electrical appliances, e.g. computers and other office equipment, TVs, medical devices, etc., but also for powering power tools for work at construction sites, mobile service centres (if sensitive electrical appliances are not connected at the same time) or for recreational purposes for use at weekend cottages, in caravans, on boats, etc.
The inverter generator can also be used as a backup power source for photovoltaic island systems, where under unfavourable weather conditions the island system requires a backup electrical power source for short term recharging of batteries. Using non-inverter generators with AVR output voltage regulation is insufficient for charging the batteries of photovoltaic island systems since the control electronics of the photovoltaic system do not permit charging with low quality voltage.
The generator is equipped with a digital counter of total operational hours from the first start, operational hours from the previous start, current voltage and frequency, with the values shown on the display.
The generator is equipped with an output socket 12 V/8.3 A DC for charging car batteries.
Thanks to the new technical design of the exhaust pipe and the build of the generator, it has a reduced noise level.

ADDITIONAL INFORMATION FOR

The specified nominal voltage may exhibit values in the range of the permitted deviation for the power distribution grid.
The (nominal) operating power output (COP) is the total power output that the generator is able to pro-vide continuously, whilst providing a constant electrical load under operating conditions and use of the generator as specified by the manufacturer (including adherence to the maintenance plan and procedures). The specified max. power output serves for very short coverage of a higher current draw by a connected electrical device above the value of the continuous (long-term) operating power output, e.g. during the ramp up of an electric motor. Thus, the generator can only be continuously loaded at the value of the operating (nominal) power output. The total power output of the generator is understood to mean the total drawn power input of all the electrical appliances connected to the generator at a 230 V power voltage.
The circuit breaker is not triggered when the genera-tor reaches its max. power output. The circuit breaker is triggered when the generator is put under a load exceeding its max. electrical power output (when put under a load of approx. 4.2 kW). When the generator is put under a load exceeding the max. power output, the voltage drops significantly with its value shown on the counter and at a higher load the message “Error” may appear on the counter.
Power performance class G4: Voltage quality for powering sensitive electrical appliances, e.g. TVs, computers, medical devices.
Quality class A: At a different operating temperature or pressure than corresponding to the standard comparative conditions (see table 1), the nominal power output is not less than 95% of the initial value specified during standard comparative conditions (calculation according to ISO 3046-1).
The inverter system perfectly smooths out the sinusoid (alternating voltage waveform).
Standard comparative conditions: The ambient conditions of the environment for the specified nominal para-meters of the generator (nominal power output COP, fuel consumption, quality class).

Preparing the generator for operation

WARNING

Carefully read the entire user’s manual before first using the generator, and keep the manual with the product so that the user can become acquainted with it. If you lend or sell the generator to somebody, include this user’s manual with it. Prevent this user’s manual from being damaged. The manufacturer takes no responsibility for damages or injuries arising from use of the generator that is in contradiction with this user’s manual. Before using the generator, first acquaint yourself with all the control elements and parts as well as how to turn it off immediately in the event of a dangerous situation arising. Before using, first check that all parts are firmly attached and check that no part of the generator, such as for example safety protective elements, is damaged or incorrectly installed, or missing. Do not use a genera-tor with damaged or missing parts and have it repaired or replaced at an authorised service centre for the HERON® brand.

After unpacking, check the condition of the surface, working order of the control elements of the generator and whether there are any visible defects, e.g. unconnected cables, unconnected fuel supply hoses, etc.
Place the generator on a rigid, level surface in a well-ventilated location, which is at a safe distance from flammable and explosive mate-rials, and in locations without a flammable and explosive atmosphere.
Note
The generator set stands on rubber pads that dampen the vibrations of the generator during its operation and thereby reduce the emitted noise level and pre-vent the generator from moving along hard ground during operation.
WARNINGS
- The generator must not be operated in enclosed or poorly ventilated areas or in environments (e.g. in rooms, deeper outdoor trenches, etc.) since the exhaust fumes are toxic and may lead to poisoning of people or animals.
- The generator must not be operated in an environment that is flammable or has an explosive atmosphere.
- The generator must not be operated at an incline of more than 10° relative to the horizontal plane, since at a greater incline the lubrication system is insufficient and this leads to serious damage to the engine.
- If this incline of the generator is exceeded, fuel may leak out of the fuel tank.
Fill the oil tank (into the crankcase of the engi- ne) through the filling neck up to the oil level mark with motor oil class of SAE 15W40Check the oil level each time prior to starting the generator, whilst the generator must be standing on a horizontal surface.

WARNINGS

When handing oil, use suitable water-resistant protective gloves because oil is absorbed through the skin and is damaging to health.

ATTENTION

In the event that there is no oil in the oil tank, the oil sensor will prevent the generator from starting as prote-ction against damaging the engine.
The generator is supplied without oil and thus prior to first putting it into operation, it is necessary to fill it with oil so that the gauge on the oil cap (dipstick) is fully submerged in oil when fully screwed in. For the purpose of pouring oil into the oil tank, screw open the filling cap and using a funnel pour motor oil into the oil tank up to the level marked in the following figure.
Use quality motor oils intended for lubricating four- – stroke air-cooled petrol engines, e.g. Shell Helix HX5 15 W-40, Castrol GTX 15 W40 or their equivalents, with an SAE 15W40 viscosity class. Oils with a SAE 15W40 viscosity class ensure good lubrication proper-ties at the temperatures in our climatic conditions (in temperature range of -20°C to +35°C). Class SAE 15W40 oils can be purchased at fuel stations. Only quality motor oil may be used in the generator. Using other types of oils, e.g. food-grade oil or pneumatic tool oil, or used automotive oil, etc. is forbidden.
Never use oils intended for two-stroke engines in the generator!

WARNING
When adding or replacing oil, do not mix motor oils of various SAE classes or oils of the same SAE class from various manufacturers.
RECOMMENDED SAE MOTOR OIL VISCOSITY CLASSES BASED ON AMBIENT TEMPERATURES (°C)

The graphspecifies the motor oil classes for the given temperature range in the case that Class SAE 15 W40 motor oil is not available.
Check the oil level on the gauge (dipstick) after screwing it out of the oil tank.
Only check the oil level in the oil tank when the gene-rator is standing on a horizontal level and only after an extended period of time after the engine is turned off (at least 15 minutes). If you perform the oil check too soon after turning off the generator, not all the oil will have flowed down the walls of the crankcase and the oil level reading will not be reliable.

Check the condition air filter.

Check the air filter for clogging and its condition every time before putting the generator into operation (the inspection and maintenance plan is provided in chapter Cleaning and maintenance). Remove the air filter cover ,remove the filter and inspect its condition, i.e. check whether it is clogged, damaged, etc. Clean the filter after every 50 motor hours and in the event of operation in dusty environment after every 10 motor hours or more frequently according to the instructions further provided in chapter Cleaning and maintenance. In the event of significant clogging or wear and tear, replace it with a new original filter (the part number of the air filter is provided in table 1). A clogged air filter or operation of the generator without the air filter will result in damage to the carburettor and the engine. A clogged air filter prevents the supply of a sufficient amount of combustion air to the engine and leads to the carbonization of the engine, spark plug and exhaust pipe.

Through the strainer in the petrol tank filling opening pour clean lead-free car petrol without oil.

Always pour fuel into the tank through the strainer that is inserted in the fuel tank opening. This will remove any potential mechanical particles contained in the pet-rol, which could clog the fuel system and carburettor.
Petrol is highly flammable and very volatile. Petrol or its fumes may very easily ignite, and therefore do not smoke when handling petrol and prevent access to any flame or spark sources. Do not pour petrol into the fuel tank while the engine is running and allow the generator to cool down before pouring it in.
Petrol is damaging to health. Therefore, prevent petrol from coming into contact with skin, breathing in its vapours and ingesting it. When handling petrol, use protective aids, i.e. waterproof gloves as well as safety glasses. Petrol is absorbed through the skin into the body.
Only add petrol in well-ventilated environments to pre- vent inhalation of fumes.

ATTENTION

Norm ČSN 65 6500 stipulates that unless fuel is stored in an enclosed air-tight, light-proof container at a temperature of 10-20°C, the recommended period for which the petrol is usable is 3 months.

Petrol deteriorates, meaning that the most volatile (flammable) components evaporate from the petrol and, likewise, when ambient temperatures fluctuate petrol may be contaminated by condensating air moisture, which based on the age of the petrol may result in problems with starting the engine, reduced power, increase carbonization of the spark plug, exhaust pipe, etc.

We recommend adding a petrol conditioner to the petrol (petrol dewatering fluid). It helps a great deal in the event of problems with starting, improves the characteristics of the pet- rol, extends the lifespan of the engine and reduces carbonization of the exhaust pipe. Petrol conditioner can be purchased at fuel stations. Based on our experience, a pro-ven conditioner is from the Wynn’s brand under the name DRY FUEL from the Belgian manufacturer. When using the conditioner, follow the instructions for its use that are pro-vided on the packaging of the product. Based on our experience, it is sufficient to add a smaller amount of conditioner to the petrol than specified by the manufacturer, however it also depends on the quality and age of the petrol, since the petrol may be deteriorated already when sold at the fuel station. Prior to using the petrol, allow the conditioner to act in the petrol for 15-30 minutes. In the event that the conditioner is added directly into the fuel tank of the generator, it is necessary to stir the blend by appropriately moving the generator, to enable the conditioner to act on the entire volume of petrol and to wait 15-30 minutes before starting the engine.
Monitor the amount of petrol in the fuel tank using the fuel level gauge.
Do not fill the fuel tank all the way up to the neck of the fuel tank. This will result in fuel spilling out when handling the generator even through the closed cap.
Never pour petrol into the generator while it is running and allow the generator to cool down before pouring it in.
Open the fuel supply into the carburettor by turning the fuel valve lever to the position of symbol “1” on the pictogram on the frame of the generator.
Wait a few moments before starting so that the petrol can flow into the carburettor.
Set the choke lever to the symbol position or to the position CLOSE.

Starting the generator

WARNING

Before starting up the generator, always check the generator for damage (unconnected wires, leaks in the fuel system, missing safety elements and components, etc.). Prior to using the generator for powering appliances, perform a preliminary test and make sure that there are no faults. In this way you can prevent injury, damage to the generator or the connected appliances.

WARNING

Before starting the generator, disconnect all connec- ted electrical devices from the power sockets or turn off the operation mode if they have one.

Set the power switch to the “ON” position .
Slightly pull out the handle of the pull starter and then tug it out quickly
- If the generator does not start, holding the handle with your hand allow it to return to its initial position and repeat the starting process.
  ATTENTION
- Do not release the handle of the manual starter, rather allow it to return to the initial position while holding it since releasing the handle suddenly from the pulled out position would result in a rapid return and this could cause damage to the starting mechanism.
After starting the generator, gradually move the choke lever to the symbol position or to position OPEN.

In the event that when moving the choke lever, the engine were to be throttled, immediately set the choke lever back to the initial position and wait a few moments and then attempt to again gradually move it to the position for operation of the generator.
To start a generator with a warm engine that has been running for an extended period of time, it may not be necessary to set the choke lever to the starting position. It may, however, be necessary to check this by performing a practical test in the event that the generator can-not be started with the choke lever set in the generator operating position.

ATTENTION

In the event that there is an unusual noise, vibrations or operation while the generator is running, immediately turn off the generator and identify and rectify the cause of this unusual operation. If the unusual operation is caused by a fault inside the device, have it repaired at an authorised service centre for the HERON® brand through the vendor or directly at an authorised service centre (service locations are listed at the HERON® gene-rators website address at the start of this manual).

Connecting electrical devices and generator load – capacity

Connect electrical devices intended for connection to standard electrical power distribution grid into the 230 V~50 Hz sockets.

WARNING

The generator must not be transported or moved to a different location while it is running. Turn it off before moving it.
For powering electrical devices it is necessary to respect the following conditions, otherwise the powered electrical devices or the generator may be damaged:
The total nominal (operating) power input of all the connected electrical devices must not exceed the nominal (operation) electrical power output of the generator. To determine the nominal power input of an electrical device, it is possible to use an affordable socket power input meter (a wattmeter). The total operating (rated) power output of the generator is under-stood to mean the total drawn power input of all the electrical appliances connected to the generator at a voltage of 230 V ~50 Hz.
Do not draw more than 3.5 kW from a single 16 A/230 V power socket.
Turn on (start / put into operation) electrical devices gradually one after the other with a time interval in between and not all devices at the same time. The large surge power input caused by all the connected electrical devices being turned on may cause a peak voltage spike and damage the connected electrical devices.
The generator must not be concurrently used for powering sensitive electrical devices (e.g. computer, TV, office equipment) and an appliance with a power electric motor, which has an impulse ramp- – up power input and fluctuating power input based on the load placed on the electric motor such as for example hand power tools, etc. since this may result in “peak” voltage spikes (fluctuations), which may damage sensitive electrical devices.
In the event that the generator is used as a backup electrical energy source for powering TN-C-S (TN-C) networks (i.e. fixed electrical grids in apartments, etc.), the connection of the generator must be performed only by an electrician with the necessary qualifications, since it must be put into balance with the IT network of the generator with the TN-C-S (TN-C) grid. The generator may be connected to a TN-C-S (TN-C) grid only via an overvoltage protection that is built into the TN-C-S (TN-C) grid. In the event of damages resulting from non-professional connection, the manufacturer of the compressor bears no responsibility.

INFORMATION ABOUT POWER INPUT OF ELECTRICAL DEVICES
ATTENTION

The power input specified on the rating label of the electrical device containing an electric motor is, in the case of most electrical appliances, the expression of the power of the electric motor, i.e. the load that the electric motor can handle rather than expressing the power input during standard method of use of the electrical appliance, since the value of the power input increases with the load placed on the electric motor. Power electric motors in hand power tools have a starting ramp up input power, which is greater than the power input when a standard load is applied to the electric motor, however, most of the time it does not reach the power input specified on the rating label of the electrical device or in exceptional circumstances exceeds it by up to 30 % of the stated value. When a standard operating load is applied to hand power tools, the power input is below the value specified on the rating label. For illustration, the starting power inputs and power inputs during standard use of certain power tools and the mini-mum required electrical power outputs of the generators required to power them are provided in tables 2 and 3.
A typical example of electrical devices that differ from the above-mentioned are those having a higher peak current draw, such as compressors with a pressure vessel, high pressure washers with a higher power input and likewise this may apply to certain electrical devices with electrical motors with an older year of manufacture (see the serial number on the rating label of the electrical device), the powering of which requires the selection of a generator with an approximately 1 to 2 kW greater electrical power output than the power input specified on the rating label of the electrical device (see table 3), since the more powerful alternator of the generator is able to cover the peak (surge) current draw.
In the event that a heating electrical device is connected to the generator and the total power draw approaches or is equal to the operating electrical power output of the generator, the specified electrical power output of the generator may not necessarily be achieved since, for example, a hot air gun with heat regulation has extremely rapid fluctuations in power input of up to 300 W per second (this behaviour also occurs when it is powered from the mains power grid) and the generator may not necessarily be able to handle such rapid fluctuations in power input, which manifests itself by a reduction in the electrical power output of the generator and power input to the heat gun. A heat gun without temperature regulation normally has a stable power input and this behaviour should not occur with it.
When selecting a generator based on its electrical power output, the deciding factor is the power input value specified on the rating label of the electrical device, the year of manufacture of the electrical device and the type of electrical device (compressor with a pressure vessel, etc.) and the number of intended electrical devices that are to be powered from the generator, since the power inputs of the individual electrical devices are added up. The deciding factor for the use of an electrical device with a power input that is approaching the electrical power output value of the generator should be the soft start function on the electrical device, which ensures a slower ramp up of the electric motor and thereby reduces the current spike that would otherwise not enable the given electrical device to be used with the intended generator with a lower electrical power output.
Before purchasing a generator or connecting an electrical device/s to the generator, to get a general ideal, first use a standard wattmeter (device for measuring electrical power consumption) both during the start up of the electrical device as well as when placed under the expected load from the mains power grid (see table 2 and 3) and if possible, check the use of this electrical device/s on a sample of the generator being considered, since a wattmeter may not necessarily be able to capture the peak current ramp-up the duration of which is less than a second.
In table 2, there is a drawn up overview of the power inputs of angle grinders with a cutting disc diameter from 115 mm to 230 mm with the use of tools of the provided specification according to the determined pur-pose of use of the angle grinders and requirements for the minimum electrical power output of the generators.

Note

Tables 2 and 3 refer to the digital inverter generators HERON® 8896216 and HERON® 8896217, which are not part of our offer. The only reason why they are included is that the described tests were performed on them and they cannot be entirely compared to the respective available models HERON® 8896218 and HERON® 8896219 for the following reasons. The current mode HERON® 8896218 (900 W/Max. 1 100 W) is equipped with better electronics than model HERON® 8896216 and handles loads better at full operating power output than the original model HERON® 8896216. The current model HERON® 8896219 (1850 W/Max. 2000 W) has compared to the original model HERON® 8896217 (1 600 W/max. 2000 W) a higher electrical operating power output. The described digital generator models HERON® 8896216 and HERON® 8896217 thus better express the required minimum electrical power output for the given load.
To illustrate power input under very intensive loads, the task of “grinding asphalt” with a wire cup brush was selected since it results in high friction, which increases power input.
In table 2, for the purpose of comparison of power input with larger angle grinders, for illustration angle grinders Extol® Premium 8892021 and Extol® Craft 403126 were used with a braided cup brush of diameter 85 mm, which is, nevertheless, too heavy for these angle grin-ders and it is not permitted to use these angle grinders with this brush as this would result in damage to the angle grinder. These angle grinders must be used with cup brushes of diameter 65 mm.
Table 3 then shows an overview of the specified power inputs on other electric power tools.

OVERVIEW OF POWER INPUTS ON OTHER ELECTRIC POWER TOOLS
AND THE MINIMUM REQUIRED ELECTRICAL POWER OUTPUT OF THE GENERATORS

Operating power input with saw blade without load: 1132 W
Operating power input when cutting wood: 1420 W
Starting power input: 542 W
Operating power input under intensive load: 842 W

ATTENTION

The power inputs of the electrical devices provided in table 2 and 3 were measured using a standard commercially available wattmeter and the provided value may differ based on the intensity of the load (e.g. by the exertion of pressure on the power tools during use). They illustrate the approximate power input values of standard expected use of the power tools, which can also be applied to other types of power tools (e.g. planers and others).
The listing of specific generator models serves only as an example from our offer for the purpose of illustrating the electrical power output of the generators. There are, however, also other models of our generator or other brands with the same electrical power output, which may be used. In the event that the power tools are put under greater load, it may become necessary to use a generator with a greater electrical power output than specified. The specified minimum electrical power output of the generators is for illustration purposes only and prior to the intended use of a specific generator, the operating power output of which approaches the specified power input on the electrical device being used, perform a measurement with a wattmeter and carry out an operational test on a sample generator based on the expected operating load of the electrical device (if possible).
From tables 2 and 3 it is evident that the generator HERON® 8896416 with an electrical out-put of 2.5 kW and max el. output of 2.8 kW is absolutely sufficient for powering the majority of electrical devices including power tools such as angle grinders, circular saws, as well as less powerful compressors, electric pumps, etc., under the condition that only a single power tool is connected to the generator (see over-view of power inputs and the usable generators farther in the text).
In the event that the current load of the circuit breaker is exceeded (see shut-off current of circuit breaker ltrips in table 1), the lever of this circuit breaker shall be “tripped” (the lever will be in the down position) and current supply to the electrical device will be interrupted, or the engine of the generator will be throttled if the electrical power output of the alternator is lower than the shut-off current of the circuit breaker. If this happens, disconnect the electrical device from the generator and do not connect this electrical device to the generator, but rather replace it with an electrical device with a lower current draw (lower power input) and then “reset” the circuit breaker again.
In the event that the generator starts to behave in a non-standard manner during operation (e.g. sudden reduction in rpm, non-standard noise, etc.), interrupt the supply of current to the power sockets using the circuit breaker with the electrical device connected, and if the manifestation of this non-standard operating behaviour is not remedied in this way, immediately turn it off by toggling the power switch to the “OFF” position and identify the cause of this non-standard behaviour. In the event that the reason for the non-standard operation is a fault inside the generator, arrange a repair of the gene-rator at an authorised service centre for the the HERON® brand.

Turning off the generator –putting out of operation

Set the circuit breaker of the generator to the “OFF” position (lever down).
Set the power switch to the “OFF” Position.
Disconnect all appliances from the outputs of the generator.
Shut off the fuel supply using the fuel valve by set-ting the lever to position “0” on the pictogram.

If it is required to quickly shut off the generator, first of all set the power switch to the “OFF” position and then set the circuit breakers to the “OFF” position. Then per-form all the remaining steps.

ATTENTION

Closing the fuel supply using the fuel valve is necessary, otherwise petrol could pass through the petrol lines to the engine’s cylinders, namely when trans-porting or handling the engine, and then it is necessary to have the engine’s cylinders cleaned out at an authorized service centre, for which the right of a cost-free repair does not apply.

Additional information for the use of the generator

CONTENT OF OXYGENOUS COMPOUNDS IN THE FUEL

The content of oxygenous compounds in lead-free car petrol must meet the current requirements of norm EN 228.
Under no condition prepare the fuel blend yourself but instead procure it only at a fuel station. Do not modify the composition of the purchased fuel (excluding the use of a fuel conditioner). Use only good quality lead- – free car petrol.

OIL SENSOR AND MONITORING THE OIL AMOUNT

The generator is fitted with an oil sensor that shuts off the engine when the oil level falls below a critical limit, and thus prevents damage to the engine resulting from insufficient lubrication. The presence of this sensor does not entitle the operator to omit regular checks of the amount of oil in the engine’s oil tank.
The oil sensor must not be removed from the generator.

DIGITAL METER OF OUTPUT VOLTAGE, FREQUENCY AND OPERATION HOURS.

The generator is equipped with a digital motor hours counter from the last start (the counter is automatically reset to zero when the engine is turned off) as well as a total motor hours counter (symbol “H”) from the first start of the generator, the output voltage (symbol “V”) and frequency (symbol “Hz”), see description of the front (control) panel of the generator.

It is possible to use the button on the counter to switch between the individual measured values.
GROUNDING THE GENERATOR

In terms of protection against dangerous contact voltage on non-live parts, the generator meets the requirements of the currently valid European Directive HD 60364-4-4 for protection by electrical isolation. The requirements of this directive are entered into national electro-technical norms of the given country (in the Czech Republic this is norm ČSN 33 2000-4-41 including valid annexes, if they exist).
Norm EN ISO 8528-13, which specifies safety requirements for generators, requires that the user’s manual of the generator includes the information that the genera-tor does not need to be grounded in the case where the generator meets the aforementioned requirements for protection by electrical isolation.
The grounding terminal with which the generator is equipped is used for unifying the protection between the circuits of the generator and the connected appliance in the case where the connected appliance has Class I. protection or the appliance is grounded, where it is then also necessary to ground the generator for the requirements of directive HD 60364-4-4 (in the Czech Republic it is norm ČSN 33 2000-4-41) to be met. Grounding must be performed using norm compliant grounding devices and must be carried out by a person with the required professional qualifications based on the conditions where the generator is located and operated.

USING AN EXTENSION CORD FOR CONNECTING APPLIANCES TO THE GENERATOR

The load capacity of the cables depends on the resistance of the conductor. The longer the cable used, the greater must be the cross-section of the conductor (wire/s). Due to electrical power losses, the greater the length of a cable, generally the lower is the operating performance at its end.
According to norm EN ISO 8528-13, when using extension cords or mobile distribution networks, the resistance value must not exceed 1.5 Ω. The total length of cables with a conductor cross-section of 1.5 mm2 (for a nominal current in the range > 10 A to ≤ 16 A) must not exceed 60 m. With a conductor cross-section of 2.5 mm2 (for a nominal current in the range > 16 A do ≤ 25 A) the length of the cable must not exceed 100 m (with the exception of cases, where the generator meets the requirements of protection by electrical isolation in accordance with annex B (B.5.2.1.1.) of norm EN ISO 8528-13. According to the Czech norm ČSN 340350, the nominal length of a flexible extension cable with a wire cross- – section of 1.0 mm2 Cu at a nominal current of 10 A (2.3 kW) must not be longer than 10 m, an extension cable with a core cross-section of 1.5 mm2 Cu at a nominal current of 16 A (3.68kW) must then be no longer than 50 m. According to this norm, the total length of a flexible power cable including extension cords should not exceed 50 m (if, for example, this is an extension cord with a cross-section of 2.5 mm2 Cu).
For reasons of cooling, the extension cord must not be wound up or wound on to a spool, but must be fully unwound along its entire length in order to be cooled by the temperature of the ambient environment.

DRAWING DIRECT CURRENT (DC 12 V, 8.3 A)

The 12 V/8.3 A DC power socket (see description of the control panel) is intended for recharging 12 V lead car batteries with a capacity of at least 70 Ah with the use of 12 V charging cables with crocodile clips.

Turn off the motor vehicle, turn off all turned on electrical devices inside the vehicle and take the key out of the vehicle’s ignition and turn off the generator if it is running.
Insert the charging cables into the 12 V DC socket on the generator.
- ATTENTION
- Only connect the 12 V DC charging output of the genera- tor to the car battery when the generator is not running.
Before connecting the charging cables to the car battery terminals, first identify which battery ter-minal is grounded, i.e. connected to the chassis (frame) of the vehicle.
On most modern vehicles the grounded negative electrode of the battery is marked with the symbol “-“. In this case, first connect the alligator clip with the red charging cable to the non-grounded posi-tive pole of the battery (“+”) and then connect the alligator clip of the black charging cable (“-“) to the chassis (frame) of the vehicle. Do not connect the alligator clip to the carburettor, fuel line or sheet metal parts of the chassis, always use massive solid metal parts of the frame or the engine block.
- In the event that the positive electrode of the battery is grounded, then first connect the black charging cable with the alligator clip (“-“) to the negative electrode of the battery and then connect the alligator clip with the red charging cable (“+”) to the chassis (frame) of the vehicle, whilst adhering to all the measures described above.
- Take care that the charging cables are correctly connected to the terminals of the car battery. Connect the clamp of the red cable to the positive terminal and the clamp of the black cable to the negative terminal of the car battery.
Start the engine of the generator.
- When charging batteries, follow the instructions of the battery’s manufacturer.
- Do not start the engine of the motor vehicle during the recharging process.
- In the event that these instructions are not followed, the generator and battery may be damaged.
  ATTENTION
- The generators do not have car battery over-charging protection and, therefore, regularly check the vol-tage on the car battery terminals using a voltmeter. The terminal voltage on the battery being charged should not be greater than 14.4 V. The 12 V DC power output of the generator is not intended for charging any other batteries than 12 V lead car batteries with a flooded electrode with capacity of at least 70 Ah.
  ATTENTION
- Hydrogen is produced during the car battery recharging process, which together with air creates an explosive mixture. Therefore, do not smoke during the recharging process and prevent access to any flame or radiant heat sources. Ensure sufficient venti-lation during the charging process.
- The battery contains a sulphuric acid solution, which is a strong caustic agent, which causes chemical burns and tissue damage. When handling the battery, use suitable protective equipment, as a minimum rubber gloves and safety glasses. Never eat or drink while handling the car battery.
- In the event that skin comes into contact with electrolyte, immediately wash it under running water and then wash with soap. In the event that this acid solution is ingested, drink 200 ml of clean unflavoured still water and immediately contact a medical doctor or the Toxicological information centre.
- In the event of a short circuit on the 12 V DC/8.3 A output (e.g. accidental connection of the alligator clips +/- of the charging cable), the direct current circuit breaker will be triggered (see description of the control panel). To restore current supply, first eliminate the cause of the short circuit and then press the circuit breaker button .
Turn off the generator before disconnecting the charging cables of the generator from the car battery.
First disconnect the alligator clip of the charging cable from the grounded pole of the car battery and then the alligator clip of the ungrounded pole of the car battery.

OPERATION AT HIGH ABOVE SEA LEVEL ALTITUDES

At a higher above sea level altitude (above 1,500 m a.s.l.) the fuel: air ratio changes in the carburettor towards flooding with fuel (insufficient amount of air). This results in a loss of performance, increased fuel consumption, carbonization of the engine, exhaust pipe, spark plug and more difficult starting. Operation at high above sea level altitudes also negatively affects exhaust fume emissions.
In the event that you wish to operate the generator at an altitude greater than 1,500 metres above sea level for an extended period of time, have the carburettor readjusted at an authorised service centre for the HERON® brand. Do not adjust the carburettor yourself!

ATTENTION

Even with the recommended readjustment of the generator’s carburettor, the performance nevertheless declines by about 3.5 % per every 305 m of above sea level altitude. Without performing the above-described readjustments, the loss in performance is even greater.
When the generator is operated at an above sea level altitude that is lower than for which the carburettor is set, the carburettor has a lower fuel mixture, which again results in a loss in performance. Therefore, it is necessary to readjust the carburettor.

Care and maintenance

Before commencing maintenance tasks, turn off the engine and position it generator on a rigid horizontal surface.
Allow the generator to cool down before perfor-ming maintenance (servicing) tasks.

ATTENTION

Only original spare parts of the manufacturer may be used for repairs of the generator.
Regular inspections, maintenance, checks, audits and adjustments in regular intervals are an essential pre-requisite for ensuring safety and for achieving high per-formance of the generator. Table 4 provides the plan of tasks that must be performed in regular intervals by the operator themselves and that may only be performed by an authorised service centre for the HERON® brand.
To exercise a claim to warranty repairs, it is necessary to present/provide documentation of proof of purchase and performed servicing inspections – tasks. These records are entered into the second part of the user’s manual designated as “Warranty and service”. Not presenting/providing servicing records will be deemed to constitute neglected maintenance, which will result in loss of guaran-tee according to the warranty conditions.
In the event of a malfunction on the generator and the submission of a claim to free warranty repairs, the failure to adhere to these service tasks represents grounds for rejection of the warranty on the basis of neglect of maintenance and non-adherence to the user’s manual.
To extend the lifetime of the generator, we recommend that a complete inspection is performed after 1200 hours of operation, including repairs, covering the following tasks:
- the same tasks according to the maintenance plan after every 200 hours and the following tasks that may only be performed by an authorised service centre for the Heron® brand:
- inspection of the crankshaft, piston rod and piston
- inspection of collector rings, carbon brushes of the alternator or shaft bearings

MAINTENANCE PLAN

ATTENTION:

Tasks marked with the X(3) symbol must be per- formed only by an authorised service centre for the HERON® brand and tasks marked with X(4) by a qualified inspection technician specialising in electrical devices, see below. Other tasks may be performed by the user themselves.

NOTES

(X1) Perform the first oil change after the first 5 hours of operation because there may be fine metal dust from the engine’s bores present in the oil, which may cause the oil sensor to short-circuit.
(X2) An inspection of the air filter must be performed each time before the generator is put into opera-tion, since a clogged air filter prevents the supply of combustion air into the engine, which leads to its clogging, etc. Clean the filter every 50 hours of operation according to the described procedure, Table 4 when used in a dusty environment clean the filter every 10 hours or more frequently depending on the dustiness of the environment. In the event of heavy soiling or wear and tear/damage, replace it with a new original part from the manufacturer (the air filter for the given generator model can be ordered under the number listed in table 1).
(X3) These maintenance points may only be performed by a service centre authorized for the HERON® brand. The performance of the tasks by a different service centre or by the user themselves will be assessed as unauthorised tampering with the product, the result of which is the voiding of the warranty (see Warranty conditions).
(X4) ATTENTION
According to current regulations in force for the inspection of electrical equipment, the inspection and checks of all types of generators may only be performed by an inspection technician qualified for electrical equipment, who is certified to perform these tasks, i.e. a knowledgeable person.
In the event that the generator is used in a commer-cial application then it is / necessary for the operator, in the sense of labour employment legal regulations and on the basis of actual operating conditions and potential risks, to draw up a plan for preventative maintenance of the generator as a whole. Mandatory audits of the electrical parts must be performed even on paid rental (hired) generators. In the event that the generator is used for personal tasks, it is in your interest to have the electrical parts of the generator inspected by an electrical inspector according to the schedule specified in table 4.
(X5) Inspect connection points and hoses for leaks.

MAINTENANCE OF THE CYLINDER COOLING FINS

Regularly check the engine cooling fins for clogging . In the event of heavy soiling, the engine may overheat, and the engine may be seriously damaged or a fire may result.

OIL CHANGE

Drain oil from a warm engine, since warm oil has a lower viscosity (flows better) and also a short time after the engine is turned off, to ensure that the oil flows off the walls of the crankcase.

Locate the generator on a suitable, elevated stand to enable a suitable container to be placed beneath the drain opening in order to capture the oil.
Screw out the cap of the oil tank (to provide an air supply) and the oil draining bolt from the oil tank and then allow the oil to drain out into the prepared container. Then, lightly tilt the generator to ensure that all the oil flows out.
After draining all the oil, close the drain opening and tighten the bolt firmly.
Fill the oil tank with new oil according to the instructions provided above in the user’s manual.
Screw the oil tank cap back on.

ATTENTION:

Wipe dry any spilled oil. Use protective gloves to pre- vent your skin coming into contact with oil. In the event that oil does comes into contact with skin, thoroughly wash the affected area with soap and water. Do not throw out unusable oil together with municipal waste, and do not pour it down the drain or on soil, rather take it to a household waste collection facility. Transport used oil in closed containers secured against impact during transport.

CLEANING/REPLACING THE AIR FILTER

A clogged air filter prevents air from flowing to the carburettor and blocks supply of combustion air. In the interest of preventing subsequent damage, clean out the air filter in accordance with the prescribed maintenance plan (table 4). When operating the generator in a dusty environment, clean the filter even more often.

WARNING

Never use petrol or other highly flammable substances to clean the air filter. There is a risk of a fire resulting from possible electro-static discharge from dust.
Never operate the generator without the air filter. Unfiltered combustion air will damage the carburettor and the engine. Wear and tear caused in this way are not covered by the free warranty repair.

Remove the air filter cover and take out the filter

ATTENTION
- In the event of significant soiling or damage, replace the air filter with a new original filter – the part number of the air filter is provided in table 1.
Hand wash the filter in a warm detergent solution in an appropriate container (not in the washing machine) and allow it to dry thoroughly Do not use organic solvents, e.g. acetone. Handle the filter gently so as not to damage it.
Allow the filter to dry thoroughly at room tempera-ture.
Allow the dry filter to soak up motor oil and squeeze out any excess, however do not wring it as this could tear it . The oil needs to be thoroughly squeezed out of the filter, otherwise it would prevent air from flowing through the filter. A greasy air filter increases the filtration effect.
Put the filter back in place and correctly put cover back on.

INSPECTION/MAINTENANCE/REPLACEMENT OF THE SPARK PLUG

For the problem-free starting and operation of the engine, the electrodes of the spark plug must not be clogged, the spark plug must be correctly set and installed.

WARNING

The engine and the exhaust pipe are very hot while the generator is running and for a long time after it has been turned off. Therefore, be very careful to avoid bur-ning yourself.

Take off the spark plug connector and remove the spark plug using the correct wrench key .
Visually inspect the exterior appearance of the spark plug.
- In the event that the spark plug has clogged electro-des, file them using sandpaper or steel brush if necessary .
- If the spark plug is visibly significantly clogged or if the insulator is cracked or it is peeling, replace the spark plug with a new one (the spark plug type is specified in table 1).
  Using a gauge, check that the distance between the electrodes is 0.6-0.8 mm and that the gasket ring is in order.
Then screw the spark plug back in by hand.
Once the spark plug is screwed in, tighten it using a spark plug wrench to compress the gasket ring. Note
- After hand tightening the new spark plug, it is neces- sary to turn it by approx. 1/2 a rotation to compress the gasket ring. If this is a reused older spark plug, it is only necessary to tighten it by 1/8 to 1/4 of a rotation.
- A spark plug is a consumable good, and its wear and tear is not covered by the warranty.
  ATTENTION
- Make sure that the spark plug is well tightened. An incorrectly tightened spark plug clogs and heats up significantly and could seriously damage to the engine.
Place the spark plug connector back on to the spark plug so that it clicks in place.

MAINTENANCE OF THE PETROL FILTRATION STRAINER IN THE REFILL NECK OF THE FUEL TANK

Screw open the fuel cap and remove the strainer inserted in the neck of the fuel tank.Rinse the strainer in any non-flammable cleaning agent (e.g. detergent solution), or it is also possible to use a brush with plastic bristles and then rinse the strainer under clean water and allow it to dry thoroughly so that water does not come into contact with petrol. In the even that the strainer is excessively soiled, replace it with a new original one.
Return the cleaned strainer back into the neck of the fuel tank.
Put the fuel tank cap back on and tighten it firmly.

PURGING THE CARBURETTOR

Shut off the petrol supply to the carburettor using the fuel valve (position 0 on the pictogram).
Place an appropriate container underneath the drain bolt of the carburettor and then screw out the drain bolt of the carburettor and drain the dirty material into the prepared container. ATTENTION
- Petrol will start flowing out of the loosened screw. Purge the carburettor ideally outdoors since petrol fumes are damaging to health. Likewise, use appropriate waterproof protective gloves to prevent the skin from being sprayed with petrol. Petrol is absorbed through the skin into the body! Purge the carburettor away from any sources of flames and do not smoke.
To purge the carburettor, open the fuel supply using the fuel valve for a few moments to allow any dirty material to flow out into a container. Then close the fuel valve again to shut off the fuel supply.
Then screw the carburettor drain screw with the gasket washer back in and tighten firmly. After opening the fuel valve, check that no fuel is leaking around the bolt. If fuel does leak, tighten the mud bolt, or if necessary replace the seal washer of the bolt.

ATTENTION

Hand the petrol with the dirty material from the carburettor in an enclosed container to a hazardous waste collection facility. Do no pour it down the drain, on soil or throw it out with communal waste.

ATTENTION

The user can perform the carburettor purging operation using the carburettor mud bolt themselves, however, any work on the carburettor may only be performed by an authorised service centre for the HERON® brand.
The air-fuel ratio and the carburettor are set by the manufacturer and it is not permitted to make any changes to these settings. Any amateur tampering with the carburet-tor settings may result in serious damage to the engine.

CLEANING THE SETTING TANK OF THE FUEL VALVE

This may only be performed by an authorised service centre for the HERON® brand.

MAINTENANCE OF THE EXHAUST PIPE AND SPARK CATCHER

Leave the de-carbonisation of the exhaust and clea-ning of the spark catcher to an authorised service centre for the Heron® brand.

Transport and storage

The engine and the exhaust pipe are very hot during operation and remain hot for a long time after the generator is turned off, therefore, do not touch them. To prevent burns during handling and combustion hazards during storage, allow the generator to cool down before handling and storing it.
TRANSPORTING THE GENERATOR

Transport the generator exclusively in a horizontal position, suitably secured against movement and impacts in the transportation area.
Set the motor shut-off switch to the “OFF” position.
The fuel supply valve must be closed and the fuel tank lock must be firmly pulled tight.
Never start up the generator during transport. Always take the generator out of the vehicle prior to starting it.
When transporting it in an enclosed vehicle, always keep in mind that under strong solar radiation and a higher ambient temperature inside the vehicle, tem-perature will increase extremely and there is a risk of combustion or explosion of petrol fumes.

BEFORE STORING THE GENERATOR FOR AN EXTENDED PERIOD OF TIME

When storing it, ensure that the temperature does not fall below -15°C or increase over 40 °C.
Protect it against direct sunlight.
Drain all fuel from the fuel tank and fuel hoses, and close the fuel valve.
Purge carburettor.
Change the oil.
Clean the external part of the engine.
Screw out the spark plug and allow approx. 1 teaspoon of motor oil to flow into the cylinder, and then pull the handle of the manual starter 2-3×. This will create an even protective oil film in the area of the cylinder. Then screw the spark plug back in.
Pull on the handle of the manual starter and stop the piston in the top end position. In this way, the exhaust and suction valve will remain closed.
Place the generator into a safe dry room.

Diagnostics and troubleshooting potential faults

ENGINE WILL NOT START

Is the power switch in the “ON” position?
Is the fuel valve for the supply of the given fuel open?y Is there sufficient fuel in the tank?
Is there a sufficient amount of oil in the engine?
Is the ignition cable connector connected to the engine’s spark plug?
Is the spark plug generating a spark?
Do you have old stale petrol in the fuel tank? (Add a petrol conditioner to the petrol and stir it in by moving the generation or by pouring another portion of the fuel over it and allow it to act, see fig. 5. chapter IV.)

If the engine still will not start, purge carburettor (see above). If you are unable to remedy the fault, have the repairs performed at an authorised service centre for the HERON® brand.
SPARK PLUG FUNCTION TEST
ATTENTION

First ensure that there is no spilled petrol or other flammable substances in the vicinity. When testing functionality, use suitable protective gloves. When wor-king without gloves there is a risk of injury by electrical shock! Before removing the spark plug, make sure that the spark plug is not hot!
Screw the spark plug out of the engine.
Seat the spark plug into the ignition connector (“cap”). y Move the power switch to the “0N” Position.
Hold the thread of the spark plug against the body of the engine (e.g. on the cylinder head) and pull on the handle of the pull starter.
If there is no sparking, replace the spark plug with a new one. In the event that no sparking occurs even with the new spark plug, it is necessary arrange a repair at an authorised service centre. If the spar-king is in order, reinstall the spark plug and conti-nue starting the engine according to the manual.

If you are unable to start the engine even after this, have the repairs performed at an authorised service centre for the HERON® brand.

Safety instructions for using the generator

Electrical generators may present risks that are not discer-nible to amateurs and children in particular. Safe operation is possible with a sufficient knowledge of the functions of electrical generators.
Basic safety information

Protect children by ensuring that they remain at a safe distance from electrical generator.
Fuel is flammable and ignites easily. Do not pour fuel into the generator while the engine is running. Do not pour fuel into the generator while smo-king a cigarette or in the vicinity of an open flame. Prevent fuel from spilling.
Certain parts of combustion engines are hot and may cause burns. Pay attention to warnings on electrical generators.
Engine exhaust fumes are toxic. Do not use electricity generators in unventilated rooms. In the event that electricity generators are located in unventi-lated rooms, other fire and explosion prevention requirements must be adhered to.

Electrical safety

Prior to using electricity generators and their electrical equipment (including cables, power sockets, etc.) they must be inspected to ensure that they are not damaged.
This electricity generator must not be connected to other power supply sources such as electrical power grids. In special circumstances, where the generator is intended to serve as a stand-by backup to existing electrical systems, such a connection must be performed only by a qualified electrician, who must take into consideration the differences between the operating equipment utilizing the public power grid and the operation of the electricity generator. In accordance with this part of norm ISO 8528 the differences must be specified in the user’s manual.
Protection against injury by electrical shock depends on the circuit breakers that are specially adapted to the electricity generator. In the event that circuit breakers need to be replaced, then they must be replaced with circuit breakers with identical parameters and performance characteristics.
Due to the significant mechanical strain place on them, only durable and flexible cables with rubber insulation (meeting the requirements of norm IED 60245-4) may be used.
If the electricity generator meets the requirements of the protective function “protection by electrical isolation” in accordance with annex B, B.5.2.1.1. EN ISO 8528-13 grounding of generators is not necessary (see paragraph grounding of the generator).
When using extension cords or mobile distribution networks, the resistance value must not exceed 1.5 Ω. The total length of cables with a conductor cross-section of 1.5 mm2 must not exceed 60 m. With a conductor cross-section of 2.5 mm2 the length of the cable must not exceed 100 m (with the exception of cases, where the generator meets the requirements of the protective function “protection by electrical isolation” in accordance with annex B, B. 5.2.1.1. EN ISO 8528-13). Extension cords must be unwound along their entire length for the purpose of cooling by ambient air.
Selection of the protective arrangement, which must be performed based on the characteristic of the generator, operating conditions and the diagram of grounded connections determined by the user. These instructions and user’s manual must contain all the information necessary for the user to be able to correctly perform these protective measures (information about grounding, permitted lengths of connecting cables, additional protection devices, etc.).

WARNING

The user must adhere to the requirements of directives related to electrical safety, which relate to the location where the electricity generator is used.
Never start the equipment in an enclosed or partially closed area and under conditions of insufficient cooling and access to fresh air. Running the generator in the vicinity of open windows or doors is not permitted due to the inadequate extraction of exhaust fumes. This also applies when using the generator in trenches, shafts, outdoor holes, where exhaust fumes fill up such areas because they are denser than air and therefore are not well ventilated out of such areas. This may result in poisoning of persons working in these areas. Exhaust fumes are poisonous and contain toxic carbon monoxide, which is a colourless and odourless gas that may result in loss of consciousness when inhaled and possibly also death.
The safe operation of the generator in an enclosed or a partially enclosed area must be assessed and approved by respective government safety departments (fire protection, extraction of fumes, noise level, etc.), which are able to evaluate all the risks set and evaluate all acceptable limit values of risk factors, otherwise it is not permitted to operate the engine in these areas.
Petrol is flammable and poisonous, including its vapours. Therefore, prevent fuel from coming into contact with skin, breathing in vapours and ingesting it. Handle petrol and refill the fuel tank in well ventilated areas to prevent inhaling petrol vapours. While performing such tasks, use suitable protective aids to prevent skin contact and potential spillage. When handling petrol, do not smoke or handle an open flame. Avoid contact with sources of radiant heat. Do not refill petrol while the engine is running. Turn off the engine and wait for all parts to cool down before refilling the tank.
In the event of a fuel spill, it must be dried up and the fumes ventilated prior to starting the generator.
Before starting the generator, the operator must be tho- roughly acquainted with all of its control elements, and namely then with the method in which the generator is turned off as quickly as possible in an emergency situation.
Do not allow anybody to operate the generator without prior instruction. Prevent the equipment from being operated by a person that is physically or mentally unfit, incapacitated under the influence of drugs, medication, alcohol or exhausted. Prevent children from using the generator and ensure that they do not play with it.
The generator and particularly the engine and exhaust pipe are very hot during operation and long thereafter and may cause burns. Therefore, heed all warnings in the form of symbols on the machine. All persons (children in particular) and animals must therefore remain at a safe distance from the equipment.
Never operate the generator with wet hands. There is a danger of injury by electrical shock.
When present in the direct vicinity of the generator, use hearing protection, otherwise irreparable hearing damage may occur.
In the event of a generator fire, it must not be extin- guished using water but rather with a fire extinguisher intended/suitable for extinguishing electrical installations.
In the event that exhaust gases or fumes from a fire are inhaled, immediately contact a doctor and seek medical treatment.
In the interest of ensuring sufficient cooling of the generator, operate it at a distance of at least 1m from buil-ding walls, other equipment or machines. Never place any items on the generator.
The generator must not be built into any structures.
Do not connect other types of socket connectors to the generator than those that correspond to valid norms and for which the generator is also designed. Otherwise there is a risk of injury by electrical shock or a fire hazard. The power cord (extension cord) of the used appliances must conform to valid norms. Due to the large mechanical stress placed on it, only use flexible rubber cables.
The overload and short circuit protection of the generator depends on specially adapted circuit breakers. In the event that it is necessary to replace a circuit breaker, it must be replaced with a circuit breaker with the same parameters and characteristics. Replacement may only be performed by an authorised service centre for the HERON® brand.
Only connect appliances that are in perfect condition to the generator, that do not exhibit any functional abnormalities. In the event that the appliance is exhibiting
a fault (it is sparking, running slowly, does not start up, is excessively noisy, emitting smoke…) then turn it off immediately, disconnect it and remedy the defect.
The generator must not be operated in the rain, in wind, in fog and at a high humidity, outside the temperature range of -15 ° to + 40 °C. Attention, high humidity and frost on the control panel may lead to a short circuit and death to the operator by electrical shock. The genera-tor must be located underneath a shelter during rain. Constantly protect the generator during use and storage against humidity, dirt, corrosive effects, direct sunlight and temperatures above 40°C and below -15°C.
The generator must not be operated in an environment with an explosive or flammable atmosphere or in an environment with a high risk of fire or explosion.
Never adjust the generator’s parameters (e.g. adjusting rpms, electronics, carburettor) and do not modify the generator in any way, e.g. extend the exhaust pipe. All the generator’s parts may only be replaced with original parts of the manufacturer, which are intended for the given generator type. If the generator is not working correctly, please contact an authorised service centre for the HERON® brand.
According to hygiene regulations, the generator must not be used during the night-time calm period, i.e. from 10 p.m. to 6 a.m.

Noise
WARNING

The here mentioned numerical values of the guaranteed acoustic power level meet the directive 2000/14 ES, however since the acoustic power level exceeds 80 dB (A), persons in the vicinity of the generator should use certified hearing protection with a sufficient level of protection. Despite the fact that there is a certain correlation between the values of emitted noise and noise exposure levels, it is not possible to reliably use them to determine whether other measures are necessary or not. Factors that affect the current level of noise exposure of workers include the properties of the rooms in which they are working, other noise sources, e.g. number of machines or other work process being performed in the vicinity and also the duration of the time for which the worker is expo-sed to the noise. Also, the permitted level of exposure may differ from country to country. Therefore, after the installation of the generator at a workplace, have the noise level measured by an authorised person to deter-mine the noise load placed on the worker so that a safe exposure time can be set.
