– 3Safety devices serve for the protection ofthe user and must not be put out of opera-tion or bypassed with respect to their func-tion.The safety valve opens when the permissi-ble operating pressure is exceeded; waterflows back to the suction side of the pump.The safety valve is set by the manufacturerand sealed. Setting only by customer ser-vice.The thermo-valve opens when the permis-sible water temperature is exceeded andlets out the hot water into the open.The thermostat valve prevents the pumpfrom over-heating. DangerRisk of injury! Device, tubes, high pressurehose and connections must be in faultlesscondition. Otherwise, the appliance mustnot be used. Check oil level of the high pressurepump at the oil sight glass.Do not operate the appliance if the oil levelhas fallen below "MIN". Add oil if required (see technical speci-fications).Follow the instructions given in the sec-tion "Safety Notes"! Read the operating instructions of theengine manufacturer before start-upand follow the safety instructions care-fully. Fill the fuel tank with unleaded petrol.Do not use 2-speed mixture. Check oil level of the engine.Do not operate the appliance if the oil levelhas fallen below "MIN". If required, top up oil carefully. Connect high pressure hose and spraypipe to the hand spray gun. Install the nozzle on the spray pipe in sucha way that the marking is on the top. Tighten covering nut firmly. Connect the high pressure hose to thehigh pressure connection point of themachine.– For connection values refer to technicalspecifications WarningObserve regulations of water supplier.According to the applicable regula-tions, the appliance must never beused on the drinking water supplywithout a system separator. Use asuitable system separator manufactured byKÄRCHER; or, as an alternative, a systemseparator as per EN 12729 Type BA. Waterflowing through a system separator is con-sidered non-drinkable.CautionAlways connect the system separator tothe water supply, never directly to the appli-ance! Connect the supply hose to the waterconnection point of the machine and atthe water supply point (for e.g. a tap). Open the water supply.Safety DevicesSafety valveThermo-valve at the pumpStart upCheck oil level of the high pressurepumpMotorInstall hand spray gunWater connection14 EN
