work area must wear personal protective
equipment. Fragments of workpiece or of a broken
accessory may fly away and cause injury beyond
immediate area of operation.
j) Hold the power tool by insulated gripping
surfaces only, when performing an
operation where the cutting accessory
may contact hidden wiring or its own
cord. Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
k) Position the cord clear of the spinning
accessory. If you lose control, 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.
q) Your hand must hold on the handle when
you are working. Always use the auxiliary
handles supplied with the tool. Loss of
control can cause personal injury.

INSTRUCTIONS FOR ALL
OPERATIONS
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
16
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.

INSTRUCTIONS
FOR GRINDING
AND CUTTING-OFF
OPERATIONS
Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations:
a) Use only wheel types that are
recommended for your power tool and
the specific guard designed for the
selected wheel. Wheels for which the power tool
was not designed cannot be adequately guarded and
are unsafe.
b) The guard must be securely attached
to the power tool and positioned for
