Mine is a D1-5 direct mount and has the same indication on all three screws.Exactly. That is a warning label addressing the issue of running a screw-on chuck in reverse.

Only direct mount chucks have this insignia. I don't think Rohm makes a direct mount screw on chuck.I'm leaning for the sign to mean do not run it in reverse with a threaded spindle mount.
That's interesting. I have three Rohm chucks with D1-5 back plates. None of them has that marking on them. I have seen a very similar marking on another chuck that was a screw-on chuck. Can't remember the brand, but I'm thinking it was an older Cushman or Skinner chuck.Mine is a D1-5 direct mount and has the same indication on all three screws.
