Sanding Tips
•
DO NOT edge sand boards. This can cause
boards to kickback, causing serious personal
injury. Edge sanding boards also can cause
damage to the conveyor belt and sandpaper.
•
DO NOT sand more than one board at a time
side by side. Minor variations in thickness
can cause one board to be propelled by the
rapidly spinning sanding drum and ejected
from the machine.
•
NEVER stand directly in front of the infeed
area of the machine. Failure to do so could
result in severe personal injury.
•
DO NOT sand boards less than 9" long, 2"
wide, and
⁄
" thick (G1066R/G1066Z) or
1
8
thick (G1079R) to prevent damage to the
workpiece and to reduce the risk of your
hands contacting the abrasive belt.
•
Sanding workpieces with high-resin content
or with applied finishes can quickly contami-
nate sandpaper beyond the point where it can
be properly cleaned. This will produce poor
sanding results. In this case, use a different
workpiece, remove the applied finishes, or
frequently clean/replace the sandpaper strip.
Replace coarse grit sandpaper with a finer
•
grit to achieve a smoother finish.
Lower the conveyor table a maximum of
•
turn of the handwheel until the workpiece is
the desired thickness.
•
Reduce snipe when sanding more than one
board of the same thickness by feeding them
into the sander with the front end of the sec-
ond board touching the back end of the first
board.
•
Feed boards into the sander at different plac-
es on the conveyor to maximize sandpaper
life and prevent uneven conveyor belt wear.
•
Extend the life of the sandpaper by regu-
larly using a PRO-STIK

•
Run wide stock through two or three times
without adjusting table height. Turn stock
180° between passes to ensure an evenly
sanded surface.
•
When sanding workpieces with irregular
surfaces, such as cabinet doors, take very
light sanding passes to prevent gouges.
When the drum moves from sanding a wide
surface to sanding a narrow surface, the load
on the motor will be reduced, and the drum
will speed up, causing a gouge.
•
When sanding workpieces with a bow or
crown, place the high point up or cupped side
down to prevent the workpiece from rocking
and take very light passes.
•
Feed the workpiece at an angle to maxi-
mize stock removal and sandpaper effec-
tiveness, but feed the workpiece straight to
reduce sandpaper grit scratches for the finish
passes.
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.
Grit
Class
36
Extra Coarse Rough sawn boards,

Coarse
80–100
Medium
120–180 Fine
The general rule of thumb is to sand a workpiece
with progressively higher grit numbers, with no
one grit increase of more than 50. Avoid skipping
grits; the larger the grit increase, the harder it will
be to remove the scratches from the previous grit.
