4. Operating the cleaner
Danger! Observe the relative safety
regulations when using the cleaner 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 cleaner is equipped with a pressure switch.
The motor only starts up when the lever (2) is
retracted.
• Press safety switch (3) and retract lever (2).
• Set unit switch (17) to “I”.
• Adjust operating pressure and flow rate (+/–)
by rotating the pressure/flow control (13)
(infinitely variable).
Read off operating pressure on pressure gauge.
Selecting the type of spray
The handgun must be closed.
• Rotate the housing of the nozzle (22) until the
desired symbol corresponds with the marking:
High-pressure pencil jet for
particularly stubborn accumulation
of grime
Low-pressure fan jet for operating
with detergent or cleaning with
negligible pressure
High-pressure fan jet for dirt
accumulation over a large surface
Operating with detergent
Caution! Unsuitable detergents can harm the
cleaner and the object which is to be cleaned.
Use only detergents which are released by
Kärcher. Proportions of detergent to be used
and accompanying instructions should be
noted carefully. Use detergents sparingly out
of consideration for the environment.
Kärcher cleaning agents guarantee trouble-free
operation. Please seek advice or ask for our
catalogue of information sheets on cleaning
agents.
