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 material.
WARNING:
Your sander should never be connected to power supply
when you are assembling parts, making adjustments,
assembling or replacing sanding disc, cleaning, or when not
in use. Disconnecting your sander will prevent accidental
starting that could cause serious personal injury.

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.
