APPLICATIONS
You may use this tool for the purposes listed below:
 Sanding on wood surfaces.
 Removing rust from and sanding steel surfaces.
 Sanding plastics.
INSTALLING NON-ADHESIVE SANDPAPER
See Figure 2, page 13.
Inspect sandpaper before installing. DO NOT use if broken
or defective.
 Unplug the sander.
 If replacing sandpaper, remove old sandpaper. To remove
paper, release paper clamp by lifting up on lever, and
disengaging it from the tab, and allowing the lever to
lower.
 Insert end of new 1/4 sheet sandpaper approximately 1/4
in. under the paper clamp.
 Lift up on lever and lock into place. Apply downward
pressure to conform sandpaper to platen.
 Wrap sandpaper around cushion. Lift lever on opposite
end of sander and insert loose end of sandpaper under
paper clamp. Fit sandpaper tight against cushion.
 Lift up on lever and lock into place.
 Multiple sheets of sandpaper can be installed at one time
for convenience.
INSTALLING ADHESIVE SANDPAPER
See Figure 2, page 13.
Inspect sandpaper before installing. DO NOT use broken
or defective sandpaper.
 Unplug the sander.
 If replacing sandpaper, remove old sandpaper by peeling
it off cushion. If removing regular sandpaper, release paper
clamp by lifting up on lever and disengaging it from the
tab on the platen.
 Remove non-adhesive sandpaper, then lift up on paper
clamp lever and lock it into place.
 Carefully peel adhesive backing from new 1/4 sheet
sandpaper.
 Position sandpaper, making sure front edge of sandpaper
is aligned with front edge of the cushion, then carefully
press sticky side of sandpaper on cushion.
NOTE: Sandpaper must be aligned with the front edge
of the cushion for proper functioning of the flush sanding
feature.
REMOVING PRESSURE SENSITIVE ADHESIVE
(PSA) SANDPAPER BEFORE STORAGE
Do not store the sander with the sandpaper installed. Heat
generated from sanding causes the pressure sensitive
adhesive to flow and form a tight bond between the backing
pad and sanding disc.
Removing the sandpaper soon after you have finished a
sanding operation avoids letting the adhesive set up. If the
sandpaper is left on the backing pad for an extended period
of time after use, the adhesive will set up and cause the
sanding disc to become difficult to remove.
It may also tear when removing. When this situation occurs,
it becomes difficult to clean the backing pad for the next
sanding disc.
NOTE: If you forget to remove the sandpaper after a sanding
operation, sand for a few minutes to soften the adhesive
backing before attempting to remove sandpaper.
PAPER PUNCH
See Figure 3, page 13.
A paper punch template has been supplied with the sander
for aligning and punching holes in sandpaper. The punched
holes must align with the holes in the sander cushion.
 Install sandpaper on the sander.
 Align sander cushion over the paper punch.
 Push down on sander.
SANDPAPER SELECTION
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.
