WARNING
Danger of burns and scalds by hot surfaces or water.
The device is designed for a water inlet temperature of up to 45 °C. During
operation with hot water inlet, surfaces of device parts or cleaning objects
may get hot (parts of pump, metal parts of spray lance etc.).
Touching hot surfaces or hot water can cause burns or scalding of the skin
surface. Avoid contact with hot water.
Make sure surfaces of device parts or water have cooled before touching.
Set device switch On/Off (2, 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 (4, 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 (3, 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 On/Off into position 0 and
then back to operating position I.
For safety reasons after completion of cleaning work
○
Switch off the device via the device switch On/Off (into position 0).
○
Lock the trigger lever (4, Fig. 6-2) of the trigger gun against
unintentional 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).
