Kickback and related warnings
Kickback is a sudden reaction to a
pinched or snagged rotating wheel, back-
ing pad, brush or any other accessory.
Pinching or snagging causes rapid 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 to-
ward or away from the operator, depend-
ing 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 with both
hands on the power tool and
position your body and arms
to allow you to resist kickback
forces. The operator can control
torque reactions or kickback forces, if
proper precautions are taken.
• Use special care when work-
ing 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 toothed saw
blade. Such blades create frequent
kickback and loss of control.
• Always feed the bit into the
material in the same direction
as the cutting edge is exiting
from the material (which is the
same direction as the chips are
thrown). Feeding the tool in the
wrong direction causes the cutting
edge of the bit to climb out of the work
and pull the tool in the direction of this
feed.
• Always clamp the workpiece
firmly when using rotary files,
cutting discs, high-speed milling
tools or carbide milling tools.
These wheels will grab if they become
slightly canted in the groove, and can
kickback. When a cut-off wheel grabs,
the wheel itself usually breaks. When a
rotary file, high-speed cutter or tungsten
carbide cutter grabs, it may jump from
the groove and you could lose control
of the tool.
Safety warnings specific for
grinding and abrasive cutting-off
operations
• Use only wheel types that are
recommended for your power
tool and only for recommended
applications. For example: do
not grind with the side of a cut-
off wheel. Abrasive cut-off wheels
are intended for peripheral grinding,
side forces applied to these wheels
may cause them to shatter.
• For threaded abrasive cones
and plugs use only undamaged
wheel mandrels with an unre-
lieved shoulder flange that are
of correct size and length. Proper
mandrels will reduce the possibility of
breakage.
