Motor Thermal Overload Protector

CAUTION: To reduce the risk of motor damage,
this motor should be blown out or vacuumed fre-
quently 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, when
motor is overloaded or when a low voltage condition
exists.
WARNING: To reduce the risk of thrown objects or
blade contact from unexpected starting. If the pro-
tector 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 over-
load protector can be reset by pushing 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. NOTE: An audible click will
indicate the protector is reset, push hard to hear the
click.
2. As soon as the red button is reset, the saw may be
started and operated normally.
3. Frequent "blowing" of fuses or tripping of circuit break-
ers 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 recommenda-
tions - Always follow instructions for the proper fuse/
breaker. Do not use a fuse/breaker of greater capac-
ity without consulting a qualified electrician.

Wire Sizes

NOTE: Make sure the proper extension cord is used and
is in good condition.
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 shown 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-prong receptacles which
accept the tool's plug.
c. Low voltage - Although the motor is designed for
operation on the voltage and frequency specified on
motor nameplate, normal loads will be handled
safely 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.
