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 filters.
3. (g0601) Motor is receiving power out-of-phase.
disconnect the machine from power, then
swap any two of the incoming hot power leads
terminated inside the control box (see step 10
on page 30).
4. remove dust line from dust collector inlet and
unblock the restriction in the duct line. A plumbing
snake may be necessary.
5. relocate the dust collector closer to the point of
suction, and rework ducting without sharp bends.
refer to designing ducting system, beginning
on page 33.
6. process lumber with less than 20% moisture
content.
7. rework the ducting to eliminate all leaks. Close
dust ports for lines not being used. refer to
designing ducting system beginning on page
33 for more solutions.
8. open 1 or 2 more blast gates to different branch
lines to allow the velocity in the main line to
increase.
9. reinstall correctly sized ducts and fittings. refer
to designing ducting system beginning on page
33 for more solutions.
10. use a dust collection nozzle on a stand.
11. 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.
