is free of bubbles. Switch off appliance
and reconnect high-pressure hose.
Check the water supply.
Pull out the sieve in the water connec-
tion using flat-nose pliers and clean un-
der running water.
Cause: Voltage reduction due to weak
mains supply or when using an extension
cable
.
When switching on, first pull the lever of
the hand spray gun and then switch the

ing a needle and rinse through with wa-
ter from the front.
Check water flow quantity.
Slight leakage from the appliance pump
is normal. If the leakage increases con-
tact the authorized customer service.
Use spray lance with pressure regula-
tion (Vario Power).
Turn the spray lance to "Mix" position.
