• Connect this saw to a 120V, 15-amp branch circuit
with a 15-amp fuse or circuit breaker. Using the
wrong size fuse can damage the motor.
• Fuses may "blow" or circuit breakers may trip fre-
quently if motor is overloaded. Overloading can
occur if you feed the blade into the workpiece too
rapidly or start and stop too often in a short time.
• Most motor troubles may be traced to loose or in-
correct connections, overload, low voltage (such
as small size wire in the supply circuit or too overly
long supply circuit wire). Always check the con-
nections, 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.

the motor will gradually slow down. 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.
Remember to let the saw blade come to a com-
plete 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.
when guard becomes jammed on a workpiece.
7. Blade – Use only 12" (305 mm) blades with 1"
(25.4 mm) arbor hole.
8. Blade Wrench/Storage – Used in blade change
process; tightening and loosening blade and blade
guard.
9. Chip Deflector – This protects against large chips
from entering the upper guard.
10. Upper Blade Guard – Covers upper portion of
the blade.
11. Sliding fence – Supports the workpiece and
features cast-in scales for repetitive cuts and holes
to secure an auxiliary fence. Slide left side out prior
to beveling head left. Right side is stationary.
12. Stationary fence – Stationary fence is bolted
to the base and will support the workpiece when the
sliding fence is removed. (Note the right side does
not slide or remove.)
