- Loosen lock nut D of the V-belt tensioning bolt,
- Loosen V-belt tensioning nut G to the extent that you can remove the V-
belts,
- Remove the old belts and fit the new belts around the pulleys,
- Turn nut G to tension the V-belts,
- Pull (for instance using a spring balance) at a belt midway between the two
pulleys with a force F of 5 daN (5.1 kg).
- The V-belt tension is correct when in doing so the belt is pulled away by not
more than 5-6 mm.
- Check with straight edge K whether the pulleys are properly aligned,
- Adjust the alignment, if necessary, by placing one or more rings N between
base plate O and gearbox plate P,
- After adjusting the alignment, it is necessary to recheck V-belt tension,
- Retighten all bolts and nuts in reverse order of removal,
- Mount the V-belt guard.

Tensioning the V-belts. (see figure 7.6.1)
-
Remove the V-belt guard,
- Loosen nuts C and D,
- Turn nut G until reaching the correct V-belt tension (see above). Do not
forget to check pulley alignment,
- Retighten nuts C and D, and amount the V-belt guard.
Note:
First-time retensioning must be carried out after about 1-2
operating hours. The tension and condition of the V-belts are
subsequently to be checked at regular intervals.

Winter storage.
In the event the machine is put out of service for an extended period of time, it will be
necessary to carry out an extensive cleaning. Thereupon, lubricate all greasing points
(see chapter 7.3.) and change the gearbox oil (see chapter 7.5.). After this, have the
machine run for a few minutes.
