Water and cleaning system
The water is fed to the high-pressure cleaner under pressure (2-8 bar pre-pressure). A
float valve regulates the water flow in the storage tank. Then the water is sucked directly
from the storage tank by the high-pressure pump and forced with the adusted pressure
through the heat exchanger to the safety spray lance. The high pressure jet is formed by
the nozzle at the end of the safety lance.
Environmental, refuse disposal and water protection regulations
must be observed!
Lance with trigger 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 operating pressure. When the trig-
ger is released, the trigger gun closes and any further spraying of liquid from the lance is
stopped. The motor stops.
When actuating the gun once more the pressure control valve - safety valve closes and
the motor is started again. The pump resumes feeding water to the spraying lance with
the selected operating pressure. When the gun is closed, the water hammer opens the
pressure control valve - safety valve and the motor is switched off by the pressure
switch.
The trigger 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.
Total stop system
The machine is fitted with a Total-Stop-System. If the gun is closed for longer than
approx. 20 seconds, the machine switches off automatically, after 20 minutes the
machine moves to safety switch off and you must use the main switch to turn it back on.
The machine restarts automatically when the gun is operated, provided that the master
switch is on.
