MAINTENANCE
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
).
2. Take the machine to the maintenance area.
ATTENTION:
the place designated for this operation must
comply with current environmental protection regulations.
3. Make sure the machine is in a safe condition (read “
ATTENTION:
these operations must be carried out using
protective gloves to avoid any possible contact with the edges
or tips of metal objects.
4. Stand on the right side of the machine. Disconnect the side
splash guard vacuum tube (1) from the vacuum nozzle (2) on
the splash guard itself (
Fig.2
).
ATTENTION
: remember to loosen the screw clamp (3) on
the vacuum tube before inserting it in the nozzle (
Fig.2
).
ATTENTION:
the equipment to be used for this operation is
not supplied with the machine.
5. Remove the pins (4) that block the rotation pins (5) of the brush
head splash guard (
Fig.3
).
6. Use the relative handle (6) to remove the right-hand splash guard
pre-assembly (
Fig.4
).
7. Rotate the brush clockwise (
Fig.5
) until the three buttons come
out of the slots on the plate. Turn until the button is pushed
towards the outside of the coupling spring and is locked into
place.
ATTENTION:
the picture (
Fig.5
) shows the rotation direction
for releasing the right-hand brush. For the left-hand brush,
turn in the opposite direction.
8. 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 “
REPLACING THE BRUSH
” for info
on how to replace the brushes.
9.
When the right-hand brush has been fitted, reassemble all the
parts and then fit the left-hand one.
ATTENTION:
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.
