OPERATION
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.
In general, when sanding, coarse grit removes the most ma-
terial and fine grit produces the best finish. The condition 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.

n
Unplug the sander.
WARNING:
Failure to unplug the tool could result in serious injury
due to accidental starting.
n 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.
n Raise the tension release lever.
NOTE: If you are changing sanding belts, remove the old
sanding belt at this time.
n 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.
n Align the sanding belt to its correct position.
n Lower the tension release lever to secure the sanding
belt.
