Belt Tracking

Tracking is the process of adjusting the belts so they remain centered on the drums. Always adjust the tracking after replacing a sanding belt. Neglecting to adjust tracking will damage sand- ing belts and they will need to be replaced before they are worn out.

To adjust the sanding belt tracking:

1.Disconnect the machine from power!

4.Move the tracking knob clockwise to move the sanding belt inwards or counter-clock- wise to move the belt outwards.

5.Tighten the lock handle.

6.Rotate the sanding belts by hand.

—If the belt remains centered in the drum, go to step 7.

—If the belt pushes against one edge of the sanding drum, return to step 3.

7.Connect the sander to power, then turn the sander ON and immediately turn it OFF. —If the belt remains centered in the drum,

continue to the next step.

—If the belt is not tracking correctly, return to step 3 and make fine adjustments until the sanding belt tracks in the center of the drum.

8.Turn the sander ON and allow it to run for several minutes without use.

—If the belt is not tracking correctly, return to step 3 and make fine adjustments until the sanding belt tracks in the center of the drum.

—If the belt remains centered in the drum, the sander is ready for use.
