Vertical Belt
Tracking
Through normal operation, sanding belts become worn on the inside and outside surfaces, which can cause the belt to track too high or too low on the platen and pulleys. See Figure 28.
You can compensate for this normal wear by adjusting the belt tracking knobs.
Keep your machine unplugged during all assembly, adjustments, or maintenance proce- dures. Otherwise serious personal injury may occur!
To adjust the vertical belt tracking, do these steps:
1.Unplug the edge sander.
2.Loosen the belt tracking lock knob. See
Figure 29.
3.With the sander unplugged, turn the belt tracking knob in either direction while you rotate the sanding belt See Figure 29. The belt will track higher or lower depending on which direction you turn the belt tracking knob.
4.When the belt tracks in the center of the platen, tighten the belt tracking lock knob.
5.Rotate the belt a few more times to make sure the belt stays in the normal operating position. If it does not, repeat steps 1 through 5.
