OPERATION
TO ADJUST SANDING BELT TRACKING
See Figures 7 and 8.
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 directions to adjust sanding belt tracking.
WARNING:
Before connecting the sander to a power supply,
always make sure it is not in the “locked-on” posi-
tion. Failure to do so could result in accidental start-
ing 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 switch trigger and release immediately.
If sanding belt runs inward: Turn the tracking screw
slowly counterclockwise.
If sanding belt runs outward: Turn the tracking screw
slowly clockwise.
NOTE: Turn the tracking screw 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 screw.
Start the sander and fine adjust the tracking screw
until the belt stablizes.
WARNING:
Keep hands and fingers away from a moving sand-
ing 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 operat-
ing the sander. They could get caught in moving
parts and foreign objects could get thrown away
from the sander causing injury.
