The piston trimmer is extremely intolerant of any oil.
In the early days of the 10811, they encountered a bad aging
problem that we traced back to the piston trimmer. It
turned out that the trimmer was lubricated with some oil
that slowly migrated. The fix was to go to a different trimmer
that didn't have oil lubrication.
