Adjusting the sealing strips
Inclination adjustment
The correct inclination adjustment is decisive for:
• ensuring that the sealing strips of the squeegee rest evenly with the
complete contact surface on the ground
• ensuring that the squeegee runs smoothly and evenly during the suction
process.
1. Place the machine on a level surface and lower the squeegee.
2. Loosen the lock nuts

and turn the threaded bar
Fig. 46-B
to
adjust the squeegee ensuring both ends of the sealing strips barely have
contact with the ground.
• Turn the threaded bar counter-clockwise: The distance of the sealing
strip to the ground increases at the ends

.
• Turn the threaded bar clockwise: The distance of the sealing strip to the
ground decreases at the ends

.
3. Turn on the machine and check the suction pattern. When driving, the
sealing strips must be turn over evenly everywhere (centre and outside).
4. Tighten the lock nuts of the threaded bar to 54 Nm.
