Drive Belt Tension - GEISMAR STUMEC MP.12 Instruction Manual

5.1.5 Drive belt tension (the engine must be off)
The drive belt is tensioned by variation of the pitch diameter of the pulleys through a clamp set. The drive pulley and the receiving pulley are both adjustable.
To access the pulleys, dismount the grinding wheel, the grinding wheel housing and the belt housing.
Every 50 hours of operation, check the belt tension and adjust it if necessary as follows:
- Dismantle the pulley flange ① kept in place by bolts ③
(see fig; 1).
- Remove a clamp ②.
- Replace the flange ①, placing the clamp between the flange and
the bolts ③.
-
Progressively tighten the six bolts ③, while turning the pulley by
hand so the belt moves into position without becoming stuck
between the two flanges.
- If the resulting tension is not enough, start the operation again to
remove another clamp ②.
To guarantee proper alignment of the drive belt, you must carry out the same adjustment on each of the pulleys.
When there are no more clamps between the flanges of the two pulleys and the belt is slipping, a new belt must be installed in its place.
To install a new belt, put all of the clamps (12 per pulley) between the pulley flanges.
NOTE: When replacing or re-installing a belt, check that the pulley grooves are in good condition and clean them, and those of the belt, carefully.
Check the belt tension after 10 hours of use, then check and adjust it, if necessary, after every 50 hours of use.
