ASSEMBLY
The backing pad on your sander provides the capability to use sanding discs with pressure sensitive adhesive back- ing material. You also receive a conversion pad which al- lows use of sanding discs with velcro type backing mate- rial.
SANDING DISC SELECTION
Selecting the correct size grit and type sanding disc 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.

TO ATTACH PRESSURE SENSITIVE ADHESIVE SANDING DISC
See Figure 2.
Unplug your sander.
Carefully peel paper backing from the pressure sensitive adhesive type sanding disc.
Align holes in sanding disc with holes in backing pad, then carefully press sticky side of disc against pad as tight as possible.
NOTE: Holes in sanding disc must line up with holes in the backing pad in order for the dustless feature of your sander to function properly.
NOTE: It is recommended that you clean backing pad occasionally by brushing lightly with a small brush. Dust buildup on backing pad could cause sanding disc not to stick properly.

REMOVING SANDINGDISCBEFORESTORAGE
Do not store your sander with the sanding disc 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 sanding disc soon after you have finished a sanding operation avoids letting the adhesive set up. If the sanding disc 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 sanding disc after a sanding operation, sand for a few minutes to soften the adhesive backing before attempting to remove sanding disc.
