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 motors 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.
