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.
 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.
 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:

