Kickback and Related Warnings – cont’d
For example, if the cutting disc is snagged or
pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into
the surface of the material causing the wheel to
climb out or kick out. The wheel may either jump
toward or away from the operator, depending on
direction of the wheel’s movement at the point of
pinching. Cutting discs may also break under
these conditions.
Kickback is the result of power tool misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking proper
precautions as given below.
Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control
over kickback or torque reaction during
start-up.
The operator can control torque
reactions or kickback forces, if proper
precautions are taken.
Never place your hand near the rotating
accessory.
Accessory may kickback over your
hand.
Do not position your body in the area where
power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite
to the wheel’s movement at the point of
snagging.
Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory.
Corners, sharp
edges or bouncing have a tendency to snag the
rotating accessory and cause loss of control or
kickback.
Do not attach a saw chain woodcarving
blade or toothed saw blade.
Such blades
create frequent kickback and loss of control.
Safety warnings for cutting-off operations
Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel.
Wheels for
which the power tool was not designed cannot
be adequately guarded and are unsafe.
The guard must be securely attached to the
power tool and positioned for maximum
safety, so the least amount of wheel is
exposed towards the operator.
The guard
helps to protect operator from broken wheel
fragments and accidental contact with wheel.
Wheels must be used only for recommended
applications. For example: do not grind
with the side of cut-off wheel.
Abrasive cut-off
wheels are intended for peripheral grinding,
side forces applied to these wheels may cause
them to shatter.
Always use undamaged wheel flanges that
are of correct size and shape for your
selected wheel.
Proper wheel flanges support
the wheel thus reducing the possibility of wheel
breakage. Flanges for cut-off wheels may be
different from grinding wheel flanges.
Do not use worn down wheels from larger
power tools.
Wheel intended for larger power
tool is not suitable for the higher speed of a
smaller tool and may burst.
Additional safety instructions for cutting-off
operations
Do not
″
jam
″
the cut-off wheel or apply
excessive pressure. Do not attempt to make
an excessive depth of cut.
Overstressing the
wheel increases the loading and susceptibility to
twisting or binding of the wheel in the cut and
the possibility of kickback or wheel breakage.
Do not position your body in line with and
behind the rotating wheel.
When the wheel,
at the point of operation, is moving away from
your body, the possible kickback may propel the
spinning wheel and the power tool directly at
you.
When cut-off disc is binding or when
interrupting a cut for any reason, switch off
the power tool and hold the power tool
motionless until the wheel comes to a
complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is
in motion otherwise kickback may occur.
Investigate and take corrective action to
eliminate the cause of wheel binding.
