Symptom
Possible Cause
Possible Solution
Dust collector does
not adequately collect
dust or chips; poor
performance.
1. Collection bag full.
2. Canister filter clogged/at fault.
3. Ducting blocked/restricted.
4. Dust collector too far away from point of
suction; duct clamps not properly secured;
too many sharp bends in ducting.
5. Lumber is wet and dust is not flowing
smoothly through ducting.
6. Ducting has one or more leaks, or too
many open ports.
7. Not enough open branch lines at one
time, causing velocity drop in main line.
8. Ducting and ports are incorrectly sized.
9. The machine dust-collection design
inadequate.
10. Dust collector undersized.
1. Empty collection bag.
2. Clean canister filter; replace canister filter.
3. Remove ducting from dust collector inlet and
unblock restriction. A plumbing snake may be
necessary.
4. Relocate dust collector closer to point of suction;
re-secure ducts; remove sharp bends.
5. Only process lumber with less than 20% moisture
content.
6. Seal/eliminate all ducting leaks; close dust ports
for lines not being used. Refer to Designing the
System in manual.
7. Open 1 or 2 more blast gates to different branch
lines to increase main line velocity.
8. Install correctly sized ducts and fittings
9. Use dust-collection hood on stand.
10. Install larger dust collector.
Dust collector blows
sawdust into the air.
1. Duct clamps or filter bag(s) are not
properly clamped and secured; ducting
loose/ damaged.
2. Cylinder or funnel seals are loose or
damaged.
1. Re-secure ducts and filter bag, making sure duct
and bag clamp are tight; tighten/replace ducting.
2. Retighten all mounting and sealing points;
replace damaged seals/gaskets.
