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.
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.
