Basic Sanding Operation
Sandpaper Selection
Selecting the correct size diameter, cor- rect size grit, and correct type sandpaper is an extremely important step in achiev- ing a high quality sanded finish. Aluminum oxide, silicon carbide, and other synthetic abrasives are best for power sanding. Natural abrasives, such as flint and gar- net, 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 sand- paper. Doing so will damage the rubber drum.
Select and install the desired sanding sleeve for your particular application. Sanding sleeves from 1/2" to 2" can be used with this sander. Choose one that is close in size to the workpiece you are sanding. Also install the appropriate spacer ring insert (page 15).
WARNING: Failure to use the cor- rect size spacer ring insert with its matching sanding sleeve could result in fingers being pinched or the workpiece being pulled down between the spacer ring insert and sanding sleeve.
NOTE: The correct size sanding belt is 4" x 24". These belts are available in coarse, medium and fine grits.
