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 device.
See Figure 6.
–
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.
0 = work without detergent
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.
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

0° full ray - nozzle
–
For sensitive surfaces and light contam-
inations
