Suctioning water from an open container
Screw suction hose with filter
(Order no. 4.440-238) to the water outlet.
Vent the unit before using.
To evacuate air from the unit, unscrew the
nozzle and leave the unit running until wa-
ter exits with no air bubbles.

back on.
Operating the unit
Danger!
Observe the relative safety regulations
when using the unit at filling stations or other
high-risk areas.
Caution!
Only clean engines in places which
have appropriate oil separators (protection of
the environment).
Caution!
Only wash animals with the low-
pressure fan jet (see "Selecting the type of
spray").
Operating with high pressure
The unit is equipped with a pressure switch.
The motor only starts up when the lever is re-
tracted.
Set the unit switch to "I". The indicator light
will go green.
Unlock the hand-held spray gun and retract
the lever of the gun.
Adjust operating pressure and flow rate
(+/–) by rotating the pressure/flow control
(infinitely variable).
At the lowest flow rate the waste heat from
the motor will heat the water to approx.
15 °C.
Selecting the type of spray
The handgun must be closed.
Rotate the housing of the nozzle until the
desired symbol corresponds with the mark-
ing.
Select pencil jet or fan jet by contactless
changeover:
rotate the spray lance, which is pointing
down at an angle of approx. 45°, to the left
or right.
Explanation of the symbols
High-pressure pencil jet (0°),
for particularly stubborn accumu-
lation of grime.
High-pressure fan jet (25°), for
dirt accumulation over a large
surface.
Low-pressure fan jet (CHEM)
for operation with detergent or for
cleaning at low pressure.
