5.9.3 Adjusting the sealing strips
Angle adjustment
The angle adjustment is the decisive
factor in ensuring the squeegee's seal-
ing strips lie evenly on the floor.
1. Park the machine on a level surface
and lower the squeegee.
2. Loosen the counternut on the screw
(Fig. 28/3) and use the counternut to
adjust the squeegee so that the ends
of the sealing strips just make con-
tact with the floor.
Fig. A
Turn the counternut counterclock-
wise: Distance from sealing strip to
floor is reduced in the middle.
Fig. B
Turn the counternut clockwise: Dis-
tance from sealing strip to floor is in-
creased in the middle.
3. Switch the vehicle on and check the
suction pattern. While driving, the
sealing strips must make an overall,
even contact with the floor (in the
center and at both ends).
4. Tighten the counternut of the adjust-
ing bolt at 7 Nm.
