Model G0777/G0777HEP (Mfd. Since 04/19)
-45-
Symptom
Possible Cause
Possible Solution
Loud, repetitious
noise, or excessive
vibration coming
from dust collector
(non-motor related).
1. Dust collector not on a flat surface and
wobbles.
2. Impeller is damaged and unbalanced.
3. Impeller is loose on the motor shaft.
1. Stabilize dust collector; lock casters.
2. Disconnect dust collector from power. Inspect
impeller for dents, bends, or loose fins. Replace
impeller if damaged.
3. Secure impeller; replace motor and impeller as a set
if motor shaft and impeller hub are damaged.
Dust collector does
not adequately
collect dust or chips;
poor performance.
1. Dust collection bag is full.
2. Filter is clogged/at fault.
3. Ducting blocked/restricted.
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
smoothly through ducting.
6. Ducting has one or more leaks, or too
many open ports.
7. Not enough open branch lines at one time,
thereby causing a velocity drop in the main
line.
8. Ducting and ports are incorrectly sized.
9. The machine dust collection design is
inadequate.
10. Dust collector is undersized.
1. Empty collection bag.
2. Rotate filter brush handle to clean filter; replace
(
Pages 4 & 46).
3. Remove ducting from dust collector inlet and
unblock the restriction. A plumbing snake may be
necessary.
4. Relocate the dust collector closer to the point of
suction; remove sharp bends in ducting.
5. Process lumber with less than 20% moisture
content.
6. Seal/eliminate all ducting leaks; close dust ports for
lines not being used.
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 a dust collection hood on a stand (
Page 42).
10. Install a larger dust collector.
Dust collector blows
sawdust into the air.
1. Duct clamps or dust collection bag is not
properly clamped and secured.
2. Cylinder or funnel seals are loose or
damaged.
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 seals/gaskets.
