Safety notes

User operating the high-pressure cleaner should wear the necessary protective clothing, i.e. waterproof clothing, rubber boots, safety goggles, ear protection headwear etc. It is prohibited to use the high-pressure cleaner in close vicinity to people lacking suitable protective clothing.
If noise exceeds the maximum allowed levels, users and others in the vicinity must wear suitable ear protection.
Use of high-pressure cleaners may result in aerosols being generated. An aerosol is a mixture of floating solid or liquid particles in a gas. Inhaling aerosol particles may cause damage to health. Employers  are under obligation to carry out a hazards assessment
in order to determine the necessary protective measures to prevent inhalation of aerosols as governed by the surface due to be cleaned in each case. Respiratory masks, Class FFP 2 or higher, are suitable for protection against aqueous aerosols.
Whenever the high-pressure cleaner is left unattended, the mains disconnect switch must always be switched off.
Do not spray against matter containing asbestos or other hazardous substances!
Never spray flammable liquids or liquids containing solvents such as paint thinners, petrol, oil or similar liquids! Explosion hazard due to spraying such materials!
Due to the high-pressure jet, damage may occur on the objects to be cleaned, e.g. car tires; therefore, a minimum distance of 30 cm is to be kept!
Prior to putting the high-pressure cleaners into operation, check its components (High-pressure hose, power supply cables, safety trigger gun) for any damage.
Replace defect or damaged components!
Only use high-pressure hoses, couplings and fittings recommended by Kränzle.
Only these accessories ensure safety of the equipment.
If use is made of an extension cable, this must be suitable for outdoor use.
In addition care needs to be taken to ensure that the cable is kept dry and that it is situated above the ground. We recommend the use of a cable drum capable of keeping the socket at least 60 mm above the ground.
Replacement of the power supply cables is only permitted by use of an original power supply cable of the manufacturer and must be performed by a qualified electrician.
Safety devices serve to protect the user and must never be de-activated or their function bypassed.
The high-pressure cleaner is to be properly used. The user is required to adhere to local requirements and to watch out for the persons in the danger zone!
If used in elevated positions where there is a risk of the unit falling to the ground, it must be secured against rolling away or tipping over.
The high-pressure cleaner is not designed for use by persons with restricted physical, sensory or mental abilities (including children)!
Some parts inside the machine, all metal parts of trigger gun with safety catch and lance are hot during hot water. Keep all hoods and protective covers closed during operation and never touch any metal parts of gun or lance without wearing appropriate protective gloves.
Use EL heating oil (DIN 51 603) or diesel fuel (DIN EN 590) only.
Using other kinds of fuel may cause considerable risks (explosions). When using high-pressure water for cleaning, make sure that there is a clearly noticeable recoil effect on the lance. Therefore ensure a firm footing (see technical data). Never allow children or untrained persons to use the high- pressure cleaner or to play with it!
Children must be kept under supervision to prevent them from playing with the equipment.

Never direct the high-pressure jet at the highpressure cleaner itself! The high-pressure cleaner may not be placed within  reach ofthe highpressure jet spray mist! Never direct the high-pressure jet at power sockets or any other electrical installations! Within theworking area, all live parts are to be protected from both water jet and spray mist. Always pay attention to the underbody lance resting on the surface! Bear in mind when using a curved or angled spraying lance that there is a significant amount of torque in the recoil!
(The underbody lance is available as optional accessory). Apply the safety catch on the safety trigger gun after each use in order to prevent unintentional spraying! Never direct the high-pressure jet at people or animals! Never direct the high-pressure jet at yourself or other persons, not even to clean clothing or shoes. Only use a power supply cable in perfect working order! Do not damage or improperly repair the power cable (tearing, squeezing, running over, …). Never pull the high-pressure hose if it has formed kinks or “nooses”! Never pull the high-pressure hose over sharp edges!

General rules

Intended use
This high-pressure cleaner is to be used solely for high-pressure water jet cleaning applications without detergents or low-pressure cleaning work with detergents (e.g. with a foam injector or washing brush).
Environmental, refuse disposal and water protection regulations must be observed!
Inspections
The high-pressure cleaner was finally inspected by the company Kränzle (refer to Kränzle final report).
The high-pressure cleaner must be inspected according to the “Guidelines for Liquid Spray Devices” at least once every 12 months by a qualified person, to ensure that continued safe operation is guaranteed. The results of the inspection are to be recorded in writing (see “Inspection reports” in these operating manual).
High-pressure cleaners used for commercial purposes have to be checked by a qualified person at least every 12 months!
The owner is to ensure that all safety-relevant components are in a serviceable condition before the high-pressure cleaner is used.

Accident prevention
The high-pressure cleaner is designed for accidents to be impossible if used correctly. The user is to be notified of the risk of injury from hot machine parts and the high-pressure jet. The “Guidelines for Liquid Spray Devices” must be complied with.

During the combustion process air is needed and exhaust gas emerges. If the high-pressure cleaner is operated in a confined space, precautions have to be taken to safely exhaust the fumes. Furthermore a sufficient ventilation has to be provided for.
Never shut the exhaust gas outlet on top of the If the high-pressure cleaner. Never stoop over this aperture and never reach into it.
Emerging gases are extremely hot!

Oil change The first oil change should be carried outafter approximately 50 operating hours, then every year or after 500 operating hours. If the oil turns grey or white, you must change the oil.
Remove the large right hood from the high-pressure cleaner and release the oil drain hose from the inside of the device. It is connected to the oil drain screw. Then open the red oil filling plug at the top of the silver oil housing and then the closure cap at the end of the hose. The oil is to be caught in the reservoir and disposed of in an approved manner. Close the end of the hose. Only then top up fresh oil.

New oil: 1 l
Kränzle High Performance Gear Oil
(Ord. no.: 400932)
Oil leakage
If oil leaks contact your nearest after-sales service (dealer) at once.
Failure to observe this instruction may cause damage to the environment and/or transmission gearbox.
In case of increased humidity or fluctuations in temperature development of condensed water is possible. If the oil turns grey or white, you must change it.

Decalcifying
Calcified heat exchanger use an unnecessary amount of energy because the water can only be heated slowly and the excess pressure valve feeds a part of the water back into the high-pressure pump circuit.
The calcified heat exchanger is known by the increased pipeline resistance.
Check pipeline resistance by disconnecting the lance from the trigger gun with safety catch and switching the high-pressure cleaner on. A full jet of water emerges from the gun. The high-pressure cleaner must be decalcified if the pressure shown on the stainless steel pressure gauge is greater than 50 bar.
Decalcify high-pressure cleaner as follows:

  1. Decouple the lance from the trigger gun with safety catch and decalcify it separately.
  2. Put detergent injector hose in a container with descaling agent.
  3. Set detergent valve on highest concentration.
  4. Set high-pressure cleaner at the main switch on “ON”.
  5. Hold the gun in a separate container and press the trigger gun with safety catch.
  6. Wait until descaling agent escapes at the trigger gun with safety catch (recognizable by whitish colour).
  7. Switch high-pressure cleaner at the main switch on “OFF” and let descaling agent work for 15 – 20 minutes.
  8. Switch high-pressure cleaner at the main switch on “ON” again and rinse it for two minutes using clear water.
  9. Please check whether the flow resistance has a lower value now again.
    If necessary, please repeat the decalcification process.

Decalcifiers are caustic! Observe the instructions for usage and accident prevention. Wear protective clothing to prevent the decalcifying agent from contacting your skin, eyes and clothing.

Fuel System
Your fuel may contain particles of dirt, or impurities or water may get into the tank during refuelling. To protect the fuel pump the high-pressure cleaner is equipped with a fuel filter. Check it regularly for dirt and exchange if applicable.
Check the tank for impurities on a regular basis. Clean the tank when necessary.
Empty the fuel tank using the drainage screw at the bottom of the tank.
Clean tank and fuel pipes thoroughly. Screw drainage screw back in.
Detergent and dirty fuel must be disposed of responsibly.
Check fuel system for dirt regularly.
No warranty is assumed for damage to the fuel system because of dirt.
The laws and regulations shall be observed and met by the operator.

Functional details

Thermostat

The thermostat controls the spray water temperature. After you switch on the device, “888” appears in both displays for approx. 1 second as a test of the functioning of the displays. The thermostat also monitors the minimum fuel level in the tank with a floating switch. If the level is below the minimum amount, the thermostat switches the oil burner off and the “OIL” sign flashes in the set temperature display (Pos. 1). If the unit displays “FLA” in the upper display, a malfunction in burning exists.

The thermostat has two operating modes:

  1. Temperature mode
    This mode is always activated when the unit is switched on or can be selected using the “°C°” button (Pos. 5). The red LED above the “°C” button and next to the set temperature display lights up.
    The desired “Set” temperature is set using the two buttons (+/-, Pos. 3+4) and can be read in the upper display (Pos. 1). If you press the button for a longer time, the set temperature is quickly adjusted in 5 °C increments.
    The last set value set is also stored after the unit is switched off and is available again immediately after switching back on. The current spray temperature can be read from the bottom display (Pos. 2)

  2. Percentage mode
    This mode is activated by pressing the “%” button (Pos. 6). The yellow LED above the “%” button and next to the set temperature display flashes.
    In the temperature control of high-pressure cleaners in temperature mode (“°C”), the water temperature is measured at the outlet of the heater, and the heater is switched on an off according to the temperature desired by the user.
    Due to the large amount of water in the heating coil, it takes a long time until the temperature sensor registers that the burner has switched on and the desired temperature has been reached.

This means that the temperature increases far above the desired value or falls far below the desired value. The innovative new percent mode now lets the user specify the switching duration of the heater in percent using the “+” and “-” buttons (Pos.  3+4) (100% being the max. temperature) rather than setting the desired temperature. Now the result of the setting must be checked by using the “Actual” temperature display. If the desired temperature has not yet been reached, the percentage must be increased.
By setting percentages of the heating duration, the temperature of the high- pressure jet is kept constant in a very narrow range.
The last value set is also saved after the unit is switched off in percent mode.
Operating hour meter
The cleaner is equipped with an operating hour meter. If during normal operation the momentary operating mode button ( “°C” or “%” ) is actuated for more then 2 seconds, the operating time of the pump is displayed for 5 seconds and afterwards the combustion time for 5 seconds as well. Thereafter the display shows the original values again. As long as the operating hours are displayed no further inputs on the monitor are possible.
The operating time is displayed in hours [ h ] either in the “TARGET” or in the „ACTUAL“ window. The 1000 and 100 hours are displayed in the „TARGET“ window and the 10, 1 and 1/10 hours in the “ACTUAL” window:
Pump operating time: Target-Display: P 9 9 Actual-Display: 9 9. 9 for 9 999,9h Combustion time: Target-Display: F 9 9 Actual-Display: 9 9. 9 for 9 999,9h
e.g.: F00 27.3 = Cumbustion time 27 hours and 18 minutes

Adjusting ignition electrodes For a smooth ignition, the setting of the ignition electrode must be controlled regularly.

Excess temperature sensor As an additional safety device the high- pressure cleaner is equipped with an excess tem- perature sensor inside the chimney. Should the safety devices as e.g. the float monitoring device be defectice and the burner continues to heat although the heating coil does not conduct away heat a destruction of the heating coil would be inevitable. As soon as the temperature inside the chimney exceeds 260 °C the excess temperature release triggers and cuts out the appliance. The display of the excess temperature sensor is located on the back of the switchbox inside the high-pressure cleaner.
Trooble shooting excess temperature
see chapter „Small repairs – do it yourself!“ in these operating manuel.
Attention!
Immediately contact our service in case of recurrence.
Heat exchanger
The water is forced through a heating coil by the high-pressure pump. The fuel pump sucks the fuel oil from the fuel tank via a fuel filter an and transports it to the injection nozzle. The heat exchanger is heated by a high-pressure fan heater. A ventilator draws in the cold, fresh air from the bottom end of the high-pressure cleaner and forces it upwards between the outer mantle and the inner mantle. In the process, the fresh air is pre-heated and the outer mantle of the heat exchanger is cooled.The pre-heated air is pressed through a mixing unit. Here finely atomized fuel is injected via a nozzle and mixed with the air. The electrodes located below then ignite the fuel-air mixture. The flame burns from top to bottom, turns round and the hot gas flows past the heating coil on its way back up. The burned gases collect in the exhaust chamber and are emitted from the exhaust gas outlet.

Please note: Lack of water Lack of water occurs more often than you probably believe. The more powerful a high-pressure cleaner is the greater is the danger that a lack of water occurs. If there is only an insufficient amount of water available, cavitation (water-gas mixture) arises inside
the high-pressure pump, which is normally noticed too late or even not at all. The high-pressure pump will be destroyed. Please check the available quantity of water by filling a bucket with liter scale for one minute.
Required minimum quantity of water (see technical data).
If the metered quantity of water is too small, you have to use a different water connection, guaranteeing the necessary output.
Lack of water leads to an accelerated wear of the joints (no warranty).
Never let the high-pressure pump run dry for more than 60 seconds.
Water supply

Please pay attention to the regulations of your waterworks company! In accordance with DIN EN 61770, the high-pressure cleaner may not be directly connected to the public drinking water supply lines. A brief connection however is permissible according to DVGW (German Association for Gas and Water Affairs) if a non-return valve with tube ventilator (Kränzle ord. no.: 410164) is built into the water supply. Once the water has passed through the non- return valve it is no longer considered as drinking water. Also indirect connection to the public drinking water supply lines is permissible by way of free emission in accordance with EN 61 770; e.g. by using a reservoir with a float valve. Direct connection to a non-drinking water supply line is permissible.

Insufficient quantity of electricity If there are too many collectors in your proximity connected to the network at the same time, the available voltage and the current intensity may decline. Consequently the motor of the high-pressure cleaner does not start or even blows. The power supply may also be insufficient if the power supply cable is too long or too thin. If extension cables are too long, this may lead to a voltage drop causing malfunctions or start-up difficulties.
Check the line fusing and have the voltage and the available current intensity checked by an expert in case of uncertainty (see technical data).

Electrical connection
The machine is supplied with a power supply cable. The mains plug must be fitted to a standard grounded socket with a 30 mA residual current operated device. Connection up to the mains must be carried out by a properly trained electrician and must comply with the requirements of IEC60364-1. The socket must be protected with a 16 A fuse on the mains side. When using an extension cable, this must have an earthed lead which is properly connected to the socket.
The conductors in the extension cable must have a minimum cross section of 1.5 mm². Plug connections must be of a spray-proof design, and may not be located on a wet floor. For extension cables of more than 10 m in length, the minimum cross-section must be 2.5 mm²! When using a cable drum, the power supply cable always must be unwound all the way.
Water and cleaning system
Water can be connected at mains pressure to the high-pressure pump.
A float valve in the water tank regulates the water inlet. Then, the water is sucked by the high-pressure pump from the water tank and supplied to the lance under pressure. The high-pressure jet is formed by the nozzle at the end of the lance.
Bypassing the water tank water can also be sucked directly out of a pressure- less container (see direct suction).
Environmental, refuse disposal and water protection regulations must be observed!
Safety jet pipe with safety trigger gun
The high-pressure cleaner can only be operated when the trigger of the safety deactivation trigger gun‘s trigger is actuated. When the trigger is pulled, the safety trigger gun opens. The liquid is then transported to the nozzle. The spray pressure increases and quickly reaches the operating pressure. When the trigger is released, the safety trigger gun closes and any further spraying of liquid from the safety jet pipe is prevented. The increase in pressure when the safety trigger gun is closed causes the pressure control valve-safety valve to open. The motor is switched off by the pressure switch. When thesafety trigger gun is opened, the pressure control valve/safety valve closes, the motor is started and the high-pressure pump resumes pressure spraying from the safety jet pipe
with the selected operating pressure.

The safety trigger gun is a safety device. Repairs should only be performed by qualified persons. Should replacement parts be required, use only components authorized by the manufacturer.
Pressure control valve/safety valve
The pressure control valve/safety valve protects the high-pressure cleaner from a build up of excess pressure, and is designed not to permit an excess pressure to be selected for operation. The limit nut on the handle is sealed with a spray coating. The operating pressure and spray rate can be steplessly adjusted by turning the handle.
Replacements, repairs, new adjustments and sealing should only be performed by qualified persons.

Motor protection switch
Motor is protected against overload by means of a motor protection switch. In case of motor overload or blocking, the motor of the high-pressure cleaner switches off automatically. If motor tends to switch off repeatedly, make sure to detect appears. Make sure to detect and remedy the cause of the failure.
Replacements and inspection work should only be performed by qualified persons when the high-pressure cleaner is disconnected from the power supply, i.e. with plug pulled out from the electrical socket.

Total stop system with delayed motor cut-off
When opening the trigger gun the motor is started via a total-stop system. When closing the trigger gun the motor is switched off only after 38 seconds and the device is in standby mode. The delayed switch-off is necessary because switching on and off motors frequently on high-pressure cleaners of this size may involve heavy load on the power network and cause increased wear of internal electrical parts. After 20 minutes in standby, the device will disconnect from the mains and must be turned on again by the main switch. The machine restarts automatically when the gun is re-opened, provided that the master switch is on.

Safety shutdown
If the high-pressure cleaner is accidentally not turned off after use or the trigger gun with safety catch is not used for 20 minutes, the high-pressure cleaner automatically changes into safety state by deactivation. By operating the main switch once more, the
device is activated again.
High-pressure hose and spray device
The high-pressure hose and spray device which are part of the therm-1-series equipment, are made of high quality material and engineered to conform with the operating conditions of the high-pressure cleaner and are duly labeled.

If replacement parts are required, only such parts that are authorized by the manufacturer may be used. The warranty is automatically void if spare parts of third-party providers are used! The high-pressure hose and spray device must be connected in a pressure-tight manner (without leakage).
The high-pressure hose may not be driven over, pulled excessively, or twisted. The high-pressure hose may under no circumstances be pulled over sharp edges. Defective high-pressure hoses must not be repaired (acc. to DIN 20022) but have to be replaced by new hoses approved by the manufacturer.
Prior to putting the high-pressure cleaner into operation make sure that all safety instructions be observed.

Putting into operation

  1. Install the mains cable holders with the screws.

  2. Install the water inlet filter at the water inlet.

  3. Prior to putting into operation fill fuel oil into the fuel tank. (fuel oil EL DIN 51 603 or diesel fuel DIN EN 590). Filling quantity 25 liters.

  4. For moving the high-pressure cleaner to the place of use, please release locking break.
    The high-pressure cleaner must not be pulled with connected water supply hose!

  5. The therm-1-series is a movable high-pressure cleaner with sturdy trolleys ideally suited for difficult terrain.
    For steering the high-pressure cleaner put the foot against the tipping support and then pull the device towards you.
    Please exclusively use the types of fuel listed above.
    Using other kinds of fuel may cause considerable risks (explosions).
    Neither set up or operate the therm-1-series in rooms where there is a risk of fire or explosion nor put it into puddles. Do not use the high-pressure cleaner under water. If, none the less, the high-pressure cleaner is operated in a hazardous area, the applicable safety regulations are to be observed.

  6. For high-pressure cleaners with hose drum, please loosen the fixation and then completely unwind the high-pressure hose. For high-pressure cleaners without hose drum the high-pressure hose included in the scope of the  delivery must be screwed with thepump outlet in a tight and pressure tight manner. Unwind high-pressure hose straight and without nooses. The high-pressure hose may leave  signs of abrasion on some floors.  Alternatively, please also find  non-marking high-pressure hoses  in our range.

    Prior to insertion, check plug coupling connection of lance for
    cleanliness (sand, dirt ..) and use clear water to clean, if necessary.
    Impurities may damage the sealing in the plug coupling.
    When using high-pressure hose extensions take care that the max. length of 20 m is not exceeded!
    Accessories may only be connected to a Kränzle-approved trigger gun with safety catch.

  10. Check water inlet filter for cleanliness prior to putting the high-pressure cleaner into operation.
    Unscrew the filter cup manually, take out the water inlet screen, flush thoroughly and clean with the remaining parts under clear water. If the screen is dirty, no water can run through and no pressure can build up.
    Check the water inlet sieve for damage. Do not operate the high-pressure cleaner without or with a damaged filter.

  11. Connect water hose to water inlet (minimum requirements; 5 m hose length, cross-section ¾”, 10 bar). The high-pressure cleaner may be connected to a water mains (1-10 bar pre-pressure) with either cold or hot water (up to 60 °C). The therm-1-series provides the opportunity of sucking in water out of a container (see direct suction).
    Be careful when using hot water!
    When running your high-pressure cleaner with hot water of 60 °C raised temperatures occur. Do not touch the metal parts of the high-pressure cleaner without safety gloves!

  12. For getting access to the interior fitting of the high-pressure cleaner, loosen screws at the cover. Remove cap carefully.
    Close cap properly prior to starting the washing procedure.

  13. Each time check oil level at the oil dip-stick prior to putting the high-pressure cleaner into operation. Oil level must reach until the upper edge of marking “OK“. See chapter „Care and Maintenance“ in these operating manual.

    Pull and release trigger of trigger gun with safety catch several times. Start with cleaning process.

  3. When starting the cleaning process do not aim the water jet towards the object you want to clean for at least 30 seconds. Maybe the water inside the combustion chamber has changed colour due to the rest time.

Usage as a hot water high-pressure cleaner

  1. Detergent valve must be closed.

  2. Switch on high-pressure cleaner with opened trigger gun (trigger pulled).
    Bleeding of the high-pressure cleaner:
    Pull and release trigger of trigger gun with safety catch several times.

  3. Set desired temperature at the thermostat. (Min. temperature 40 °C).
    On the subject of thermostat settings, see chapter “Functional details” in these operating manual.

  4. Switch on heater switch. The water is heated up and constantly kept at the set temperature.
    Start with cleaning process.

During high-pressure operation (above 30 bar) the temperature may not exceed 90 °C.
During steam operation (90 – 150 °C) the pressure may not exceed 30 bar! To reach the steam level (above 90 °C water temperature) adjust the pressure below 30 bar and choose by means of the thermostat the desired temperature of up to max. 150 °C.

Direct suction

Direct water extraction
Due to the suction capacity of its high-pressure pump (up to 2.5 m suction height, max. hose length 3 m) this high-pressure cleaner can suck in water for cleaning purposes from separate containers or ponds.
In this case the water tank must be bypassed.

  1. Unsrew connecting hose between high-pressure pump and water tank.
  2. Screw suction hose with suction filter  (ord.-no.: 150383) with connecting hose using a spreaded steel pipe fitting (ord.-no.: 46004).
  3. Put filled suction hose into the waterfilled container and start the cleaning job.
    Use clean water only!  Never suck in water containing chlorine! Do not suction air!

Prior to starting the first suction the high-pressure pump and the suction hose has to be filled with water!
Note
Depending on the water quality it may occur after a prolonged standstill that the valves get sticky. Consequently the high-pressure cleaner cannot properly suck in water from a container. In this case connect a hose with pressurized water to the pump inlet. Having started the high-pressure cleaner the pressurized water opens the valves and the machine resumes sucking in water from the container. Now you can carry on with your cleaning task as usual.

Applying additives

Suction of additives
Due to the water tank fitted to the therm-1-series it is now possible to directly suck the detergent into the high-pressure pump thus reducing output loss and increasing the efficiency considerably.

  1. Place chemicals filter into container with additives.
  2. Dosing of detergent is done by turning the detergent valve.
  3. By closing the detergent valve the supply of detergent is stopped.

Only open the dosing valve, if the detergent sieve is placed in a liquid! Sucked air leads to destruction of the pump seals of the high-pressure cleaner (No warranty)!
The additive must reveal a neutral pH value of 7-9. This machine has been designed for use of cleaning agents supplied or specifically recommended by the manufacturer. The use of other cleaning agents or chemicals may impair the safety of the machine. Observe and comply with relevant regulations, e.g. directives governing protective equipment, waste-water regulations, etc.
Attention solvents!
Never suck in liquids containing solvents like varnish solvents, petrol, oil or similar liquids! Seals inside the high-pressure cleaner are no resistant against solvents! The spray mist of solvents is highly inflammable, explosive and poisonous.

Taking out of operation

  1. Switch off the high-pressure cleaner
  2. Cut off the water supply
  3. Open the safety trigger gun catch briefly until the pressure is released
  4. Apply safety catch on the trigger gun
  5. Remove high-pressure hose and safety trigger gun
  6. Emptying high-pressure pump: Hold high-pressure hose and switch motor on until water jet stops escaping at the outlet.
  7. Pull the plug from the socket
  8. Clean high-pressure hose and wind up without loops, fix hose drum
  9. Clean and wind up the power supply cable
  10. Clean the water inlet sieve
  11. Apply locking brake
  12. Store high-pressure cleaners in frost-free rooms in winter

Frost protection
For protecting the high-pressure cleaner against frost please empty it completely.
Separate high-pressure cleaner from water supply and switch it on. By opening the safety trigger gun the high-pressure pump presses water out of the water tank. However, do not allow the high-pressure cleaner to operate without water for more than one minute. Fill the anti-freeze agent into the water box and turn on the high-pressure cleaner. Wait with opened gun until the agent spurts out of the nozzle.

Duties of owner
The owner is to ensure that all safety-relevant components are in a serviceable condition before the sprayer is used. (e.g., safety valves, hose and electric cables, spray equipment etc.)
Emission control legislation
With stationary installation, the emission levels of the machine must be checked once a year by a qualified organisation or person according to German law. The first inspection must be carried out four weeks after the machine is commissioned.
The owner is responsible for having the inspection performed.

Care and Maintenance

The machine must be disconnected from the power supply when servicing work is being carried out. The main switch should be in position “0” and the plug out of the socket.
Weekly, or after approx. 50 hours of operation
Oil level
Check the oil level of the high-pressure pump at the oil gauge rod. If the oil level is too low top up oil. The oil level must reach the upper edge of the “OK” mark. (Oil change – see chapter „General rules“ in these operating manuel. Change the oil if it has a grey or whitish appearance. The oil should be disposed of responsibly.
Water filter and fuel filter
Check the water filter in front of the float valve in the water tank and the fuel filter in front of the solenoid valve. Clean the filters if necessary.

Yearly, or after approx. 500 hours of operation:

  • Desulphurise and decarbonize the heating coil.
  • Check heating coil for calcification, decalcify if necessary.
  • Check the oil burner and ignition system.
  • Clean the oil nozzle, oil filter, solenoid valve and filter, clean and adjust the ignition transformer, ignition cable and ignition electrodes and replace defective parts.
  • Change the oil

Oil leakage
If oil leaks contact your nearest after-sales service (dealer) at once. (environmental damage, damage to the transmission).
In case of increased humidity or fluctuations in temperature development of condensed water is possible. If the oil turns grey or white, you must change it.

Small repairs – do it yourself

Problem
No water from nozzle although the high-pressure cleaner is running.
The stainless steel pressure gauge shows full pressure.
Cause
Most likely the nozzle is blocked.

The stainless steel pressure gauge shows full pressure, but from the nozzle comes only little water or no water at all.
(Inside the stainless steel pressure gauge is no water but a filling with glycerin to damp the vibration of the pointer.)
Proceeding:
Switch off the high-pressure cleaner. Pull plug from the socket. Operate safety trigger gun catch several times to decrease the pressure.
First remove the trigger gun with safety catch and the lance and flush the highpressure hose clear of potential residues.
Check water inlet filter for soiling. If the problem still exists, take wire (paper clip) and push through nozzle opening.
If this procedure is not successful, the nozzle has to be replaced.
Pull plug from socket prior to starting any repair work!

Problem
Irregular jet from nozzle.
The stainless steel pressure gauge shows low pressure.
Cause
Most likely the valves are soiled or sticky.

The stainless steel pressure gauge shows low pressure despite fully turned up pressure regulation. The water from the lance comes in squirts. The high- pressure hose vibrates.
(Inside the stainless steel pressure gauge is no water but a filling with glycerin to damp the vibration of the pointer.)

Proceeding:
Unscrew all 6 valves, one after the other (hexagonal brass screws, 3 in a row, vertically and horizontally) Take out valve body and O-ring by means of needle nose pliers. Check O-ring for damage. In case of a damage the O-ring has to be replaced. Take a wire (paper clip) and clean valves under running water.
Do not forget the O-ring during reassembly!

Problem
After closing the safety trigger gun the high-pressure cleaner
keeps switching on and off.
The stainless steel pressure gauge continuously displays full pressure.
Possible cause No. 1
Leckage.

Having closed the trigger gun with safety catch, the high-pressure cleaner must shut down and the stainless steel pressure gauge must show the permitted deactivation pressure (see rating plate). If not shut down and the stainless steel pressure gauge continuously shows full pressure (device does not switch to bypass), this could be due to leakage at the high-pressure pump, at the pressure switch, at the high-pressure hose or at the trigger gun with safety catch.

Proceeding:
Check connections from the high-pressure cleaner to the high-pressure hose and from the high-pressure hose to the safety trigger gun and also the connection between lance and safety trigger gun for tightness. Switch off the cleaner. Shortly press the trigger of the trigger gun with safety catch to decrease the pressure. Remove high-pressure hose, trigger gun with safety catch and lance and check the O-rings. If the O-rings are damaged they have to be replaced.
In case of a leakage there is no guarantee for possible consequential damages.

Problem
After closing the safety trigger gun the high-pressure cleaner keeps switching on and off.
The stainless steel pressure gauge continuously displays full pressure.
Possible cause No. 2
The non-return valve is defective.

Proceeding:
Switch off the high-pressure cleaner and pull plug from socket. Stop water supply.
Operate safety trigger gun catch several times to decrease the pressure.
Unscrew pump outlet. Remove check body and check O-Ring for soiling or damage. Also check seal seat inside pump housing for soiling or damage. If sealing rings are defective replace O-rings at once.
There is no guarantee if the high-pressure pump is damaged by defective O-rings due to air induction or lack of water (cavitation).
