CORRECTIVE ACTION
1. Correct short; replace fuse in electrical box.
2. Rotate emergency stop button until it pops out;
replace it if faulty.
3. Correct motor wiring connections; refer to diagram
inside motor junction wiring box cover.
4. Turn amperage dial to increase working amps and
push the reset pin; replace if tripped multiple
times.
5. Test for power on all legs and contactor operation;
replace unit if faulty.
6. Ensure circuit is correct size for machine load
(refer to Page 10); replace weak breaker.
7. Ensure hot lines have correct voltage on all legs
and main power supply is switched on.
8. Replace faulty forward/reverse switch.
9. Check for broken wires or disconnect/corroded
connections, and repair/replace as necessary.
10. Test/repair/replace motor.
1. Use wood with correct moisture content (less than
20%), without glues, and has little pitch/resins.
2. Decrease feed rate.
3. Seal all leaks, size ducts correctly, eliminate bends,
and refer to Dust Collection Basics Handbook (ISBN
0-9635821-2-7) for further recommendations.
4. Re-tention/replace V-belt (refer to Page 41).
5. Correct motor wiring connections.
6. Replace loose pulley/shaft.
7. Test by rotating motor shaft; rotational grinding/
loose shaft requires bearing replacement.
8. Use sharp cutters; reduce the feed rate/depth of
cut.
9. Clean off motor, let cool, and reduce workload.
10. Test for power on all legs and contactor operation;
replace if faulty.
11. Test/repair/replace motor.
1. Inspect/replace stripped or damaged fasteners, and
retighten with thread locking fluid.
2. Inspect/replace V-belt (refer to Page 41).
3. Replace dented fan cover/fan.
4. Replace cutter; tighten/replace loose spindle (Page
44).
5. Secure machine to floor; reposition; re-shim.
6. Replace cracked elevation housing.
7. Realign/replace pulley shaft, pulley, set screw, and
key as required.
