Electrical
Requirements
1.
Connect this saw to a 120V, 15-amp branch circuit with
a 15-amp time delay fuse or circuit breaker. Using the wrong
size fuse can damage the motor.
2.
Fuses may "blow" or circuit breakers may trip frequently
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.
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 to 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 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.
r!'vAV'-_i_ll_[el
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
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.
r!'vAV'-_i_ll_[el
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.
Wiring Diagram
r !_v*V'-_r`_ll_[e]l
This wiring diagram can be used only with the switch (Part No. 2610910020) supplied with your miter
saw. Other switches may look the same but internal switch components
can be different, thus creating electrical shock hazard if
wired according to this diagram.
