Instructions for threading - Sewing Machines

Most often, the problem either has to do with mis-threading or the machine has been knocked out of time. (It took me an entire day to thread my serger correctly the first time.) Start out with no thread in the machine. Follow the instructions "exactly." ALWAYS RAISE the presser foot when threading and be sure EACH thread is threaded in the correct order! Another helpful hint is to give each thread an extra little tug when going from the thread tree to the thread dial. This helps the thread seat completely in the tension disk.

Your machine is either not threaded correctly, or the individual threads have not been threaded in order. Be sure to ALWAYS RAISE the presser foot when threading the machine. You must follow the instructions exactly or the machine will most likely never work properly. Can you at least get a training class on your machine? A class is indispensable, especially when it comes to using a serger.

Even if it is not the same model, these instructions may be helpful.

Tutorial for threading overlocker

Make It Handmade Threading Your Serger or Overlocker

Need manual for an empisal 754D overlocker can get the tension right and...

It could be the top thread is the problem. Might try removing all the thread. Consult the owner's manual for threading instructions. RAISE the presser foot BEFORE threading the upper thread so the thread will seat properly in the tension disk. Re-thread from the beginning carefully following the instructions--do not miss any spots or thread guides.

If top thread is still creating a mess of loops under the fabric, try tightening the upper tension. The tension is ideal when both upper and bobbin threads meet in the middle of the fabric.

There are manuals for several of the submodels of the Singer 81 class here: http://parts.singerco.com/IPinstManuals/

If you've threaded the bobbin per instructions... then make sure your needle isn't damaged, bent, or dull. Also make sure the needle is seated fully and correctly oriented into the needle bar.

Open the font of the serger and the instructions will be printed on the serger or on the door.

Raise the presser foot and set the tensions to zero when threading.

Turn the hand wheel so the upper looper (curved one) is at it's highest point and thread it first, and then the lower looper.

With some sergers you must thread in a certain sequence. This should be indicated in the instructions on the serger.

Set the tensions back to normal ( 4 - 6), lower the presser foot and run a length of stitching to see if the threads are knitted together as they should before you start serging your project.

you do need to provide more details.  start here - get a fresh spool of high quality all purpose thread such as Coats and Clarks or Metrosene thread, fill a fresh bobbin, install a new size 11 needle.  Follow the threading instructions even if you've threaded the machine a million times, read the instructions again.  try sewing on some basic cotton fabric.  You'll be able to determine if it's the machine.  Breaking thread can be the thread (it does get too old and fragile), the needle, the incorrect needle for the fabric, the wrong thread for the fabric, and a host of other things.  So try that and tell us more if that doesn't work. 

It looks right but its not. Try looking on the internet for threading instructions. The bobbin winds in two directions, I have never saw a Bernina but I have 2 new machines and the thread goes in and then threads back to the left. Its hard to describe. But if the bobbin isn't right it will not pick up the thread. Write to Bernina for instructions. There are websites that have the directions for free.
