 Insert the end of new 1/3 sheet sandpaper approximately
1/2 in. under the front paper clamp.
 Lift up on the lever on the right side of the sander and
lock into the slot on the platen. Apply downward pressure
to conform the sandpaper to the platen.
 Wrap sandpaper around the cushion and insert the loose
end of the sandpaper under the rear paper clamp. Fit the
sandpaper against the cushion as tight as possible.
 Lift up on the lever on the left side of the sander and lock
into the slot on the platen.
INSTALLING PRESSURE SENSITIVE
ADHESIVE SANDPAPER
See Figure 4, page 11.
 Unplug the sander.
 If replacing adhesive sandpaper, remove old sandpaper
by peeling it off the cushion.
NOTE: Sand for a few minutes to soften the adhesive
backing before attempting to remove old sandpaper.
 If replacing regular sandpaper, release the paper clamp
by lifting up on lever and disengaging it from the slot 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 1/3 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
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 sandpaper.
Remove the sandpaper soon after you have finished a sand-
ing operation. 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 sandpaper to become difficult to remove.
It may also tear when removing, making it difficult to clean
the backing pad for the next sheet of sandpaper.
NOTE: If you forget to remove the sandpaper after a sand-
ing operation, sand for a few minutes to soften the adhesive
backing before attempting to remove sandpaper.
OPERATION
DUST COLLECTION SYSTEM
The built-in dust collection system helps to keep the work
area clean.
WARNING:
To prevent the possibility of sanding dust or foreign
objects being thrown into your face or eyes, never
attempt to use the sander without the dust box assembly
properly installed. Sanding dust or foreign objects being
thrown into your face could result in possible serious
injury.
REMOVING AND EMPTYING THE DUST
COLLECTION BOX
See Figure 5, page 11.
WARNING:
Collected sanding dust from sanding surface coatings
such as polyurethanes, linseed oil, etc. can self-ignite
in the sander dust box or elsewhere and cause fire. To
reduce the risk of fire, always empty the dust box fre-
quently while sanding and never store or leave a sander
without totally emptying its dust box. Also follow the
recommendations of the coatings' manufacturers.
For more efficient operation, empty the dust collection box
when no more than half full. This will permit better air flow
through the box or filter.
Always empty and clean the dust collection box thoroughly
after each sanding operation and before storing the sander.
 Unplug the sander.
 To remove the dust collection box, grasp the ridges on
the sides and pull straight out.
 Remove the cover by pushing up on the tab.
 Remove the filter and shake to remove dust and debris.
 Shake the dust collection box to empty sanding dust.
 Replace the filter and cover.
 To reinstall the dust collection box, align the tab on the
box with the slot above the exhaust.
 Push the dust box until it snaps into place.
