Belt Tension Adjustment

Proper belt tension is critical to good performance. After 1/2 hour
of operation, all cables may have to be adjusted due to initial
stretch. Thereafter, check tension after every 2 hours of operation.
To increase belt tension:
1. Turn jam nut clockwise in 1/8 in. (3 mm) increments.
2. Check adjustment.
To decrease belt tension:
1. Turn jam nut counter-clockwise in 1/8 in. (3 mm) increments.
2. Check adjustment.
3. This procedure can be repeated until conduit adjustment bolts
are fully adjusted. If no more adjustment can be made, belt
may have to be replaced.
