Power connection
– For connection values, see technical data and type
plate.
– The electrical connections must be done by an
electrician according to IEC 60364-1.
DANGER
Risk of injury on account of electric shock!
– Unsuitable electrical extension cables can be haz-
ardous. Only use electrical extension cables out-
doors which have been approved and labelled for
this purpose and have an adequate cable cross-
section.
– Always unwind extension lines completely.
– The plug and coupling of the extension cable used
must be watertight.
ATTENTION
The highest allowed net impedance at the electrical
connection point (refer to technical data) is not to be ex-
ceeded. In case of confusion regarding the power im-
pedance present on your connection, please contact
your utilities provider.

catch towards the front.
 Replacing the nozzle.
Turning on the Appliance
 Set appliance switch to desired operating mode.
Indicator lamp for operational readiness lights up.
The device starts briefly and turns off, as soon as the
working pressure is reached.
Note: If the control lamp "rotation direction" lights up,
please switch the appliance off immediately and fix the
error, see "Help with malfunctions".
 Release the trigger gun. To do so, push the safety
catch towards the back.
When activating the hand spray gun the device switch-

30 °C to 98 °C
– Clean with hot water.
100 °C to 150 °C
– Clean using steam.
 In steam operation (> 100°C), use the steam noz-
zle available as an accessory (see "Steam opera-
tion").
Set working pressure and flow rate
Pressure/quantity regulation of the pump unit
 Turn the regulation spindle in a clockwise direction:
Increase working pressure (MAX).
 Turn the regulation spindle in an anti-clockwise di-
rection: Reduce working pressure (MIN).
Operation with detergent
– For considerate treatment of the environment use
detergent economically.
– The detergent must be suitable for the surface to
be cleaned.
 With support of the detergent dose valve set deter-
gent concentration as determined by the manufac-
turer.
Note: Recommended values at the control panel at
maximum working pressure.
Note: If detergent is be suctioned from an external con-
tainer, route the detergent suction hose through the re-
cess to the outside.
 Set pressure/temperature and detergent concen-
tration according to the surface to be cleaned.
Note: To prevent damage due to too much pressure, al-
ways position high pressure ray first from a greater dis-
tance towards object to be cleaned.
Recommended cleaning method
– Loosen the dirt:
 Spray detergent economically and let it work for
1...5 minutes but do not let it dry up.
– Remove the dirt:
 Spray off loosened dirt with the high pressure jet.
