Your sewing machine is a machine. It needs to be oiled where metal rubs on metal. They tell you that it doesn't need to be oiled, so you'll have to take it in to be serviced. It's a marketing ploy. You can oil the take-up area yourself. Only use clear "sewing machine oil," not 3-in-1 oil or WD-40. On some Janome machines, you can't open the machine to get into the take-up -- there's no service panels. However, you can oil through the slot. Shine a flashlight from the top, and put a drop of oil on each joint, and on the needle bar. If that doesn't take care of the squeak, it may be in a different spot. Or the squeak is happening because there's old oil that needs to be removed. In either of those cases, it's best to take it to the shop. Janomes aren't made to be easily opened and serviced.
