WARNING:
Always wear safety goggles or
safety glasses with side shields when operating
your sander. Failure to do so could result in
foreign objects being thrown into your eyes,
resulting in possible serious injury, tf the sanding
operation is dusty, also wear a face or dust
mask.
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 atl 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.
Note: Do not use sander without sandpaper. Doing
so will damage the cushion.
PREPARING FOR OPERATION
,_
CAUTION:
Be careful not to let your hand cover
the air vents.
SANDING
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.
Hold your sander in front and away from you, keeping
it clear of the workpiece.
Start your sander by press-
ing 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 move-
ment. See Figure 4. Move if slowly using forward and
backward strokes.
_1= 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.

Do not force, The weight of the unit supplies ad-
equate 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 overheat-
ing 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 matedal, making
the surface uneven.
Flush sanding can be performed with your sander.
See Figure 5. The front edge of your sander allows
flush sanding in corners. Always remove sander from
workpiece before turning your sander off.
