Hello all, I have had this machine for years and love it, but it is pluckin my last nerve. Something has to be out of adjustment, as I sew the bobbin thread or bobbin area is jerking the top thread and balling up on the bottom of my material. I have noticed that it seems to work better if the thread tension is on 8 or 9. This seems to be pulling the bobin thread to the top so I tighten the bobbin tension. Then it starts again. Oh what an evil cycle. Help Pleassssssssssssssse. Thanks

Sounds like the bobbin thread is going in the wrong direction

OR

The needle isn't threaded the correct way.

I'll look for my instructions

Needle threads from front to back, the bobbin thread comes from the left going counter clockwise.

Check to see if the needle is inserted correctly...

If it has been several years since this machine was serviced, I would take it to the re[airman.

Sounds like lint in the groove of the bobbin race. Do you know how to remove the bobbin case from the machine? If you can get the case out use a toothpick to clean out the groove. You'd be amazed at the amount of lint that can get packed in there.

Did you figure it out yet?

I did take the bobbin case out, but did not see any lint in the track. I sewed for a few hours and it seemed to work pretty well. Thanks.
SadieMae It has been years since it was serviced. There are no repair men local. So I purchased a technical repair manual for this machine. thanks

Glad you figured it out. Remember if it ain't broke don't fix it.

Love the sheperd in your avatar.. I have had sheperds all my life and yours looks like mine. LOL
