Re: Bernina Serger

Well, there are a couple of things you might want to take into consideration.

  1. Install new needles
  2. What is the condition of the thread
  3. If something like "5 for a dollar", throw it away and purchase a good quality thread.
  4. Get you user manual out and make sure you have threaded correctly.
And then last, but certainly not least. Pray a little!

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.

When we thread the serger . the thread is still skipping

Are you using the corfect serger system needles in it? Most domestic sergers will take the regular domestic needle 130/705X but work best with a serger needle with has a groove down the front as well as the regular back scarf. This helps with the thread pickup from the looper by the needles. Sergers also run much faster than domestic sewing machines so the tolerances are very fine.

My Bernina came with ELX705 needles and it does run better with these in it. Also you need to use mid size needles, don't go too small, probably a size 80 or 90 is best.

Check out this page for some good info as the different serger manufacturers do have their own recommended needle sometimes.

Always refer to your manual (or ring the manufacturer if lost) to double check what needle they recommend be used in your serger, it does make a difference.

How to i thread my 008d bernina serger?

I believe it is color coded right?
start with the Upper looper follow from the upper looper throught the loops below the machine up through the tension disk and to the place where the thread cone sits. now retrace your steps from the thread to the looper place thread under foot.
by starting from the finishing point to the starting point you know where you are going with the thread when you thread the machine so upper looper lower looper right needle left needle. you must get it exactly correct or it wont work

Bernina 2500DCET serger keeps breaking the centre needle thread for no apparent reason .Already had machine serviced,new needle plate didn't solve anything either. Any ideas

I have found with any serger I have used that you have to cut the looper (bottom) threads before re threading the needle threads. You then rethread the loopers.
If you don't do this, the needle threads keep breaking. Hope this helps.

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.
