Cleaning operations during which oil saturated
!
waste water is generated, such as engine cle-
aning and underbody cleaning, may only be per-
formed in cleaning locations that are equipped
with an oil separator.

!
luted acids and solvents! These include, for ex-
ample, benzene, paint thinner, or heating oil. The
spray is highly inflammable, explosive, and to-
xic. Do not use acetone, undiluted acids, and
solvents as they affect the materials used on the
appliance.

!
and glasses to protect yourself from return spray.
Never leave the appliance unattended as long as
!
it turned on.

ble operating pressure is not exceeded.

res that the appliance is not switched on inadver-
tently.

Operation

Preparation
• Connect a supply hose (not included) to
the water inlet of the unit and to the water supply
(e.g. water tap).
• Open the water supply.
The operation of the high-pressure cleaner with
!
a closed water supply line causes damage to the
cylinder head unit. Please never operate the high-
pressure cleaner with a closed water supply tap.
• Insert the mains plug.
• Turn master switch to "1/ON".
Owing to the water jet emerging from the high-
!
pressure nozzle a recoil force operates on the
handgun. Ensure you have a secure footing and
hold the handgun and spray lance firmly.
Switching on
• Press safety button on the handgun and pull the
lever.
Switching off
• Release the lever.
During breaks in work and when leaving the unit
secure it against inadvertent switching on by pres-
sing the safety button.
Adding the cleaning agent
• Remove spray lance
No detergent in high-pressure mode
• Suspend the filter of the detergent suction hose
in detergent reservoir.
• After cleaning agent has been added: Suspend
the filter of the detergent suction hose in
a container of clear water, switch on the unit for
about one minute and flush through.
Recommended cleaning method
1. Spray the cleaning agent on the dry surface spa-
ringly and let it react (but not dry out).
2. Wash off the loosened dirt with the high-pressure
jet.
Connect accessories
• Exchange the respective accessory with the
spray lance.
Depending on the model the following accessories
are either included in the scope of delivery or are
obtainable from specialist dealers (see also "Spe-
cial accessories").
