On the Delta Table Saw this morning the blade was fully dropped and the hand wheel was freewheeling and not turning the shaft that would raise or lower the blade. After a bit of investigation the set screw on the handle was very loose. I looked on Talk for any known issues, didn’t see any, so I proceeded to tighten that down against the flat portion of the shaft. It appears to be working again however the mechanism feels tighter than I recall, though it’s been quite some time since I used it.
It’s perhaps A-OK however I want to report it in case someone with more experience than I could take a look, time permitting.
