X. Troubleshooting
Motor Overheating
The motors internal circuit breaker will trip if the motor is overheating.
Air leaks between the collector and dust bin
- The lid of the dust bin and the cyclone must be in place and sealed when operating the dust collector.
- Make sure flex hose is not torn and the hose clamps are tight.
- Check drum lid; cover should have a foam seal and be well seated.
- Check for holes or leaks in the dust bin barrel.
Caused By:
Motor not properly wired. Check wire connections.
- Check motor rotation - See wire diagram
Check breaker box. Make sure power supply is 110V if wiring 110V or 220V if wiring for 220V.
Poor Dust Pick-Up at Woodworking Machines
Caused By:
Check length of duct runs and duct diameters compared to ductwork design guideline.
Make sure all ductwork is sealed. Large air losses will occur even through small cracks in the
ductwork. Use silicone, duct tape or duct mastic compound as a sealant.
Check for air leaks between collector and dust bin.
Close all unused blast gates at your woodworking machines.
Examine hood design for weaknesses according to the ductwork guide.
Check for a restricted pipe, too small a hood port or too small a branch line. See branch line
diameter chart in ductwork guide.
Be sure that your filters are clean. See filter cleaning directions.
Filters filling with large chips and excessive dust
Caused By:
Air leakage between cyclone and dust bin. Cyclone and dust bin must be air tight. Even small leaks will cause
poor preseparation in the cyclone.
- Check drum for any leaks.
- Make sure drum lid forms a good air tight seal with the drum.
- Check flex hose connection. Make sure hose clamps are tight. Seal with silicone.
- Make sure dust bin has not over filled. Dust bin should be emptied before the dust reaches
top of the container.
- Make sure clamp around cyclone is tight and sealed with silicone.
- If there is not enough air entering system, open more blast gates.
- Minimum 4 diameter pick up at tool location. Less than 4 will restrict air flow into collector and
will increase filter maintenance.

Improper motor rotation - Running backwards will reduce suction by 30%.
Excessive vibration
Caused By:
Loose mounting bolts, set screws, bearings or couplings.
Bent shaft due to mishandling or material impact.
Accumulation of foreign material on the fan wheel.
Excessive system pressure or restriction of airflow due to closed blast gates.
Inadequate support structure.
