TO OPERATE
When applicable, clamp or otherwise secure the work
to prevent it from moving under your sander.

WARNING:
Unsecured work could be thrown
towards the operator causing injury.
SANDING
See Figures 8 and 9.
Fig. 8
Fig. 9
Hold sander in front 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 it
slowly over workpiece using forward and backward or
side to side strokes. Upon completion of sanding
operation, always remove sander from workpiece
before turning it off.
DO NOT FORCE. The weight of the unit supplies
adequate
pressure, so let the sandpaper and sander
do the work. Applying 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
sander's rapid action may remove too much material,
making the surface uneven.
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 efficient 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
uniformly smooth. Medium grit may then be used to
remove scratches left by the coarser grit. Finer grit is then
used for finishing the surface. Always continue sanding
with each grit until surface is uniformly smooth.

WARNING:
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.
