OPERATION
Do not sand too long in one spot. This will cause uneven
sanding and gouging of the work.
Upon completion of a sanding operation, lift tool away from
work surface before turning off.
WARNING:
Sanding disc must come to a complete stop before
setting tool down on workbench. Failure to do so can
cause the tool to be thrown from workbench because of
sanding disc rotation. This could result in damage to the
tool or possible serious injury to the operator.
SANdING dISC SELECTION
Selecting the correct size grit and type sanding disc 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 garnet 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 the surface.
Always use the proper grit sanding disc, and not extra pres-
sure when sanding. Continue sanding with each grit until
surface is uniform.
