WWP 45 - Water pump Kärcher - Free user manual and instructions

USER MANUAL WWP 45 Kärcher

Do not refuel in confined spaces. Smoking and open flames are prohibited. Ensure that no fuel gets on hot surfaces during refuelling. Close the fuel tank cap after refuelling. Do not operate the device if fuel has been spilt. Move the device to another location and avoid generating sparks. Store fuel only in approved containers.

Do not store fuel in the vicinity of open flames or devices hav- ing an ignition flame or that gen- erate sparks (e.g. oven, heating boiler or water heater). Do not spray start spray into the air filter. ● Danger of fire. Maintain a minimum distance of 2 m between inflammable objects and the muffler. Do not operate the device in forests, bushy or grassy areas unless the exhaust pipe has been equipped with a spark catcher. Keep grass and other soiling substances away from the cooling fins. Do not operate the device if the fuel system is damaged or leaking. Check the fuel sys- tem regularly. Allow the device to cool down before storing in closed rooms. Danger of electric shock Do not touch the spark plug or ignition lead when the device is in operation. 몇 WARNING ● Health risk Exhaust gases are toxic. Nev- er breathe in the exhaust gas- es. Never operate the device in confined spaces. Ensure sufficient ventilation and ex- traction of the exhaust gases. Make sure that no exhaust gases are emitted close to air vents. Avoid repeated or prolonged contact with fuel or engine oil and do not inhale the fuel va- pours. 몇 CAUTION ● Danger of burns Do not touch any hot parts such as the muffler, cylinder or cooling fins. Danger of hearing damage Do not operate the device without a muffler. Check the muffler regularly and have a damaged muffler replaced. ATTENTION ● Risk of damage Use only spare parts from the original manufacturer. Old fuel can lead to deposits in the carburettor and impair the engine performance. Use only new fuel. Do not adjust any control springs or linkages that might increase the speed of the en- gine. Do not operate the device with the air filter removed. Do not pull the starter cord while the device is running. Ensure adequate ventilation so that the device does not overheat. Drain all water from the pump if there is a danger of frost. Symbols on the device 몇 WARNINGDanger of explosion, risk of fire.Petrol can cause fires or explosions if handled incorrect- ly. Read these operating instructions before using the de-vice.Do not operate the device in confined spaces or partially enclosed areas.Shut the motor down prior to refuelling.Fill the tank only up to 16 mm below the upper edge of the tank to allow room for expansion of the fuel.몇CAUTIONHot surfaceThe exhaust pipe of the device be-comes very hot during operation and can cause burns.Avoid touching the exhaust pipe.몇WARNINGRisk of eye injuries and hearing dam- age. Wear safety goggles and hearing pro-tection when operating the device.

Positioning the pump The delivery performance of the pump is heavily de- pendent on the operating conditions. Adhering to the following rules will ensure optimum performance. Keep the height difference between the water sur- face and the pump as small as possible. Position the pump so that the suction hose is a short as possible. A long pressure hose is better than a long suction hose. Do not unnecessarily long hoses. Connecting the hoses

1. Push the hose clip onto the suction hose.
