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 eco-
nomical use in power sanding.
In general, coarse grit will remove the most material and
finer grit will produce the best finish in all sanding opera-
tions. The condition of the su#ace 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 sander without sandpaper. Doing so
will damage the cushion.

WARNING:
Do not wear loose clothing or jewelry
when operating sander. They could get caught in
moving parts causing serious injury. Keep head away
from sander and sanding area. Hair could be drawn
into sander causing serious injury.
ORBITAL
MOTION
See Figure 8.
Orbital motion is ideal for fast cutting action when
removing old finishes, smoothing rough wood, cutting
stock down to required dimensions, or for finishing
surfaces to be painted. As shown in figure 8, the
sandpaper moves in tiny circles at a very high speed,
allowing the sander to move easily.

Flush sanding can be performed with your sander. See
Figure 9. Every side except the rear of your sander allows
flush sanding in corners. Always remove sander from
workpiece before turning your sander off.

REMOVING
SANDPAPER
BEFORE
STORAGE
Do not store your sander with pressure sensitive adhesive
sandpaper installed. Heat generated from sanding causes
the pressure sensitive adhesive to flow and form a tight
bond between the cushion and sandpaper.
Removing the sandpaper soon after you have finished a
sanding operation avoids letting the adhesive set up. If the
sandpaper is left on the cushion 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. When this situation
occurs, it becomes difficult to clean the cushion for the
next piece of sandpaper.
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.
