Started experiencing the same problem with blade height slippage today on my Dewalt DWE7491RS table saw that I've had for about two weeks. Nothing in the manual regarding blade height adjustment. I lower the blade to the lowest setting, raise it to the height I need, start the saw and can watch the height adjustment handle slowly turn counter-clockwise thus lowering the blade. No dust on the gears underneath as it is basically new and I don't see anything else that can be tightened really. Called the Dewalt number on the manual, but of course, they're closed and now I get to waste my weekend not getting any work done. Would love to know if this is just a faulty unit or if there is an actual fix.
