Are you by any chance pulling on the threads when the needle breaks? If it's an older serger, I wonder if the timing has gotten off because of the needle breaks. Timing would need to be fixed by a technician.
I would probably change both needles, completely unthread the machine, clean and oil it, and then re-thread from scratch. For the tension knobs, I put them on the lightest tension when threading (0-1) to make sure that the thread seats properly between the tension discs. I am careful to change those settings to the middle (3-5) before doing a test sew.
It isn't just the tension settings that affect the loops. The stitch width (moves the knife left and right) will affect how the loops hang off the edge. Also, you need to check if you have it set for a narrow bound hem.
Prism99, I've had the machine for about 3 years now. And just in the last year have taken it out and begun using it again. It was working fine, minus the needle breaking and tensions being off. I guess I just really hate to thread it, and really just didn't want to play with it. My mom owns a serger, and that one works like a dream, she has owned that one for 10+ years, and never had a problem with it. It's also a singer, just a different model. I will have to take it in to a tech then, b/c I know I'm not pulling on the fabric. That was my initial thought, but then I slowed my pace, and tried sewing the chain and it still breaks the needle. I've replaced both needles when the right one breaks, and have unthreaded and rethreaded the machine upteen times, but still have the same issues. I really do guess it has to be seen by a professional, and get some help. Thanks for your reply, I'll see if the tech at my local sewing shop can help if not, i'll try Hancocks.
Hugs,
Wanda
