1.
Connect this saw to a 120V, 15-amp branch circuit with
a 15-amp time delay fuse or circuit breaker. Using the wrong
size fuse can damage the motor.
2.
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.
3.
Most motor troubles may be traced to loose or incorrect
connections, overload, low voltage (such as small size wire in
the supply circuit or to 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.
This wiring diagram can be used only with the switch (Part No. 2610910020) supplied with your miter saw.
WARNING
!
Other switches may look the same but internal switch components can be different, thus creating electrical
shock hazard if wired according to this diagram.

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 (5) seconds, DO NOT
use saw and have it serviced immediately.

intended as a safety feature. Remember
to let the saw blade come to a complete stop before
removing 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.
