WARNING:
Do not allow familiarity with tools to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict serious injury.

BASIC OPERATION Of ThE TABLE SAW
The 3-prong plug must be plugged into a matching outlet
that is properly installed and grounded according to all local
codes and ordinances. Improper connection of the equip-
ment can result in electric shock. Do not modify the plug if
it will not fit the outlet. Have the correct outlet installed by
a qualified electrician. Refer to the Electrical section in this
manual.

CAUSES Of KICKBACK

Kickback can occur when the blade stalls or binds, kicking
the workpiece back toward you with great force and speed. If
your hands are near the saw blade, they may be jerked loose
from the workpiece and may contact the blade. Kickback
can cause serious injury. Use precautions to avoid the risks.
Kickback can be caused by any action that pinches the
blade in the wood such as:
 Making a cut with incorrect blade depth
 Sawing into knots or nails in the workpiece
 Twisting the wood while making a cut
 Failing to support work
 Forcing a cut
 Cutting warped or wet lumber
 Using the wrong blade for the type of cut
 Not following correct operating procedures
 Misusing the saw
 Failing to use the anti-kickback pawls
 Cutting with a dull, gummed-up, or improperly set
blade

AVOIDING KICKBACK

 Always use the correct blade depth setting. The top of
the blade teeth should clear the workpiece by 1/8 in. to
1/4 in.
 Inspect the work for knots or nails before beginning a
cut. Knock out any loose knots with a hammer. Never
saw into a loose knot or nail.
 Always use the rip fence when rip cutting and the miter
gauge when cross cutting. This helps prevent twisting
the wood in the cut.
 Always use clean, sharp, and properly-set blades. Never
make cuts with dull blades.
 To avoid pinching the blade, support the work properly
before beginning a cut.
 When making a cut, use steady, even pressure. Never
force cuts.
 Do not cut wet or warped lumber.
 Always hold your workpiece firmly with both hands or with
push sticks. Keep your body in a balanced position to
be ready to resist kickback should it occur. Never stand
directly in line with the blade.
 Use the right type of blade for the cut being made.
