Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or any
other accessory. Pinching or snagging causes rap-
id stalling of the rotating accessory which in turn
causes the uncontrolled 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 tool misuse and/or incor-
rect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:
Maintain a firm grip on the power tool and
u
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.
Never place your hand near the rotating
u
accessory. Accessory may kickback over
your hand.
Do not position your body in the area where
u
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,
u
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
u
blade or toothed saw blade. Such blades
create frequent kickback and loss of control.
Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations:
Use only wheel types that are recommended
u
for your power tool and the specific guard
designed for theselected wheel. Wheels for
which the power tool was not designed cannot
be adequately guarded and are unsafe.
The grinding surface of centre depressed
u
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel
that projects through the plane of the guard lip
cannot be adequately protected.
The guard must be securely attached to the
u
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, accidental contact with wheel and
sparks that could ignite clothing.
Wheels must be used only for
u
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
u
are ofcorrect 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
u
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
abrasivecutting-off operations
Do not "jam" the cut-off wheel or apply
u
excessive pressure. Do not attempt to make
an excessive depth of cut. Over stressing 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
u
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
u
a cut for any reason, switch off the power
