the direction opposite of the accessory’s rotation at
the point of the binding.
For example, if an abrasive wheel 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.
Abrasive wheels may also break under these
conditions.
Kickback is the result of tool misuse and/or incorrect
operating procedures or conditions and can be
avoided by taking proper precautions as given
below:
a)
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 reaction or
kickback forces, if proper precautions are taken.
b)
Never place your hand near the rotating
accessory.
Accessory may kickback over your
hand.
c)
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.
d)
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.
e)
Do not attach a saw chain woodcarving
blade or toothed saw blade.
Such blades
create frequent kickback and loss of control.
Safety Warnings Specific for
Grinding and abrasive cutting-off
operations
a)
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.
b)
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.
c)
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.
d)
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.
e)
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 Warnings Specific
for abrasive cutting-off operations
a)
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.
b)
Do not position your body in line with and
behind the rotating wheel.
When the wheel,
at the point of operations, is moving away from
your body, the possible kickback may propel the
spinning wheel and the power tool directly at
you.
c)
When wheel 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.
d)
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut.
The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
e)
Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback.
Large workpieces tend to sag under
their own weight. Supports must be placed
