Choosing Sandpaper
The Model SB1093 uses a 6" x 48" sanding belt
and a 12" sanding disc.
There are many types of sanding belts and discs
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 grits at a time.
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.

Stock Inspection and
Requirements
stock inspection
Some workpieces are not safe or may require
modification before they are safe to sand.
Before sanding, inspect all workpieces for the
following:
•
Material Type:
This machine is intended for
ONLY sanding natural and man-made wood
products. This machine is NOT designed
to sand metal, glass, stone, tile, drywall or
cementitious backerboard.
•
Foreign Objects:
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.
•
Excessive Glue or Finish:
Sanding workpieces
with excess glue or finish will load up
the abrasive, reducing its usefulness and
lifespan.
Sanding surfaces can cause serious personal
injury if they come in contact with fingers,
hands or other body parts. Use extreme care
to provide a safe distance between the belt
and any part of your body.
Sanding Tips
•
Replace the sandpaper with a higher grit to
achieve a finer finish.
• Extend the life of the sandpaper by regularly
using PRO-STIK® abrasive belt cleaners (see
Accessories
on
Page 33
).
• When sanding workpieces with a bow or
crown, place the high point up on the table to
prevent the workpiece from rocking.
• Hold workpiece securely with both hands.
Use work table to support workpiece.
• Sanding discs/belts clog and wear. Change
sandpaper whenever you notice a difference
in sanding quality/performance.
• To increase the life of the sanding disc/belt
and ensure even wear, move the workpiece
back and forth across the sanding surface.
