BELT TENSIONS
(Units Manufactured Prior to 1-97)
Correct belt tension is critical for proper unit operation.
Belts that are too loose will slip, squeal or whip causing
excessive vibration levels and poor unit performance. Belts
that are too tight will cause excess vibration along with pre-
mature belt and bearing failures.
