W1730 Oscillating Edge Sander
Belt Tracking
After the sanding belt has been removed or replaced, or used for a significant amount of time, it may be necessary to adjust the sanding belt tracking.
To adjust the sanding belt tracking, do these steps:
1.Turn the machine ON long enough to observe the tracking of the sanding belt, then turn it OFF.
2.If the sanding belt does not track on a centered path across the rollers, adjustment is necessary.
3.Unplug the sander!
4.Loosen the jam nut shown in Figure 22.
5.Determine if the sanding belt is tracking too high, or too low:
•If the belt tracks above center, turn the adjustment nut, shown in Figure 22, counterclockwise.
•If the sanding belt tracks below center, turn the adjustment nut clockwise.
6.Tighten the jam nut.
7.Connect the machine to power and turn ON. Observe the belt tracking behavior for at least two minutes:
• If the belt is tracking correctly, no further adjustment is necessary.
• If the belt is not tracking correctly, repeat Steps 3-7.
