6.3.1
Brush Deck
The brush deck must be free to lean
evenly to the ground and properly carry
out its function. Check that the tunnel
cover engages properly in the side rein-
forcement to allow a good coupling be-
tween brush and joint.

Brush coupling Shaft
Check
(to perform every
150h
)
As the other components, it is important
that the brush coupling shaft is in good
condition and clean to allow a good
coupling with the brush. If necessary,
replace it
(see section
at page
.
6.3.3
Bearings
Check
(to perform every
150h

The bearings allow a fluid rotational
movement of the motor. To prevent the
brush to get stuck, is important that
the bearings are in good condition and
clean.
In case of excessive wear it is necessary
to proceed with the replacement.
