You can do it! Do you still have your manual? It will show you a pic of the bobbin case, if not...take your bobbin out. Then you'll see the little part it fits in, there should be maybe a little clip on the side of it that will slide towards the back of your machine, just push it back and get the bobbin holder out. If there's no clip to hold it in place then just rotate the case to the left or right and it will come out of it's "groove" that it fits in. Then get all the lint out, etc. put a little sewing machine oil on your finger and lightly apply to the inside of this piece. Oil same way on the bobbin case itself and put it back in place. Rotate it just a little so it's in the groove again, put in your bobbin as you normally do and try sewing. It really is not hard just take your time and pay attention to how it goes together. Way cheaper than having repair man or buying a new machine when you probably don't have to at all, well......unless you want a new machine. Now that's another story
