Troubleshooting
Motor & Electrical
Symptom Possible Cause Possible Solution
Machine does not
start or a breaker
trips.
1. Plug/receptacle is at fault or wired incor-
rectly.
2. Motor connection wired incorrectly.
3. Wall fuse/circuit breaker is blown/tripped.
4. Overload relay has tripped.
5. Power supply switched Off or is at fault.
6. Wiring is open/has high resistance.
7. Main power switch is at fault.
8. Motor is at fault.
1. Test for good contacts; correct the wiring.
2. Correct motor wiring connections.
3. Ensure circuit size is suitable for this machine;
replace weak breaker.
4. Reset overload relay.
5. Ensure power supply is switch on; ensure power
supply has the correct voltage.
6. Check for broken wires or disconnected/corroded
connections, and repair/replace as necessary.
7. Replace faulty ON/OFF switch.

machining.
4. Correct motor wiring connections.
5. Replace bad V-belt(s).
6. Test for good contacts; correct the wiring.
7. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
8. Use smaller sharp cutters/drill bits; reduce the feed
rate; reduce the spindle RPM; use cutting fluid if
possible.
9. Clean off motor, let cool, and reduce workload.
10. Test for power on all legs and contactor operation.
Replace if faulty.
