Troubleshooting

Possible Solution
1. Turn power switch 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 57).
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.
8. Check for broken wires or corroded/disconnected
connections, and repair/replace as necessary.
9. Test/replace if faulty.
10. Repair/replace.
11. Close wheel covers.
12. Repair/replace limit switch, or stop pressing foot
brake.
1. Replace run capacitor.
2. Use wood with correct moisture content, without
glues, and little pitch/resins.
3. Decrease feed speed. See Basic Cutting Tips on
Page 32.
4. Replace bad V-belt, align pulleys, and re-tension
(Page 48 & 49).
5. Adjust blade tracking and tension to factory
specifications. See Page 19 or 24.
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 57).
9. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
10. Let motor cool, clean it off, and reduce workload.
11. Repair/replace.
