tomer service.
Danger
Turn off the appliance and remove the mains
plug prior to any care and maintenance work.
Repair works may only be performed by the

Check whether the voltage indicated on
the type plate corresponds to the voltage
of the mains supply.

Appliance ventilation: Switch the appli-
ance on with the high-pressure hose de-

tion without bubbles. Switch off appliance
and reconnect high-pressure hose.
Check the water supply.
Pull out the sieve in the water connection
using flat-nose pliers and clean under run-
ning water.

the trigger gun and then switch the appli-
ance switch to "I/ON".

and debris from the nozzle bore, using a
needle and rinse through with water from
the front.

Slight leakage from the appliance pump is
normal. If the leakage increases contact
