j. Hold the power tool only by the insulated
gripping surfaces when performing an
operation where the sanding tool may
contact hidden wiring or its own power
cord. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and
shock the operator.
k. 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.
l. 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.
m. 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.
n. 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.
o. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
p. 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
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.

►
a. 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 maximum
control over kickback or torque reaction
during start-up. The operator can control
torque reactions or kickback forces, if proper
precautions are taken.
b. Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c. 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.
d. 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.
e. 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 sanding
operations:
a. When sanding, do not use excessively
oversized sanding disc paper. Follow the
manufacturers' recommendations
selecting sanding paper. Larger sanding
paper extending beyond the sanding pad
presents a laceration hazard and may cause
snagging, tearing of the disc, or kickback.
Safety warnings specific for polishing
operations
Do not allow any loose portion of the
polishing bonnet or its attachment strings
to spin freely. Tuck away or trim any loose
attachment strings. Loose and spinning
attachment strings can entangle your fingers or
snag on the workpiece.
