Troubleshooting
Motor & Electrical
Symptom Possible Cause Possible Solution
Machine does not
start or a breaker
trips. 1. Dust collector not properly connected to
ducting with resistance at the other end.
2. Incorrect power supply voltage/circuit size.
3. Power supply circuit breaker tripped or fuse
blown.
4. Remote control not working.
5. Motor wires connected incorrectly.
6. Wiring open/has high resistance.
7. ON/OFF switch at fault.
8. Start capacitor at fault.
9. Remote receiver at fault.
10. Machine circuit breaker has tripped.
11. Centrifugal switch at fault.
12. Circuit board at fault.
13. Motor at fault.
1. Connect dust collector to ducting with resistance at
the other end (
Page 26).
2. Ensure correct power supply voltage/circuit size.
3. Ensure circuit is sized correctly and free of shorts.
Reset circuit breaker or replace fuse.
4. Replace battery; stay in signal range (
Page 36).
5. Correct motor wiring connections.
6. Check/fix broken, disconnected, or corroded wires.
7. Inspect/replace remote control/control panel.
8. Test/replace.
9. Inspect/replace.
10. Let motor cool, improve ventilation, and reset;
contact tech support if relay frequently trips.
11. Adjust/replace centrifugal switch if available.
12. Ensure circuit board voltage matches power supply;
Inspect/replace.
13. Test/repair/replace.
Machine stalls or is
underpowered. 1. Motor overheated.
2. Dust-collection ducting problem.
3. Canister filter clogged/at fault.
4. Dust collector undersized.
5. Motor wired incorrectly.
6. Run capacitor at fault.
7. Centrifugal switch at fault.
8. Motor bearings at fault.
1. Allow motor to cool, reset overload if necessary.
2. Clear blockages, seal leaks, use smooth wall duct,
eliminate bends, close other branches ( Page 26).
3. Clean/replace canister filter (
Page 44); wash
canister filter ( Page 44).
4. Move closer to machine/redesign ducting layout/
upgrade dust collector.
5. Wire motor correctly (
Page 46).
6. Test/repair/replace.
7. Adjust/replace centrifugal switch if available.
8. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
Machine has
vibration or noisy
operation. 1. Motor or component loose.
2. Motor fan rubbing on fan cover.
3. Impeller is damaged or unbalanced.
4. Impeller is loose on the motor shaft.
5. Motor bearings at fault.
6. Motor shaft bent.
1. Inspect/replace damaged bolts/nuts, and retighten
with thread-locking fluid.
2. Fix/replace fan cover; replace loose/damaged fan.
3. Inspect impeller for damage/replace.
4. Secure impeller; replace motor and impeller as a set
if motor shaft and impeller hub are damaged.
5. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
6. Test with dial indicator. Replace motor if damaged.
