On Center Drive Units, set the take-up pulley (See Figure 2) to its full retracted position by loosening the jam nuts on both adjuster screws and running out the adjuster screws to their maximum. If provided, set both tail pulleys to their full retracted position by loosening the flange bearing bolts on both ends of the pulley and running out the adjuster screws to their maximum. Unroll the conveyor belting, and pull belting along conveyor bed with the carrying side up. Note: With standard PVC black belting, the smooth, dark black surface must be installed up for normal operation. Installation with this surface down will cause excessive friction and increased drive force.
