wheel. Proper wheel flanges support the
wheel thus reducing the possibility of wheel
breakage.
Do not use worn down wheels from larger
power tools. Wheel intended for larger power
tool is not suitable for the higher speed of a
smaller tool and may burst.
The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately guarded or
controlled.
The arbor size of wheels and flanges must
properly fit the spindle of the power tool.
Wheels and flanges with arbor holes that do
not match the mounting hardware of the power
tool will run out of balance, vibrate excessively
and may cause loss of control.
Do not use damaged wheels. Before each
use, inspect the wheels for chips and
cracks. If power tool or wheel is dropped,
inspect for damage or install an
undamaged wheel. After inspecting and
installing the wheel, position yourself and
bystanders away from the plane of the
rotating wheel and run the power tool at
maximum no load speed for one minute.
Damaged wheels will normally break apart
during this test time.
Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As
appropriate, wear dust mask, hearing
protectors, gloves and shop apron capable
of stopping small abrasive or workpiece
fragments. The eye protection must be
capable of stopping flying debris generated by
various operations. The dust mask or
respirator must be capable of filtrating particles
generated by your operation. Prolonged
exposure to high intensity noise may cause
hearing loss.
Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken wheel
may fly away and cause injury beyond
immediate area of operation.
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.
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 wheel.
Never lay the power tool down until the
accessory has come to a complete stop.
The spinning 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. Pinching or snagging
causes rapid stalling of the rotating wheel
which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the
wheel'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.
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.
Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
Do not position your body in line with the
rotating wheel. Kickback will propel the tool in
-4-
