2.2 Description of the device
The water passes through the water inlet and the behind mounted water filter, leading into the enginedriven high-pressure pump.
By the circulation valve the water passed through the high-pressure hose and the gun, is leaded
through the ray pipe and resigns through the high pressure nozzle.
The motor is turned ON and OFF with the motor protection switch and is protected against overload.
The circulation valve is a safety valve preset by the work, that regulates the working pressure to the
adjusted value and protects the pump from unacceptably high pressure..
Changes and settings are to be carried out only by an expert.
Any changes on the safety valve (breaking the seal) will void the warranty and conformity.
By turning the hand wheel (+/-) the working pressure is adjustable from the minimum to the maximum.
If your high pressure washer has additional equipments, please note the attached supplementary
sheets.
Operation with chemicals (optional)
Would you like to operate your high pressure washer using chemicals, so attach the chemistry hose with the suction filter in the fluid in the tank. Open the double-pipe valve at the
lance entirely. Approx. 10% of the chemical are added to the water, depending on nozzle
size and high pressure hose length.
