Sewing machines, like every tool in a shop, work wonderfully when they are maintained and cleaned on a regular basis. Although all sewing machines are set up a little differently, the basic elements are pretty much the same.
In this Instructable I am going to show you a simple way to keep your machine working in tip top shape.
Be sure your presser foot and needle are raised as high as possible so you don't damage them. You could also choose to remove them completely if your presser foot or needle don't lift out enough for you to reach all the parts you need.
Next, unscrew and remove the needle plate. Your needle plate may have more screws, so make sure you get them all before trying to lift it.
