The bobbin area should be cleaned and oiled about every 3 hours of sewing time. If you look inside the bobbin door, and turn the handwheel, you can see that one part of the hook turns, and the other is stationary. You want to put a drop of oil between these two parts. It's a good idea to clean and oil the take-up area and under the machine about every 6 months. I believe there are 6 screws in the bottom, plastic tray. With the plastic tray off, you can use a can of air. (I know someone will be upset with me saying that, but the particles have a place to go with the tray off. We use an air compressor at the shop.) In the take-up area, put a drop of oil on each joint. Underneath, put a drop of oil wherever metal rubs on metal. The nylon/plastic parts don't need oil.
