Wiring Diagram

This wiring diagram can be used only with the switch (Part No. 2610910020) 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.

Electrical Requirements

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.

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 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.

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

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.
