Make sure the feed dogs are dropped (or feed dog cover is on - I can't remember which way this machine works). The stitch length on the machine has no function so ignore it. (I set it to zero so the machine doesn't have to work as hard). Hopefully this is all that's wrong. If not, use a shorter setting for the stitch length on the regulator, oil the hook and move slowly and smoothly.
Good luck!

upper tension sets the lower thread tension (upper thread is what you see on the underside of the fabric). Bobbin tension is for the thread you see on the top of the fabric
SOURCE: my bobbin stitch is too tight on my Juki DDL
Hi LJ,
Look on the bobbin case, and see if there is a small screw. Usually that is the tension of the bobbin. You can adjust that until there is only slight tension on the bobbin thread.
Hope this helps
Joe
