Water Tanks with outlet connections

When connecting the pressure washer to a water tank with a 
suitable tap outlet, first connect the supply hose (not provid-
ed) to the tank outlet, open the tap to allow the water to dis-
place all the air in the hose and then connect to the pressure 
washer.

Wrong mains voltage

Check that mains voltage corresponds to 
specifications on the model tag

Motor protector has activated

Allow to cool for 15 minutes

Fuses blow

Fuses incorrectly rated

Change to a mains supply higher than the 
pressure washer amp consumption

Motor starts but no pressure

Nozzle partly blocked

Clean nozzle

Motor “sounds” but fails to start

Insufficient power supply

Check that the voltage of the mains pow-
