SECTION 7: SERVICE
Troubleshooting
Symptom Possible Cause Possible Solution
Machine does not
start.
1. Emergency stop button depressed.
2. Plug at fault or wired incorrectly.
3. Incorrect power supply voltage.
4. Wall fuse/circuit breaker is blown/tripped.
5. Wiring is open/has high resistance.
6. Motor wired incorrectly.
7. Control panel buttons at fault.
8. Motor or motor components are at fault.
1. Twist emergency stop button clockwise until it pops
out to reset it.
2. Ensure plug is not damaged and is wired correctly.
3. Ensure power supply voltage matches circuit
requirements (Page 11).
4. Ensure circuit size is correct and a short does not
exist. Reset breaker or replace fuse.
5. Check for broken wires or disconnected/corroded
connections; repair/replace as necessary.
6. Ensure motor wiring is correct (Page 43).
7. Ensure each button is wired correctly; replace if at
fault (Page 42).
8. Test/repair/replace.
Machine stalls or is
overloaded.
1. Feed rate/cutting speed too fast.
2. Wrong cutter type.
3. Machine is undersized for the task or
tooling is incorrect for the task.
4. Motor has overheated.
5. Motor wired incorrectly.
6. Motor bearings are at fault.
7. Motor or motor components are at fault.
1. Decrease feed rate/cutting speed.
2. Use the correct cutter for the task.
3. Use smaller or sharper tooling; reduce feed rate or
spindle speed; use cutting fluid if possible.
4. Clean off motor, let cool, and reduce workload.
5. Ensure motor wiring is correct (Page 43).
6. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
7. Test/repair/replace motor.
Machine has
vibration or noisy
operation.
1. Motor or machine component is loose.
2. Workpiece not secure.
3. Excessive depth of cut.
4. Cutter/tooling is loose.
5. Cutter is dull or at fault.
6. Bit is chattering.
7. Machine is incorrectly anchored to floor or
sits unevenly.
8. Motor fan is rubbing on fan cover.
9. Motor bearings are at fault.
1. Inspect/replace stripped or damaged bolts/nuts, and
re-tighten with thread locking fluid.
2. Properly clamp workpiece on table or in vise.
3. Decrease depth of cut.
4. Make sure tooling is properly secured.
5. Replace/resharpen cutter.
6. Replace/sharpen bit; index bit to workpiece; use
appropriate feed rate and cutting RPM.
7. Tighten/replace anchor bolts; relocate/shim
machine.
8. Replace dented fan cover or damaged fan.
9. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
