length stop when cross cutting with the miter gauge. Guiding the workpiece with the rip fence
and the miter 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 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 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 miter 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 miter 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.
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
