Easy Instructions for Threading Bernina Serger eHow

Start out with NO thread in the machine.
ALWAYS RAISE the presser foot during the threading process.
When threading through the tension guide below the thread tree and through the tension disk, give each thread an extra little tug to make sure it is completely seated (it may even make a little popping sound when it seats).
ALWAYS THREAD each IN THE CORRECT ORDER (upper looper first, lower looper second, then the needles). When threading the lower looper, ALWAYS FINISH with the lower looper thread draped OVER THE TOP of the upper looper.

If a serger looper thread breaks, it is most often easier (and much less frustrating) to unthread the entire machine and start from the beginning. Trying to fish a thread through only works about 1% of the time, Just bite the bullet and do it!

When unthreading the machine, NEVER pull the thread UP through the tension disks! Instead, cut the thread below the thread tree, RAISE the presser foot and pull the cut threads down and out.

Third thread--is that the upper looper? Remove all the threads from the machine. Clip them below the thread tree, RAISE the presser foot, and then pull all 4 threads down through the needle. (Never Pull Up!!)

ALWAYS RAISE the presser foot.
Rethread beginning with the Upper Looper, then Lower Looper, then the needles. Be sure to ALWAYS thread in this order!! (On most newer machines, when threading the Lower Looper, always finish with the Lower Looper "draped" over the top of the Upper Looper.)

If a thread breaks, remove the threads and start over from the beginning as trying to fish a thread through the existing threads very SELDOM works.

Verify each thread path is correct.

When threading each thread and to insure the threads are seated in the tensioners, give each thread an extra little tug when going through the tension disk.

Be sure to oil your machine frequently to keep it operating smoothly!

Usually it means it is not threaded correctly. Remove ALL the threads from your machine. Be sure you RAISE the presser foot when threading. ALWAYS thread in the correct order. Verify the thread path for each is correct. Check that the threads are seated in the tension disks--give each a little tug when going through the tension disk. Be sure that the thread tree is extended to its full height. Check that the lower looper threads are not set too tight. Also, always use fresh thread--no old stuff from grandma's sewing basket.

ONE MORE TIP: When a thread breaks, you will usually find it less frustrating to unthread the ENTIRE machine and start from scratch. Trying to fish a thread out of sequence will most often times end in failure.

probably need a adjustment, you may have to have the looper checked

Assuming this is a serger. The second thread from the right would be the lower looper. Nine times out of ten, when the looper thread breaks, it's because it is threaded incorrectly or the tension is set too high.

It is generally recommended that when a thread (especially a looper thread) breaks on a serger, you should remove all the threads and start over from the beginning (yep, that sounds painful but it is better to just bite the bullet and just do it rather than fighting it and never getting it threaded right). Make sure the presser foot is raised throughout the threading process, give each thread an extra tug when going through the tension disk to insure it is seated in the disk properly, follow the threading order (usually upper looper first, then lower looper) and the thread pathway is correct for each thread (no guides are skipped and thread is not wrapped around something). The last step of the lower looper threading is to make sure the lower looper thread drapes over the upper looper before being pulled under the presser foot and toward the back of the machine.

Set the tensions to the midway point between high & low numbers before testing.

Thread breakage is usually an indication that the machine is not threaded correctly or the tension is set too tight.

As a reminder, if a thread breaks, save yourself some (lots!) frustration and rethread every thread From The Beginning. Rethreading only the broken thread will usually just lead to it breaking again. Sergers are finicky and must be threaded in the correct order. Also, Always raise the presser foot while threading. Your thread breakage is occurring with the lower looper. Be sure that you are threading every guide and give it a little tug going through the tension disk. Usually, the last step is to drape the lower looper thread over the top of the upper looper before it is pulled back and under the presser foot. Be sure to initially set the tension at the midway point between the high & low numbers.

My serger is still not working properly trhread still breaking lower and...

does this Serger have a moveable threading part on the lower looper and if so, is it in the correct position? It sounds like the clip is in the wrong place if it is catching the thread, so this could be the cause if so.

If not, then I would suggest that you recheck the threading, and thread in sequence, top looper, bottom looper, then needles, checking all thread loops are being used in the thread path, review carefully using the manual's threading diagram.

If you still can't resolve the issue, then take it in for a service, it is possible to knock the loopers out of time and if so, you'll need a technician to rectify.

I had the same problem with the blue thread- it would sew and inch then pop- mine worked wihtout breaking after I re threaded in this order: green, blue, red then yellow

These things are always complicated when you try to write them down, so I suggest a call to your local Bernina dealer to arrange a quick lesson on how to do it.

If you can go back to the dealer whence it came, so much the better..........perhaps you could go in and buy some things you need and then as you are leaving, make the enquiry with the machine in your car, they may be able to show you how to do it right away......building relationships is a very good way of feeling comfortable about asking for help.

Also..........
If the manual diagram is too small, a local library or stationery supplier should be able to magnify a photocopy for you to see it all more easily.
