My Delta mortiser has one and when new it would gently lift the
motor up when I let go of the handle if the chisel was not embedded into
wood. Today it only holds the motor at the location that I leave it.


Hmmm. Mine never lifted the chisel back up, buried or not. It was
never a concern, I just thought it natural to rotate the handle to
raise the head back up. The cylinder does the required job of holding
the head up. No worries.
