Belt Tracking/Tension
Belt tension and tracking are crucial to the per-
formance of the belt sander. Too much tension
will cause undue stress on the bearings and
other parts. Too little tension will cause the
sanding belt to not track properly and fall off
the sanding belt frame. It is better to have the
least amount of tension required to make the
belt track properly while under load.
To adjust the tracking:
1. Unplug the combination sander!
2. Unlock the quick release lever on the side of
the sanding unit by shifting it to the left.
3. Slide a 6" x 48" sanding belt onto the belt
sanding frame as shown in Figure 18.
4. Shift the quick release lever to the right to
tension the sanding belt.
5. To check the tracking, plug in and quickly
turn the sander on and off, and watch the
path of the belt. If it moves to either side,
the tracking needs to be adjusted.
6. Turn the tracking knob 1 ⁄
4
turn clockwise to
adjust the sanding belt towards the tracking
knob, and turn counter-clockwise to adjust
the sanding belt away from the tracking
knob as shown in
Figure 19.
7. Quickly turn the machine on and off again to
see if the tracking has improved. If not,
repeat the above steps.
8. If the tracking is fairly well maintained,
leave the machine running and fine tune the
sanding belt by further adjusting the track-
ing knob.

NOTICE
It is best to adjust the tracking of the sanding
belt before making any tension adjustments.
If you have trouble maintaining proper track-
ing after several attempts, you may need to
adjust the belt tension. Improper tension can
often times be the cause of tracking problems.
Always install belt according to the arrow
direction on the inside of the belt. Belts
installed incorrectly can fall apart, causing
serious personal injury.
