blade. Pressing the workpiece being cut
off against the saw blade will create a
binding condition and kickback.
• Align the fence to be parallel with the saw
blade. A misaligned fence will pinch the
workpiece against the saw blade and
create kickback.
• 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.
• Use extra caution when making a cut into
blind areas of assembled workpieces. The
protruding saw blade may cut objects that
can cause kickback.
• 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.
• 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.
• Never cut more than one workpiece,
stacked vertically or horizontally. The saw
blade could pick up one or more pieces
and cause kickback.
• 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.
• 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
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.
• 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.
• 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 incorrect operating procedures or
conditions and can be avoided by taking proper
precautions as given below.
• 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.
• 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.
• Never hold and press the workpiece that is
being cut off against the rotating saw
