Range of applicationThismachinemayonlybeusedforcleaningfacades,vehicles,containers,pavementslabs,stables,machinesandsmilarobjects.

InspectionsThemachinemustbeinspectedaccordingtothe“GuidelinesforLiquidSprayDevices”atleastonceevery12monthsbyaqualifiedperson,toensurethatcontinuedsafeoperationisguaranteed.Theresultsoftheinspectionaretoberecordedinwriting.Thismaybedoneinanyform.Forinspectionreportsseepages54-55.

High-pressure cleaners used for commercial purposes have to be checked by a qualified person at least every 12 months!

Accident preventionThemachineisdesignedforaccidentstobeimpossible(ifusedaccordingtotheseinstructions).Pleasereadsafetynotesincludedintheseinstructionscarefullybeforeusingthemachineandactcorrespondingly.Operatingstaffhastobeinstructedaccor-dingtothismanual.The“GuidelinesforLiquidSprayDevices”mustbecompliedwith.Setting up - Location

Neither set up and operate the machine in rooms where there is a risk of fire or explosion nor put it into puddles. Do not use the machine under water.

During the combustion process air is needed and exhaust gas emerges. If the machine 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 machine. Never stoop over this aperture and never reach into it. Emerging gases are extremely hot!

Do not jam the trigger of the gun during operation!When carrying through service and maitenance tasks the machine has to be cut off the power supply system. Put main switch to "0" and pull plug out of socket.

Never operate the machine if cables or other safety-relevant parts (e.g. excess pressure valve, high-pressure hose, spraying devices, etc.) are defective.

General rules

Safety notes

8 Safety notesNever operate the machine without supervision.The machine may only be operated by persons who have been instructed accordingly.Some parts inside the machine, all water conducting components and all metal parts of gun and lance are hot during hot water operation. Keep all hoods and protective covers closed during operation and never touch any metal parts of gun or lance. Persons operating the machine should wear the necessary protective clothing, i.e. waterproof clothing, rubber boots, safety goggles, headwear etc. It is prohibited to use the machine in close vicinity to people lacking suitable protective clothing.The high pressure spray can generate a high level of noise. If noise exceeds the maximum allowed levels, users and others in the vicinity must wear suitable ear protection.Do not spray against matter containing asbestos or other hazardous substances.Only use light heating oil EL (DIN 51 603) or diesel (DIN EN 590). The use of any other fuel may be hazardous and dangerous (risk of explosion).For safety reasons always switch the main switch to "0"- postion after having fini-shed the cleaning task (disconnection from power supply).

9Safety notes - This is prohibited!

Never allow children to use the high pressure cleaner!

Never direct the water jet at the machine itself!

The machine may not be placed within reach of the water jet spray mist!

Never direct the water jet at a power socket!

Never direct the high-pressure water jet towards the operator him-/herself or towards other persons, not even for cleaning clothing or shoes. Never direct the water jet at animals!

Only use power cables which are in perfect working order! Do not damage the power cable or repair it incorrectly!

Never pull the high pressure hose if it has formed kinks or “nooses”!Never pull the hose over sharp edges!

10 Please note - important! Lack of water

Required minimum quantities: 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 guarantee)

During high-pressure operation (above 30 bars) the temperature may not exceed 90 °C.

Steam level (90 °C - 150 °C)During steam operation 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.

In the case of machines with hose drums, the high pressure hose must always be unwound completely.

Only open the dosing valve, if the detergent sieve is placed in a liquid. Sucked air leads to destruction of the pump seals! No guarantee!

Keep detergent-ph-value neutral 7 - 9! Observe specifications of detergent manufacturer!e.g.: protective equipment, rules for waste water treatment etc.

Never suck in liquids containing solvents like varnish solvents, petrol, oil or similar liquid! Observe specifications of detergent manufacturers!

Seals inside the appliance are no resistant against solvents! The spray mist of solvents is highly inflammable, explosive and poisonous.

22 Decommissioning - frost protection01. Switch off the machine - main switch to „0“- position02. Cut off the water supply03. Open the spray gun briefly until the pressure is released04.

Oil leakage: If oil leaks out, go to the nearest customer service (dea-ler) immediately. (Environmental damages, transmission damages, loss of guarantee.)

In case of increased humidity or fluctuations in temperature develop-ment of condensed water is possible; if the oil turns grey, you must change it.

Care and MaintenanceThe machine must be disconnected from the power supply when ser-vicing work is being carried out. The main switch should be in position "0" and the plug out of the socket.

33Troubleshooting

34 Small repairs do it yourself No water from the nozzle but the gauge shows full pressure: Most likely the nozzle is blocked. (Insidethepressuregaugethereisnowaterbutafillingwithglycerintodampthevibrationofthepoin-ter.)

Proceeding:Switchoffthecleaner.Pullplugfromthesocket.

Operategunsevealtimestodecreasethepressure.Firstunscrewgunandlance,thenrinsehosefromanyresidues.

Ifthisprocedureisnotsuccessful,thenozzlehastobedismantledandcleaned(fromthebackside)orevenreplaced,ifnecessary.

The pressure gauge shows full pressure although the gun has been closed. The pressure switch valve switches constantly.Possible cause no.1: Leakage

36

Possible cause no. 2: The non-return valve is soiled or defectiveProceeding: Unscrewpumpoutlet.

Takeoutnon-returnvalvebodyandcheckforsoilingordamageoftheO-ring.

Replacenon-returnvalveifnecessary.

There is no guarantee if the pump is damaged by defective O-rings due to air induction or lack of water (cavitation).

Small repairs do it yourself

Pressure gauge shows little pressure, the water from the nozzle comes in squirts,The high-pressure hose vibrates.Most likely the valves are soiled.

Proceeding:Unscrewall6valves,oneaftertheother(hexagonalbrassscrews,3inarow,verticallyandhorizontally)
