5. Servicing and
Maintenance
Follow the safety instructions for
servicing and maintenance.
5.1 Servicing
Your machine has been designed and
constructed for maximum performance,
operational efficiency and operator
friendliness under a wide variety of operating
conditions.
Prior to delivery, your machine has been
checked at the factory and by your authorised
dealer to ensure that you receive a machine
in optimum condition.
To ensure trouble-free operation,
it is important that servicing and
maintenance work is performed at
the recommended intervals.
5.2 Cleaning
In order to ensure that the machine is
always in operating condition and to achieve
optimum performance, perform the cleaning
and servicing work at regular intervals.
Avoid cleaning the roll / disc bearings with
a high-pressure hose or a direct water jet.
The housing, screwed connections and ball
bearings are not watertight.
5. Servicing and Maintenance
Regularly examine hub caps,
seals and pivot bolts and all
tracking bolts for tightness and
effectiveness twice weekly or
every 50 working hours (whichever
is more frequent).
5.3 Disc Hub
Maintenance
Grease every disc hub until grease shows
from the seals according to the lubricating
intervals outlined on page 35.
Check disc hubs regularly for tightness.
Fig. 5.01: Checking Disc Bearing Adjustment
1 Ensure that the bearing seal is in the
correct orientation when replacing /
assembling components.
2 Ensure that the stub axle is free from
dirt and the nut and outer bearing can
easily slide on it.
3 Tighten the crown nut with a hand
spanner (a torque wrench is not
required) while turning the hub
clockwise until the bearing drags
slightly (you feel the hub turning
heavily). Some resistance will be due
to friction from the seal.
4 Turn back the crown nut to the next
locking position. Even if the tightening
of the nut has reached an exact fixing
position, turn it back.
5 Insert the retaining pin.
6 Try to shake/rock the outer edge of the
hub/spindle: play of 0.1 / 0.2mm will
not reduce the bearings’ life and, in
addition, prevents overheating. If the
adjustment is correct the hub should
turn freely with the only friction being
from the seal.
