Mounting and adjusting the squeegee

The squeegee (fig. B, ref. 6) is responsible for the first phase of drying.
To mount the squeegee on the machine, proceed as follows:
1) insert the sleeve of the suction hose (fig. E, ref. 1) fully into the squeegee;
2) slacken the two knobs (fig. E, ref. 2) at the centre of the squeegee;
3) insert the two threaded pins into the slots on the support (fig. E, ref. 3)
4) fix the squeegee by tightening the two knobs (fig. E, ref. 2)
The squeegee blades scrape the film of water and detergent from the floor and prepare
the way for perfect drying. With time, the constant rubbing makes the edge of the blade in
contact with the floor rounded and cracked, reducing the drying efficiency and requiring it
to be replaced. The state of wear should be checked frequently.
For perfect drying, the squeegee must be adjusted in such a way that the edge of the rear
blade bends during operation by about 45° with respect to the floor at every point. Adjust
the angle of the blade during operation by regulating the height of the two wheels
positioned in front of/behind the squeegee.
