5.8.3 Adjusting the Blades Angle Adjustment
The angle adjustment is the decisive factor
in ensuring that the squeegee blades on the
squeegee lie evenly on the fl oor.
1. Park the machine on a level surface and
lower the squeegee.
2. Loosen the counternut on the adjusting
screw (Fig. 12/1) and adjust the squeegee
using the adjusting screw so that the ends
of the squeegee blades have contact with
the fl oor.
Figure A:
Turn the adjusting screw counter-
clockwise: The clearance between
squeegee blade and fl oor is reduced in the
center.
Figure B:
Turn the screw clockwise: The clearance
between squeegee blade and fl oor is
increased in the center.
3. Switch the machine on and check the
suction pattern. When the machi-ne is in
operation, the entire surface of the sealing
strips (center and outer areas) must be
applied as evenly as possible.
4. Tighten the counternut on the adjusting
screw at 5 lb ft.
