#37 in the list as of me posting this. You can get a CD version too but you'll just pay more and wait longer for the same thing. Once you have it print the manual (preferably both sides to keep it small) ang you'll have it. You can also peruse eBay to see if anyone is selling a manual but I doubt that will yield regular results. The machine looks to be pretty basic and standard but it's best you have the manual to get the most out of the machine. Also be sure to check the cleaning and lubrication section and go through the process so that the machine is in top working order before you put it into regular use - saves a lot of headaches.

I have changed stabalizers and the type of bobbin thread i am using (invisible poly) and it seemd to have solved the problem. Note: wind invisible thread very slowly and carefully it is like fishing line

This could either be due to the bobbin being wound too loosely, or the tension on the top thread is too loose. This just happened to me the other day, and I thought it was the bobbin thread, but then I put another bobbin in with a different color than the top thread (this is a huge help in diagnosing thread issues), and I was surprised to find that it was actually the top thread that was a big loopy mess on the underside of the fabric. I fixed it by tightening the tension on the top thread (quite a bit), and everything was fine.

The problem is never the bobbin when you have this problem. It's the top thread. Take the thread off the top of the machine and rethread the top. Make sure the small tension dial is on 4 or 5 (the larger dial on the front left is for the pressure on the foot, not the thread tension.) After you thread the machine, put the pressure foot down but NOT on the thread. Then pull gently toward the back of the machine. When you do, the needle should bend slightly backwards before the thread comes through the machine. If it pulls with no resistance you could simply have "fluff" or remants of thread between your tension discs. If you do, put the dial on zero and using an old needle, clean between the discs and try threading the machine again with the "pull test" I described earlier.
No tension on the top of the machine, lets the bobbin tension win and it pulls all the thread to the bottom of the fabric.
