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 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 Specific 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 and sparks that could
ignite clothing.
• 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 Warnings Specific
for Abrasive 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 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.
