Stock Inspection and
Requirements
• Excessive glue or finish: Sanding
workpieces with excess glue or finish will load
up the abrasive, reducing its usefulness and
lifespan.
• Minimum Stock Dimensions: DO NOT sand
boards less than 9" long, 2" wide, and
1
⁄8" thick
(G1066R/G1066Z) or
1
⁄4" thick (G1079R) to
prevent damage to the workpiece and to
reduce the risk of your hands contacting the
abrasive belt (see Figure 66).

Some workpieces are not safe to sand, or they
may require further preparation before they can
be safely sanded without increasing risk of injury
to the operator or damaging the sanding belt or
the sander.
Before sanding, inspect all workpieces for the
following:
• Material Type: This machine is intended
for sanding natural and man-made wood
products, and laminate-covered wood prod-
ucts. This machine is NOT designed to sand
glass, stone, tile, plastics, drywall, cemen-
tious backer board, metal, etc.
Sanding metal objects can increase the risk
of fire. Sanding improper materials increases
the risk of respiratory harm to the operator
and bystanders due to the especially fine
dust inherently created by all types of sand-
ing operations—even if a dust collector is
used. Additionally, the life of the machine
and sanding belts may be greatly reduced
(or immediately damaged) from sanding
improper materials.
• Foreign Objects: Tramp metal, nails,
staples, dirt, rocks and other foreign objects
are often embedded in wood. While sanding,
these objects can become dislodged and
tear the sanding belt. Always visually inspect
your workpiece for these items. If they can't
be removed, DO NOT sand the workpiece.
• Wet or "Green" Stock: Sanding wood with
a moisture content over 20% causes unnec-
essary clogging and wear on the sanding
belt, increases the risk of kickback, and
yields poor results.
• Excessive Warping: Workpieces with
excessive cupping, bowing, or twisting are
dangerous to sand because they are unsta-
ble and often unpredictable when being
sanded. DO NOT use workpieces with these
characteristics!
Choosing Sandpaper
There are many types of sandpaper rolls to
choose from. We recommend Aluminum Oxide for
general workshop environments. Below is a chart
that groups abrasives into different classes, and
shows which grits fall into each class.

and glue removal.
60 Coarse Thickness sanding
and glue removal.
80 –100 Medium Removing planer
