G8793 12" Double Disc Sander -13-
SECTION 6: OPERATIONS
The cast iron disc accepts 12" diameter cloth or
paper-backed PSA sanding discs. These are
available in a variety of grits. See the current
Grizzly catalog for prices and ordering informa-
tion.
Please review all safety rules for sanders and all
power tools before attempting operation. The
hints listed below are also worth your considera-
tion:
1. When using the table for beveled sanding
operations, try to keep an open table angle
(90˚ or more). This eliminates the risk of
getting the workpiece jammed between the
disc and the table.
2. The surface feet per minute of the spinning
disc increases as you move from the center
to the rim.
3. Do not over-sand soft woods such as bass
wood or pine.
4. Choose the correct sanding grit for the job.
5. Do not use the sander as a replacement for
a bandsaw or a planer. It is designed for fin-
ish work, not rough dimensioning.
6. Keep your workpiece moving across the
face of the disc to prevent grooves or ruts in
the surface you’re sanding.
The disc table can go from -45˚ to 45˚ relative to
the plane of the sanding surface.
Whenever possible, sand with an open angle
where there is plenty of clearance between the
belt and the table. This will avoid getting the work-
piece trapped between the sanding surface and
the table.
Table Tilt
Rotating sanding discs are dangerously
abrasive. Use extreme caution when work-
ing near sanding surfaces. Failure to exer-
cise care while sanding could result in
severe injury.
Operating this equipment has the potential
to propel debris into the air which can
cause eye injury. Always wear safety glass-
es or goggles when operating equipment.
Everyday glasses or reading glasses only
have impact resistant lenses, they are not
safety glasses. Be certain the safety glass-
es you wear meet the appropriate stan-
dards of the American National Standards
Institute (ANSI).
