Conveyor Belt Tension

and Tracking

The conveyor belt tension and tracking has been set at the factory. However, adjust the conveyor belt tension and tracking if you notice that your conveyor belt is slipping or is tracking off center, or loading up against the positioning wheels (Figure 32) under the conveyor table.

To adjust the conveyor belt tension and tracking, do these steps:

1.Lift the emergency stop push panel so it contacts the safety stop shown in Figure 31. The safety stop prevents the top edge of the push panel from tearing the conveyor belt when you lift the push panel during conveyor tracking adjustments.

2.From side-to-side, turn the conveyor belt tension and tracking screws equal amounts so the belt tension is snug and will not slip on the rollers when sanding at a maximum load.

3.Start the conveyor.

4.Turn the conveyor belt tension and tracking screws again as required to position the conveyor belt roller evenly on each side. See Figure 32.

—If the conveyor tracks to the right, turn the right-side tension and tracking screw clockwise approximately in 1⁄4 turn increments.

—If the conveyor tracks to the left, turn the left-side tension and tracking screw clockwise in approximate- ly 1⁄4 turn increments.

5.Run the conveyor belt for at least ten minutes to determine if the tracking is correct and the tension stays the same.

6.Repeat steps as required to achieve the correct tension and tracking.
