 Position the cord clear of the spinning
accessory. If you lose control of the power tool,
the cord may be cut or snagged and your hand or
arm may be pulled into the spinning accessory.
 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.
 Do not run the power tool while carrying
it at your side. Accidental contact with the spin-
ning 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 flam-
mable 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 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 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 condi-
tions.
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. Always use
auxiliary handle, if provided, for maxi-
mum control over kickback or torque
reaction during start-up. The operator can
control torque reactions or kickback forces, if
proper precautions are taken.
 Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
 Do not position your body in the area
where power tool will move if kickback
occurs. Kickback 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 kick-
back.
 Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades
create frequent kickback and loss of control over
the power tool.
Safety warnings specific for Grind-
ing and Abrasive Cutting-Off opera-
tions
 Use only wheel types that are recom-
mended for your power tool and the spe-
cific guard designed for the selected
wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are
unsafe.
 The guard must be securely attached to
the power tool and positioned for maxi-
mum safety, so the least amount of wheel
is exposed towards the operator. The
guard helps to protect operator from broken wheel
fragments, accidental contact with wheel and
sparks that could ignite clothing.
 Wheels must be used only for recom-
mended 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 differ-
ent from grinding wheel flanges.
 Do not use worn down wheels from
larger power tools. Wheels intended for larger
power tools are not suitable for the higher speed of
a smaller tool and may burst.
