Power Tool-Specific Safety Warnings
k. Hold the power tool by insulated grip-
ping surfaces only, when performing an
operation where the cutting accessory
may contact hidden wiring. Contact with a
"live" wire will also make exposed metal
parts of the power tool "live" and could
give the operator an electric shock.
l. Always hold the tool firmly in your
hand(s) during the start-up. The reaction
torque of the motor, as it accelerates to full
speed, can cause the tool to twist.
m. Use clamps to support workpiece whenev-
er practical. Never hold a small workpiece
in one hand and the tool in the other hand
while in use. Clamping a small workpiece
allows you to use your hand(s) to control
the tool. Round material such as dowel
rods, pipes or tubing have a tendency to
roll while being cut, and may cause the bit
to bind or jump toward you.
n. Never lay the power tool down until the
accessory has come to a complete stop.
The spinning accessory may grab the
surface and pull the power tool out of your
control.
o. After changing the bits or making any
adjustments, make sure the collet nut,
chuck or any other adjustment devices
are securely tightened. Loose adjustment
devices can unexpectedly shift, causing
loss of control, loose rotating components
will be violently thrown.
p. Do not run the power tool while carrying
it at your side. Accidental contact with the
spinning accessory could snag your cloth-
ing, pulling the accessory into your body.
q. Regularly clean the power tool's air vents.
The motor's fan will draw the dust inside
the housing and excessive accumulation
of powdered metal may cause electrical
hazards.
r. Do not operate the power tool near flam-
mable materials. Sparks could ignite these
materials.
s. Do not use accessories that require liquid
coolants. Using water or other liquid cool-
ants may result in electrocution or shock.

2. 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 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 move-
ment 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 con-
ditions 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. The operator can
control kickback forces, if proper precau-
tions are taken.
b. 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 kickback.
c. Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.
d. 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.
e. When using rotary files, high-speed cut-
ters or tungsten carbide cutters, always
have the work securely clamped. These
wheels will grab if they become slightly
canted in the groove, and can kickback.
When a rotary file, high-speed cutter or
