Preparing the unit for use
Switching on the unit
Unpack the unit
Electrical connection
– When unpacking the unit, check the con-
tents of the packaging. If there has been
any damage in transit inform the dealer.
Caution!
The voltage specified on the model rat-
ing plate must correspond to the voltage sup-
plied.
– Do not dispose of the packaging with the
household rubbish, hand it in at the appro-
priate collection point for recycling.
Caution!
The maximum tolerable mains
impedance at the electrical contact point (see
Technical Data) must not be exceeded.
Check the oil level
Caution!
„ Read the oil level displayed while unit is at
a standstill. The oil level must be above the
two indicators.
Use an extension cable with a sufficient
cable cross-section (see Technical Specifica-
tions) and unwind it fully from the cable drum.
Activate the oil reservoir vent
„ Unscrew the fastening screw of the hood
For connected loads see model rating plate/
Technical Specifications.

down at an angle of approx. 45°, to the left
or right.
Explanation of the symbols
Operating the unit
High-pressure pencil jet (0°),
for particularly stubborn accumu-
lation of grime.
High-pressure fan jet (25°), for
dirt accumulation over a large
surface.
Danger!
!
Observe the relative safety regulations
when using the unit at filling stations or other
high-risk areas.
Caution!
Low-pressure fan jet (CHEM)
for operation with detergent or for
cleaning at low pressure.
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.
