APPLICATIONS
You may use this tool for the purposes listed below:
n Sanding wood, metals, plastics, and other materials
n Smoothing rough boards, chamfering, rounding edges, etc.
n Removing rust, paint, varnishes, and stains
SELECTING SANDING BELTS
Selecting the correct size and type of sanding belt is an
important step in achieving a high quality sanded finish.
Aluminum oxide, silicon carbide, and other synthetic abra-
sives are best for power sanding.
In general, when sanding, coarse grit removes the most
material and fine grit produces the best finish. The condi-
tion of the surface to be sanded determines which grit
will do the best job. If the surface is rough, start with a
coarse grit and sand until the surface is uniform. Then use
medium grit to remove scratches left by the coarser grit.
Finally, use finer grit for finishing the surface. Always con-
tinue sanding with each grit until the surface is uniform.
