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 and shop apron capable of
stopping small abrasive or workpiece fragments. The eye protection must be cap-able 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
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
