Electric Brake (with interrupters)

Your saw is equipped with an automatic electric brake which is designed to stop the blade from spinning in about two 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.

!WARNING 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 Bosch circular 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 2

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

When the brushes reach a predetermined service length due to normal wear, they will act as current interrupters for electric power to the saw. As the current is interrupted, the motor will “coast” to a stop and will not operate until brushes are replaced. The brushes MUST be replaced as a set. Use only the special “interrupter” brushes designed for this saw, others may fail to function with the braking action.

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.
