Before performing any routine or extraordinary maintenance operation, proceed as follows:
1. Take the machine to the maintenance area.
N.B.: the place designated for this operation must comply with current regulations concerning safety at work and current environmental
protection regulations.
2. Carry out the steps required to secure the machine; see paragraph "MACHINE SAFETY" on page 15.
CAUTION: it is recommended to wear the appropriate PPE (Personal Protective Equipment), suitable for the work to be carried out.

REPLACING THE SQUEEGEE BODY RUBBER BLADES

The good condition of the rubber blades in the squeegee body guarantees better floor drying results, as well as a longer service life for the suction
motor.
1. Stand at the back of the machine.
2. Remove the vacuum hose (1) from the sleeve in the vacuum nozzle (2) (Fig.1).
3. Unscrew the knobs (3) in the squeegee body pre-assembly (Fig.2).
4. Remove the squeegee body from the slits in the squeegee connector.
Proceed as follows for replacing the front rubber blade of the squeegee body:
5. Turn the wing nuts (5) into the horizontal position (Fig.3) and remove the front rubber blade compression plates (6) (Fig.4).
6. Remove the worn front rubber blade and replace it with the new one.
7. Repeat the operations in reverse order to reassemble all the parts.
Proceed as follows for replacing the rear rubber blade of the squeegee body:
8. Turn the wing nuts (7) into the horizontal position (Fig.5) and remove the front rubber blade compression plates (8) (Fig.6).
9. Remove the worn front rubber blade and replace it with the new one.
10. Repeat the operations in reverse order to reassemble all the parts.
N.B.: Before starting to work again, adjust the squeegee body - see "ADJUSTING THE SQUEEGEE BODY'S RUBBER BLADES" on page
36.

REPLACING THE BRUSH HEAD BODY BRUSHES

The good condition of the brushes in the brush head body guarantees better floor cleaning results, as well as a longer service life for the
gearmotors in the brush head body.
To replace the brushes in the manual machine version, proceed as follows:
1. Stand on the left side of the machine.
2. Turn the brush in increments so that the button on it is released from the coupling spring in the brush-holder plate (Fig.7).
N.B.: Image 7 indicates the direction of rotation for coupling the left brush; the right brush must be turned in the opposite direction.
