It's been a few month since purchasing a grizzly 690 and I've been running dust collection since new but I seem to get a good bit of sawdust laying in the bottom of the cabinet. Is this normal? My dc have good suction but seems to leave a lot of dust in the saw. Also the bevel and height gears came with packing grease which now are covered in dust. There's no point in cleaning these right? The saw is kept in a shop outside and is only heated when im in there.
