3) 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 incor-
rect operating procedures or conditions and can
be avoided by taking proper precautions as given
below.
a) 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.
b) 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 kick-
back may drag your fingers into the saw blade.
c) 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.
d) Align the fence to be parallel with the saw
blade. A misaligned fence will pinch the
workpiece against the saw blade and create
kickback.
e) 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.
f) Use extra caution when making a cut into blind
areas of assembled workpieces. The
protruding saw blade may cut objects that can
cause kickback.
g) Support large panels to minimise 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.

h) Use extra caution when cutting a workpiece
that is twisted, knotted, warped or does not
have a straight edge to guide it with a mitre
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.
i) Never cut more than one workpiece, stacked
vertically or horizontally. The saw blade could
pick up one or more pieces and cause kickback.
j) 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.
k) Keep saw blades clean, sharp, and with suffi-
cient 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.
4) Table saw operating procedure warnings
a) Turn off the table saw and disconnect the
power cord when removing the table insert,
changing the saw blade or making adjustments
to the riving knife, or saw blade guard, and
when the machine is left unattended.
Precautionary measures will avoid accidents.
b) 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.
c) 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.
d) Frequently clean and remove sawdust from
under the saw table and/or the dust collection
device. Accumulated sawdust is combustible
and may self-ignite.
e) The table saw must be secured. A table saw
that is not properly secured may move or tip
over.
f) Remove tools, wood scraps, etc. from the table
before the table saw is turned on. Distraction or
a potential jam can be dangerous.
g) Always use saw blades with correct size and
shape (diamond versus round) of arbour holes.
