Operating and Maintenance Manual

Drive Belts


Belts should be examined each month for tension, alignment and any signs of wear. If one belt in a matched set is found to be damaged the whole set is to be changed.

Extreme care must be taken when tensioning belts, excessive tension will cause overloading of bearings and cause damage to bearings, shafts & belts.

Insufficient tension will cause belts slip leading to excessive noise and belt wear.
