PROBLEM
POSSIBLE.CAUSE
CORRECTIVE.ACTION
Machine does not
start or a breaker
trips immediately
after startup.
1. Dust collector not properly connected to
ducting.
2. E-Stop Button depressed/at fault.
3. Incorrect power supply voltage or circuit
size.
4. Power supply circuit breaker tripped or
fuse blown.
5. Motor overheated.
6. Machine circuit breaker has tripped.
7. Remote control not working.
8. Wiring open/has high resistance.
9. Centrifugal switch/contact points at fault.
10. Power switch/circuit breaker at fault.
11. Start capacitor at fault.
12. Remote receiver at fault.
13. Motor at fault.
1. Connect dust collector properly (
Page.27
).
2. Rotate E-Stop Button to reset. Replace if at fault.
3. Ensure correct power supply voltage and circuit
size.
4. Ensure circuit is sized correctly and free of shorts.
Reset circuit breaker or replace fuse.
5. Allow motor to cool, reset overload if necessary.
6. Reset circuit breaker on switch.
7. Replace battery; stay in signal range (
Page.6
).
8. Check/fix broken, disconnected, or corroded wires.
9. Adjust/replace centrifugal switch/contact points.
10. Test/replace.
11. Test/replace.
12. Replace.
13. Test/repair/replace.
Machine seems
underpowered.
1. Motor overheated.
2. Dust-collection ducting problem.
3. Canister filter clogged/at fault.
4. Dust collector to far from machine or
undersized for dust-collection system.
5. Run capacitor at fault.
6. Centrifugal switch/contact points at fault.
7. 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.27
).
3. Clean canister filter (
Page. 40
); replace canister
filter (
Page.41
).
4. Move closer to machine/redesign ducting layout/
upgrade dust collector.
5. Test/repair/replace.
6. Adjust/replace centrifugal switch/contact points if
available.
7. Test by rotating shaft; rotational grinding/loose
shaft requires bearing replacement.
Machine has vibra-
tion or noisy
operation.
1. Motor or component loose.
2. Motor fan rubbing on fan cover.
3. Motor mount loose/broken.
4. Centrifugal switch is at fault.
5. Impeller damaged or unbalanced.
6. Motor bearings at fault.
7. 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. Adjust/replace centrifugal switch if available.
5. Replace.
6. Test by rotating shaft; rotational grinding/loose
shaft requires bearing replacement.
7. Test with dial indicator. Replace motor if damaged.
Loud, repetitious
noise, or excessive
vibration coming
from dust collec-
tor (non-motor
related).
1. Dust collector not on a flat surface and
wobbles.
2. Impeller damaged, unbalanced, or loose.
3. Impeller loose on the motor shaft.
1. Stabilize dust collector; lock casters.
2. Disconnect dust collector from power. Inspect
impeller for dents, bends, or loose fins. Replace
impeller if damaged.
3. Secure impeller; replace motor and impeller as a
set if motor shaft and impeller hub are damaged.
