Operating Instruction
High Pressure Cleaner cold water, mobile
Series 3x3
6 Operation
Set device switch 0/I (3, Fig. 6 - 1) into position I. The high pressure
cleaner starts. The pump first delivers air from the high pressure nozzle.
After a short time, water then escapes.
Set the unloader valve (1, Fig. 6 - 1) to the desired operating pressure.
By turning the unloader valve clockwise, the operating pressure
increases - turning counterclockwise it decreases.
The operating pressure can be read off the pressure gauge (2, Fig. 6 - 1)
while the trigger gun (1, Fig. 6 - 2) is activated.
If the trigger lever on the trigger gun is released, the high pressure
cleaner switches to pressureless circulation operation. After approx.
30 sec. the device switches to stand-by mode. When the lever on the
trigger gun is pulled again, the motor and the pump restart
automatically.
General Information
If the device remains in stand-by mode for 20 minutes, the electronic
control switches the high pressure cleaner off as programmed.
To resume operation, move the device switch 0/I into position 0 and
then back to operating position I.

Lock the trigger lever (4, Fig. 6-2) of the trigger gun against uninten-
tional switching on using the locking lever (5, Fig. 6-2). Ensure that
the locking lever is correctly arrested in the notch for locking lever
(6, Fig. 6-2).
○
