workpiece feeding force between the fence and
the saw blade. Use a push stick when the distance
between the fence and the saw blade is less than 150
mm, and use a push block when this distance is less
than 50 mm. "Work helping" devices will keep your hand
at a safe distance from the saw blade.
e ) Use only the push stick provided by the
manufacturer or constructed in accordance with the
instructions. This push stick provides sufficient distance
of the hand from the saw blade.
f ) Never use a damaged or cut push stick. A damaged
or cut push stick may break causing your hand to slip into
the saw blade.
g ) Do not perform any operation "freehand". Always
use either the rip fence or the mitre gauge to position
and guide the workpiece. "Freehand" means using
your hands to support or guide the workpiece, in lieu
of a rip fence or mitre gauge. Freehand sawing leads to
misalignment, binding and kickback.
h ) Never reach around or over a rotating saw blade.
Reaching for a workpiece may lead to accidental contact
with the moving saw blade.
i ) Provide auxiliary workpiece support to the rear
and/or sides of the saw table for long and/or wide
workpieces to keep them level. A long and/or wide
workpiece has a tendency to pivot on the table's edge,
causing loss of control, saw blade binding and kickback.
j ) Feed the workpiece at an even pace. Do not bend,
twist or shift the workpiece from side to side. 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 2 mm 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 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, 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.
