Our service technician (DR. Dan) takes you through the simple process of cleaning and oiling a Bernina rotary hook sewing machine. If your machine doesn't have a rotary hook, look for our video for your machine.
Thanks for showing this video demo to clean Bernina machines. I have a new B380, is it done exactly the same way? Why should the bobbin thread tail be cut on the inside of the bobbin door after cleaning, is it necessary?
