I am working on a 20 inch Powermatic 290HH planer about 7 years old. I am getting chips falling down onto the feed table while in use. I have messed with the plastic chip cutter. I am starting to think it is a suction volume problem. Recently rotated the cutters (132) and cleaned and adjusted the rollers. Feed and cuts are nice but the chips not being extracted in an issue. Any input would be appreciated. Thanks in advance, Kevin
