ASSEMBLING THE SPLASH GUARD RUBBERS (BASES WITH DISC BRUSHES)

For packaging reasons, the splash guard rubbers are supplied disassembled from the machine. To
connect the rubber, remove the rubber-pressing blades and unthread the spring hook (1) from the
connection screw. Wind the rubber all around the base, inserting the base fixing screw in the central
hole. Reattach the blades, starting from the centre of the base.
Be careful not to invert the right blade with the left one, as they are not the same.

23. ASSEMBLING THE BRUSH (BASES WITH DOUBLE DISC BRUSH)

Proceed as follows to assemble the brushes:
1. Use the parking brake handle (1) to stop the machine. Unthread the pin (3) from its seat on the
handlebars, and insert it in the holes of the handle (2) to prevent the lever slipping.
2. Raise the base by means of the appropriate pedal
3. Check that the key is in the "0" position (2)
4. With the base up, place the brushes into the plate housing beneath the base, turning the brushes
until the three pins enter the niches in the plate itself; turn until the pin is pushed towards the
coupling spring and is locked into place.
The figure shows the rotation direction for coupling the right-hand brush; for the left-hand one, rotate in
the opposite direction.
ATTENTION: during this operation, check there are no people or objects near the
brush.
ATTENTION: Make sure the brushes are correctly connected. If this is not the
case, the machine could move in an irregular, sudden manner.
ATTENTION: you are advised to always wear protective gloves, to avoid the risk
of serious injury to your hands
5. 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.

24. ASSEMBLING THE BRUSH (BASES WITH CYLINDRICAL BRUSHES) MX 50S

Proceed as follows to assemble the brushes:
1. Use the parking brake handle to stop the machine. Unthread the pin from its seat on the
handlebars, and insert it in the holes of the handle to prevent the lever from slipping.
2. Make sure that the key switch is in the "0" position
3. Raise the base by means of the appropriate pedal
4. Loosen the wing nut (1)
5. Rotate the side splash guard (2).
6. Remove the splash guard (3)
7. Remove the idle hubs
