Water system
The water must be lead to the high pressure cleaner under pressure (2 – 8 bar
ad-mission pressure). A oat 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.

Lance with spray gun
The machine can only be operated when the safety trigger is 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 oper-
ating pressure.
When the trigger is released, the trigger gun closes and any further spraying of
liquid from the lance is stopped and the manometer must show 0 bar.
The increase in pressure when the trigger gun is closed causes the unloader
valve-safety valve to open. The pump remains switched on and continues to pump
liquid through the pump at reduced pressure. When the spray gun is opened, the
unloader valve - safety valve closes and the pump ressumes spraying from the
lance with the selected operating pressure.
The spray gun is a safety device. Repairs should only be per-
formed by qualied persons. Should replacement parts be re-
quired, use only components authorized by the manufacturer.
Detergent and caring system
The high pressure pump can also suck a de-
tergent/caring agent and mix it with the high
pressure jet. The additive is sucked through the
pump and brought in with the set pressure.
Insert the detergent hose into the detergent con-
tainer and open the detergent valve (6).
The detergent discharges with the water at the
high pressure nozzle.
Open the dosing valve, if the chemistry sieve is placed in a
liquid. Sucked air leads to destruction of the pump seals!!!
The rules concerning the environment, refuse and ground water
protection must be complied with!
