Adjusting the Squeegee Blades
Angle 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 lower wing nut (B) on the adjust­ing screw (C) and adjust the squeegee using
the adjusting screw so that the ends of the
squeegee blades still have contact with the
floor. By turning the adjusting screw (C) coun­terclockwise, the clearance between squeegee
blade and floor is increased in the center (Fig.

1). When turning the adjusting screw (C) clock­wise, the clearance between squeegee blade
and floor is redused in the center (Fig. 2).

3. Switch the machine on and check the suction
pattern. When the machine is in operation, the
entire surface of the squeegee blades (center
and outer areas) must be applied as evenly as
possible.

4. Tighten the lower wing nut (B) on the adjust­ing screw (C) against the metal bracket to lock
in the pitch setting.

Adjusting the Squeegee Blades
Height Adjustment

If streaks are present, despite an optimum
angle adjustment, the clearance between the
caster wheels and floor must be adjusted by
changing the number of washers underneath
the bracket that holds the wheel. The
squeegee height is preset at the factory to
3mm.

In cases of very smooth floors, e.g. finished
floors, PVC, linoleum, etc., see 2mm
illustration for washer configuration.
