_1_ 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, resulting in possible serious injury. If the sanding operation 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 gamet 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.
Note: Do not use sander without sandpaper, Doing so will damage the cushion.

Hold your sander in front and away from you, keeping it clear of the workpieco. Start your sander by press-
Fig. 4
Do not force. The weight of the unit supplies ad- equate pressure, so let the sandpaper and sander do the work, Applying additional pressure only slows the motor, rapidly wears sandpaper and greatly reduces sander speed. Excessive pressure will overload the motor causing possible damage from motor overheat- ing and can result in infedor 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.
Flush sanding can be performed with your sanden See Figure 5. The front edge of your sander allows flush sanding in corners. Always remove sander from workpleca before turning your sander oft.
_. WARNING: 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,
