Question about Kenmore 16622 Mechanical Sewing Machine

1 Answer

Thread keeps coming unthreaded in the machine

I have a kenmore 16622 mchanical serger. The thread on the green, keeps coming undone. The thread will literally come out of the last hole of the threaded part. After threading the machine entirely, I am not sure where all the threads should lead before atempting to serge on a scrap cloth. This is getting a little fustrating, as I have threaded the machine countless times. How do I solve this reoccurring problem? Please Help.

Re: Thread keeps coming unthreaded in the machine

The green thread needs to go under the brown thread between the clip and the brown needle. I had this problem too.

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.

Instructions on changing thread tensions on a Mylock134

Probably the best thing would be to consult the owner's manual.

BEFORE you thread the serger, RAISE the presser foot so the threads will seat properly and the thread will slide easily. Be sure to thread each thread in the proper ORDER! (Usually upper looper is first, lower looper second and the thread tail should always end up laying OVER the top of the upper looper before passing under the presser foot.)

It is also helpful to use different colors of thread so it is easier to tell which thread's tension needs adjustment.

Sergers require varying tension settings depending on the type of stitch and the appearance you prefer. To achieve the standard stitch setting on most sergers, start out with all the thread tension settings at the midway mark between the high and low numbers. Then test and adjust from there.

Verify with the owner's manual that you are threading everything correctly and not missing any steps. If any thread happens to break or come unthreaded, it is usually best to unthread EVERYTHING and start over from the beginning. (Sergers are very finicky, so if you are frustrated trying to get things to work, the last thing you will usually try is unthreading and rethreading from the beginning.)

I have a singer ultralock 14u34 - the right needle thread keeps coming undone. anyone have a fix for this??

"Coming undone" What do you mean? Is it breaking while sewing? Is it too short and is slipping back through the needle?

If it's breaking, try changing the needle. If i's slipping back... give it some length when you thread.... and at the end of a seam Run it out... 10 inches before you cut it off close to the fabric. That little bit of thread waste will make you feel much better about your serger.

Serger thread breaks

1. Is the serger threaded correctly?

2. Is the needles inserted correctly?

3. Is one of the needles bent or damaged?

4. Is the tension adjusted too tightly?

5. Is the tension adjusted to accommodate thickness of thread being used?

6. Are you using inferior quality thread?

7. Is the thread feeding off the cone/spool freely?

8. Is the needle size correct for the type of fabric being used?

9. Are the needles being used the correct one for the serger?

10. If all of the above suggestions don't help then the serger needs to be checked for a timing problem at a sewing machine repair shop.

try checking the tension dial and loosen it just alittle
check your manual for directions on tension
make sure the thread pulls smoothly from the needle
also make sure the thread tails are long enough to be pulled
behind the needle before serging.

#1 thread keeps coming out on the 3/4 thread kenmore serger. How do I fix this problem?

try rethreading the needle & keeping thread tails of at least 4 to 6 inches that you can keep pulled behind the needles

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.
