Question about Bernina Sewing Machines

2 Answers

On my overlocker, the bottom two threads keep breaking.

I have a Globe Lock M-34 overlocker. The machine is correctly threaded and tensioned as far as I can tell, it sews a normal looking 3 thread overlocking stitch for a while. Then one of the bottom threads breaks. Both of them break, but not usually at the same time. They look like they're snapping cleanly or being cut. I've tried nylon and cotton thread with the same result. Do I just need to have the machine serviced, or am I doing something wrong?

Toyota overlocker sl3000 ; 3rd thread keeps snapping. How do I stop this ?


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!

Overlocker is not sewing. How can I thread the lower looper without it breaking?


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.

How can I set the right tension on an overlocker globe lock m-34?


The right tension on an overlocker will vary depending on the result that you want. The standard tension for just a plain 4-thread overlock stitch would generally have all the thread tensions set at the halfway mark between the high and lower number. From that point, you may need to tighten or loosen each thread tension to get all the threads to stitch evenly.

Probably the best advice would be consult your owner's manual. It should have instructions on adjusting the tensions and what to look for.

Another suggestion would be to search YouTube for a video that shows how to adjust overlocker tension.

How do I thread my overlocker


If thread is breaking, it usually means it is threaded incorrectly--either you have missed a thread guide or have it looped somewhere it shouldn't be. The tension could also be too tight on that one thread.

RAISE the presser foot BEFORE threading!

Be sure you are threading each thread in the ORDER described in the owner's manual. Most machines are threaded in this order: 2nd thread from the right (upper looper), last thread on right (lower looper (this thread must cross over the top of the upper looper in the final step!!!), then the needles--but you must check your machine's manual for the correct order!

Confirm with your owner's manual that you are threading all the guides. If you miss one of the thread guides, your machine will most likely not operate.

Also, if you break a thread, it is strongly recommended that you remove ALL the threads and start over from the beginning. Sergers can be very finicky!

This video may help, although your machine may thread differently:

Threading an overlocker


Many things can cause the thread to break on a serger. Timing, position of the thread guides, poor thread, and improper tension. One common error is the failure to thread it in the proper order. If the needle are threaded before the lower looper they will cut your looper thread.
