Troubleshooting
Possible Solution
1. Ensure correct power supply voltage and circuit
size.
2. Test for good contacts; correct the wiring.
3. Correct motor wiring connections (Page 43).
4. Test/replace if at fault..
5. Adjust centrifugal switch/clean contact points.
Replace either if at fault.
6. Fix broken wires or disconnected/corroded
connections.
7. Test/replace switch.
8. Replace motor.
1. Decrease feed rate/cutting speed.
2. Use correct type/size of metal.
3. Clean/tension/replace belt(s); ensure pulleys are
aligned.
4. Correct motor wiring connections.
5. Test for good contacts/correct wiring.
6. Use correct cutter/bit; reduce feed rate; reduce
spindle RPM; use cutting fluid if possible.
7. Test/repair/replace.
8. Move machine closer to power supply; use shorter
extension cord.
9. Test/replace switch.
10. Replace motor.
1. Replace damaged or missing bolts/nuts or tighten if
loose.
2. Inspect/replace belts with a new matched set.
Realign pulleys if necessary.
3. Secure pulley on shaft.
4. Fix/replace fan cover; replace loose/damaged fan.
5. Replace unbalanced chuck; replace/resharpen
cutter; use correct feed rate.
6. Adjust/replace if at fault
7. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
