shooting.
Probable
Cause
What
to Do
Motor will not run.
Protector open, circuit broken.
Model 113.197150
only
Low voltage.
Push red button located on top of
motor.
Listen for audible click
that indicates
motor is reset.
Model 113.197150
only.
Check power
line for proper
voltage.
Motor will not run and
fuses blow.
Short circuit in line, cord, or
plug.
Inspect line, cord, and plug for
damaged insulation and shorted
wires.
Short circuit in motor
or loose
connections.
Inspect
all terminals
in motor
for loose or shorted
terminals
or worn insulation
wires.
Incorrect fuses in power line.
Install correct fuses.
Motor fails to develop full
power.
(Power output of motor
decreases rapidly with
decrease in voltage at
motor terminals. For ex-
ample: a reduction of
10% in voltage causes a
reduction of 19% in maxi-
mum power output of
which the motor is
capable, while a reduction
of 20% in voltage causes a
reduction of 36% in maxi-
mum power output.)
Power line overloaded
with
lights, appliances,
and other
motors.
Reduce
the line load.
Undersize
wires or circuit too
long.
Increase wire sizes, or
reduce
length of wiring.
General
overloading
of power
company's
facilities.
(In many sections
of the
country,
demand
for electrical
power exceeds
the capacity
of
existing generating
and distribu-
tion systems).
Request a voltage check from
power company.
