Learning to service Berninas
I would like to learn to service and clean my own Bernina 350. I'm not talking about cleaning and oiling the bobbin, which I do once a week or so. I'm talking about the yearly service that costs $100 at the Bernina sewing shops where they undo the machine and oil and clean all the parts.
Does anyone know how I might get trained to do this?
Is there a training program or videos about this?
I have noticed that sometimes shop keepers' husbands suddenly offer this service - where do they learn how to do it?
Thanks for feedback on this...
