MAINTENANCE
EVERY 50 HOURS
Perform routine checks : Refer - DAILY BEFORE USE.
Check cutterhead roller bearing adjustment:
Important: Prevent Damage - It is essential that the cutter-
head roller bearings are kept in good adjustment in order to
ensure maximum working life. If roller end float is allowed
to become excessive premature bearing failure will result.
Grip the roller and move from side to side and up and
down. If excessive movement is detected proceed as follows:
Carefully tighten nuts ‘A’ at each end of the roller with the
spanner provided, just sufficiently to remove any end float.
Note: The roller should still rotate freely after adjustment.
Overtightening of nuts ‘A’ could lead to premature bearing
failure.
Check cutterhead rear roller scraper wire tension:
It is important that the scraper wires are correctly tensioned so
as to ensure correct operation and maximum working life.
Carefully tighten the scraper wire retaining nuts ‘B’ so as to just
remove any slack from the scraper wires then tighten nuts ‘B’ a
further four full turns to correctly tension the wire.
IMPORTANT: PREVENT DAMAGE - Do not over tighten
the scraper wires.
Check wheel nut torque settings:
Front axle wheel nut torque setting - 200Nm (148 Ibf.ft).
Rear axle wheel nut torque setting - 54 Nm (40 Ibf.ft).
Greasing the transmission control unit:
It is important to grease the transmission control unit. This is
done using the remote grease nipple located adjacent to the
hydraulics oil tank filler.
Pump grease into the unit until it can be seen exuding from both
ends of the control unit.
