Proper use

The power generator is suitable for devices that are intended to operate on a 230 V / 400 V AC or 12 V DC voltage source.
With household devices and electronic devices, please check the suitability according to the respective manufacturer’s specifications.
Attention! The power generator must not be connected to the mains supply as a domestic emergency power supply. It can cause damage to the power generator or other electrical devices.
AVR (Automatic Voltage Regulation):
The automatic voltage regulation system ensures that the voltage fluctuations of the power generator are within the range guaranteed by the power supply companies and thus do not pose a danger to electronic equipment. However, one should always check before use whether the consumption is suitable for operation with a power generator. In the case of extremely sensitive electronics, make enquiries with the manufacturer (such as televisions, mobile phones, tablets, laptops, etc.) beforehand, as a power generator produces a non-constant sine wave voltage due to the combustion engine.
The machine may only be used in the intended manner. Any use beyond this is improper. The user/operator, not the manufacturer, is responsible for damages or injuries of any type resulting from this.
An element of the intended use is also the observance of the safety instructions, as well as the assembly instructions and operating information in the operating manual.
Persons who operate and maintain the machine must be familiar with it and must be informed about potential dangers.
In addition, the applicable accident prevention regulations must be strictly observed. Other general occupational health and safety-related rules and regulations must be observed.
The liability of the manufacturer and resulting damages are excluded in the event of modifications of the machine.
Please note that our equipment was not designed with the intention of use for commercial or industrial purposes. We assume no guarantee if the device is used in commercial or industrial applications, or for equivalent work.

Safety instructions

We have marked points in the operating manual that impact your safety with this symbol: **
Furthermore, the operating manual contains other important text sections that are marked with the word “ATTENTION!”.
Attention! When using equipment, several safety warnings must be observed to prevent injuries and damage. For this reason, please carefully read this operating manual / safety instructions. If you hand the device over to another person, please hand over this operating manual / safety instructions as well. We accept no liability for accidents or damage that occur due to a failure to observe this manual and the safety instructions.

**WARNING
A failure to observe these instructions poses a danger of death or the risk of serious injuries.
**CAUTION
A failure to observe these instructions poses a minor to moderate danger of injury.
NOTE!**
A failure to observe these instructions poses a risk of damage to the engine or other property.

It is prohibited to make any modifications to the power generator.
The manufacturer’s preset speed must not be changed. Power generators or connected devices may be damaged.
Danger of poisoning! Exhaust gases, fuel and lubricants are poisonous, exhaust gases may not be inhaled.
Fire risk! Petrol and fuel vapours are highly flammable or explosive.
Engine exhaust gases are toxic. The power generator must not be operated in unventilated rooms. If the power generator is to be operated in well-ventilated rooms, the exhaust gases must be discharged directly outside via an exhaust gas hose.
Additional requirements for protection against fire and explosion must also be observed. Toxic exhaust gases can also escape when operating an exhaust hose. Because of the risk of fire, the exhaust hose must never be directed at flammable materials.
Never operate the power generator in rooms with highly flammable substances.
Hot surfaces! Danger of burns, do not touch exhaust system and drive unit.
Do not touch any mechanically moving or hot parts. Do not remove any protective covers.
Protective equipment! Use suitable hearing protection when you are near the device.
Only original parts may be used for maintenance and accessories.
Repair and adjustment work may only be carried out by authorised specialist personnel.
Protect yourself from electrical hazards.
Never touch the power generator with wet hands.
Only use approved and appropriately identified extension cables for use outdoors (H07RN).
If extension leads or mobile distribution networks are used, the resistance value must not exceed 1.5 Ω. As a guideline value, the total length of lines for a cross-section of 1.5 mm² should not exceed 60 m, and for a cross-section of 2.5 mm², 100 m should not be exceeded.
Never operate the power generator during rain or snowfall.
Always switch off the engine during transport and refuelling.
Fuel is combustible and highly flammable. Do fuel the unit during operation. Do not fuel the unit when someone is smoking or near open flames. Do not spill any fuel.
Do not refuel or empty the fuel tank near open light, fire or flying sparks. Smoking prohibited!
Do not use the power generator in a thunderstorm. – Danger of lightning strike!
Provide a secure, level place for the power generator. Turning and tilting or changing location during operation are forbidden.
Place the power generator at least 1 m away from walls or connected devices.
Children must be protected by ensuring that they stay a safe distance away from the power generator.
Some parts of the reciprocating internal combustion engine are hot and may cause burns. The warnings on the power generator must be observed.
Values specified in the technical data under sound power level (LWA) and sound pressure level (LpA ) represent emission levels and are not necessarily safe working levels. Since there is a correlation between emission and exposure levels, it cannot be reliably used to determine any additional precautionary measures that may be required. Factors influencing the current exposure level of the worker include the characteristics of the workspace, other noise sources, airborne noise, etc., such as the number of power generators and other adjacent processes and the length of time an operator is exposed to the noise. The permitted exposure level may also vary from country to country. Nevertheless, this information will enable the operator of the power generator to make a better assessment of the risks and hazards. If necessary, acoustical measurements should be taken after installation to determine the sound pressure level.
Warning! Comply with the electrical safety regulations applicable to the place where the power generators are used.
Warning! Consider the requirements and precautionary measures in case of re-supply of a system by power generators depending on the protective measures of this system and the applicable directives.
Power generators should only be used up to their rated power under the rated ambient conditions. If the power generator is used in conditions that do not comply with the reference conditions according to ISO 8528-8:2016, 7.1, and if the cooling of the engine or power generator is impaired, e.g. as a result of operation in restricted areas, a reduction in power is required.
Due to high mechanical loads, only durable rubber hose lines (per IEC 602454) or equivalent equipment should be used.
Observe the electrical safety regulations applicable to the place where the power generator is used.
Consider the requirements and precautionary measures in case of re-supply of a system by power generators depending on the protective measures of this system and the applicable directives.

Electrical safety

Prior to use, the generator and its electrical equipment (including lines and plug connectors) should be checked to ensure that there are no defects.
The power generating unit must not be connected to another power source such as the power supply of energy supply companies. In special cases where a reserve connection to existing electrical systems is provided, this must only be carried out by a qualified electrician who will take into account the differences between the operated equipment using the public mains and operation of the power generating unit. According to this part of ISO 8528, the differences in the operating manual must be specified.
Protection against electric shocks depends on the circuit breakers which are matched precisely to the power generating unit. If a circuit breaker must be replaced, this should be done using a circuit breaker with the same rating and performance characteristics.

ATTENTION: Use only E10 unleaded petrol as fuel.
Use of petrol
Danger to life! Petrol is toxic and highly flammable.

Only store petrol in containers (canisters) designed and tested for this purpose. The fuel tank caps must always be properly screwed on and tightened. Defective caps must be replaced for safety reasons.
Keep petrol away from sparks, open flames, permanent flames, heat sources and other sources of ignition. Do not smoke!
Refuel outdoors only and do not smoke while refuelling.
Before refuelling, switch off the combustion engine and let it cool down.
Petrol must be filled before starting the combustion engine. While the combustion engine is running or if the device is hot, the fuel tank must not be opened and petrol must not be filled.
Open the fuel filler cap carefully and slowly. Wait for the pressure to equalise and only then remove the fuel filler cap completely.
Use a suitable funnel or filler pipe for refuelling so that no fuel can spill onto the combustion engine and housing or lawn. Do not overfill the fuel tank!
To leave room for the fuel to expand, never fill the fuel tank beyond the lower edge of the filling nozzle. Observe additional information in the combustion engine user manual.
If petrol has overflowed, do not start the combustion engine until the petrol-contaminated area has been cleaned. Avoid starting the engine until the fuel vapours have evaporated (wipe dry).
Always wipe up spilled fuel immediately.
If petrol has got on clothing, it must be changed.
The tank cover must be properly screwed on and tightened after each refuelling operation. The device must not be put into operation without the original tank cover screwed on.
For safety reasons, check the fuel line, fuel tank, fuel filler cap and connections regularly for damage, ageing (brittleness), tight fit and leaks, and replace if necessary.
Only empty the fuel tank outdoors.
Never use beverage bottles or similar to dispose of or store operating materials, such as fuel. People, especially children, could be tempted to drink from it.
Never store the device with petrol in the fuel tank inside a building. Any fuel vapours produced can come into contact with naked flames or sparks and ignite.
Do not place the device and fuel tank near heaters, radiant heaters, welding machines or other sources of heat.

Risk of explosion!
If a defect is detected on the fuel tank, the fuel filler cap or on fuelcarrying parts (fuel lines) during operation, the combustion engine must be switched off immediately. Then consult a specialist dealer.
Battery safety

To avoid spark formation due to a short circuit, always disconnect the negative cable (-) from the battery first and reconnect it last.
Never smoke during work on the battery. Always keep sparks, naked flames and other heat sources away from the battery.
Special care must be taken when using jumper cables. Follow relevant instructions to avoid damage to the device (in particular, do not operate the starter for more than 10 seconds).
Never open the battery and do not drop it.
Always charge the battery in a closed room with good ventilation, dry and protected against the weather.
Do not short-circuit battery connections.
Deformed or defective (leaking) batteries must not be used and must be replaced and disposed of in an environmentally friendly manner. Observe the countryspecific regulations.
If the batteries are defective, liquid may leak out. Avoid contact! In case of accidental contact, rinse with water. If the liquid gets into your eyes, seek additional medical attention. Leaking battery fluid can cause skin irritation, burns and chemical burns.
Regularly visually inspect the connection cables on the battery for damage. Have damaged cables replaced by a specialist.
Never bypass the fuses. Never use a fuse with a rating other than the prescribed rating (amperes).

Residual risks
The device is state-of-the-art and has been built in accordance with the recognised technical safety rules. However, individual residual risks can arise during operation.

Health hazard due to electrical power, with the use of improper electrical connection cables.
Furthermore, despite all precautions having been met, some non-obvious residual risks may still remain.
Residual risks can be minimised if the “Safety Instructions” and the “Intended Use” together with the operating manual as a whole are observed.
Avoid accidental start-ups of the power generator.
Use the device in the way that is recommended in this operating manual. This is how to ensure that your power generator provides optimum performance.

– Eliminate possible sources of ignition, such as furnaces, hot water boilers with gas, gas dryers, etc.
NOTE!
Risk of damage!
If the product is not stored properly, the engine can be damaged.
– Store the product protected against dirt, dust and moisture.
14.1 Preparation for storage

Empty the fuel tank using a fuel extraction pump (see section 13.3).
Warning: Do not remove the petrol in enclosed spaces, near fire or when smoking. Petrol fumes can cause explosions and fire.
Carry out an oil change (see section 11.3).
To do so, remove the used engine oil from a warm engine and refill with fresh oil.
Remove the spark plug (20a).
Fill the cylinder with approx. 20 ml of oil from an oil can.
Pull the pull starter (17) slowly so that the oil protects the inside of the cylinder.
Screw the spark plug (20a) back in.
The ignition key (14) must always be removed from the ignition lock (14a) and stored securely to prevent unauthorised or improper use by children and other persons.
When the device is taken out of service for an extended period of time, before starting work on or near electrical components, disconnect the battery connection cable. We recommend removing the battery (9) and storing it fully charged in a dry and locked room.
