■
pack snap into place and the battery pack is secured
on the tool before beginning operation.

■
Remove the battery pack from the tool.

SANDING DISC SELECTION
Selecting the correct size grit and type sanding disc 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.
TURNING THE SANDER ON ( I )/OFF ( O ) (Fig.3)
Install the battery pack.
■
To turn ON the sander: press down the ON ( I ) side
■
of the switch.
To turn OFF the sander: press down the OFF ( O )
■
side of the switch.
ATTACHING HOOK-AND-LOOP SANDING DISC (Fig.
4)
To attach hook-and-loop sanding disc:
Remove battery pack from sander.
■
Align the holes in the sanding disc with the holes in
■
the hook-and-loop backing pad.
Press the sanding disc against the backing pad as
■
firmly as possible.
NOTE: To provide for the best adhesion, we
recommend that you clean the backing pad and the
sanding disc backing occasionally by brushing them
lightly with a small brush.

OPERATING THE SANDER (Fig.5)
Secure the workpiece to prevent it from moving
■
during operation.
WARNING:
Unsecured workpieces could be thrown towards
the operator causing injury.
WARNING:
Keep your head away from the sander and the
sanding area. Your hair could be drawn into the
sander, causing serious injury.
Place the sander on the workpiece so that all of the
■
sanding disc surface is in contact with the workpiece.
CAUTION:
To avoid motor damage resulting from
overheating, do not cover the air vents with your
hand.
Turn on the sander and move it slowly over the
■
workpiece. Make successive passes in parallel lines,
circles or crosswise movements.
Turn off the sander and wait until the sanding disc
■
comes to a complete stop before removing it from the
workpiece.
Do not force. The weight of the sander supplies
adequate pressure to do the work. Applying additional
pressure only slows the motor, rapidly wears the sanding
sheet and greatly reduces sander speed. Excessive
pressure will overload the motor causing possible
damage from overheating and can result in inferior work.
Any finish or resin on wood may soften from the frictional
heat. Do not sand 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 overheat the motor. If
this occurs, turn the sander off and wait until the sanding
sheet comes to a complete stop. Remove sander from
workpiece. Remove sanding disc, then turn sander on
and run it free without a load to cool the motor.
