Check/Remove brush head for foreign
matter
When foreign matter is on the brush roller this
can influence the cleaning result.
– Remove all foreign matter.
Splashguard
The side splashguard (2) must lie on the floor
when the brush head (1) is lowered, so that water
cannot escape from the side.
Adjust brush head
– Move the unit onto a level floor.
– Lower the brush head in the test-mode.
– Loosen the brush head fastening bolts on both
sides of the oblong hole (5) (stop nut (3) and
fastening nut (8)).
– Allow the brush head to run in the test mode.
By doing so the brush head will align itself to
the floor surface.
– While running the brushes first tighten the fa-
stening nut (8) with the fastening bolt (7) in the
oblong hole (5).
– Now tighten the stop nut (3) enough so there
is approx. 1 mm (0.039 in) play at the bracket
(4).
– Raise the brush head in the test-mode.
