Troubleshooting
Possible Solution
1. Ensure correct power supply voltage and circuit size
(Page 11).
2. Test for good contacts; correct wiring (Page 52).
3. Ensure circuit is free of shorts. Reset circuit breaker or
replace fuse.
4. Correct motor wiring connections (Page 52).
5. Test/replace if at fault.
6. Adjust centrifugal switch/clean contact points. Replace
either if at fault.
7. Fix broken wires or disconnected/corroded
connections (Page 52).
8. Replace switch.
9. Replace motor.
1. Sharpen/replace blade (Page 38). Use correct
blade (Page 32).
2. Decrease feed rate/cutting speed.
3. Use correct type/size of metal.
4. Adjust blade tracking (Page 22) and tension (Page
24).
5. Clean/tension/replace belt (Page 46); ensure
pulleys are aligned.
6. Correct motor wiring connections (Page 52).
7. Test for good contacts/correct wiring (Page 52).
8. Tighten/replace loose pulley/shaft.
9. Use correct, sharp blade; reduce feed rate/depth of
cut; use cutting fluid if possible.
10. Clean motor, let cool, and reduce workload.
11. Test/repair/replace.
12. Move machine closer to power supply; use shorter
extension cord.
13. Adjust centrifugal switch/clean contact points. Replace
either if at fault.
14. Replace gear reducer.
15. Replace motor.
