c. Never use the mitre gauge to feed the work-
piece when ripping and do not use the rip
fence as a length stop when cross cutting with
the mitre gauge. Guiding the workpiece with
the rip fence and the mitre gauge at the same
time increases the likelihood of saw blade
binding and kickback.
d. When ripping, always apply the 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 man-
ufacturer or constructed in accordance with
the instructions. This push stick provides suf-
ficient distance of the hand from the saw blade.
f. Never use a damaged or cut push stick. A
damaged 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 sup-
port 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 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 2 mm
thick. A thin workpiece may wedge under the
rip fence and create a kickback.
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 in-
correct 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.
