16. Repeat the operations in reverse order to reassemble all the parts.
CLEANING THE DISC BRUSHES
Careful cleaning of the disc brush guarantees better cleaning of the floor as well as a longer brush
motor life.
To clean the disc brush, proceed as follows:
1. Select the i-drive program “transport” by rotating the knob to position “A” as shown in ( Fig.1 ).
N.B. : by rotating the i-drive selector to the transfer program, all the brush heads and the squeegee
body will move to their idle positions (raised off floor).
N.B. : on the screen of the command display, the machine silhouette will have a green icon only
the symbol that identifies the traction motor.
2. Take the machine to the maintenance area.
NOTE
: the place designated for this operation must comply with current environmental protection
regulations.
3. Engage the parking brake by moving the parking brake lever (2) (at the side of the operator seat)
in the direction shown by the arrow ( Fig.2 ).
N.B. : the symbol regarding the parking brake being engaged will appear on the command
display.
4. Select the “scrubbing” program (E) ( Fig.3 ), turn the i-drive adjustment switch (3) in the direction
indicated by the arrow ( Fig.4 ).
5. Press the drive pedal (4) to bring the scrubbing brush heads to the working position ( Fig.5 ).
N.B. : on the command display the symbols for the traction motor and the disc brushes motors
will be green.
6. As soon as the scrubbing brush heads are in the working position, make sure the machine is in a
safe condition (read “ MACHINE SAFETY ”).
7. Remove the right brush head, unscrew the knobs (5) and shift them outward ( Fig.6 ).
8. Place the brush head body on the ground with the brush holding plates in view ( Fig.7 ).
9. Turn until the brush so that the button is pushed towards the outside of the coupling spring.
N.B. : the photo ( Fig.8 ) shows the rotation directions for removing the right scrubbing brush
head brushes, for the left brush the rotation direction is the opposite.
10. Clean the brushes under a jet of water and remove any dirt in the brush bristles. Check the bristles. If
they are excessively worn, replace the brushes (the bristles should protrude by at least 10mm). Read
the paragraph “ OREPLACING DISC BRUSHES ” for replacing the brushes.
11. Repeat the operations in reverse order to reassemble all the parts.
N.B. : you are advised to invert the right and left-hand brushes every day. If the brushes are
not new however, and have deformed bristles, it is better to reassemble them in the
same position (the right-hand one on the right, and the left-hand one on the left), to prevent
the different inclination of the bristles producing an overload on the brush motor as well as
excessive vibrations.
CLEANING CYLINDRICAL BRUSH
Careful cleaning of the cylindrical brush guarantees better cleaning of the floor as well as a longer life
for the brush motor.
To clean the cylindrical brush, proceed as follows:
1. Select the i-drive program “transport” by rotating the knob to position “A” as shown in (
Fig.1
).
N.B. : by rotating the i-drive selector to the transfer program, all the brush heads and the squeegee
body will move to their idle positions (raised off floor).
N.B. : on the screen of the command display, the machine silhouette will have a green icon only
the symbol that identifies the traction motor.
2. Take the machine to the maintenance area.
NOTE : the place designated for this operation must comply with current environmental protection
regulations.
3. Shift the direction lever (1) to “idle”, moving it in the direction shown by the arrow ( Fig.2 ).
N.B. : to select idle (N) move the lever in the direction shown by the arrow ( Fig.2 ).
N.B. : the letter “N” will appear on the command display indicating that no gear is engaged.
4. Engage the parking brake by moving the parking brake lever (2), beside the operator's seat, in the
direction shown by the arrow (
Fig.3
).
N.B. : the symbol for the parking brake being engaged will appear on the command display.
5. Select the i-drive program “scrubbing with drying” by rotating the knob to position “C” as shown in
( Fig.1 ).
N.B. : rotating the i-drive selector to the scrubbing with drying program, all the brush heads and
squeegee body will move to their working positions (in contact with the floor).
6. Press the drive pedal (3) to move both the squeegee body and the brush head bodies to their
working positions ( Fig.4 ).
N.B. : on the screen of the command display, the machine silhouette will have a green icon.
the symbol that identifies the traction motor; the symbols that identify the motors of the
scrubbing brush head; the symbols that identify the motor of the sweeping brush head; the
symbols that identify the vacuum motors.
7. As soon as the brush head and splash guard bars are in the working position, make sure the
machine is in a safe condition (read “ MACHINE SAFETY ”).
CAUTION : these operations must be carried out using protective gloves to avoid any possible
contact with the edges or tips of metal objects.
8. Stand on the right side of the machine.
9. Remove the retainer (4) from the pin (5) in the squeegee body ( Fig.5 ).
10. Free the pin (5) in the squeegee body from the eyelet (6) in the squeegee control bar ( Fig.6 ).
11. Turn the right splash guard bar (7) as far as it will go.
12. Remove the casing cover of the cylindrical control brush arm (8), to do this you first need to remove
the retainer knobs (9) from the machine. To remove the knobs (9) turn them in the direction shown
by the arrow ( Fig.7 ).
13. Remove the cylindrical control brush arm (10), to do this you first need to remove the retainer knob
(11). To remove the knob (11) turn it in the direction shown by the arrow ( Fig.8 ).
14. Extract the brush from the machine.
15. Clean the brush under a stream of running water to remove any impurities from its bristles. Check
that the bristles are not worn; in the event of excessive wear, replace the brush (the bristles should
be at least 10 mm long).
ATTENTION : for replacing the cylindrical brush, read the section “ REPLACING THE
CYLINDRICAL BRUSH ”.
16. Insert the new brush in the brush head tunnel, making sure that the pins (12) in the traction hub (13)
enter the slots (14) in the brush ( Fig.9 ).
