6.6.4 Chute worm gear
See fig. 13.
If the discharge chute is difficult to operate, first lubricate the
pinion gear (B) and ring gear (A). If it is still difficult to
operate, adjust as follows:
1. Loosen the nut (C), which holds the pinion gear bracket
in the slotted hole.
2. If the pinion gear is too tight against the ring gear, move
it away slightly and then retighten the nut.
3. Check the operation again.
Note! If the discharge chute will not stay in position,
adjust the pinion gear (B) closer to the ring gear (A).
6.6.5 Hexagonal shaft, Man
The hexagonal shaft, chain sprocket and chains are not to be
lubricated. All bearings and bushings are permanently
lubricated and require no maintenance.
Lubricating these parts will only result in the grease getting
on to the friction wheel and disc drive plate, which could
damage the rubber clad friction wheel.
For long time storage the above-mentioned parts should be
lightly wiped with an oily rag to prevent rust.
6.6.6 Hydrostat, HST
The hydrostatic transmission is factory-filled with oil at the
delivery. If it not has been opened (permitted to authorised
personell only) and if no leakage exist, there is no need for
filling-up. Normally, there is no need for oil change in the
transmissio
