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.
