TURNING THE SANDER ON/OFF
See Figure 2, page 10.
To turn the sander ON:
 Insert the battery pack.
 Depress the switch trigger.
To turn the sander OFF:
 Release the switch trigger.
LOCK-ON BUTTON
See Figure 2, page 10.
The lock-on feature allows you to lock the switch trigger in
the ON position. Locking the switch trigger on allows you to
operate the sander for extended periods of time.
If you have the lock-on feature engaged during use and the
battery pack is removed from the sander, disengage the lock-
on feature immediately. Also, do not lock the switch trigger
if you might need to suddenly stop the sander.
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.
To lock- on the sander:
 Depress the switch trigger.
 Push in the lock-on button.
 Release the switch trigger.
 Release the lock-on button.
NOTE: To release the lock, depress and release the switch
trigger.
VARIABLE SPEED SWITCH
See Figure 3, page 10.
The variable speed switch, located on the top of the tool,
allows the belt sander to operate at different maximum
speeds. The maximum speed can be adjusted before or
during operation. To change the maximum speed during
operation, hold the belt sander in a normal operating posi-
tion, fully depress the switch trigger, and slide the lever
forward or backwards. To change the maximum speed prior
to operation, slide the lever forward or backwards, and then
depress the switch trigger to operate the sander between
880 FPM and 2,065 FPM.
SELECTING SANDING BELTS
Selecting the correct size and type of sanding belt is an
important step in achieving a high quality sanded finish. Alu-
minum oxide, silicon carbide, and other synthetic abrasives
are best for power sanding.
OPERATION
In general, when sanding, coarse grit removes the most
material and fine grit produces the best finish. The condi-
tion of the surface to be sanded determines which grit will
do the best job. If the surface is rough, start with a coarse
grit and sand until the surface is uniform. Then use medium
grit to remove scratches left by the coarser grit. Finally, use
finer grit for finishing the surface. Always continue sanding
with each grit until the surface is uniform.
USING SANDING BELTS
See Figures 4 - 5, page 11.
To install/change sanding belts:
 Remove the battery pack.
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.
TO ADJUST SANDING BELT TRACKING
See Figure 6, 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.
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.
Follow these steps to adjust sanding belt tracking.
