pressure (MIN).
Î
Set thermostat to max. 95 °C.
Î
Set the operating pressure on the pump
unit to the maximum value.
Î

Danger
When adjusting the pressure/quantity regu-
lation, make sure that the screw connection
of the spray lance does not become loose.
Note:
For long term work with low pres-
sure, set pressure at the pump unit.
–
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.
–
Loosen the dirt:
Î
Spray detergent economically and let it
