3. Motor wires connected incorrectly.
4. Start capacitor at fault.
5. Centrifugal switch adjustment/contact
points at fault.
6. Wiring broken, disconnected, or corroded.
7. Spindle rotation switch at fault.
8. Motor or motor bearings at fault.
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..

Replace either if at fault.
6. Fix broken wires or disconnected/corroded
connections.
7. Test/replace switch.
8. Replace motor.
Machine stalls or is
overloaded. 1. Feed rate/cutting speed too fast.
2. Wrong workpiece material.
3. Belt(s) slipping/pulleys misaligned.
4. Motor wires connected incorrectly.
5. Plug/receptacle at fault/wired incorrectly.
6. Machine undersized for task.
7. Run capacitor at fault.
8. Extension cord too long.
9. Spindle rotation switch at fault.
10. Motor or motor bearings at fault
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.
Machine has
vibration or noisy
operation. 1. Motor or component is loose.
2. V-belt(s) worn, loose, pulleys misaligned or
belt slapping cover.
3. Pulley is loose.
4. Motor fan rubbing on fan cover.
5. Chuck or cutter at fault.
6. Centrifugal switch needs adjustment/at
fault.
7. Motor bearings at fault.
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.
