Workpiece Inspection; Non-Through & Through Cuts - Grizzly G0623X Owner's Manual

Workpiece
Inspection
Some workpieces are not safe to cut on this
machine or may need to be modified before they
can be safely cut. Before cutting, inspect all
workpieces for the following:
• Material Type: This machine is intended for
cutting natural and man-made wood prod-
ucts, laminate-covered wood products, and
some plastics. Cutting drywall or cementi-
tious backer board creates extremely fine
dust and may reduce the life of the motor
bearings. This machine is NOT designed to
cut metal, glass, stone, tile, etc.; cutting these
materials with a table saw greatly increases
the risk of injury and damage to the saw or
blade.
Foreign Objects: Nails, staples, dirt, rocks
•
and other foreign objects are often embed-
ded in wood. While cutting, these objects
can become dislodged and hit the operator,
cause kickback, 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 kickback and
machine 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 unneces-
sary wear on the blades, increases the risk of
kickback, and yields poor results.
Excessive Warping: Workpieces with exces-
•
sive cupping, bowing, or twisting are danger-
ous to cut because they are unstable and
may move unpredictably when being cut.
• Minor Warping: Slightly cupped workpieces
can be safely supported with cupped side
facing the table or fence; however, work-
pieces supported on the bowed side will rock
during the cut, which could cause kickback.

Non-Through &
Through Cuts
Non-Through Cuts
A non-through cut is a sawing operation where
the blade does not protrude above the top face of
the wood stock, as shown in the Figure below.
Figure 53. Example of a non-through cut.
Examples of non-through cuts include dadoes
and rabbets. Non-through cuts have a higher
risk of injury from kickback because the blade
guard must be removed. However, the riving knife
MUST be installed because it still provides some
protection.
IMPORTANT: When making non-through cuts
with a dado blade, do not attempt to cut the full
depth in one pass. Instead, take multiple light
passes to reduce the load on the blade.
A dado blade smaller than 10" will require removal

workpiece is completely sawn through, as shown
in the Figure below. Examples of through cuts are
rip cuts, cross cuts, miter cuts, and beveled cuts.
The blade guard assembly MUST be used when
performing through cuts.
