Workpiece Inspection - Grizzly G0514X Owner's Manual

Workpiece
Inspection
some wood workpieces are not safe to cut or may
require modification before they are safe to cut.
Before cutting wood, get in the habit of
inspecting all workpieces for the following:
• Material Type: this machine is intended for
cutting natural and man-made wood products,
and laminate covered wood products. Cutting
drywall or cementitious backer board creates
extremely fine dust, which may reduce the
life of the bearings. this machine is not
designed to cut metal, glass, stone, tile, etc.
• foreign Objects (figure 67): nails, staples,
dirt, rocks and other foreign objects are often
embedded in wood. While cutting, these
objects can become dislodged and hit the
operator or break the blade, which might
then fly apart. always visually inspect your
workpiece for these items. if they can't be
removed, do not cut the workpiece.
• Large/Loose Knots: loose knots can
become dislodged during the cutting opera-
tion. large knots can cause blade damage.
Choose workpieces that do not have large/
loose knots or plan ahead to avoid cutting
through them.
• Wet or "Green" Stock: Cutting wood with
a moisture content over 20% causes unnec-
essary wear on the blade and yields poor
results.
• Excessive Warping: Workpieces with exces-
sive cupping, bowing, or twisting are danger-
ous to cut because they are unstable and can
move unpredictably when being cut. do not
cut excessively warped wood.
Minor Warping: Workpieces with slight cup-
•
ping can be safely supported if the cupped
side faces the table or fence, as shown in
figure 68. on the contrary, a workpiece sup-
ported on the bowed side will rock during a
cut, leading to loss of control.

Because of its unpredictable nature, use
extreme caution if cutting warped stock. The
difference between acceptable and unac-
ceptable warped stock varies from machine
to machine. If you are in doubt, square-up
the stock first or do not cut it.
