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.
DRAINING THE RECOVERY TANK
Proceed as follows to empty the recovery tank:
1. Release the recovery tank drainage tube (on the back of the machine) from the retainers (Fig.1).
2. Bend the end of the drainage tube in order to create a choke and prevent the content from coming out (Fig.2), then position the tube on the
discharge surface, unscrew the cap, and gradually release the tube.
3. Repeat the operations in reverse order to reassemble all the parts.
CLEANING THE SQUEEGEE BODY
The careful cleaning of the whole vacuum unit ensures better drying and cleaning of the floor as well as a longer suction motor life.
To carry out the cleaning of the squeegee body, proceed as follows:
1. Stand at the back of the machine.
2. Remove the vacuum hose (1) from the sleeve in the vacuum nozzle (2) (Fig.3).
3. Unscrew the knobs (3) in the squeegee body pre-assembly (Fig.4).
4. Remove the squeegee body from the slits in the squeegee connector.
5. Use a jet of water and then a damp cloth to thoroughly clean the vacuum chamber (4) of the squeegee body (Fig.5).
6. Use a jet of water and then a damp cloth to thoroughly clean the front rubber blade (5) of the squeegee body (Fig.6).
7. Check the state of wear of the front rubber blade (5) of the squeegee body, replacing it if the corner of the blade that comes into contact with
the floor is damaged - see "REPLACING THE SQUEEGEE BODY RUBBER BLADES" on page 34.
8. Use a jet of water and then a damp cloth to thoroughly clean the rear rubber blade (6) of the squeegee body (Fig.7).
9. Check the state of wear of the rear rubber blade (6) of the squeegee body, replacing it if the corner of the blade that comes into contact with
the floor is damaged - see "REPLACING THE SQUEEGEE BODY RUBBER BLADES" on page 34 (bear in mind that the blade can be
rotated on its four corners).
10. Unscrew the knobs (7) that fix the vacuum nozzle (2) to the squeegee body (Fig.8).
11. First with a jet of water and then with a damp cloth, thoroughly clean the vacuum nozzle (2). Also clean the squeegee body support surface.
12. Repeat the operations in reverse order to reassemble all the parts.
CLEANING THE RECOVERY TANK FILTER-FLOAT
Careful cleaning of the recovery tank filter-float guarantees better cleaning of the floor as well as a longer suction motor lifespan.
Proceed as follows to clean the recovery tank filter-float:
1. Grip the handle on the back of the recovery tank cover and remove it (8) (Fig.9).
2. Unscrew the floating cover (9) (Fig.10).
3. Remove the vacuum filter (10) and clean it (Fig.11).
N.B.: you are advised to use a jet of air to remove the impurities before cleaning the filter. Position the filter at least 20cm from the air jet.
ATTENTION: do not use highly corrosive products to clean the filter, to avoid damaging it.
4. Unscrew the upper body of the float (11) (Fig.12).
N.B.: when removing the upper part of the float, be very careful not to remove the lower part as well (12) (Fig.12).
5. Remove the float (13) (Fig.13). Rinse the inside with a jet of water. If necessary, use a spatula to remove the sludge that has accumulated at
the bottom of the float.
N.B.: If the polyurethane ring on the float body (Fig.13) is excessively worn or damage contact the nearest service centre.
6. Repeat the operations in reverse order to reassemble all the parts and move on the second float filter.
