ADJUSTING BELT TENSION
1. Correct belt tension is obtained when there is
approximately 1" deflection at the center span of the
belt using light finger pressure.
2. If an adjustment is required, the motor can be raised
or lowered to obtain the correct belt tension.
3. Tighten motor mounting hardware after tension is
applied, making sure alignment of the pulleys is not
disturbed.
