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
spray").
Operating with high pressure
The unit is equipped with a pressure switch.
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.
