Only with HD...M PU: High-pressure installation
The applicable national regulations for permanently in-
stalled high-pressure cleaning systems must be ob-
served.
1. Connect the device to the permanently installed pip-
ing using a high-pressure hose line.
2. Route the permanently installed piping with as few
changes in direction as possible.
3. Route the piping using padded loose and fixed clips
to compensate for pressure and thermal expansion.
4. Minimum line cross-sections:
a Pipelines: Nominal width DN 15 (1/2").
b Hose lines: Nominal width DN 6.

Operation

DANGER
Risk of injury from the high-pressure water jet
Never fasten the trigger and safety lever in the actuated
position.
Do not use the high-pressure gun when the safety lever
is damaged.
Push the safety latch of the high-pressure gun forwards
every time before starting work with the device.
Opening/closing the high-pressure gun
1. Opening the high-pressure gun: Actuate the safety
lever and trigger.
2. Closing the high-pressure gun: Release the safety
lever and trigger.
High-pressure operation
The device can be operated in a standing or lying posi-
tion.
Note
The device is equipped with a pressure switch. The mo-
tor only starts up when the high-pressure gun is open.
1. Device with a hose reel: Completely unroll the high-
pressure hose from the hose reel.
2. Set the power switch to "I".
3. Unlock the high-pressure gun by pushing the safety
latch of the high-pressure gun to the rear.
4. Open the high-pressure gun.
5. For devices with pressure and volume regulator: Set
the working pressure by turning the pressure and
volume regulator.

Recommended cleaning method
1. Spray the detergent sparingly on the dry surface and
let it work for a while (do not let it dry).
2. Rinse off the loosened dirt with the high-pressure
jet.
Rinsing out the foam lance
The foam lance must be flushed after use to prevent the
formation of detergent deposits.
1. Unscrew the container.
2. Pour the remaining detergent back into the original
packaging.
3. Fill the container with clear water.
4. Screw the container onto the foam nozzle.
5. Operate the foam nozzle for approx. 1 minute to
flush the detergent residue.
6. Empty the container.

Interrupting operation

1. Close the high-pressure gun, the device will switch
off.
2. Lock the high-pressure gun by pushing the safety
latch of the high-pressure gun to the front.
Note
The water pressure in the high-pressure hose is re-
duced by approx. 70% when the device is switched off.
This reduces the actuating force of the high-pressure
gun and extends the service life of the device.
Continuing operation
1. Unlock the high-pressure gun by pushing the safety
latch to the rear.
2. Open the high-pressure gun, the device will switch
on again.

Finishing operation

1. Close off the water inlet.
2. Open the high-pressure gun.
