at "0" position because otherwise the burn-
er will switch off.
The device starts briefly and turns off, as
soon as the working pressure is reached.
Note:
If the control lamps fuel, liquid soften-
er or motor light up, please switch the appli-

Release the hand spray gun (A).
When activating the hand spray gun the de-
vice switches 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".
Î
Set temperature regulator to desired
temperature.
30 °C to 80 °C:
–
Clean with hot water.

Î
Turn the regulation spindle in a clock-
wise direction: Increase working pres-
sure (MAX).
Î
Turn the regulation spindle in an anti-
clockwise direction: Reduce working
pressure (MIN).
Note:
For long term work with low pres-
sure, set pressure at device.
–
For considerate treatment of the envi-
ronment use detergent economically.
–
The detergent must be suitable for the
surface to be cleaned.
Î
With support of the detergent dose
valve set detergent concentration as
determined by the manufacturer.
Note:
Recommended values at the control
panel at maximum working pressure.
Î
set pressure/temperature and deter-
gent concentration according to the sur-
face to be cleaned.
Note:
To prevent damage due to too much
pressure, always position high pressure ray
first from a greater distance towards object
to be cleaned.
The spray angle is essential for the effec-
tiveness of the high pressure ray. Normally
work is performed with a 25° flat ray nozzle
(included).
Recommended nozzles are deliverable as
accessories
–
For strong contaminations
0° full ray - nozzle
–
For sensitive surfaces and light contam-
inations
40° flat ray - nozzle
–
For thick layered, persistent contaminations
Dirt grinder
–
Nozzle with adjustable spray angle, for
adaption to different cleaning tasks
Angle-Vario-Nozzle
–
Loosen the dirt:
Î
Spray detergent economically and let it
work for 1...5 minutes but do not let it
dry up.
–
Remove the dirt:
Î
Spray off loosened dirt with the high-
pressure jet.
Removal of light contaminations and clear
rinse, i.e.: Gardening tools, terrace, tools, etc.
Î
Set operating pressure according to
need.
Î
Set temperature regulator to “0”.
