![]() Plastic is only used on the exterior of the serger.) (Some techs charge $100 to $200 for this kind of a service, but considering the hours that can go into cleaning and fixing a machine in this deplorable condition, is definitely worth it! Notice that while this serger was assembled in China, for Bernina, it is all metal mechanical working parts, inside. Normal serger manuals do not give you instructions for a deep oiling, like you would normally pay a service technician to perform for you. There are 2 separate videos, showing the inner metal parts. These are photos of the Bernina 800D serger, with all of the plastic covers stripped off, it shows you the MANY inner working parts, which require oiling, to keep it running for years. ![]() (I paid $30, just because it was a Bernina and had the pedal and cord, even though we had no idea if it ran at all, and turned out to be frozen solid.) For a $20 serger, you kind of expect this kind of mess. This isn't actually a large amount of lint, it looks so nasty, due to the rust! This is before I cleaned it out. Time, of course, also causes the old oil to dry up, and turn into a lacquer, or glue, which can also freeze your sergers and sewing machines, into solid blocks of metal. Lint absorbs the oil and lubricants from the metal, and then holds moisture it absorbs from the atmosphere, causing rust. Lint is the enemy of sergers, left inside your serger, especially if you live in a humid environment, it will cause rust to form. ![]() ![]() ![]() My hubby helps me fix sewing machines and sergers, it is how I have good sewing machines, that I couldn't otherwise afford! Note, I had not put the front door back on, after timing it, when I sewed this stitch sample, and took this photo. After repairs and oiling, test stitching, shown with 4 different colors of threads, shows that it works correctly, that the timing is right. ![]()
