EVERY 50 HOURS

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.
