SECTION 7: SERVICE

Troubleshooting

Motor & Electrical

Symptom

Possible Cause

Possible Solution

Machine does not

start or a breaker

trips.

1. Emergency stop push-button is engaged/

faulty.

2. Power supply switched OFF or is at fault.

3. Start capacitor is at fault (G0449 only).

4. Motor connection wired incorrectly.

5. Thermal overload relay has tripped.

6. Wall fuse/circuit breaker is blown/tripped.

7. Contactor not getting energized/has burnt

contacts.

8. Wiring is open/has high resistance.

9. Emergency stop push-panel is stuck/switch

is at fault.

10. Motor is at fault.

1. Rotate clockwise slightly until it pops out/replace it.

2. Ensure power supply is switched on; ensure power

supply has the correct voltage.

3. Test/replace if faulty (G0449 only).

4. Correct motor wiring connections.

5. Unplug machine, open magnetic switch cover,

turn amperage dial on Thermal Protection Circuit

Breaker to a higher amperage setting.

6. Ensure circuit size is suitable for this machine;

replace weak breaker.

7. Test for power on all legs and contactor operation.

Replace unit if faulty.

8. Check for broken wires or disconnected/corroded

connections, and repair/replace as necessary.

9. Free push-panel from binding; replace faulty switch.

10. Test/repair/replace.

Machine stalls or is

overloaded.

1. Feed rate too fast for task.

2. Workpiece material is not suitable for this

machine.

3. Run capacitor is at fault (G0449 only).

4. Belt(s) slipping.

5. Motor connection is wired incorrectly.

6. Motor bearings are at fault.

7. Machine is undersized for the task.

8. Contactor not getting energized or has poor

contacts.

9. Motor has overheated.

1. Decrease feed rate.

2. Only cut wood products; make sure moisture

content is below 20% and there are no foreign

materials in the workpiece.

3. Test/repair/replace (G0449 only).

4. Replace bad belt(s) as a matched set, align pulleys,

and re-tension.

5. Correct motor wiring connections.

6. Test by rotating shaft; rotational grinding/loose shaft

requires bearing replacement.

7. Use new sandpaper with appropriate grit; reduce

the feed rate/depth of sanding.

8. Test for power on all legs and contactor operation.

Replace if faulty.

9. Clean off motor, let cool, and reduce workload.
