TROUBLE SHOOTING -- 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 operation of the centrifugally-operated
starting switch.

VOLTAGE: (Power out-
put of motor decreases
rapidly with decrease in
voltage at motor termi-
nals. For example, a re-
duction of 10% in volt-
age causes a reduc-
tion of 19% in maximum
poweroutputof which
the motor is capable
and a reduction of 20%
in voltage causes a re-
duction of 36% in max-
imum power output,)
Motor starts slowly
or fails to come up
to full speed.
Motor overheats.
Motor stalls

3, Starting motorwhile head-
stock is not in normal
operating position.
4. Starting relay not
operating,
1. Motor overloaded.
2. Impropercooling. (Air
circulation restricted
through motor due to
sawdust, accumulating
inside of motor.)
1. Voltage too low to permit
motor to reach operating
speed.

1, Bed sections are not
straight and level
with each other.
REMEDY
1. Have motor checked by qualified service
technician. Repair service is available at
your nearest Sears store.
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.
1, Request voltage check from the power company.
2. Have motor repaired or replaced.
