Motor Overload and Power Loss Reset Switch
If power is interrupted by a circuit breaker trip, or power is lost, the saw contains a power loss
reset switch feature that will automatically reset to OFF position.
Circuit breaker overload is often the result of a dull blade. Change your blade on a regular
basis to avoid tripping your breaker. Disconnect the saw from power source and check your
blade before re-setting the circuit breaker and continuing to saw.

MAINTENANCE
WARNING: To reduce the risk of injury, turn unit off and disconnect machine from
power source before installing and removing accessories, before adjusting or
changing set-ups or when making repairs. An accidental start-up can cause injury.
Cleaning
A WARNING: Blowing dust and chips out of the motor housing using clean, dry compressed
air is a necessary regular maintenance procedure. Dust and chips containing metal particles
often accumulate on interior surfaces and could create an electrical shock or electrocution if
not frequently cleaned out. ALWAYS WEAR SAFETY GLASSES.
jJ, CAUTION: When cleaning, use only a damp cloth on plastic parts. Many household
cleaners contain chemicals which could seriously damage plastic. Also, do not use gasoline,
turpentine, lacquer or paint thinner, dry cleaning fluids or similar products which may seriously
damage plastic parts. Never let any liquid get inside the tool," never immerse any part of the
tool into a liquid.
