erated by various applications. The dust mask or respir-
ator must be capable of filtrating particles generated by
the particular application. Prolonged exposure to high in-
tensity noise may cause hearing loss.
Keep bystanders a safe distance away from work area.
u
Anyone entering the 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.
Hold the power tool by insulated gripping surfaces
u
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 ex-
posed metal parts of the power tool "live" and could give
the operator an electric shock.
Position the cord clear of the spinning accessory. If
u
you lose control, 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
u
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your con-
trol.
Do not run the power tool while carrying it at your
u
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
u
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 materi-
u
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
u
Using water or other liquid coolants may result in electro-
cution or shock.
Kickback and related warnings:
Kickback is a sudden reaction to a pinched or snagged rotat-
ing wheel, backing pad, brush or any other accessory. Pinch-
ing or snagging causes rapid stalling of the rotating access-
ory 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 direc-
tion of the wheel's movement at the point of pinching. Abras-
ive 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.
Maintain a firm grip with both hands on the power tool
u
and position your body and arms 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 con-

trol torque reactions or kickback forces, if proper precau-
tions are taken.
Never place your hand near the rotating accessory.
u
Accessory may kickback over your hand.
Do not position your body in the area where power
u
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,
u
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, seg-
u
mented diamond wheel with a peripheral gap greater
than 10 mm or toothed saw blade. Such blades create
frequent kickback and loss of control.
Safety warnings specific for grinding and cutting-off
operations:
Use only wheel types that are specified for your power
u
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.
The grinding surface of centre depressed wheels must
u
be mounted below the plane of the guard lip. An im-
properly mounted wheel that projects through the plane
of the guard lip cannot be adequately protected.
The guard must be securely attached to the power tool
u
and positioned for maximum safety, so the least
amount of wheel is exposed towards the operator.
The guard helps to protect the operator from broken
wheel fragments, accidental contact with wheel and
sparks that could ignite clothing.
Wheels must be used only for specified applications.
u
For example: do not grind with the side of cut-off
wheel. Abrasive cut-off wheels are intended for peri-
pheral grinding, side forces applied to these wheels may
cause them to shatter.
Always use undamaged wheel flanges that are of cor-
u
rect size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the pos-
sibility of wheel breakage. Flanges for cut-off wheels may
be different from grinding wheel flanges.
Do not use worn down wheels from larger power tools.
u
A wheel intended for larger power tool is not suitable for
the higher speed of a smaller tool and may burst.
When using dual purpose wheels always use the cor-
u
rect guard for the application being performed. Failure
to use the correct guard may not provide the desired level
of guarding, which could lead to serious injury.
Additional safety warnings specific for cutting-off
operations:
Do not "jam" the cut-off wheel or apply excessive
u
pressure. Do not attempt to make an excessive depth
of cut. Overstressing the wheel increases the loading
