tool to be forced in the direction opposite of
the Accessory's rotation.
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. The
operator can control kickback forces, if
proper precautions are taken.
■ 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 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.
■ When using rotary files, cut-off wheels,
high-speed cutters or tungsten carbide
cutters, always have the workpiece
securely clamped. 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.
Additional safety instructions
for grinding and cutting-off
operations
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 unrelieved shoulder flange that
are of correct size and length. Proper
mandrels will reduce the possibility of
breakage.
■ Do not "jam" a 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
snagging of the wheel in the cut and the
possibility of kickback or wheel breakage.
■ Do not position your hand in line with
and behind the rotating wheel. When
the wheel, at the point of operation, is
moving away from your hand, the possible
kickback may propel the spinning wheel
and the power tool directly at you.
■ When wheel is pinched, snagged 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 pinching or snagging.
■ 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.
