Operating the unit
Danger!
Observe the relative safety regula-
tions 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-pres-
sure fan jet (see "Selecting the type of

The motor only starts up when the lever is
retracted.
„ Set the unit switch to "I". The indicator
light will go green.
„ Unlock the hand-held spray gun and re-
tract the lever of the gun.
„ Adjust operating pressure and flow rate
(+/–) by rotating the pressure/flow con-
trol (infinitely variable).
„ At the lowest flow rate the waste heat
from the motor will heat the water to ap-
prox. 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
marking.
„ Select pencil jet or fan jet by contactless
changeover:

down at an angle of approx. 45°, to the
left or right.
