How do I stop my lower looper unthreading?

Best course of action when a thread breaks or comes unthreaded is to completely remove all the thread from the machine and rethread from the beginning--RAISE the presser first, make sure each thread is threaded in the proper order specified in the manual, make sure that each thread path is correct. Be sure to pull at least 6 inches of thread tail through the loopers and needles and pull them toward the back of the machine so they are under the presser foot before beginning to stitch.

NOTE: raising the presser foot releases the tension disks so the threads will slip into the tension disks. It is always helpful to give each thread a little tug below the tension disk to ensure the thread is seated all the way.

Baby locker has no stitch at all ive thread it just as shown on diagram , im so frustrated with it

Remove all the thread.

RAISE the presser foot. Then rethread from the beginning making sure you are following "each" thread's steps and that you are threading each thread in the "order" specified in the manual. (If any steps are missed or the threads are not done in correct order, the machine most likely will never work! Sergers are finicky machines!)

For most sergers, the lower looper thread's "final" step is to lay "over" the top of the upper looper before begin pulled under the presser foot.

Also, if a thread breaks or comes unthreaded, the best policy is to unthread and start over. Simply rethreading the one thread will "Not" work!

If you still can't get it to work, you might take it to a Babylock dealer and have them look at your threading. Could be something is wrong with the machine other than the threading.

Why does lower looper thread keep breaking?

Usually, thread breakage is due to incorrect threading. When a thread breaks or becomes unthreaded, the best policy is to remove all the thread and rethread from the beginning. Be sure to RAISE the presser foot before threading to allow the thread to seat properly in the tension disk. Also, be sure to thread each in the order specified in the manual or it is unlikely your machine will ever function properly.

After automatic thread cut the needle comes unthreaded

you need long thread tails, of 3 to 6 inches for the top & bobbin thread so the needle doesn't come unthreaded,
also pull the thread behind the needle before you start to sew

Bought for a child, ls2000 the needle unthread

Make sure the needle is installed correctly. With most sewing machines, this would be with the flat side of the needle shaft facing the back of the machine.

You may be able to find a free download for a manual at Brother's website.

Most machines need to have the thread extend to the back of the machine in order not to come unthreaded.

Sewing machine either breaks thread or comes unthreaded every time i try to sew.

Your threading is not right, totally remove your thread and rethread according to the manual directions and dvd. If, you still have problems call Singer at 1-800-4singer

My thread often becomes unthreaded from the part that raises and lowers the needle causing the thread and fabric to jam up

Your needle should not come unthreaded in the middle of sewing.. if it does, it is because the thread breaks. this can be a simple tension problem or brittle thread.

if you are talking about at the beginning of sewing that the needle comes unthreaded, then you should just pull out 6-8 inches of thread through the needle before putting your fabric under and begin sewing.

i hop that helps.

Lower looper

It is impossible for a looper to come unthreaded if you are holding one end and the other is still feeding off the spool. Somewhere a thread broke - must be either the upper looper or the needle. Try completely re-threading your machine. Many machines have an "order" they prefer to be threaded. Try starting from the right tension guide and work to the left.
