I do the bare minimum when it comes to sewing machine maintenance. None of my sewing machines are under warranty so I don't take my machines in for service unless they are truly broken. I really good about cleaning out the lint in the feed dog and bobbin area after a big project and I will change my needle pretty often, but I don't oil anything on my computerized machines unless it's specifically mentioned in the owner's manual. The other morning I went on the internet looking for information on oiling my Martha, Bernina 1530. I found this youtube video on how to clean and oil a Bernina (not specifically a Bernina 1530) but a really good video and super helpful.
Link to video on how to clean and oil your Bernina sewing machine.
I had about 15 minutes before I had to leave for work so I did a little maintenance on Martha. I took my feed dog plate off, my needle out, and my bobbin assembly apart, brushed out all the lint, oiled the hook, and replaced my needle. The video recommends you oil your hook every 3 to 5 bobbins. I usually change my needle and do a full clean out about every 8 hours of sewing, but I never knew that I should oil my hook. I did notice that after I oiled the hook, the machine seemed to run quieter and smoother. It might be wishful thinking, but I think Martha is a little happier these days.
