1. Park the machine on a level surface and lower

the squeegee.

2. Loosen the lower wing nut (B) on the adjust-

ing screw (A) 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 (A) coun-

terclockwise, the clearance between squeegee

blade and floor is increased in the center (Fig.

1). When turning the adjusting screw (A) clock-

wise, the clearance between squeegee blade

and floor is reduced 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.
