4. Lubricating-disengageable

clutch, reduction gear

Optional equipment, TAMD70D.

Lubricate the throw-out bearing (nipple 1) daily, before
starting.
NOTE! Lubricate sparingly, to avoid risk of excess grease
finding its way onto the dry clutch linings and causing slip.

Use multi-purpose heat resistant grease.

5. Checking oil level in reduction

gear

Optional equipment, TAMD70D

Check the level daily before starting.

The oil should be filled up to the level plug (7). Top-up with
oil if required. Regarding oil quality and viscosity, see table
below. Concerning oil changing, see page 28.
