WARNING:
Unsecured work could be thrown towards the operator,
causing injury.
WARNING:
Keep hands away from blades. Do not reach underneath
work or around or over the blade while blade is moving.
Do not attempt to remove cut material when blade is
moving.
CUTTING
See Figure 5, page 9.
 Mark the line of cut clearly.
 Hold the tool firmly in front of and clearly away from you.
Make sure blade is clear of any foreign material.
 Depress the switch trigger to start the cutting action. Allow
the blade to come to full speed, then move the blade into
the work.
 To cut, keep the teeth of the blade in the workpiece sur-
face and move the back of the tool slowly in a constant
sideways motion.
NOTE: If the line and writing on the blade looks blurry
when in use, you are using the correct amount of pressure.
If they become clear, you are using too much force.
NOTICE:
Do not force. Use only enough pressure to keep the saw
cutting. Let the blade and saw do the work. Use of ex-
cessive pressure will cause strong vibrations to the tool,
which may result in broken blades and cause premature
wear to the tool's motor.
OPERATION
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 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.
SANDING
See Figure 6, page 9.
Hold sander in front of and away from you, keeping it clear
of the workpiece. Start sander and let the motor build to its
maximum speed, then gradually lower on the work with a
slight forward movement. Move the sander slowly over work-
piece using forward and backward or side to side strokes.
Upon completion of sanding operation, always remove
sander from workpiece before turning it off.
Do no t fo rce. The weight of the unit supplies adequate
pressure, so let the sandpaper and sander do the work. Ap-
plying additional pressure only slows the motor, rapidly wears
sandpaper, and greatly reduces sander speed. Excessive
pressure will overload the motor causing possible damage
from motor overheating and can result in inferior work. Any
finish 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.
