 Hold the power tool by insulated gripping sur-
faces only, when performing an operation
where the cutting accessory may contact hid-
den wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed met-
al parts of the power tool "live" and could give
the operator an electric shock.
 Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled in-
to the spinning wheel.
 Never lay the power tool down until the acces-
sory has come to a complete stop. The spin-
ning wheel may grab the surface and pull the
power tool out of your control.
 Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
 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.
 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, backing pad, brush or
any other accessory. Pinching or snagging caus-
es rapid stalling of the rotating accessory which
in turn causes the uncontrolled power tool to be
forced in the direction opposite of the accesso-
ry'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 power tool misuse
and/or incorrect operating procedures or condi-
tions and can be avoided by taking proper pre-
cautions as given below.
 Maintain a firm grip on the power tool and po-
sition your body and arm to allow you to resist

kickback forces. Always use auxiliary handle,
if provided, for maximum control over kick-
back or torque reaction during start-up. The
operator can control torque reactions or kick-
back forces, if proper precautions are taken.
 Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
 Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back will propel the tool in direction opposite to
the wheel's movement at the point of snagging.
 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 saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety warnings specific for Grinding
and Abrasive Cutting-Off operations
 Use only wheel types that are recommended
for your power tool and the specific guard de-
signed for the selected wheel. Wheels for
which the power tool was not designed cannot
be adequately guarded and are unsafe.
 The grinding surface of the centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip can-
not be adequately protected.
 The guard must be securely attached to the
power tool and positioned for maximum safe-
ty, so the least amount of wheel is exposed to-
wards the operator. The guard helps to protect
operator from broken wheel fragments, acciden-
tal contact with wheel and sparks that could ig-
nite clothing.
 Wheels must be used only for recommended
applications. For example: do not grind with
the side of the 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 are
of correct 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.
