*** Note: Allow the oil enough time to sink through the bearings.
Wipe off excess oil to prevent it reaching the V-belts as oil and grease cause unnecessary slipping and extra wear.
Refill the gearbox to required oil level and refit the breather. Fill up only to the proper level.

1.8 V-Belts
A correct V-belt tension is very important and must be checked prior to use and after 2, 8
and 16 hours for proper adjustment. Thereafter you should check the tension at regular
intervals, at least every 50 hours.
The V-belts do have the right pré-tension when can displace the V-Belts (one by one)
7,5mm with a force of 8kg (what you can push with your thumb) .
The control opening for the "push-pin" do you find at the rear side of the V-belt housing.
The V-belts of the machine are tensioned a bolt. With this bolt the gearbox is moved
until the correct belt tension is reached. Before changing the V-belts, it must be
completely relaxed.
First loosen the 6 bolts (red arrow) of the gearbox plate, so that it can slide. Then move
the gearbox with the bolt (green arrow) so that the V-belts are tensioned.
Finally retighten the bolts of the gearbox plate.
Remark: When new V-belts are mounted, always make a test run and check the V-belt tension again!!!
