Tracking

Tensioning

The conveyor may slightly stretch with continued use and will eventually need to be tensioned. This is most obvious if the conveyor starts slipping on the rollers.

When you tension the conveyor, focus on turning the adjustment bolts in even increments. Tensioning one side more than the other will cause tracking problems, which will require you to take additional steps to get the sander operating correctly.

To tension the conveyor, do these steps:

1.Using a 19mm wrench, loosen the lock nut (see Figure 47) on both sides of the conveyor.

2.Measure the distance from the frame to the convey- or roller on both sides. Turn the adjustment bolts so the distance between the frame and conveyor roller is identical on both sides. Do not overtighten the conveyor. Your goal is to reach a 3/4" gap between the underside of the conveyor and the belt, as shown in Figure 48.

3.Use a magic marker, white out, or fingernail polish to mark the front of the conveyor tensioning bolt on both sides.

This step will aid you in keeping track of the rotations as you turn the bolts, so the bolts remain as even as possible.

4.Turn both of the conveyor adjustment bolts clock- wise one full turn at a time until the conveyor belt no longer slips during operation.

—If the conveyor starts tracking to one side, imme- diately turn the drum sander OFF and perform the tracking instructions.

5.Tighten the lock nuts to lock the conveyor adjust- ment bolts in place.

Loose hair and clothing could get caught in machinery and cause serious personal injury. Keep loose clothing rolled up and long hair tied up and away from machinery.
