4.2 Safety instructions for sawing
procedures
a) DANGER: Keep fingers and hands
away from cutting area and the blade. A
moment of inattention while operating power tools
or slipping might cause your hand to get near the
saw blade and may result in serious personal
injury.
b) Feed the workpiece into the saw blade
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 mitre gauge to feed the
workpiece for straight cuts and do not use
the ripping fence as a length stop when cross
cutting with the mitre gauge. Guiding the
workpiece with the ripping fence and the mitre
gauge at the same time increases the likelihood
of saw blade binding and kickback.
d) When effecting straight cuts, 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 a push
block when this distance is less than 50 mm.
Such "working aids" ensure that your hand
remains at a safe distance to the saw blade.
e) Use only the supplied push stick of the
manufacturer. The 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 ripping 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
ripping 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.
Long and/or wide workpieces have a tendency to
pivot on the table's edge, causing loss of control,
saw blade binding and kickback.
j) Feed the workpiece at a uniform speed. Do
not bend or twist the workpiece. If the saw
blade jams, immediately switch off the power
tool, pull the mains plug and clear the jam. If
the workpiece causes the jamming of the saw
blade, this could lead to kickback or stalling of the
motor.
k) Do not remove piece of cut-off material
while the saw is running. The material may
become trapped between the saw blade and
fence or in the guard and pull your fingers into the
saw blade. Turn the saw off and wait until the saw
blade stops before removing the material.
I) Use an auxiliary fence for long cuts in
workpieces with a thickness of less than 2
mm. Thin workpieces may wedge under the
fence and create kickback.
4.3 Kickback causes and related warnings
Kickback is a sudden reaction of the workpiece
due to a pinched, bound 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 fence or other
fixed object.
During kickback, in most cases, the workpiece is
lifted off the table by the rear portion of the saw
blade and is propelled towards the operator.
Kickback is the result of incorrect or faulty use of
the table circular saw. It can be prevented if
suitable precautionary measures are taken as
described 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 rail.
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 behind the saw
blade to pull or 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 rail 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 rail when making
hidden cuts (e.g. seaming). A featherboard
helps to control the workpiece in the event of a
kickback.
f) Be particularly careful when sawing in
areas of joined workpieces that you cannot
see. The plunging saw blade can saw into objects
that could cause kickback.
g) Support large panels to minimise the risk
of blade pinching and kickback. Large panels
tend to sag under their own weight. Supports
must be placed under the panel on both sides,
near the line of cut and near the edge of the
panel.
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 rail. 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) If you wish to restart a saw that is stuck in
the workpiece, centre the saw blade in the
kerf and check whether that the saw teeth are
not caught in the workpiece. 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.
4.4 Safety instructions for circular table
saws
a) Turn off the circular table saw and unplug
it when removing the table insert, changing
the saw blade or making adjustments to the
splitting wedge, anti-kickback device or saw
blade guard, and after each completed
cutting procedure. Precautionary measures
serve to avoid accidents.
b) Never leave the circular table saw
unattended when in operation. Turn if off and
don't leave the tool until it has come to a
complete stop. An unattended running saw is an
uncontrolled hazard.
c) Locate the circular table saw in a well lit
and level area where you can maintain good
footing and balance. It should be installed in an
area that provides enough room to easily handle
the size of the workpieces. Cluttered, dark areas,
and uneven slippery floors invite accidents.
d) Regularly clean and remove wood
shavings and saw dust from under the saw
table and/or the dust extraction unit.
Accumulated saw dust is combustible and may
self ignite.
e) Secure the circular table saw. A circular
table saw that is not properly secured may move
or tip over.
f) Remove tools, wood scraps etc. from the
circular table saw before turning it on.
Distraction or possible jams can be dangerous.
g) Always use blades of the right size and
with the appropriate mounting hole (e.g. star-
shaped or round). Blades that do not match the
mounting hardware of the saw will run off-centre,
causing loss of control.
h) Never use damaged or incorrect saw blade
mounting means such as flanges, saw blade
washers, bolts or nuts. These mounting means
were specially designed for your saw, for safe
operation and optimum performance.
i) Never stand on the circular table saw, do
not use it as a stepping stool. Serious injury
could occur if the tool is tipped or if the cutting tool
is accidentally contacted.
j) Make sure that the saw blade is installed to
rotate in the proper direction. Do not use
grinding discs or wire brushes on a circular
table saw. Improper saw blade installation or use
of accessories not recommended may cause
serious injury.
