TROUBLESHOOTING GUIDE
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. Blown line fuse or tripped circuit
breaker
2. Low line voltage
3. Defective switch
4. Defective, blown capacitor
1. Overloading due to binding
2. Defective plug
3. Defective cord
4. Defective switch
5. Motor wired for different
line voltage
6. Faulty internal wiring
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. Motor wired for different line voltage
4. Incorrect fuses or circuit breakers in
power line
5. Motor overloaded
Applying too much pressure to
workpiece
Not tracking properly
1. If fuse is blown, replace with fuse of proper size.
If breaker tripped, reset it
2. Check power supply for voltage and correct as
needed
3. Replace switch
4. Replace capacitor
1. Clean around wheels and shaft and/or replace
bearings
2. Replace plug
3. Replace cord
4. Replace switch
5. Rewire motors as per line voltage
(See “Electrical Connections”, pages 5 and 6)
6. Contact authorized service center
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. Rewire motor as per line voltage
4. Install correct fuses or circuit breakers
(See “Electrical Connections”, pages 5 and 6)
5. Reduce load on motor
Ease up on pressure
See “Belt Installation”, page 7
