 Turn the regulation spindle in a clock-
wise direction: Increase working pres-
sure (MAX).
 Turn the regulation spindle in an anti-
clockwise direction: Reduce working
pressure (MIN).
– For considerate treatment of the envi-
ronment use detergent economically.
– The detergent must be suitable for the
surface to be cleaned.
 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.
Note: If detergent is be suctioned from an
external container, route the detergent suc-
tion hose through the recess to the outside.
 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.
– 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.
Removal of light contaminations and clear
rinse, i.e.: Gardening tools, terrace, tools,
etc.
 Set operating pressure according to
need.
The appliance works in the most economi-
cal temperature range (max. 60 °C).
We recommend the following cleaning tem-
peratures:
– Light contaminations
30-50 °C
– Contaminations containing protein, i.e.
in the food processing industry
max. 60 °C
– Vehicle cleaning, machine cleaning
60-90 °C
– De-preserve, contaminations contain-
ing strong fat contents
100-110 °C
– De-frosting of surcharge substances,
partially facade cleaning
up to 140 °C
 DANGER
Scalding danger!
 Set device switch to desired tempera-
ture.
 DANGER
Scalding danger! The work pressure must
not exceed 3.2 MPa (32 bar) when operat-
ing with temperatures above 98 °C.
Therefore the following measures must
definitely be performed:

 Replace high pressure nozzle (stain-
less steel) with steam nozzle (brass,
order see specification).
 Set the working pressure/quantity regu-
lation at the pump unit to the minimum
quantity.
 Set device switch to min. 100 °C.
 Secure the trigger gun. To do so, push
the safety catch towards the front.
