OPERATION
Selecting the correct size and type sanding beit is an
important step in achieving a high quality sanded
finish. Standard 3 inch x 21 inch sanding belts made
' of alumt'num oxide, silicone carbide, and other synthetic abrasives are best for power sanding, in
general, coarse grit will remove the most material
and fine grit wilt produce the smoothest fintsh in alt
sanding operations. The condition of the surface to
be sanded wtlt determine which grit belt will do the
job, if the surface is rough, start with a coarse grit
belt sanding until surface is uniform Medium grit
belt may then be used to remove scratches left by
the coarser belt and fine grit belt used for finishing
of the surface. Always continue sanding with each
grit belt until the surface is uniform
