5. Thermal protection circuit breaker amper
-
age is set too low or motor is at fault.
6. Power supply is at fault/switched OFF.
7. Motor ON/OFF switch is at fault.
8. Wiring is open/has high resistance.
9. Start capacitor is at fault.
10. Motor is at fault.

12. Foot brake limit switch is at fault or is
pressed down (switch is not closed).
1. Turn key to "1".
2. Rotate clockwise until it pops out/replace.
3. Test for good contact or correct the wiring.
4. Correct motor wiring connections (
Page 50).
5. Unplug machine, open magnetic switch cover, turn
amperage dial on Thermal Protection Circuit Breaker
to a higher amperage setting. If switch is maxed out,
replace motor.
6. Ensure hot lines have correct voltage on all legs and
main power supply is switched
ON.
7. Replace faulty ON/OFF switch.

6. Ensure all hot lines have correct voltage on all legs.
7. Test for good contacts and correct wiring.
8. Correct motor wiring connections (
Page 50).
9. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
10. Let motor cool, clean it off, and reduce workload.
