Perform routine checks: Refer to DAILY BE-
FORE USE.
Check cutterhead roller bearing adjustment:
Important: Prevent Damage - It is essential that
the cutterhead roller bearings are kept in good
A
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
B
tensioned so as to ensure correct operation and
maximum working life. Carefully tighten the
scraper wire retaining nuts 'B' so as to just remove
B
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
lbf.ft).
Rear axle wheel nut torque setting - 54 Nm (40 lbf.
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.
