Motor

NOTE: Motors used on wood - working tools are particularly susceptible to the accumulation of sawdust and wood chips

and should be blown out or “vacuumed” frequently to prevent interference with normal motor ventilation and proper op-

eration of the centrifugally-operated starting switch.

Trouble Probable Cause Remedy

Excessive noise 1. Motor 1. Have motor checked by qualified service technician.

Repair service is available at an Authorized Service Cen-

ter.

Motor fails to develop

full power. NOTE:

LOW VOLTAGE:

(Power output of motor

decreases rapidly with

decrease in voltage at

motor terminals. For

example, a reduction of

10% in voltage causes

a reduction of 19% in

maximum power output

of which the motor is

capable and a reduction

of 20% in voltage

causes a reduction of

36% in maximum power

output.)

1. Circuit overloaded with light,

appliances and other motors.

2. Undersize wires or circuit too

long.

3. General overloading of power

company facilities.

1. Do not use other appliances or motors on same circuit

when using the lathe.

2. Increase wire sizes, or reduce length of wiring. See

“motor Specifications and Electrical Requirements”

section.

3. Request a voltage check from the power company.

Motor starts slowly or

failstocomeuptofull

speed.

1. Low voltage will not trip relay.

2. Windings burned out or open.

1. Request voltage check from the power company.

2. Have motor repaired or replaced.

Motor overheats 1. Motor overloaded.

2. Improper cooling. (Air circulation

restricted through motor due to

sawdust accumulating inside of

motor).

1. Take shallower cuts.

2. Clean out sawdust to provide normal air circulation

through motor.

See “Maintenance and Lubrication” section.

Starting switch in

motor will not oper-

ate.

1. Burned switch contacts (due to

extended hold-in periods caused

by low line voltage, etc.)

2. Shorted capacitor

3. Loose or broken connections.

1. Have switch replaced and request a voltage check

from the power company.

2. Have capacitor tested and replace if defective.

3. Have wiring checked and repaired.

Motor stalls

(resulting in blown

fuses or tripped circuit

breakers).

1. Starting switch not operating.

2. Voltage too low to permit motor

to reach operating speed.

3. Fuses or circuit breakers do not

have sufficient capacity.

1. Have switch replaced.

2. Request voltage check from the power company.

3. Install proper size fuses or circuit breakers.

Frequent opening of

fuses or circuit break-

ers.

1. Motor overloaded.

2. Fuses or circuit breakers do not

have sufficient capacity.

3. Starting switch not operating

(motor does not reach speed).

1. Take shallower cuts.

2. Install proper size fuses or circuit breakers.

3. Have switch replaced.
