How do i oil my bernina 801? - Bernina Artista 180

There are two key points I suggest customers can do themselves to help lengthen the life of their machine. One is your hook and the other is the needle bar...
Hook - Open your bobbin door, removee the bobbin case/bobbin. On the upper left corner there is a small latch, push in the latch and your shuttle race ring will fall down forward. You can now remove your stainless steel hook. You need to keep this hook clean and the lip it fits back into clean and void of lint and debris. On the back of this hook or the "lip" that the hook fits back into apply a small amount of hook/sewing machine oil.
Needle Bar - Open up your head cover, the needle and needle bar clamp is attached to a long stainless steel rod that travels vertically inside your head. All sewing machines have a needle bar that looks like this. This bar travels thru two brackets attached to the frame of the machine. Rotate your handwheel and clean the needle bar well of debris. Rotate the handwheel so that the needlebar is in it's highest point and apply a small amount of oil to the upper and lower bracket of the frame, rotate the handwheel so the needlebar slides back down and therefore lubricating it and the inside of the brackets.
Hook oil or sewing machine oil is relatively inexpensive from all quilt, sewing machine, repair shops. Be sure to take your machine in a minimum of every three years for proper cleaning and lubricating of all the other parts (This is of course for average home sewing machine use 8hours a week)
