nish. Aluminum oxide, silicon carbide, and
other synthetic abrasives are best for power sanding.
Natural abrasives, such as fl int and garnet are too soft for
economical use in power sanding.
In general, coarse grit will remove the most material
and fi ner grit will produce the best fi nish 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 fi ner grit used for
fi nishing of the surface. Always continue sanding with
each grit until surface is uniform.
WARNING
Do not use sander without sandpaper, doing so will
damage the cushion.
PREPARING FOR OPERATION
CAUTION
Be careful not to let your hand completely cover air
vents.
SANDING
See Figure 1.
WARNING
Unsecured work could be thrown towards the operator
causing injury.
Hold your sander in front and away from you, keeping it
clear of the workpiece. Start your sander by pressing the
switch button to "on" position and letting the motor build to
its maximum speed. Gradually lower your sander on the
work with a slight forward movement. Move it slowly using
forward and backward strokes.
Do not force.
The weight of the unit supplies adequate
pressure, so let the sanding disc and sander do the work.
Applying additional pressure only slows the motor, rapidly
wears sanding disc and greatly reduces sander speed.
Excessive pressure will overload the motor causing
possible damage from motor overheating and can result in
inferior work. Any fi nish or resin on wood may soften from
the frictional heat.
Do not allow sanding on 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 and wait until sanding
disc comes to a complete stop, unplug the sander, then
remove it from workpiece. Allow the tool to cool down.
ORBITAL MOTION
See Figure 2.
Orbital motion is ideal for fast cutting action when removing
old fi nishes, smoothing rough wood, cutting stock down to
required dimensions or for fi nishing surfaces to be painted.
The sandpaper moves in tiny circles at a very high speed,
allowing the sander to move easily.
WARNING
Collected sanding dust from sanding surface coatings
such as polyurethanes, linseed oil, etc., can self-ignite
in your sander dust collection box or elsewhere and
cause fi re. To reduce the risk of fi re always empty your
dust collection box frequently (10-15 minutes) while
sanding and never store or leave a sander without
totally emptying its dust collection box. Also follow the
recommendations of the coatings manufacturers.
USING THE DUST BAG ASSEMBLY
The dust bag assembly provides a dust collection system
for the sander. Sanding dust is drawn up through the holes
of the sanding disc and collected in the dust bag during
sanding.
TO ATTACH THE DUST BAG ASSEMBLY
See Figure 3.
Follow these directions to attach the dust bag assembly.
1. Unplug the sander.
WARNING
Failure to unplug the tool could result in accidental
starting causing possible serious injury.
2. Using a slight twisting motion, fi rmly slide the dust
collection bag assembly in the blower exhaust on the
sander.
EMPTYING THE DUST COLLECTION BAG ASSEMBLY
See Figure 4.
For more effi cient operation, empty the dust collection
box when it is no more than half full. This will permit the
air to fl ow through the dust collection box better. Always
empty and clean the dust collection box thoroughly upon
completion of a sanding operation and before placing the
sander in storage.
