Water and cleaning system
Water must be supplied to the high pressure pump under pressure or directly
sucked in out of a pressureless container. The water is then forced under pressure
by the high pressure pump to the lance. The high pressure jet is formed by the
nozzle at the end of the lance.
Environmental, refuse disposal and water protection regulations
must be observed!
Safety jet pipe with safety trigger gun
The high pressure cleaner can only be operated when the trigger of the safety
deactivation trigger gun‘s trigger is actuated. When the trigger is pulled, the
safety trigger gun opens. The liquid is then transported to the nozzle. The spray
pressure increases and quickly reaches the operating pressure. When the trigger is
released, the safety trigger gun closes and any further spraying of liquid from the
safety jet pipe is prevented. The stainless steel pressure gauge must show 0 bar.
The increase in pressure when the safety trigger gun is closed causes the pressu-
re control valve-safety valve to open. The motor is switched o by the pressure
switch. When thesafety trigger gun is opened, the pressure control valve - safety
valve closes, the motor is started and the high pressure pump resumes pressure
spraying from the safety jet pipe with the selected operating pressure.
The safety trigger gun is a safety device. Repairs should only be perfor-
med by qualified persons. Should replacement parts be required, use
only components authorized by the manufacturer.
