SAFETY INFORMATION
• Wheels must be used only for recommended applications. For example: do not grind
with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding,
side forces applied to these wheels may cause them to shatter.
• Always use undamaged wheel flanges that are of correct diameter for your selected
wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel
breakage.
• 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 arbour size of wheels and flanges must properly fit the spindle of the power
tool. Wheels and flanges with arbour 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. Cutting accessory
contacting a "live" wire may make exposed metal parts of the power tool "live" and could
give the operator an electric shock.
• 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.

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.
