suction height see chapter Technical data).
The water connection coupling is not required for vacu-
uming operation.
1. Fill the suction hose with water.
2. Screw the suction hose onto the device water con-
nection and hang it in a water source (e.g. water butt).
Vent the device
1. Switch the device on "I/ON".
2. Unlock the lever of the high-pressure gun.
3. Press the lever of the high-pressure gun.
The device switches on.
4. Allow the device for run a maximum of 2 minutes un-
til the water escaping from the high-pressure gun is
free of air bubbles.
5. Release the lever of the high-pressure gun.
6. Lock the lever of the high-pressure gun.

Operation

to the instructions in chapter Troubleshooting guide.
High-pressure operation
ATTENTION
Damage to painted or sensitive surfaces
Surfaces can be damaged when the jet is too close to
the surface or an unsuitable spray lance is used.
Maintain a minimum spray distance of 30 cm when
cleaning painted surfaces.
Do not clean car tyres, paint or sensitive surfaces such
as wood with the dirt grinder.
1. Insert a spray lance into the high-pressure gun and
lock it by turning it 90°.

2. Switch the device on ("I/ON").
3. Unlock the lever of the high-pressure gun.
4. Press the lever of the high-pressure gun.
The device switches on.
Operation with a washing brush
ATTENTION
Paint damage
Damage to surfaces through a dirty brush
Ensure that the washing brush is free from dirt or other
particles before using it.
Note
The device operates at low pressure when using wash-
ing brushes. This means that detergent can be mixed
with the water.
1. Insert the washing brush into the high-pressure gun
and turn by 90° to fasten it.
Operation with detergent
DANGER
Failure to adhere to the safety data sheet
Incorrect handling of the detergent can seriously dam-
age your health
Observe the safety data sheet of the detergent manu-
facturer, in particular the instructions on personal pro-
tective equipment.
