SECTION 7: SERVICE
Troubleshooting
Symptom Possible Cause Possible Solution
Machine does not
start or a breaker
trips 1. Emergency stop button engaged/at fault.
2. Master power switch off/at fault.
3. Chip guard open/limit switch at fault.
4. Incorrect power supply or incoming
connections.
5. Power supply circuit breaker tripped.
6. Plug/receptacle at fault/wired incorrectly.
7. Motor connection wired incorrectly.
8. Wiring open/has high resistance.
9. Motor or motor components at fault.
1. Rotate button to reset/replace it.
2. Turn master power switch to ON position/replace it.
3. Close guard/replace limit switch.
4. Ensure power supply is correct voltage (
Page 10),
and connected properly (
Page 17).
5. Ensure circuit size is correct/replace weak breaker.
6. Test for good contacts; correct the wiring.
7. Correct motor wiring connections (
Page 46).
8. Check/fix broken, disconnected, or corroded wires.
9. Test/repair/replace.
Machine stalls,
lacks power or is
overloaded. 1. Feed rate/cutting speed too fast.
2. Machine is undersized or tooling is
incorrect for the task.
3. Motor bearings are at fault.
4. Motor overheats.
5. Motor or motor components at fault.
1. Decrease feed rate/cutting speed.
2. Use smaller or sharper tool; reduce feed rate or
spindle speed; use coolant if possible.
3. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
4. Clean off motor, let cool, and reduce workload.
5. Test/repair/replace motor.
Machine has
vibration or noisy
operation. 1. Excessive depth of cut.
2. Tooling is loose or improperly installed.
3. Tooling is dull or chattering.
4. Machine is incorrectly anchored or sits
unevenly.
5. Motor or machine component is loose.
6. Motor fan is rubbing on fan cover.
7. Motor bearings are at fault.
1. Decrease depth of cut.
2. Make sure tooling is properly secured.
3. Replace/resharpen tooling; index bit to workpiece;
use appropriate feed rate and cutting RPM.
4. Tighten/replace anchors; relocate/shim machine.
5. Inspect/replace stripped or damaged bolts/nuts, and
re-tighten with thread locking fluid.
6. Replace dented fan cover or damaged fan.
7. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
Lamp will not light. 1. Master power switch not turned on.
2. Bulb is burned out.
3. Short in wiring or wired incorrectly. 1. Turn master power switch to ON position.
2. Replace bulb.
