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.
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.
