PREPARING
FOR OPERATION
_lb CAUTION:
Be careful net to let your hand cover the
air vents.
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 3 and 4.
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. De 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
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.
,_lb 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.
LUBRICATION
All of the bearings in this tool are lubricated with a suffi-
cient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication is required.
