Brake Operation
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 sys-
tem is your best protection against uninten-
tional contact with a spinning saw blade. NEV-
ER wedge open or defeat the closing action of
the lower guard.
Know the charge state of
your battery. The electric
braking action is initiated ONLY by the release
of the trigger switch and in a tool that has pow-
er available. When electrical power is lost due
to a discharged battery or other causes, the
electric brake will not operate, and the motor
will gradually slow down. Unexpected run-
down time may cause property damage and/or
personal injury.
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 re-
lease the trigger switch. It is useful when mak-
ing certain cuts in wood where a coasting blade
would result in a wide, imprecise cut.
Braking starts once the power is turned off.
The brake requires a charged battery to func-
tion. Stopping time will vary depending on,
among other factors, saw blade used, and num-
ber of actuations. The electric brake of your mi-
ter saw has been designed for a high degree of
reliability, but unexpected circumstances such
as contamination or failure of the motor's com-
ponents can cause the brake to not activate. If
the tool operates but the brake does not con-
sistently stop the blade in about 5 seconds, DO
NOT use the miter saw and have it serviced by
a Bosch Factory Service Center or Bosch autho-
rized service facility.
