TROUBLESHOOTING
SYMPTOM
Motor will not start,
Motor will not start;
fuses or circuit
breakers blow.
Motor fails to develop
full power (power out-
put of motor decreases
rapidly with decrease
in voltage at motor
terminals).
Motor overheats.
Motor stalls (resulting
in blown fuses or
tripped circuit).
Machine slows down
while operating.
Abrasive belt runs off
top wheel.
POSSIBLE CAUSE(S)
1,, Low voltage. '
2, Open circuit in motbror
loose cohnections, i
1,, Short circfL_itin line cord or
plug.
2. Short circuit in motor or
1oose connections.
3o Incorrect fuses or circuit
,breakers in powerline,
t, Power line overloaded with
lights, appliances and other
motors.
2, Undersize wires or circuits
too long,,
& General overloading of
power company's facilities,
1_ Motor overloaded.
2_ Air circulation through the
motor restricted.
1, Short circuit in motor or
loose connections.
2. Low voltage,
3. incorrect fuses or circuit
breakers in power line.
4, Motor overloaded.
Applying too much pressure
to workpieceo
Not tracking properly,
CORRECTIVE ACTION
1. Check power line for proper voltage_
2o Inspect all lead connecti.ons on motor for
loose or open connection°
1. Inspect tine cord or plug for damaged
Insulation and shorted wires
2_ Inspect all lead connections on motor for
loose or shorted terminals or worn insulation
on wires.
:3_ Insta!l correct fuses or circuit breakers°
1. Reduce the load on the power line_
2, Increase wire sizes, or reduce length of
wiring.
3, Request a voltage check from the power
companyo
1. Reduceload on motor.
2. Clean out motor to provide normal air
circulation through motor,
2.
4_
Inspect connections in motor for loose or
shorted terminals or worn insulation on wires,
Correct the low line voltage conditions.
Install correct fuses or circuit breakers•
Reduce load on motor_
Ease up on pressure.
