REPLACING THE SCRUBBING BRUSH HEAD BODY BRUSHES
If the scrubbing brush head brushes are damaged they cannot work properly, or more specifically, they cannot remove the dirt from the floor; as
such, the condition of these must be checked. To replace the scrubbing brush head brushes, proceed as follows
1. Go to the left hand side of the machine, and with the brush head raised up from the floor, remove the side splash guard casing from the brush
head ( Fig.2 ).
N.B. : before removing the splash guard casing, turn the fixing anchors (1) on the brush head body to the maintenance position ( Fig.1 ).
2. Press the brush locking pin (2) ( Fig.3 ).
3. Keeping the pin (2) pressed, turn the brush clockwise until it is released ( Fig.4 ).
4. Turn until the button is pushed towards the outside of the coupling spring and is locked into place.
5. Check the wear status of the bristles and replace the brushes if they are excessively consumed (the bristles' protrusion must not be less than
10 mm; this distance is indicated on the brush by the yellow band). For replacing the brushes, refer to “ FITTING THE SCRUBBING BRUSH
HEAD BRUSHES ”.
6. After checking to make sure that the brush is clean, reassemble it and move on to the one on the right hand side.
N.B. : The image in Fig.4 indicates the direction of rotation for uncoupling the left brush; the right brush must be turned in the opposite
direction.
7. Proceed in the opposite order to reassemble all the parts.

ADJUSTMENT INTERVENTIONS
ADJUSTING THE SQUEEGEE BODY'S RUBBER BLADES
The careful adjustment of the squeegee body rubber blades guarantees better cleaning of the floor.
To adjust the squeegee body blades, proceed as follows:
1. Sit on the driver’s seat.
2. Insert the key (1) into the main switch on the control panel. Set the main switch to "I" ( Fig.1 ).
3. Using the knob (2) on the control panel ( Fig.2 ), select the “SCRUBBING WITH DRYING” work program.
4. Press the drive pedal (3) (
Fig.3
) to begin moving the machine.
5. As soon as the brush head and the squeegee have reached their working positions, perform the procedure for securing the machine (see the
chapter “ MACHINE SAFETY MEASURES” ).
CAUTION : it is recommended to wear the appropriate PPE (Personal Protective Equipment) for the work to be carried out.
6. Stand at the back of the machine.
Adjusting the height of the squeegee body:
7. Release the stopper lever (3) for the squeegee's height adjustment knob (4) ( Fig.3 ).
8. Adjust the height of the rubber blade in relation to the floor by loosening or tightening the knobs (4) ( Fig.4 ).
N.B. : Figure 4 indicates the rotation direction for decreasing the distance between the squeegee support and the floor. This distance can be
increased by turning it in the opposite direction.
N.B.
: By decreasing the distance between the squeegee support and the floor, the rubber blades present in the squeegee body move closer
to the floor.
N.B. : The right-hand and left-hand knobs must be rotated the same number of times, so that the squeegee is parallel to the floor when it is
working.
N.B. : Make sure the adjustment is correct by looking at the instrument (5) on the squeegee body ( Fig.5 ).
