SYMPTOM
Motor will not start, or it
growls on start up.
Motor runs slower than
normal.
Loud, repetitious noise, or
excessive vibration coming
from dust collector.
Dust collector does not
adequately collect dust or
chips; poor performance.

Troubleshooting
POSSIBLE CAUSE
1. Power supply fuse or circuit breaker
has tripped.
2. Toggle switch is broken inside.
3. Start capacitor is at fault.
4. Motor fan cover is dented, stopping
the fan from being able to spin.
5. Motor is at fault.
1. Poor electrical connection.
2. Low power source voltage.
3. Motor is at fault.
1. Dust collector is not on a flat
surface and wobbles.
2. Impeller fan is damaged and
unbalanced.
3. The motor mounting is loose.
4. Impeller is loose on the motor
shaft.
5. Motor fan cover is dented, causing
the motor fan to hit the cover while
spinning.
1. Dust collection bag is full.
2. There is a restriction at the inlet
grate.
3. The dust collector is too far away
from the point of suction, or there
are too many sharp bends in the
ducting.
4. The lumber is wet and not flowing
through the dust lines smoothly.
5. There is a leak in the ducting, or a
series of small leaks, or too many
open ports.
6. There is a restriction in the ducting,
or the ducting and ports are
incorrectly sized.
7. The machine dust collection design
is inadequate.
8. The dust collector is too small for
the dust collection system.
CORRECTIVE ACTION
1. Disconnect power, and inspect circuit for electrical
shorts and repair. Replace circuit breaker if it is old
or has tripped many times.
2. Disconnect power, and use an ohmmeter to check
switch terminals for continuity, and replace switch if
required.
3. Replace start capacitor.
4. Replace motor fan cover (and fan, if damaged).
5. Replace motor.
1. Inspect the power supply for loose, corroded, or
overheated electrical connections and repair.
2. Have the power source voltage checked; reduce
the length of extension cord.
3. Replace the motor.
1. Stabilize the dust collector.
2. Unplug dust collector, and inspect the impeller for
dents, bends, loose fins. Replace impeller if any
damage is found.
3. Make sure all fasteners on the dust collector are
tight.
4. Replace the motor and impeller as a set if the
motor shaft and the impeller hub are damaged.
5. Replace motor fan cover.
1. Empty bags.
2. Remove dust line from dust collector inlet and
clean debris from the inlet grate (and wire-
connector, if installed).
3. Relocate the dust collector closer to the point of
suction, and rework ducting without sharp bends.
Refer to the Dust Collection Basics handbook
(ISBN 0-9635821-2-7) to help configure your dust
system.
4. Process lumber with less than 20% moisture
content.
5. Rework the ducting as to eliminate all leaks, and
refer to the Dust Collection Basics handbook (ISBN
0-9635821-2-7) for more solutions.
6. Rework the ducting as to eliminate all restrictions,
and refer to the Dust Collection Basics handbook
(ISBN 0-9635821-2-7) for more solutions.
7. Use proper dust collection accessories.
8. Install a larger dust collector to power your dust
collection system.
