OPERATION

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 re-

sulting in possible serious injury. If the sanding operating

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 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.

Sheet/Pad Recommended Use

Heavy scrubbing pad Paint and rust removal

Light scrubbing pad Light scrubbing and cleaning

Polishing pad Light cleaning and polishing

60-grit sandpaper Coarse sanding

120-grit sandpaper Light sanding

240-grit sandpaper Finish sanding

ATTACHING HOOK-AND-LOOP SANDPAPER

See Figure 3, page 12.

Unplug the sander.

Align holes in hook-and-loop type sandpaper with holes in

pad, then carefully press fuzzy side of sandpaper against

pad as tightly as possible.

NOTE: Hook-and-loop type sandpaper can be reused for

the life of the sanding abrasive. It is recommended that

you keep the sandpaper backing pad clean to provide

for best adhesion. Clean occasionally by brushing lightly

with a small brush.

CAUTION:

Keep the cord away from the sanding pad and position

the cord so that it will not be caught on lumber, tools, or

other objects during sanding.

TURNING THE SANDER ON/OFF

See Figure 4, page 12.

 Turn on the sander: Push the ON/OFF switch to the

left.

 Turn off the sander: Push the ON/OFF switch to the

right.

CAUTION:

Be careful not to let your hand completely cover air

vents.

OPERATING THE SANDER

See Figures 5 - 6, page 12.

 Secure the workpiece to prevent it from moving under

the sander.

WARNING:

Unsecured work could be thrown towards the operator

causing injury.

 Place the sander on the workpiece so that all of the sand-

ing disc surface is in contact with the workpiece.

 Turn the sander on and move it slowly over the

workpiece.

Hold the 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 the sander onto the

workpiece. Move the sander slowly across the workpiece

using small circular motions. See Figure 5.

Do not force. The weight of the unit supplies adequate

pressure, so let the sanding disc and sander do the work.

Applying additional pressure only slows the motor, rapidly

wears sanding disc 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. Do not allow sanding 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 tend to overheat the motor.

If this occurs, turn sander off and wait until sanding disc

comes to a complete stop, then remove it from workpiece.

Remove your hand from vent area, remove sanding disc,

then with your hand removed from vent area, turn sander

on and run it free without a load to cool motor.

For detail sanding such as corners and crevices, use the tip

of the sanding pad with small back and forth motions, as

shown in figure 6.
