Bosch Power Tools 4405 Saw User Manual


 
Electrical Requirements
1.
Connect this saw to a 120V, 15-amp branch cir-
cuit with a 15-amp time delay fuse or cir
cuit
breaker. Using the wrong size fuse can damage
the motor.
2.
Fuses may “blow” or circuit breakers may trip
fr
equently if motor is overloaded. Overloading
can occur if you feed the blade into the work-
piece too rapidly, start and stop too often in a
short time, or use the wrong blade for
the application.
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
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 com-
ponents 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 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.
