7 SERVICE AND REPAIRS

ENGLISH

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

7.2ADJUSTING THE SCRAPER BLADE AND SHOES

The scraper blade and shoes gets worn after a long term of use.

Adjust the scraper blade (always together with the shoes) until desired distance to the ground.

The scraper blade and the shoes are reversible and can be used on both sides.

See “5.8”.

7.3GENERAL ABOUT BELTS

The drive belts should be checked (and adjusted if required) for the first time after 2 – 4 hours use and then the middle of each season. They should thereafter be checked twice a year.

The belts are specially designed for this machine. They must be replaced by new genuine belts provided by your retailer or authorised service station.

When the belts are adjusted or replaced, the control wires must also be adjusted (see below).
