Ladywingnut- I also have the 770 and love it.
They told us to oil under the plate in the red dot when i took the classes, now Bernina is saying not to.
When i was in the LQS i asked and was told that there had been many complaints of oil getting on quilts so now they do not recommend oiling as often or even at that site. She recommended continuing to oil just as often and to just run a scrap fabric under needle before quilt.
Isnt it silly that companies have to change policy due to some folks that seem to lack basic common sense?
It’s not a machine issue if you overfill the oil and then get oil on your project!
