Note! If the discharge chute will not stay in position, adjust the pinion gear (B) closer to the ring gear (A).

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).
