I'm an only familiar with my Bessy fence. So, this may not help much. My cam lever actually bears on a steel "finger" that swings down to a position between the cam and rail. If I remove the fence and then put it back on, sometimes the finger does not swing down properly and then my cam lever will do what yours is doing. Since your fence is new, maybe paint or something is causing your "finger", if it has one, to stay up. Check it closely to see if there should be something between the fence rail and cam lever. Could you have a missing part? Do you have a parts diagram?
Oneida has a HEPA filter retrofit kit as well.
I want to saw there is a 3rd option but i can't remember it off the top of my head. If you don't put a cyclone in the system you'll want to clean the filter frequently. probably every other time you empty the dust bag.
