I hear your pain, believe me. I don't have your problem, mine is the simple 3-thread hem and that's it. I will try to help you with your situation though. Have your threaded your upper or lower looper first? You have to thread the looper on the left, not all the way to the right. The upper looper (the one on the left), then the lower looper, then the needles last. Let me know if this helps.

Thank you for contacting the Singer Sewing Company. Below are threading instructions. It appears that the threading may have started wrong. If the below steps do not work, please visit our website at singerco.com to locate a service center near you.
Be sure to follow these simple steps when threading your serger.
- Make sure that the looper cover door is closed correctly; your serger will not sew if it is left open.
- Make sure that you unthread both needles when threading either the upper or lower looper, otherwise the thread will keep breaking or the looper will become unthreaded.
- You must thread the upper (orange) looper first, then the lower (yellow) looper, then the right (green) needle and then finally the left (blue) needle. It is extremely important that you follow this order when threading your serger.
- Make sure that you are using the same brand and same size spools of thread on all four spool holders. Manufacturers use different twisting methods, which will affect how your serger will stitch.
-The color black is one of the most difficult colors to work with; this is caused by the chemicals used when dying the thread. We recommend using a deep navy or a dark grey in the loopers rather than the color black, this very often will eliminate skipped stitches, or the loopers becoming unthreaded. You can use black in your needles however.
- Make sure that seam width finger is positioned at "S" for standard sewing; this is illustrated on page 57 in your manual.
- Make sure that the differential feed is positioned at 1.0; this is illustrated on page 49 of your annual.
- Make sure that the width adjustment knob is set a 4.5 if you are sewing with 4 threads, 3.5 if sewing with 3 threads, and at "R" if doing a rolled hem. This is illustrated on page 47 of your manual. The width is adjusted by turning the small dial to the right of the lower knife on the front of your serger.
We have step-by-step threading instructions on our website; please take a few minutes to review these at www.singerco.com, click on "Sewing Resources” and then “Operation Basics”. Next scroll down to the threading information for sergers.
