OPERATION
TO ADJUST SANDING BELT TRACKING
See Figures 5 and 6.
Belt life is greatly increased if you regularly adjust the
sanding belt tracking. When correctly adjusted, the
outer edge of the sanding belt should be even with the
outer edge of the base of the sander.
When you install a new sanding belt, you may need to
adjust the sanding belt tracking several times until the
belt becomes pliable.
Follow these steps to adjust sanding belt tracking.
A WARNING: Before connecting the sander to a
power supply, always make sure it is not in the
“locked-on” position. Failure to do so could result in
accidental starting of the sander resulting in
possible serious injury.
■ Connect the sander to a power supply.
■ Position the sander upside down with the cord on
the left.
Note: This position is for adjustments only. The
sanding belt should not contact a workpiece or any
foreign object when you are making belt tracking
adjustments.

Depress the trigger switch and release immediately.
Choose one of these options:
■ Sanding belt runs inward: Turn the tracking knob
slowly clockwise.
■ Sanding belt runs outward: 1 urn the tracking
knob slowly counterclockwise.
Note: Turn the tracking knob until you are sure the
sanding belt is secure, i.e., it will not come off the
sander or contact internal parts.
CAUTION: If the sanding belt wears excessively
^ on the inner edge, it is probably adjusted too far
inward and is rubbing against internal parts. If this
is the case, readjust the tracking knob.
Start the sander and fine adjust the tracking knob
until the belt stabilizes.
WARNING: Keep hands and fingers away from a
* moving sanding belt. Any part of the body coming
in contact with a moving sanding belt could result
in serious injury. Do not wear loose clothing or
jewelry when operating the sander. They could get
caught in moving parts and foreign objects could
get thrown away from the sander causing injury.
