Symptom
Possible Cause
Possible Solution
Machine does not
start, or powersupply
fuse/breaker trips
immediately after
startup.
1. Dust collector not properly connected to
ducting.
2. Incorrect power supply voltage or circuit
size.
3. Power supply circuit breaker tripped or
fuse blown.
4. Motor overheated.
5. Machine circuit breaker has tripped.
6. Wiring open/has high resistance.
7. Power switch/circuit breaker at fault.
8. Start capacitor at fault.
9. Motor at fault.
1. Connect dust collector to ducting.
2. Ensure correct power supply voltage and circuit
size.
3. Ensure circuit is sized correctly and free of shorts.
Reset circuit breaker or replace fuse.
4. Allow motor to cool, reset overload if necessary.
5. Reset circuit breaker on switch.
6. Check/fix broken, disconnected, or corroded
wires.
7. Test/replace.
8. Replace.
9. Test/repair/replace.
Machine seems
underpowered.
1. Motor overheated.
2. Dust-collection ducting problem.
3. Canister filter clogged/at fault.
4. Dust collector too far from machine or
undersized for dust-collection system.
5. Run capacitor at fault.
6. 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.
3. Clean canister filter; replace canister filter.
4. Move closer to machine/redesign ducting layout/
upgrade dust collector.
5. Test/repair/replace.
6. 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. Motor mount loose/broken.
4. Impeller damaged, unbalanced, or loose.
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. Tighten/replace.
4. Inspect/tighten/replace.
5. Test by rotating shaft; rotational grinding/loose
shaft requires bearing replacement.
6. Test with dial indicator. Replace motor if
damaged.
Loud, repetitious
noise, or excessive
vibration coming from
dust collector (non-
motor related).
1. Dust collector not on a flat surface and
wobbles.
2. Impeller damaged and unbalanced.
3. Impeller loose on the motor shaft.
1. Stabilize dust collector; lock casters.
2. Inspect/replace.
3. Secure impeller; replace motor and impeller as a
set if motor shaft and impeller hub are damaged.
