Motor Specifications and Electrical Requirements (continued)

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-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.

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.

1. After cooling to a safe operating tem-

perature, the overload 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 over-

load protector opened. NOTE: An audi-

ble 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 han-

dled 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, over-

loading, 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 min-

imum 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.
