their rated speed can break and fly apart.
WARNING: Accessories must be within the capacity rating
marked on the tool. Incorrectly sized accessories cannot be adequately

When starting the tool (with a new or replacement wheel installed)
hold the tool in a well protected area. If the wheel has an undetected
crack or flaw, it should burst in less than one minute. Never start tool
with a person in line with the wheel. This includes the operator.

OPERATION

WARNING: To reduce the risk of injury, turn unit off and
disconnect it from power source before installing and removing
accessories, before adjusting or when making repairs. An
accidental start-up can cause injury.
WARNING: Always observe the safety instructions and applicable
regulations.
WARNING: Grasp tool firmly with both hands to maintain
control of the tool at start up and during use and until the
wheel or accessory stops rotating. Make sure the wheel has
come to a complete stop be fore laying the tool down.
Put the work in a vise or clamp it securely. Use a face mask over the
nose and mouth if the operation raises dust. Treat the wheel with
respect. Do not jam the wheel into the work or use unnecessary
pressure. Grind only on the edge of the wheel (Fig. 2), unless you
have a special wheel specifically made to permit grinding on the face
of the wheel.

such as the activation of a ground fault interrupter, throwing of a
circuit breaker, accidental unplugging, or power failure. If the switch is
locked on, the tool will start unexpectedly when it is reconnected.
