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 hint and garnet are too soft tor eco­
nomical use in power sanding. In general, coarse grit will
remove the most material and finer grit wii! 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.
CAUTION: Be careful not to let your hand com­
pletely cover the air vents.
