4. Upon completion of sanding operation, turn sander off and wait until sanding disc comes
to a complete stop before removing from workpiece.
5. 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 sanding disc, then turn sander on and run it free without a load (off the workpiece)
to cool the motor.
SANDING TIPS
1. DO NOT force the sander. The weight of the sander"supplies adequate pressure on
the workpiece. Let the sander and the sandpaper's grit do the work.
Applying additional pressure will only slow down the motor, wear the sandpaper
out faster and reduce the sander's orbitalspeed.
Excessive pressure will overload the motor and cause possible damage to the
sander from the motoroverheating.
Excessive pressure will also result in a poor quality finish.
2. Any existing finish or resin on wood may soften from the heat of the friction and cause
the sandpaper to load-up faster.
3. Inspect sandpaper frequently and change paper when grit is worn and not able to
perform properly.
4. DO NOT sand in one spot for too long a time because tlnesander's rapid action may
remove too much material and make the surface uneven.
SELECTING THE RIGHT SANDPAPER
Selecting the correct grit and type of sandpaper is an extremely important decision that
will allow you to achieve the best quality sanding finish.
1. Aluminum oxide, siliconcarbide and other synthetic abrasives are best for power
sanding.
2. Natural abrasives such as flint and garnet are too soft for economical use in power
sanding.
3. Coarse grit will remove the most material and finer grit will give you the best finish in all
sanding operations.
4. The condition of the surface to be sanded will determiine which grit will do the job.
5. If the surface is rough:
Start with a coarse grit and sand until the surface is uniform.
Then use medium to remove any scratches left by the coarse grit.
Then use a finer grit for finishingthe surface.
NOTE: ALWAYS continue sanding with each grit untilthe surface is uniform.
NOTE: DO NOT use the sander without sandpaper. This will damage the cushion.
Z_ WARNING:DO NOT wear loose clothing or jeweh'y when operating sander.
