Troubleshooting
Motor & Electrical
Symptom possible Cause possible Solution
machine does
not start or a
breaker trips. 1. power supply is at fault/switched oFF.
2. plug/receptacle is at fault or wired incorrectly.
3. Wiring is open/has high resistance.
4. motor connection wired incorrectly.
5. Start capacitor is at fault (110v only).
6. motor on/oFF switch is at fault.
7. Centrifugal switch is at fault.
1. ensure hot lines have correct voltage on all legs and
main power supply is switched ON.
2. test for good contacts; correct the wiring.
3. Check for broken wires or disconnected/corroded
connections, and repair/replace as necessary.
4. Correct motor wiring connections ( Page 56).
5. test/replace.
6. replace faulty on/oFF switch.
7. Adjust/replace centrifugal switch.
machine stalls or
is underpowered. 1. incorrect workpiece material.
2. Feed rate too fast for task.
3. v-belt slipping.
4. motor connection is wired incorrectly.
5. plug/receptacle is at fault.
6. motor bearings are at fault.
7. motor has overheated.
8. motor is at fault.
9. Centrifugal switch is at fault.
1. Use wood with correct moisture content (20% or
less), without glues, and little pitch/resin.
2. decrease feed rate.
3. tighten/repair/replace (
Pages 47 and 48).
4. Correct motor wiring connections ( Page 56).
5. test for good contacts; correct the wiring.
6. test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
7. Clean off motor, let cool, and reduce workload.
8. test/repair/replace.
9. Adjust/replace centrifugal switch.
machine has
vibration or noisy
operation. 1. motor or component is loose.
2. v-belt worn or loose.
3. motor fan is rubbing on fan cover.
4. pulley is loose.
5. machine is incorrectly mounted or sits unevenly
on floor.
6. Blade is at fault.
7. Cast iron motor mount loose/broken.
8. Centrifugal switch is at fault.
9. motor or spindle bearings are at fault.
1. inspect/replace stripped or damaged bolts/nuts, use
thread locking fluid, and retighten.
2. tension v-belt ( Page 47) or replace v-belt (Page
48).
3. replace dented fan cover; replace damaged fan.
4. tighten pulley set screw.
5. Adjust stand feet.
6. replace blade.
7. tighten/replace.
8. Adjust/replace centrifugal switch..
9. test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
