Adjusting Belt Tension
Belt tension is set at the factory. If slippage is detected, reset the
tensions as follows:
After the first 200 to 500 running hours or at any time chirping is
heard on start up, check the belt tension. If tension is below 25 pounds
on any belt, increase the center distance using the motor slide base
so that belt tension is 45 to 50 pounds. The motor slide base details
are shown below. If installing new belts see the procedure below.

New Belt Installation Procedure
1. Loosen the two slide bolts near the motor pulley and the two
slide bolts on the front edge of the base. Keep enough torque on
them to take up any slack between the slider and the main base,
but enough slack to allow the slider to move.
2. Tighten the belt adjustment bolt using a torque wrench to 45
inch pounds. This will bring the belts to the proper tension.
3. Tighten the slider bolts, the two on the front edge of the base,
then the two slider bolts closest to the motor pulley so the belt
tension is 45 to 50 pounds.
