OPERATION

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.
ATTACHING HOOk AND LOOP SANDING DISC
See Figure 3, page 13.
To attach hook and loop sanding disc:
 Unplug the 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 recom-
mend that you clean the backing pad and the sanding
disc backing occasionally by brushing them lightly with
a small brush.
SELECTING THE ORbIT DIAMETER
See Figure 4, page 13.
The dual random orbit selector allows you to choose
between two orbits: the 1/8 in. orbit setting produces a
finer surface finish, while the 1/4 in. orbit setting increases
the removal rate.
With the sander held in normal operating position, the dual
random orbit selector should be positioned to the left of the
switch trigger for a 1/4 in. orbit diameter. The dual random
orbit selector should be positioned to the right of the switch
trigger for a 1/8 in. orbit diameter.
VARIAbLE SPEED DIAL
See Figure 5, page 13.
The variable speed dial allows the sander to operate at
speeds that can be adjusted by rotating the dial from A to F.
The dial is conveniently located on the motor housing, allow-
ing operator control of disc speed. To increase sanding disc
speed, turn the variable speed dial to a higher setting. Turn
dial to a lower setting to decrease sanding disc speed.
Recommended speed settings are as follows:
Speed Surface/Application
A - B plastic, plexiglass
C - D metal finishing, old paint removal
E - F wood/coarse and fine sanding
ATTACHING THE DUST bAG
See Figure 6, page 13.
The dust bag provides a dust collection system for the
sander. Sanding dust is drawn up through the holes of
the sanding disc and collected in the dust bag during
sanding.
To attach the dust bag:
 Unplug the sander.
 Slide dust bag assembly onto blower exhaust turning
clockwise to tighten.
ATTACHING THE SANDER TO A VACUUM
See Figure 7, page 14.
To attach the sander to a vacuum:
 Unplug the sander.
 Turn the dust bag counterclockwise to remove from
sander.
 Attach the vacuum hose to the vacuum adaptor.
WARNING
When sander is not connected to vacuum, always
install dust bag back on sander. Failure to do so
could cause sanding dust or foreign objects to be
thrown into the face or eyes which could result in
possible serious injury.
NOTE: A standard 1-1/4 in. vacuum hose fits inside the
smaller diameter hole inside the dust exhaust, while a stan-
dard 2-1/2 in. vacuum hose connection fits inside the larger
hole of the dust exhaust.
TURNING THE SANDER ON/OFF
See Figure 8, page 14.
Depress the switch trigger to turn the sander ON. Release
the switch trigger to turn the sander OFF.
LOCkING ON THE SANDER
See Figure 8, page 14.
The sander is equipped with a lock-on feature, which is
convenient for continuous sanding for extended periods
of time.
WARNING:
Before connecting the sander to a power supply,
make sure it is not in the locked-on position. Failure
to do so could result in accidental starting of the
tool resulting in serious injury.
To lock on the sander:
 Depress the switch trigger.
 Push in the lock-on button.
 Release the switch trigger.
 Release the lock-on button.
