TABLE SAW SAFETY RULES
KICKBACK CAUSES AND RELATED WARNINGS
Kickback is a sudden reaction of the workpiece due to a
pinched, jammed saw blade or misaligned line of cut in the
workpiece with respect to the saw blade or when a part of
the workpiece binds between the saw blade and the rip
fence or other fixed object.
Most frequently during kickback, the workpiece is lifted from
the table by the rear portion of the saw blade and is propelled
towards the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
Never stand directly in line with the saw blade. Always
position your body on the same side of the saw blade
as the fence. Kickback may propel the workpiece at high
velocity towards anyone standing in front and in line with
the saw blade.
Never reach over or in back of the saw blade to pull or
to support the workpiece. Accidental contact with the
saw blade may occur or kickback may drag your fingers
into the saw blade.
Never hold and press the workpiece that is being
cut off against the rotating saw blade. Pressing the
workpiece being cut off against the saw blade will create
a binding condition and kickback.
Align the fence to be parallel with the saw blade. A
misaligned fence will pinch the workpiece against the
saw blade and create kickback.
Use a featherboard to guide the workpiece against the
table and fence when making non-through cuts such
as rabbeting, dadoing or resawing cuts. A featherboard
helps to control the workpiece in the event of a kickback.
Use extra caution when making a cut into blind areas
of assembled workpieces. The protruding saw blade
may cut objects that can cause kickback.
Support large panels to minimize the risk of saw blade
pinching and kickback. Large panels tend to sag under
their own weight. Support(s) must be placed under all
portions of the panel overhanging the table top.
Use extra caution when cutting a workpiece that is
twisted, knotted, warped or does not have a straight
edge to guide it with a miter gauge or along the fence.
A warped, knotted, or twisted workpiece is unstable
and causes misalignment of the kerf with the saw blade,
binding and kickback.
Never cut more than one workpiece, stacked vertically
or horizontally. The saw blade could pick up one or more
pieces and cause kickback.
When restarting the saw with the saw blade in the
workpiece, centre the saw blade in the kerf so that
the saw teeth are not engaged in the material. If the
saw blade binds, it may lift up the workpiece and cause
kickback when the saw is restarted.
Keep saw blades clean, sharp, and with sufficient
set. Never use warped saw blades or saw blades with
cracked or broken teeth. Sharp and properly set saw
blades minimise binding, stalling and kickback.
TABLE SAW OPERATING PROCEDURE WARNINGS
Turn off the table saw and unplug the tool when
removing the table insert, changing the saw blade or
making adjustments to the riving knife, anti-kickback
pawls or blade guard, and when the machine is left
unattended. Precautionary measures will avoid accidents.
Never leave the table saw running unattended. Turn it
off and don’t leave the tool until it comes to a complete
stop. An unattended running saw is an uncontrolled
hazard.
Locate the table saw in a well-lit and level area where
you can maintain good footing and balance. It should
be installed in an area that provides enough room to
easily handle the size of your workpiece. Cramped,
dark areas, and uneven slippery floors invite accidents.
Frequently clean and remove sawdust from under
the saw table and/or the dust collection device.
Accumulated sawdust is combustible and may self-ignite.
The table saw must be secured. A table saw that is not
properly secured may move or tip over.
Remove tools, wood scraps, etc. from the table before
the table saw is turned on. Distraction or a potential jam
can be dangerous.
Always use saw blades with correct size and shape
(diamond versus round) of arbour holes. Saw blades
that do not match the mounting hardware of the saw will
run off-centre, causing loss of control.
Never use damaged or incorrect saw blade mounting
means such as flanges, saw blade washers, bolts or
nuts. These mounting means were specially designed for
your saw, for safe operation and optimum performance.
Never stand on the table saw, do not use it as a
stepping stool. Serious injury could occur if the tool is
tipped or if the cutting tool is accidentally contacted.
Make sure that the saw blade is installed to rotate
in the proper direction. Do not use grinding wheels,
wire brushes, or abrasive wheels on a table saw.
Improper saw blade installation or use of accessories
not recommended may cause serious injury.
