Sanding
Cleaning the dust box
Selecting the correct grit and type of sandpaper
is extremely important 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 most material.
Fine grit will produce the best finish in all sanding
operations. The condition of the surface to be and-
ed will determine which grit will do the best job.
DO NOT FORCE THE SANDER.
The weight of
the sander usually provides adequate pressure.
Let the sander and sandpaper do the work.
Applying added pressure will slow the motor,
increase the wear on the sandpaper and greatly
reduce sander speed. Excessive pressure will
overload the motor causing possible damage
from the motor overheating. It will also create
an inferior finish on sanded work. Any finish or
resin on wood will soften from the frictional heat,
causing sandpaper to become clogged quickly. Do
not sand in one spot too long as the sander’s rapid
action may remove too much material, making the
surface uneven.
Extended periods of sanding may tend to overheat
the motor. If this occurs, turn sander OFF, wait
until the sanding pad comes to a complete stop
and remove it from the workpiece. Check to make
sure your hands have not been covering the
cooling vents. Let the motor cool before continuing
sanding operation.
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. Fine grit should be used for finishing
the surface. Always continue sanding with each grit
until the surface is uniform.
The dust box will collect much of the sanding dust
that is generated during sanding operations. As a
result, it must be cleaned out periodically so the
dust collection will be efficient.
Clamp or otherwise secure your workpiece to pre-
vent it from moving under the sander while being
sanded. Secure the workpiece in a vice if possible.
Place the sander on the workpiece so the com-
plete sanding pad surface is in contact with the
workpiece. Turn the sander ON by squeezing the
trigger switch. Move the sander slowly over the
workpiece making successive passes in parallel
lines. When sanding wood, make sure you move
the sander parallel to the grain and not across the
grain. This will make finish sanding more efficient
and smoother.
Upon completion of the sanding operation, turn
sander OFF by squeezing and releasing the switch
trigger. Wait until the sanding disc comes to a com-
plete stop before removing it from the workpiece.
NOTE:
Where the sandpaper grits are shown numerically, higher
numbers indicate finer grit and lower numbers indicate
coarser grit.
NOTE:
Hold the sander with two hands, using both the front and
main handles. Be careful NOT to cover the motor cooling
vents with your hands. Covering the cooling vents could
cause the motor to be damaged by overheating.

WARNING:
Any unsecured workpiece could be thrown toward the
operator causing injury.
WARNING:
Your sander should only be turned ON when the entire
surface of the sanding pad is in contact with the work
-
piece. Failure to follow this sanding procedure could result
in loose sandpaper which could result in possible injury.
