3. The motor mounting or housing
connections are loose.
4. Impeller is loose on the motor shaft.

motor fan to hit the cover while spinning.

or chips; poor
performance.
4. The dust collector is too far away from
the point of suction, or there are too many
sharp bends in the ducting.
5. The lumber is wet and dust is not flowing
through the ducting smoothly.
6. There is a leak in the ducting, or a series
of small leaks, or too many open ports.
7. There are not enough open branch lines at
one time, thereby causing a velocity drop
in the main line.
8. The ducting and ports are incorrectly
sized.
9. The machine dust collection design is
inadequate.
10. The dust collector is too small for the dust
collection system.

damaged.

Possible Solution
1. Stabilize the dust collector.
2. Disconnect dust collector from power, 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 collection bags.
2. Clean filter.
3. Remove dust line from dust collector inlet and
unblock the restriction in the duct line. A plumbing
snake may be necessary.
4. Relocate the dust collector closer to the point of
suction, and rework ducting without sharp bends.
Refer to Designing the System, beginning on
Page 35.
5. Process lumber with less than 20% moisture
content.
6. Rework the ducting to eliminate all leaks. Close
dust ports for lines not being used. Refer to
Designing the System beginning on Page 35 for
more solutions.
7. Open 1 or 2 more blast gates to different branch
lines to allow the velocity in the main line to
increase.
8. Reinstall correctly sized ducts and fittings. Refer to
Designing the System beginning on Page 35 for
more solutions.
9. Use a dust collection nozzle on a stand.
10. Install a larger dust collector to power your dust
collection system.
1. Re-secure ducts and dust collection bag, making
sure duct and bag clamps are tight and completely
over the ducts and bags.
2. Retighten all mounting and sealing points, replace
damaged gaskets.
