Troubleshooting
Possible Solution
1. Close door.
2. Ensure correct power supply voltage and circuit
size.
3. Ensure circuit is sized correctly and free of shorts;
reset circuit breaker or replace fuse.
4. Correct motor wiring connections.
5. Check/fix broken, disconnected, or corroded wires.
6. Replace switch.
7. Test/replace.
8. Test/replace.
9. Replace door safety/limit switch.
10. Allow to cool and reset; replace if at fault.
11. Test all legs and ensure good contacts; replace if at
fault.
12. Test/repair/replace.
1. Decrease feed rate/cutting speed.
2. Use correct, sharp blade; reduce feed rate/depth of
cut; use lubricant if necessary.
3. Only cut correct material for saw blade/type.
4. Use the correct blade for the operation. Refer to
Blade Selection section beginning on Page 31.
5. Maintain better workpiece control, or cut workpiece
with different technique or machine.
6. Adjust blade tracking and tension (Page 23).
7. Tension/replace belt(s) (Page 45). Clean belt(s).
8. Clean motor, let cool, and reduce workload.
9. Wire motor correctly (Page 55).
10. Replace blades (Page 34).
11. Replace loose pulley/shaft.
12. Test all legs and ensure good contacts; replace if at
fault.
1. Retighten/replace damaged bolts/nuts.
2. Replace warped/bent blade.
3. Inspect/replace belts with a new matched set.
4. Fix/replace fan cover; replace loose/damaged fan.
5. Re-align pulley/replace pulley set screw and key.
6. Tighten mounting bolts; relocate/shim machine.
7. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
