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

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 bag.
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.
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.
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.
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 clamp are tight.
2. retighten all mounting and sealing points, replace
damaged gaskets.
