I have a bernina overlocker and whenever I use it the lower looper (marked in red) thread breaks. How can I fix this? It was serviced yesterday and when other people used it before me it worked fine!

Then it's one of two things. First try setting your lower looper tension on 3 and see if that works. If not set it back on 4 and cut ALL your threads and re-thread the machine STARTING with the UPPER looper, then the lower looper, then the right needle, last the left needle if you're sewing a 4 thread overlock stitch. Make sure the threads aren't twisted in the thread guide. Make sure the lower looper thread is OVER the elbow on the upper looper and over the upper looper thread. Let me know if this works. We'll work until we get it fixed!

Be sure to thread your serger in the order specified in the manual. For Berninas, the upper (inside) looper is always threaded first. The the lower (outside) looper is threaded next. Be sure the lower looper thread tail drapes over the top of the upper looper elbow.

I need help in good tension for rolled hem in empisal 606D overlocker


Your owner's manual should have instructions for rolled hem settings. My Bernina manual has a the following settings:
Medium weight fabric
80/12 Universal needle
3 cones serger thread
Upper looper 3-5
Lower looper 7-9
Left needle (no thread)
Right needle 3-5
Stitch length 1-1.5
Cutting width 2-3
Differential feed N

Can use woolly thread in the upper looper, but the tension may need to be loosened since the woolly nylon thread will stretch.

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.

How do I thread the Bernina Overlocker


Depends on your serger model. Best idea is consult the owner's manual. Some manuals are available for download on Bernina's web site (look under Support). Be sure to thread in the order specified in the manual. Usually the upper looper is first, then the lower looper second, then the needles. (Hint: The lower looper thread ALWAYS lays over the top of the upper looper thread in the final looper threading step.)

You can also download a serger workbook too.

I can't find my Bernina Serger 800 dl manual - how do I thread for a 2 thread rolled hem, and do I need a upper looper cover and that the heck is that anyway?? Thanks


From what I have read this manual is less than desirable. Neither is the one for the brand that I have.

You may have better guidance if you purchase and use Nancy Zieman's "Serge with Confidence". I have found it very helpful.

For the two thread rolled hem, the looper cover is used to "trick" the looper into "thinking" it is threaded.

On my serger (not a Bernina), this is referred to as a "subsidiary looper". It is a spring type mechanism that fits in a small hole at the top of the upper looper.

You use a rolled edge presser foot; right or left needle; stitch length @ normal or wider; stitch length @ 1mm for the left needle/0.5 for the right needle; differential feed @ normal; needle tension - tighten; lower looper tension - normal or looser; two thread looper cover - engaged.

Test and adjust the tension as needed before making the rolled hem on your garment.

I hope this helps.

I have a 3/4 thread 234 model Bernette overlocker, which badly needs a sevice. It has always been a pest of a machine to thread and the lower looper has not worked for years, so have been using it as a 3...


Newcastle where?

In the US, a sewing machine repair service can do the work - a Bernina tech would be better.

Service starts at about $100 plus any parts that have to be replaced.

If you go to the Bernina website, there should be a dealer locator option.

How do I change to straight stitching from overlock stitch please? I am using a friends Bernina1015 and she is in New Zealand!


Hi. Take out the looper threads and just leave the needles threaded. And if you want just one line of thread unthread one of the needles.
Of course then your going to have to rethread the loopers later to overlock in which case its important to do them in order.
Upper looper, lower looper, right needle, left. If yours is color coded as most are then the order would be blue, red, green, yellow.
Hope this helped.

Threading a bernina serger


Here is a little jingle to remember as far as the order of threads to thread...
Upper looper, lower looper, left needle, right.
Usuall if you give numbers to the threads from left to right as 1,2,3,4 , you would thread it in the order of 3, 4, 2, 1 . Also when threading the loopers be sure the lower looper thread goes over the top of the upper looper thread as it goes out the back.
Hope this helps.

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.

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.
