Bread-Bakers v097.n051.11

After six years of regular dependable use my Welbilt ABM finally bit the
dust.  Replaced it with a Zoji which, except for one little problem, I'm
very happy with.  Problem is the paddle is very difficult to remove for
cleaning.    Is this unique to my machine or has someone else experienced
the same problem?  Managed to remove it once with the aid of a pair of
pliers.  Applied a little vegetable oil to the paddle and shaft before
replacing it, but that didn't help.  Any suggestions? 

TIA,
Griff
