Motor Thermal Overload Protector
IMPORTANT: To avoid motor damage, this motor should
be blown out orvacuumed frequently to prevent sawdust
buildup which will interfere with normal motor ventilation.
Your saw is equipped with a manual-reset thermal over-
load protector designed to open the power line circuit
when the motor temperature exceeds a safe level, motor
is overloaded or a low voltage condition exists.
WARNING: Avoid thrown objects or blade con.
tact from unexpected starting, if the protector
stops the saw motor, immediately turn the saw
switch "OFF", remove the key and allow motor
time to cool.
1. After cooling to a safe operating temperature, the
overload protector can be closed manually by push-
ing the red button on the end of the motor. If the red
button will not click into place immediately, the motor
is still too hot and must be allowed to cool for a while
longer.
The time required for the motor to cool may be equal
to the length of time the saw was used before the
thermal overload protector opened, to shut of! elec-
trical flow, An audible click will indicate the protector
is closed.
2_ As soon as the red button will click into running posi-
tion. the saw may be started and operated normally.
3. Frequent "blowing" of fuses or tripping of circuit
breakers may result if:
a. MOTOR IS OVERLOADED - Overloading can
occur if you feed too rapidly or if saw is misaligned
b. MOTOR CIRCUIT IS FUSED DIFFERENTLY
FROM RECOMMENDATIONS - Always follow
instructions for the proper fuse/breaker, Do not
use a fuse/breaker of greater capacity without con.
suiting a qualified electrician
c. LOW VOLTAGE - Although the motor is designed
for operation on the voltage and frequency speci-
fied on motor nameplate, normal loads will be han-
died safety on voltage not more than 10% above
or below the nameplate voltage. Heavy loads.
however, require that voltage at motor terminals
equals the voltage specified on nameplate.
4. Most motor troubles may be traced to loose or incor-
rect connections, overloading, reduced input voltage
(such as small size wire in the supply circuit) or to
overly long supply circuit wire. Always check the con-
nections, the load and the supply circuit whenever
motor fails to perform satisfactorily. Check wire sizes
and length with the Wire Size Chart below.
Wire Sizes
The use of any extension cord will cause some loss of
power. To keep this to a minimum and to prevent over-
heating and motor burn-out, use the table below to
determine the minimum wire size (A.W.G.] extension
cord. Use only 3 wire extension cords which have 3
prong grounding type plugs and 3-pole receptacles
which accept the tools plug.
iMPORTANT: For circuits that are farther away from
electrical service box. the wire size must be increased
proportionately in order to deliver ample voltage to the
saw motor.
