KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or
snagged rotating wheel or any other accessory.
Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the un-
controlled power tool to be forced in 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 power 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 auxilia-
ry handle, if provided, for maximum control
over kickback or torque reaction during
start-up. The operator can control torque re-
actions or kickback forces, if proper precau-
tions 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 op-
posite to the wheel's movement at the point of
snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and snag-
ging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotating
accessory and cause loss of control or kick-
back.
e) Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades cre-
ate 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 maxi-
mum safety, so the least amount of wheel
is exposed towards the operator. The guard
helps to protect the operator from broken wheel
fragments, accidental contact with wheel and
sparks that could ignite clothing.
c) Wheels must be used only for recommend-
ed 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 se-
lected 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 ex-
cessive 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 operation, is moving away from
your body, the possible kickback may propel the
spinning wheel and the power tool directly at
you.
