7. Mechanical components
7.1 Squeegee
Adjusting the sealing strips / inclination
The inclination adjustment decides whether the sealing strips of the squeegee are
positioned evenly on the ground.
1. Place the machine on a level surface and lower the squeegee.
2. Loosen the lock nuts of the threaded bar (Fig. 7.2.a – A) and use the threaded bar
(Fig. 7.2.a – B) to adjust the squeegee ensuring the ends of the sealing strips barely
have contact with the ground.
Turn the threaded bar anti-clockwise: The distance of the sealing strip to the ground
increases in the middle. (Fig. 7.2a)
Turn the threaded bar clockwise: The distance of the sealing strip to the ground
decreases in the middle. (Fig. 7.2.b)
3. Turn on the machine and check the suction pattern. When driving, the sealing strips
must be turned over evenly everywhere (centre and outside).
4. Tighten the lock nut of the adjusting screw to 7 Nm.
