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