• Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop 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 accessory may fly away and cause injury beyond
immediate area of operation
• 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
• 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
• 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
NOTE: The above warning does not apply for power tools specifically designed for use with a liquid system
Further safety 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 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 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
• 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
• Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and
loss of control
Additional safety instructions for polishing operations
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
