Do not attempt to modify this product or create
accessories or attachments not recommended for use
with this product. Any such alteration or modification is
misuse and could result in a hazardous condition leading
to possible serious personal injury.

OPERATION

Selecting the correct size grit and type sandpaper is an
extremely important step in achieving a high quality sanded
finish. Aluminum oxide, silicon carbide, and other synthetic
abrasives are best for power sanding. Natural abrasives,
such as flint and garnet are too soft for economical use in
power sanding.
In general, coarse grit will remove the most material and finer
grit will produce the best finish in all sanding operations. The
condition of the surface to be sanded will determine which
grit will do the job. If the surface is rough, start with a coarse
grit and sand until the surface is uniform. Medium grit may
then be used to remove scratches left by the coarser grit and
finer grit used for finishing of the surface. Always continue
sanding with each grit until surface is uniform.
NOTE: Do not use the sander without sandpaper. Doing so
will damage the cushion.
PAPER PUNCH
See Figure 2, page 10.
A paper punch template is included for aligning and punch-
ing holes in sandpaper. The punched holes must align with
the holes in the sander cushion.
 Install sandpaper on the sander.
 Align the sander cushion over the paper punch.
 Push down on sander.
INSTALLING NON-ADHESIVE SANDPAPER
See Figure 3, page 11.
This sander accepts 1/3 sheet non-adhesive sandpaper.
Inspect sandpaper before installing. Do not use if broken
or defective.
 Unplug the sander.
NOTE: Removing the dust box assembly will make install-
ing non-adhesive sandpaper easier. Always remember to
replace the dust box assembly before beginning operation.
 If replacing sandpaper, remove the old sandpaper. A lever
is located on each side of the sander. Release the paper
clamps securing the sandpaper by lifting up on each lever
and disengaging from the slot in the platen.
