Electrical Requirements

1. Connect this saw to a 120V, 15-amp branch cir-

cuit 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 work-

piece 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

too 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 spin-

ning 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 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 unex-

pected circumstances such as contamination on the

commutator and brushes or failure of motor’s compo-

nents can cause the brake not to activate. If this con-

dition 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.

The brake action of this saw is 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.

Wiring Diagram

This wiring diagram can be used only with switch (Part No. 2610911881) supplied with your

miter saw. Other switches may look the same, but internal switch components can be different,

thus creating electrical shock hazard if wired according to this diagram.
