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.
In the case of hydraulic cylinders that have
been cleaned using high pressure equipment
ensure that all hydraulic circuits are functional
and pressurised fully in both directions. This
provides the necessary coating of oil onto
cylinder rods after cleaning.
5.3 Disc Hub Maintenance
5. Servicing and Maintenance
1. Grease every disc hub until grease
shows from the seals according to the
lubricating intervals outlined on page38.
2. Check disc hubs regularly for tightness.
3. Check main bearing adjustment (twin
taper roller) after 50 hours and thereafter
seasonally by ‘rocking’ the disc as per
Fig. 5.01. If play is evident then the
following procedure should be followed.
Loosen the small grubscrew locking the
bearing cap to the housing. Remove
bearing caps and locking pins, tighten
nuts to inhibit rotation before backing off
the nuts slightly until disc rotation is
enabled and play is eliminated (usually
between 1/6 - 1/12 of a turn). Re-fit the
locking pins. Fit and securely tighten
disc hub caps and flush with grease until
grease shows from seal area.
4. Regularly examine hub caps, seals,
shear and pivot bolts and all tracking
bolts for tightness and effectiveness
twice weekly or every 50 working hours
(whichever is more frequent).
