symptom possible Cause
dust collector 1. dust collection drum is full.
does not 2. Filter is dirty.
adequately 3. restriction in the duct line.
collect dust
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 not flowing
through the dust lines 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.

possible solution
1. empty collection drum.
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 System Design, beginning on Page 26.
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
System Design on Page 26 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. re-install correctly sized ducts and fittings. refer
to System Design on Page 26 for more solutions.
9. use a dust collection nozzle on a stand.
10. install a larger dust collector to power your dust
collection system.
