the riving knife to function properly, the saw blade
diameter must match the appropriate riving knife and
the body of the saw blade must be thinner than the
thickness of the riving knife and the cutting width of the
saw blade must be wider than the thickness of the riving
knife.
2) Cutting procedures warnings
a)
DANGER:
Never place your fingers or hands in the
vicinity or in line with the saw blade. A moment of
inattention or a slip could direct your hand towards the
saw blade and result in serious personal injury.
b) Feed the workpiece into the saw blade or cutter only
against the direction of rotation. Feeding the workpiece
in the same direction that the saw blade is rotating
above the table may result in the workpiece, and your
hand, being pulled into the saw blade.
c) Never use the miter gauge to feed the workpiece when
ripping and do not use the rip fence as a length stop
when cross cutting with the miter gauge. Guiding the
workpiece with 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 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 minimize 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 miter 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, center 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.
