1. First item you check is the bed for square.  which is done by measuring corner to corner. (Figure 1)

2. Make sure that the bed is level from end to end and side to side. If there is more than one bed, run a string from the center of  each end to make sure there is no bow in the bed set up. A banana type bow can cause tracking problems. (See Figure 2)

3.Make sure the drive and take-up pulleys are level with the bed.

    If the pulleys are not level the belt will track hard to the “low” side. To help solve this loosen the bearing bolts on the side that the belt rides toward and adjust the pulley “up” to move the belt toward the center of the pulley. (See figure 3).

4.After you are sure that the conveyor is level and the pulleys are level with the conveyor your next check is the belt tension. The belt should be only tight enough to drive the belt. OVER tightening the belt can cause major belt and-or pulley damage. ■
