Lower right thread (green) keeps coming out of its eye!

Following the 'map' I seem to be threading the overlocker correctly, but just today the lower right (green) thread keeps coming out of its final eye.  This stops it from working.  It's odd, 'cause the thread continues to feed through, and appears unbroken, HELP!

Difficulty to do needle threading on S4D overlocker

Sergers are absolute "bears" when threading compared to sewing machines. If/when you get frustrated, walk away. It took me the majority of one day before successfully getting my first serger threaded properly. Using four different color threads is also helpful when learning the serger--especially when it comes to adjusting the tension.

It is very important to pay attention to the order the threads are threaded, as well as making sure the thread path for each is correct. (Consult your owner's manual as different brands will look different.) Most machines require that the upper looper be threaded BEFORE the lower looper because the lower looper thread will cross OVER the upper looper thread as the final step before going under the presser foot.

ALWAYS RAISE the presser foot when threading!!! This releases the tension disks.

Also, when threading through the tension disk, be sure to give the thread an extra little tug to make sure the thread seats firmly in the tension disk. (Grasp the thread just below the thread stand with one hand and then grasp the thread below the tension disk with the other hand and give a little tug--sometimes it will make a little popping noise when it seats.)

Start out with the tensions set at the midway point. From that point, you can test your machine to make sure it is serging properly. Then you can adjust the tensions to suit you or the project you are making.

If the either looper thread breaks or pulls out, remove BOTH looper threads and rethread from the beginning!!! Trying to finagle threading of only one thread will most often result in a machine that will not operate correctly. Just bite the bullet and rethread both threads (in the order specified in the manual).

I seem to have trouble using the tweezers to thread the looper eyes, so I use dental floss threaders instead.

One more hint: NEVER pull the thread out of the machine by pulling it UP through the machine. This could damage or wear the tension disks. Always clip the threads just below the thread stand, RAISE the presser foot, and then pull the clipped threads DOWN through the looper eyes and needles.

Be sure to clean and oil your serger frequently. This is very important to get the best performance from your machine. Use only fresh oil recommended by the manufacturer and apply only a couple drops each spot.

Bernina 335 serger won't sew/overlock. carefully rethreaded the serger but that hasn't helped.

The 335 has a two thread chain stitch (stitch type 401), and the overlock side (right needle side), is a three thread plain overlock. If you are describing the plain overlock as the problem, I would first suggest the following in re-threading:

1. Thread the upper looper
2. Thread the lower looper
3. Thread the needle last (important)

If the needle threaded, you cannot re-thread the lower looper without breaking the thread.
In order to thread the lower looper, the lower looper must pass by the needle thus picking up the needle thread. So, instead of threading the lower looper thread underneath the needle thread, the looper would be threaded on top and cannot sew without breaking the thread.
Make sure that the threads are bedded between the tension disks. Check this by stretching the thread fore and aft of the tension disks as well as visually noting that the threads are not accidentally threaded behind the disks. You can also loosen the tension disks when threading so as to allow the threads to bed deeply between the disks.
Please reply with your observations.

Thread lower looper on Elna 624 DSE. I have manual, still can't do it.

are you using a wire threader or tweezers to thread up? also some overlockers have a slide mechanisim on the looper so you can get to the eyelet, not familiar with this model but your manual should show the threading method. I usually turn the flywheel so the lower looper is all the way to the left and thread up the lower thread carrier, then turn flywheel again to move it to the right, then using the wire threader, I hook the thread from the left and bring it over to the right side, then thread up the looper eye. Hope that makes sense to you

Correct threading for 4 th. Juki ind. overlocker

Overlockers and or Sergers are ALWAYS threaded the same way. Upper looper, Lower looper, right needle, left needle. If you have a model number for your Juki we might be able to find you more information.

The best way to figure out tension problems is to thread each thread in a different color so you can determine which thread is giving you problems.

These machines can be frustrating and EVERY time the thread breaks you MUST start the threading problem from the beginning... upper looper, lower looper, right needle left needle.

My Janome 204d Serger won't form a chain stitch. It is threaded correctly. I have changed the needles??

I would suggest that you check the needles again, make sure they are both fully up into the needle housing. Also they should be at different heights in order to form the stitch sequence.

It is important that you thread the loopers first in the sequence shown in your manual, then the needles. So you may need to recheck the threading again and make sure the threads are in all the eyes correctly, especially the lower looper. Also some overlockers, have a sliding eye on the lower looper for ease of threading, if yours does, make sure it has been slid back to normal operating position.

When you have checked the threading up, take all four threads under the raised pressure foot and make sure that the upper looper thread and lower looper threads are not crossing over each other. Lower the pressure foot and try to chain off again.
I hope this helps you to resolve the issue.

I have been using my serger then suddenly it would cut and not serge. I am still unable to thread the "green" right hand threader.

Apparently either you have no needle threaded to lock the stitch or both loopers aren't correctly threaded. You must thread your UPPER looper first (don't know what color yours is), LOWER looper next, RIGHT needle next and last the LEFT needle if you are using the 4 thread overlock stitch. It sounds like you are having trouble with your lower looper. Look for the lower looper threader to help you thread it. Your manual should show you a picture.

I've lost my manual and video need threading info

One of the most common mistakes with overlockers is that the threads must always be threaded in order. So if you sew about 1 inch and the thread breaks try unthreading the eyes of the needles rethread the looper and then rethread the eyes of thew needles. If not you will get the same result of sewing about 1 inch and it will break again.

Threading the bernina 1300DC serger

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.

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.
