SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Motor will not start
Motor will not start; fuses blown or
circuit breakers tripped
Motor fails to develop full power
(power output of motor decreases
rapidly with decrease in voltage at
motor terminals)
Motor overheats
Motor stalls (resulting in blown fuses
or tripped circuit breakers)
Machine slows down while operating
Abrasive belt runs off top wheel
1. Low voltage
2. Open circuit in motor or loose connections
1. Short circuit in line cord or plug
2. Short circuit in motor or loose connections
3. Incorrect fuses or circuit breakers in power
line
1. Power line overloaded with lights, appli-
ances and other motors
2. Undersized wires or circuits too long
3. General overloading of power company’s
facilities
Motor overloaded
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 workpiece
Not tracking properly
1. Check power line for proper voltage
2. Inspect all lead connections on motor for loose or
open connection
1. Insect line 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. Install correct fuses or circuit breakers
1. Reduce load on power line
2. Increase wire sizes, or reduce length of wiring
3. Request a voltage check from power company
Reduce load on motor.
1. Inspect connections in motor for loose or shorted
terminals or worn insulation on lead wires
2. Correct the low line voltage conditions
3. Install correct fuses or circuit breakers
4. Reduce load on motor
Ease up on pressure
