Perform routine checks : Refer - DAILY BEFORE USE.
Check cutterhead roller bearing adjustment:
IMPORTANT : PREVENT DAMAGE - It is essential that
the cutterhead roller bearings are kept in good adjustment
in order to ensure maximum working life. If 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 fol-
lows:
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 and then tighten nuts
‘B’ a further four full turns to correctly tension the wires.
IMPORTANT: PREVENT DAMAGE - Do not over tighten
the scraper wires.
Check wheel nut torque settings:
Front axle wheel nut torque setting - 200Nm.
Rear axle wheel nut torque setting - 54 Nm.
