DANGER
Risk of personal injury or damage! Never suck in water
from a drinking water container. Never suck in liquids
which contain solvents like lacquer thinner, petrol, oil or
unfiltered water. The sealings within the device are not
solvent resistant. The spray mist of solvents is highly in-
flammable, explosive and poisonous.
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.
DANGER
Danger of explosion! Do not spray flammable liquids.
DANGER
Risk of injury! Never use the appliance without the spray
lance attached. Check and ensure proper fitting of the

Note: If the indicator lamps for pump, rotation direction,
burner malfunction or engine are on during operation,
turn off the appliance immediately and repair malfunc-
tion, refer to "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-
es back on.
Note: If no water comes out of the high pressure nozzle,
vent pump. Refer to "Help with malfunctions - appliance
is not building up pressure".
Adjust cleaning temperature
 Set temperature regulator to desired temperature.
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).
Pressure/ quantity regulation at the hand spray gun
 Set thermostat to max. 98 °C.
 Set the working pressure/quantity regulation at the
pump unit to maximum quantity.
 Set the working pressure and feed quantity by turn-
ing (steplessly) the pressure/quantity regulation
mechanism at the hand spray gun (+/-).
DANGER
Risk of injury! When adjusting the pressure/quantity
regulation, make sure that the screw connection of the
spray lance does not become loose.
Note: For long term work with low pressure, set pressure
at the pressure/quantity regulation of the pump unit.
Operation with detergent
