When gripping the sander during use, ALWAYS be careful not
to cover the air vents with your hands (see Fig. 9).
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 orbital speed.
• Excessive pressure will overload the motor and cause possible damage to the
sander from the motor overheating.
• 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
4. DO NOT sand in one spot for too long a time because the sander'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, silicon carbide and other synthetic abrasives are best for power
2. Natural abrasives such as flint and garnet are too soft for economical use in power
3. Coarse grit will remove the most material and finer grit will give you the best finish in all
SELECTING THE RIGHT SANDPAPER cont.
4. The condition of the surface to be sanded will determine 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 finishing the surface.
NOTE: ALWAYS continue sanding with each grit until the surface is uniform.
NOTE: DO NOT use the sander without sandpaper. This will damage the cushion.
DO NOT wear loose clothing or jewelry when operating sander.
They could get caught in moving parts, causing serious injury. Keep head away from
sander and sanding area. Hair could be drawn into sander, causing serious injury.
Empty dust bag before storage to help prevent possible fire
hazard, especially when resin coating or linseed oil finishes have been sanded.
NOTE: Empty dust bag frequently when sanding so dust collection system
ORBITAL MOTION (Fig. 10)
As shown in Figure 10, the orbit of the sander is 1/16-in in diameter so the sandpaper
moves in tiny circles at very high speed, allowing the sander to move easily.
This orbital action duplicates a "hand sanding" motion for more aggressive sanding as
you push the sander forward. This powerful orbital action is ideal for heavy-duty sanding
applications, such as:
1. Removing old finishes
2. Smoothing rough wood
3. Sanding stock down to required dimensions
4. Finishing surfaces that are to be painted
