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.

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.

!WARNING 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.
