Sanding Tips

WARNING: 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.
WARNING: DO NOT sand more than one
board at a time side by side. Minor variations
in thickness can cause one board to be pro-
pelled by the rapidly spinning sanding drum
and ejected from the machine.
WARNING: NEVER stand directly in front
of the infeed area of the machine. Failure to
do so could result in severe personal injury.
NOTICE: Overloading the motor or pushing
the sander to failure weakens the electrical
system. Repeatedly doing so is abuse to the
machine that will cause motor, capacitor, or
circuit breaker damage, which is not covered
under warranty.
NOTICE: DO NOT sand boards less than 9"
long or less than
1
to the workpiece and the drum sander.
NOTICE: Sanding workpieces with high-
resin content or with applied finishes can
quickly contaminate 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 drum a maximum of
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-

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.
