Motor Thermal Overload Protector
CAUTION: To reduce the risk of
motor damage, this motor should be
blown out or vacuumed frequently
to prevent sawdust buildup which
will interfere with normal motor
ventilation.
WARNING: To reduce the risk of
thrown objects or blade contact
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.
Your saw is equipped with a manual-reset
thermal-overload 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.
1. After cooling to a safe operating
temperature, the overload protector can
be reset by pushing the red button on the
junction box 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 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 consulting a qualified
electrician.
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 incorrect connections,
overloading, reduced input 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 fails to
perform satisfactorily. Check wire sizes
and length with the Wire Size Chart
below.
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 overheating 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.
