Water supply system
Thewatermustbelead to the high pressure cleaner under pressure (2–8barad-
mission pressure).Afloat valve regulates the water inlet. Then, the water is sucked
by the high pressure pump from the water tank and supplied to the lance under the
set pressure. The high pressure jet is formed by the nozzle at the end of the lance.
Detergent and caring system
Thehighpressure pump can also suckadetergent/caring
agent and mix it with the high pressure jet. The additive is
sucked through the pump and brought in with the set pres-
sure.

Only open the dosing valve, if the
chemistry sieve is placed in a liquid. Sucked air leads to de-
struction of the pump seals !!!

water protection must be complied with!

Lance with spray gun
Themachinecan only be operated when thesafetytriggeris squeezed.
When the lever is squeezed, the spray gun opens. The liquid is then pumped to the
nozzle. The spray pressure increases and quickly reaches the selected operating
pressure. For the deairing of the system open and close the gun quickly a few
times. When the trigger is released, the trigger gun closes and any further spraying
of liquid from the lance is stopped and the pressure gauge must show 0 bar.
Theincreasein pressure whenthetrigger gun isclosedcauses the unloader valve-
safetyvalveto open. The pumpremainsswitchedon and continues topumpliquid
throughthepump at reduced pressure. Whenthespraygun is opened, the unloader

The spray gun is a safety device. Repairs should only be
performed by qualified persons. Should replacement
parts be required, use only components authorized by the
manufacturer.
