Connect this saw to a 120V, 15-amp branch cir-
cuit with a 15-amp fuse or circuit breaker. Using
the wrong size fuse can damage the motor.
Fuses may "blow" or circuit breakers may trip
frequently if motor is overloaded. Overloading
can occur if you feed the blade into the
workpiece too rapidly or start and stop too often
in a short time.
Most motor troubles may be traced to loose or
incorrect connections, overload or low voltage
(such as small size wire in the supply circuit or
overly long supply circuit wire). Always check
the connections, the load and the supply circuit
whenever motor does not work well.
Electric Brake
Your saw is equipped with an automatic electric
brake which is designed to stop the blade from
spinning in about five (5) seconds after you release
the trigger switch. It is useful when making certain
cuts in wood where a coasting blade would result in
a wide, imprecise cut.

When electrical power is lost due
WARNING
to blown fuse or other causes,
the motor will gradually slow down and the
braking action is initiated ONlY by the release of
the trigger switch.
The electric blade brake of your miter saw has been
designed for highest degree of reliability, but
unexpected circumstances such as contamination on
the commutator and brushes or failure of motor's
components can cause the brake not to activate. If
this condition occurs, turn the saw "ON" and "OFF"
four to five times without contacting the workpiece. If
the tool operates but the brake does not consistently
stop the blade in about five seconds, DO NOT use
saw and have it serviced immediately.
The brake action of this saw is
WARNING
not intended as a safety feature.
Remember to let the saw blade come to a
complete stop before raising the blade from the
workpiece. As always, the guard system is your
best protection against unintentional contact
with a spinning saw blade. NEVER wedge open
or defeat the closing action of the lower guard.
