I have a Ridgid 6 1/8" jointer model JP0610. None of the dust and woodchips fall down into the dust collection chute; instead they all blow back onto the infeed table. Even with a shop vac hooked up it didn't seem to make much difference. I won't rule out that I've somehow set it up incorrectly, but I don't think so. Does anyone else have this same problem? Is it a 'feature' of the jointer or is it something correctable. Thanks.
