Stock Inspection &
Requirements
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: Nails, staples, dirt, rocks
•
and other foreign objects are often embed-
ded 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!

Setting Depth of Cut
The optimum depth of cut will vary based on
the type of wood, feed rate, and sandpaper grit.
Attempts to remove too much material can cause
jamming, wood burning, rapid paper wear or tear-
ing, poor finish, and belt slippage.
To set depth of cut:
1.
Rotate
table
(see Figure 15) until conveyor table is well
below sanding drum, then raise table, allow-
ing a gap between workpiece and sanding
drum.
Note: When adjusting table to sand a
thicker workpiece, lower and then raise
table to remove backlash from adjustment
mechanism.

2.
Turn machine ON and feed workpiece into
sander. SLOWLY raise conveyor belt until
workpiece makes light contact with sand-
ing drum. This is the correct height to begin
sanding the workpiece.
3.
After initial pass, turn handwheel up to
(
⁄
" or 0.4mm)—maximum depth for most

sanding conditions.
Note: Each full turn of the table elevation
handwheel raises the conveyor table approxi-
mately 0.060" (
⁄
") or 1.5mm.
