help of the following overview.
If in doubt, please consult the authorized cus-
tomer service.

plug prior to any care and maintenance work.
Repair works may only be performed by the
authorized customer service.

Pull on the lever of the trigger gun; the de-
vice will switch on.
Check whether the voltage indicated on
the type plate corresponds to the voltage
of the mains supply.
Check the mains connection cable for
damages.
Pressure does not build up in the appli-
ance
Check setting at the spray lance.
Remove air from appliance before operation.
Switch on the appliance without connec-
tion the HP hose (max. 2 minutes) and run
it until the water discharging from the HP

ance and reconnect HP hose.
Check the water supply.

debris from the nozzle bore, using a needle
and rinse through with water from the front.
Check water flow quantity.
Appliance is leaking
Slight leakage from the appliance pump is
normal. If the leakage increases contact
the authorized customer service.

(Vario Power).
Turn the spray lance to "Mix" position.
Check the settings at the dosage regula-
tor for detergent.
Check the detergent suction hose for
