Before I go digging over at the old woodworking machines site, can anyone tell me how difficult it should be to raise and lower the arm on a Dewalt GWI RAS? I don't see anything that clamps to "lock" the height, and it takes a manly effort to raise and lower the arm (had to raise it to extend the fence, then lower it back). I hit it with a little WD40 and that may have made a slight improvement, but not much. Is there a clamp someplace that I've overlooked (I looked through a PDF version of the manual and didn't see one)? Is this a hint that IO need to tear it down, clean, and lube everything good?
Thanks
