General Rules For Belt Tensioning

1. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions
2.  Over-tensioning shortens belt, motor bearing, and fan bearing life.
3.  Keep belts free from foreign material which may cause slip.
4.  Never apply belt dressing.  this will damage the belt and cause early failure.
