causing loss of control, saw blade binding
and kickback.
j) Feed workpiece at an even pace. Do not
bend or twist the workpiece. If jamming
occurs, turn the tool off immediately,
unplug the tool then clear the jam.
Jamming the saw blade by the workpiece
can cause kickback or stall the motor.
k) Do not remove pieces of cut-off material
while the saw is running. The material
may become trapped between the fence
or inside the saw blade guard and the saw
blade pulling your fingers into the saw blade.
Turn the saw off and wait until the saw blade
stops before removing material.
l) Use an auxiliary fence in contact with
the table top when ripping workpieces
less than 2mm thick. A thin workpiece
may wedge under the rip fence and create
a kickback.
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
incorrect 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 kickback 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
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.
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, anti-kickback device 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.
