6.3.2 Brush Deck
Check
(to perform every
150h
)
The brush deck must be kept clean and
intact. A ruined deck may be danger-
ous to the machine and the operator that
uses it.
If necessary, replace it.
6.3.3 Brush coupling flange
Check
(to perform every 150h )
The brush coupling flange is of plas-
tic material and is not subject to par-
ticular wear.
Like the other compo-
nents its cleanliness is essential to al-
low the brush to engage and disengage
smoothly.
’It is also essential that the
brush locking spring has full function-
ality in order to keep the brush in the
correct position.
If necessary, replace
it.
6.3.3-8 50 BT
6.3.4 Brass bushings
Check
(to perform every
150h
)
The brass bushings allow a fluid and
little tiring rotational movement of the
base. To prevent the base is locked in a
position without the possibility of move-
ment, is important that the brass bush-
ings are in good condition and clean. In
case of excessive wear it is necessary to
proceed with the replacement.
Maintenance
(to perform every 900h )
Brass bushings replacement:
Procedure:
• Secure the machine.
• Remove the screws that secure the
base to the machine body.
• Remove the scrub deck from the ma-
chine.
• Remove the bushings and replace
them with new bushings.
• Proceed to the reverse operations to
reassemble it all, sprinkle the new
bushings with lubricating grease be-
fore mounting.
• Once the operation has been com-
pleted proceed with the scrub deck
adjustment.
6.3.5 Bumping Wheel
Check
(to perform every 150h )
The bumping wheel must be free to ro-
tate and its diameter must not be too
small due to wear. A bumping wheel in
poor condition can lead to cracking of
the brush base when working skimming
some obstacles (walls, shelving, etc).
If necessary, replace it.
