■ Do not operate the power tool
near flammable materials. Sparks
could ignite these materials.
■ Do not use accessories that
require liquid coolants. Using
water or other liquid coolants may
result in electrocution or shock.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a
pinched or snagged rotating wheel,
sanding band, 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.
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
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
always have the work 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.
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
shoulder flange
correct size and length. Proper
mandrels will reduce the possibility
of breakage.
