Unplug your unit before servicing or cleaning. Keep the top vents in the cowling clean. These are for both exhaust and incoming cooling air for the motor.
Filter Pulse Bar Cleaning
The Pulse Filter System helps to unclog the filter for improved airflow and performance. If air flow is not restored after pulsing, check for clogs and clean filter. (Review Cleaning the Filter and Troubleshooting Sections).
- Pulse your filter regularly—including multiple times per day when collecting fine dust—or when you notice decreased airflow. Frequent pulse cleaning of the filter will keep your performance optimal.
- While the unit is running, close the Blast Gate on the inlet of the Cyclone. Once closed, push down the Pulse Bar extending out of the cowling, past the initial resistance, and hold for a few seconds then release the Pulse Bar. Repeat five times.
- Open Blast Gate to resume normal operation.
Cleaning the Filter
We recommend pulsing the Filter regularly - at minimum before you start to work and when you are finished for the day. If performance has decreased and pulsing does not restore airflow, the Filter should be replaced.
- Wear a dust mask and eye protection.
- Turn off and unplug the dust collector and wait for the fan blower to come to a complete stop and for the dust to settle.
- Unlatch the Ring Clamp (D) at the base of the motor section and allow it to hang freely. Remove the motor section and set aside.
- Use a hand-held, compressed air nozzle with a pressure between 30 to 60 PSI to blast air along the filter’s exterior pleating. Hold the air nozzle at a 20 degree angle and at least 6” away from the filter; closer blasts will damage the filter material. Direct air out and away from anyone in the area. Do not use this method when any hazardous material has been vacuumed up.
- Check to make sure filter is in good condition with no torn media or cracks or tears in the seal. A broken filter can leak material into the motor and cause severe damage! You cannot operate the system without a proper filter in place. (See Accessories page for the replacement filter part.) Operating without a sufficient filter will cause severe damage to the motor and will void the warranty!
Note: To help see damage from the outside, shine a flashlight from the inside. If the filter is removed after it's been in service for some time, the gasket may no longer return to it's original thickness. In this case, ensure enough gasket thickness remains for proper sealing to prevent dust from escaping. - If the filter isn't in good condition, remove the Filter (C) by removing the four 5/16-18 Nylock Nuts (G11) and the Filter Hold-Down Ring (B) by sliding it over the filter. Dispose of the old filter in the same way you would dispose of the dust you’ve been collecting.
- Center new Filter (C) over the center of the Cyclone (E)and place the Filter Hold-Down Ring (B) over the Filter (C) and re-secure using the four 5/16-18 Nylock Nuts (G11.) Tighten hardware so that the Filter's pre-installed foam gasket is firmly compressed (by roughly 50%). DO NOT OVERTIGHTEN.
- Replace the motor section and re-latch the drum clamp around the motor section.
