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 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 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
150mm, and use a push block when
this distance is less than 50mm.
“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 mitre 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 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 2mm 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
