[QUOTE=kellyer21;7514901]I'm a little confused. My bobbin is a drop-in, no bobbin case. Am I missing something?[/QUOTE
when you open the bobbin compartment to drop your bobbin in there is a black dish like thing you drop it into. That is the equivalent of a bobbin case. You need to remove it periodically to clean the lint out that gets packed under it or you will start to have all kinds of problems. There are a couple of pages toward the very end of your manual that show how to remove it and also how to put it back in correctly.
When you remove it you'll see that there are two screws on the side. One has a Phillips head and is probably painted green. The other has a slotted head. At the moment I can't remember which one it is that you use to Chang ether tension. But that is what I was talking about when I mentioned buying a second bobbin case. But that's not something you need to worry with at the moment.
