EXCHANGEABLE HOOK AND LOOP BASE PADS
This sander includes
interchangeable for different applications.
 Triangular detail pad for detail sanding.
 1/3 sheet pad for sanding large areas.
The hook and loop design allows for quick change of
sanding sheets and different pads. It also enables you to
easily clean and reuse them.
CIRCULAR SANDING ACTION
The oscillating action of your sander produces very quick,
small circular motion of the sanding pad. The motion is
ideal for producing a fi ne fi nished grain.
DUST COLLECTION BOX
The dust collection box attaches to the sander and keeps
dust to a minimum.
VARIABLE SPEED CONTROL
See Figure 4.
Your sander has advanced electronic features, designed
to assist you in getting the maximum use from your sander.
By making proper speed selections, your sander can be
adjusted to specifi c sanding needs.
The variable speed control allows the sander to develop a
no-load speed that can be adjusted from 6,000 to 12,000
min . The variable speed control selector is conveniently

located on the front of the sander.
The electronic feature of your sander introduces the
fl exibility of adjusting the motor speed to required job
conditions. An electronic speed control module senses
the load applied to the motor and increases or decreases
motor voltage to compensate for and maintain desired
RPM. Speed can be set according to the sanding purpose
or the surface of the workpiece you will be using. Increase
speed for rough surfaces or for quick removal of stock and
decrease speed for smaller, delicate sanding applications.
ASSEMBLY
The tool should never be connected to a power supply
when you are assembling parts, making adjustments,
cleaning, performing maintenance, or when the tool is
not in use. Disconnecting the tool will prevent accidental
starting that could cause serious injury.
SANDPAPER SELECTION
Selecting the correct size, grit and type of sand paper is
an extremely important step in achieving a high quality

are
Natural abrasives, such as fl int and garnet are too soft for
economical use in power sanding.
In general, coarse grit will remove the most material
and fi ner grit will produce the best fi nish 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 fi ner grit used for
fi nishing of the surface. Always continue sanding with
each grit until surface is uniform.
Do not use sander without sandpaper; doing so will
damage the cushion.

ATTACHING HOOK AND LOOP SANDING DISCS
See Figure 2.
1. Unplug the sander.
2. Align holes in hook and loop type sanding disc with
holes in pad, then carefully press fuzzy side of sanding
disc against pad as tightly as possible.
NOTE: Hook and loop type sanding discs can be reused
for the life of the sanding abrasive. It is recommended that
you keep the sanding disc backing pad clean to provide for
best adhesion. Clean occasionally by brushing lightly with
a small brush.
ATTACHING THE DUST COLLECTION BOX
See Figure 3.
The dust collection box 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 collection box
during sanding.
1. Unplug the sander.
2. Using a slight twisting motion, fi rmly slide the dust
collection box assembly in the blower exhaust on the
sander.
