b)
Feed the workpiece into the saw blade or cut-
ter only against the direction of rotation. Feed-
ing 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 work-
piece when ripping and do not use the rip fence
as a length stop when cross cutting with the mi-
tre 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 making longitudinal cuts, always keep
the workpiece in full contact with the stop
rail and always apply the feed force to the
workpiece between the stop rail and the
saw blade. Use a push stick when the dis-
tance 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 manu-
facturer 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 dam-
aged or cut 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 parallel stop or
mitre gauge. Freehand sawing leads to misalign-
ment, binding and kickback.
h)
Never reach around or over a rotating saw
blade. Reaching for a workpiece may lead to acci-
dental 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,
twist or move the workpiece sideways. If jam-
ming occurs, turn the tool off immediately, un-
plug 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.
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 pre-
cautions 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 pro-
pel 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 kick-
back.
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 re-
sawing 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 kick-
back.
