High-pressure cleaning
9.
Carefully set the spray angle by rotating the spray head of the lance (Fig. 28).
CAUTION:
To take care of the material, we recommend not
concentrating the jet of high pressure right from the start.
Instead begin with a wide angle and only concentrate the jet
if it does not damage the surface.
NOTE:
You can also influence the cleaning effect by adjusting the
distance to the surface to be cleaned. A distance of 25–50 cm is a good
guideline.
NOTE:
When adjusting the spray head, the spray angle quickly assumes
2&#+6'+3+5'"2&-$9@B -4#!#02',1#22',%r'%G:@n #*-5sG
You can now clean the dirty surface using the high-pressure jet.
NOTE:
As soon as you release the spray button, the pump stops
working and a jet of high pressure no longer comes out.
WARNING:
Danger of injury! Keep aware! Even when the pump
is not running, there is high pressure in the system. If you want
to end work, switch off the appliance and use up the remaining
pressure. Also observe the instructions under Chapter 4.10,
“After high-pressure cleaning“.
