Printed out the machine manual, and used the troubleshooting section to fix the problem, which was that the top thread was not properly routed to the needle.

Is the thread caught in gear in top of machine causing it to bind. If you refilled bobbin did the gear switch back completely or you have lost an o ring in bobbin rewind.

Uneven feed

machines can have single or double feeders. what type does yours have? feeding problems can usually be fixed by a good cleaning+ oiling of the feeder mechanism which regularly gets clogged with lint+threads/scrap threads. brush it out thoroughly with a stiff-bristled brush like an acid brush. apply 1 drop of oil to each feeder seen on the foot-plate. wipe excess oil off with a clean dry rag being sure not to get any debris from the rag caught in the feeder(s). other problem might be your bobbin tension. this is usually adjusted on the bobbin race with a very small screwdriver.

Machine will not sew, the thread is tangled and matted up on cloth side next to machine. I have re threaded, replaced bobbin. Still jams up.

I believe that the bobbin adjustment screw is loose, you need to hold the thread and see how fast it comes out of the bobbin, then tighten the screw until it just barely comes out. You may need to adjust a few times to get it right. If the bobbin screw is too loose, the thread feeds too fast and will jam up as you indicate.

Hope this is of some help

Bobbin tension is far to loose I tried adjusting the screw but no luck

Are you sure that it is not in your top threading instead of your bobbin? Try this test, totally rethread your machine with a fresh needle inserted (flat side facing away from you). Make sure that your presser foot is up (when threading and the first part of this test) , now pull on the top thread, it should move smoothly, then put the presser foot down, now pull the thread, it should barely move. This usually seats the thread in the discs.
You will find that bunching up of thread underneath is usually the opposite of what you thing, ie. top threading. Top thread issues are the bobbin causing the problem. Good luck

The thread on the top side of my material starts looping after 4-5 stitches. I've tried every number of thread tension, and even on 0 it loops on the right side of the material, not on the back.

Check the tension on your bobbin thread. When you hold it by the thread and let it dangle does it just drop down without any resistance at all? If so then you need to tighten it a bit. If the bobbin thread is too loose it can not pull the top thread down enough thus puts the loops on the top side of the stitch.

Machine jammed

Turn off the power and remove the needle and presser foot.

Open the needle plate and bobbin case and clean the area, removing lint and the jammed thread.

Make sure the bobbin case is properly in place.

There is a maintenance section in the manual to show you how to remove the bobbin case and clean the machine.

Install a new needle with the flat side to the back of the machine.

Rethread the machine with the presser foot up.

Make sure the thread from the bobbin is feeding from the bobbin spool in the correct direction and through the proper guides.
