Troubleshooting
!
Danger of electric shock!
Repair work on the appliance may only be performed by the authorized customer service.
Appliance does not work
-
Please check whether the voltage specified on the typeplate corresponds to that of the power
source.
-
Check the power cord for damages.
Appliance does not achieve the operational pressure
-
Deaerate the appliance: allow the pump to operate without the high-pressure hose until bubble-
free water emerges from the high-pressure outlet. Then reconnect the high-pressure hose.
-
Clean the sieve in the water connection (it can be easily removed using flat pliers).
-
Check the inlet water flow rate.
-
Check all supply lines to the pump for leaks or clogging-up.
Strong pressure variations
-
Clean the high-pressure nozzle. Remove dirt from the nozzle boring using a needle, and then
rinse the nozzle with water.
Pump leakage
-
A slight leakage of the pump is normal. If you detect an excessive leakage, please contact the
authorized customer service.
Detergent is not taken in
-
Clean the filter of the detergent suction hose.
Spare Parts
A selection of the most common spare parts numbers is listed at page 27 of these operating

General Informations
Safety Equipment
When the spary gun is closed, the overflow valve switches off the appliance via a pressure-
operated switch. The overflow valve is also a safety device against exceeding the maximum
allowable working pressure.
Guarantee
The terms and conditions of guarantee issued by a national Kärcher Company are valid in the
relevant country.
If the appliance malfunctions in any way, the fault will be rectified free of charge within the
period of the guarantee provided the malfunction is due to faulty material or a manufacturing
error and all the terms and conditions are met.
Pull the trigger until there is no more pressure in the appliance, and secure the trigger with the
safety ratchet against unintentional opening.
The appliance should be rinsed clean after detergent has been used. To do this, suspend the
detergent suction hose in a container of clean water, and run the pump for approx. 1 minute.
Frost will destroy an appliance which has not been completely emptied of water. Ideally, the
appliance should be stored in a frost-free room.
