Feed Belt Tension

To adjust the feed belt tension:

1.Disconnect the sander from the power source!

2.Move the emergency brake plate up and out of the way.

3.Tension adjustments are made using the bolts located on the left and right side of the front conveyor roller as shown in Figure 26.

4.When tensioned properly you should not be able to lift the belt off the conveyor surface or slide it back and forth, and it should not slip.

5.Perform the ÒFeed Belt TrackingÓ instructions to ensure that the tracking did not change during tensioning.

Feed Belt Tracking

To check the feed belt tracking:

1.Turn the feed belt ON.

2.If the belt moves to one side then you need to immediately stop the machine and adjust the belt tracking. If the belt tracks evenly, leave it alone.

To adjust the feed belt tracking:

1.Unplug the sander!

2.Use the adjustment bolts (one is shown in Figure 26) to correct the tracking.

3.Run the feed belt for a few minutes after the adjustment to allow the belt to move into its new position. When you are satisfied that the belt has finished moving, stop the feed belt.

4.If more adjustments are necessary, experi- ment with how the movement of the adjust- ment bolts affects the belt tracking; do this until you can make the feed belt track even- ly. Make sure you did not loosen the belt dur- ing the tracking process. If you did, adjust each side of one belt roller away from the machine, as evenly as possible.
