INSTALLING/CHANGING SANDING BELTS
See Figures 1 - 3, page 11.
 Unplug the sander.
 Position the sander on its side with the cord on the left.
WARNING:
Keep hands and fingers clear of both rollers and spring
mechanism at all times. Failure to do so could result in
fingers getting pinched, causing serious injury.
 Raise the tension release lever.
NOTE: If you are changing sanding belts, remove the old
sanding belt at this time.
 Install the sanding belt.
CAUTION:
If the sanding belt is not a bidirectional belt, ensure that
the arrow inside the belt is pointing in the direction of the
rotation (clockwise when looking into the open side of the
sander). Installing unidirectional sanding belts backwards
can create a hazardous condition.
 Align the sanding belt to its correct position.
 Lower the tension release lever to secure the sanding
belt.
ADJUSTING SANDING BELT TRACKING
See Figures 4 - 5, page 11.
Belt life is greatly increased if you regularly adjust the sand-
ing 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
conditioned.
Follow these steps to adjust sanding belt tracking.
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 switch trigger and release immediately.
OPERATION
 Choose one of these options:
 Sanding belt runs inward: Turn the tracking knob slowly
counterclockwise.
 Sanding belt runs outward: Turn the tracking knob
slowly clockwise.
NOTE: Turn the tracking knob until you are sure the sand-
ing belt is secure, i.e., it will not come off the sander or
contact internal parts.
NOTICE:
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.
USING THE DUST COLLECTION BAG
The dust collection bag provides a dust collection system
for the sander.
WARNING:
Do not use the dust collection bag when sanding metal.
Using the dust collection bag when sanding metal creates
a fire hazard, which could damage the tool and lead to
serious personal injury.
ATTACHING THE DUST COLLECTION BAG
See Figure 6, page 12.
 Unplug the sander.
 Slide the dust bag retainer over the blower exhaust hole
on the sander.
EMPTYING THE DUST COLLECTION BAG
For more efficient operation, empty the dust collection bag
when it is no more than half full. This action permits the air
to flow through the bag better. Always empty and clean the
dust collection bag thoroughly upon completion of a sanding
operation and before placing the sander in storage.
