Mounting and adjusting the squeegee

The squeegee (fig. 6) is responsible for the first phase of drying.
To mount the squeegee on the machine, proceed as follows:
•
check that the squeegee mount (fig. 6, ref. 2) is raised, otherwise lift it by means of the
squeegee lever (fig. 5, ref. 8);
•
insert the suction hose sleeve (fig. 6, ref. 4) fully into the squeegee;
•
slacken the two knobs (fig. 6, ref. 3) at the centre of the squeegee;
•
insert the two threaded pins into the slots on the support (fig. 6, ref. 2);
•
fix the squeegee by tightening the two knobs (fig. 6, ref. 3).
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. The
angle of the blades can be adjusted using the screw (fig. 6, ref. 1), while the height of the
squeegee from the floor can be adjusted using the screw (fig. 6, ref. 5).
6.3.

Moving the machine when not in operation

Proceed as follows to move the machine.
•
raise the squeegee;
•
push the head pedal down then to the right (fig. 5 ref. 9) to raise the head;
•
move the machine as follows:
• Versions with mechanical drive: push or pull;
• Versions with electric drive: to move the machine forwards, press the selector
(fig. 5 ref. 13), then operate the drive lever (fig. 5 ref. 7). To move the machine
backwards, press the selector (fig. 5 ref. 13), then operate the drive lever (fig. 5.
ref. 7);
speed can be varied by the potentiometer knob (fig. 5. ref. 11).
•
once you have reached your destination, lower the head by pressing the release pedal
(fig. 5 ref. 9) down and to the left, then release it.
Do not leave the machine unattended or parked with the head lifted or the key

Mounting and changing the brush/drive disks

6.4.
Never work without the brushes, rollers and drive disks perfectly installed.
Fitting the brush (one-brush models): Rest the brush on the floor in front of the
machine and centre it with the guard. Lower the head and repeatedly action the
brush/drive control lever (fig. 5, ref. 7) until the brush automatically engages on the flange
hub. If the manoeuvre is not successful, press on the handle again and repeat the
centring and repeated actioning of the brush/drive lever.
Use of abrasive/microfibre disks: fit the abrasive/microfibre disk on the drive disk and
perform the operations described for fitting the brush on the scrubber drier.
Removing the brush (one-brush models) (or drive disk):
Raise the machine head by pushing the head lift pedal down and then to the right (fig. 5,
