Choosing.Sandpaper
There are many types of sanding belts 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.
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.
Ultimately, the type of wood you use and your
stage of finish will determine the best grit types
to install on your sander.

Sanding.Tips
•
Replace coarse grit sandpaper with a finer
grit to achieve a smoother finish.
•
Raise the table a maximum
1
⁄
4
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 second board touching the back end of
the first board.
• Feed boards into the sander at different
places on the conveyor to maximize
sandpaper life and prevent uneven
conveyor belt wear.
• DO NOT sand boards less than 6" long or
less than
1
⁄
8
" thick to prevent damage to
the workpiece and the drum sander.
• Extend the life of the sandpaper by
regularly using a PRO-STIK® cleaning pad
(see
Page.28
).
• 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.
• DO NOT edge-sand boards. This can cause
boards to kick back, causing serious
personal injury. Edge-sanding boards also
can cause damage to the conveyor belt and
sandpaper.
• When sanding workpieces with a bow or
crown, place the high point up (prevents
the workpiece from rocking) and take very
light passes.
• Feed the workpiece at an angle to
maximize stock removal and sandpaper
effectiveness, but feed the workpiece
straight to reduce sandpaper grit scratches
for the finish passes.
