SOURCE: 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.

SOURCE: BabyLock Proline upper looper thread keeps breaking

I ended up switching the spools of thread around. Apparently, even though I had purchased good quality threads, one of the spools was wound in a way that made the thread loop and twist around. So I put the offending spool of thread through one of the needles and put the needle thread on the upper looper. That seems to be working. By the way, BabyLoc was very unhelpful dealing with this problem.  Thank you!

SOURCE: my white speedylock serger 1634 thread keeps getting in knots

i have the book and it says thread from inside out, inside looper (upper) then lower, then thread the needles, first right then left.  I have found that it does not matter if you thread the needles or loopers first but that you should try to thread from inside to out.

I will make this easy first always thread the machine upper looper then lower looper then the needles if a thread breaks especially if it was one of the loopers, make sure to pull the needle thread out before hand then rethread. as for the breakages look to see if the loopers are hitting each other when they cross and see if the needles are hitting the loopers when they go together either of these things will cause problems if so it will need to be looked at by a tech

I have a white speedy lock serger model 7340. I completely pulled all threads out and now trying to re-thread new thread. I have tried around 15 times. It will not loop. Threads don't interlock at all


Be sure that you are threading each thread in the correct order. The manual should have those instructions.

ALWAYS RAISE the presser foot when threading the machine!!!! For most machines, the upper looper is threaded first, the lower looper second (the lower looper thread finishes by draping OVER the top of the upper looper and then pulled toward the back of the machine), then thread the needles. Give each thread an extra little tug when threading the tension disk to make sure it is seated completely.

Even if you are unable to locate a tutorial for your particular machine, most models from the same era will thread the same.

Don't be surprised if it doesn't work the first, second, or even the third try. It took me most of a day to get mine threaded correctly the first time!!! Patience!

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.

White Superlock serger continually breaking needles


First take all the thread out of the machine. Put in new needles and run the machine slowly by hand and see if there is a problem with timing. If the needle hits and bends or breaks... take it in to be timed. If the needle don't hit....

Make sure you are properly threading this thing. Unlike a sewing machine which gives you some leeway, Sergers must be threaded in a certain order. Typically, upper looper, lower looper, right needle left needle. If you break a thread you can't just rethread that thread... you have to start from the beginning.

You might check singerco.com for the manual for this thing. They have most of white's manuals online they are identified by a W before the serger model number.

Left needle thread keeps breaking on my White Superlock 2000 ATS serger


the tension must be too tight or check to make sure the spool does not have a crack that is catching the thread in the middle of using the serger. When the serger is working and the spool has a crack it catching the thread then you press to go on and it gives a break the needle because the spool is still holding onto the thread

My serger will only sew a few inches, then the thread on the lower looper breaks. I have checked threading, rethreaded many times.


Been there, done that. Old serger almost went out the window more than once.

Raise the thread antenna and loopers to their highest positions.

Set the tensions to zero. If your serger has auto-tension, raise the presser foot as this also opens the tensions.

Begin threading from the right as indicated in your manual or on the door of the serger.

If this continues, the serger may need to be serviced as the timing could be the problem.

Ask before leaving the serger as the service cost usually starts around $100.

I finally gave in and bought a Babylock with instant jet-air threading.

I can't get the thread adjusted correctly on my


You did not mention the type of fabric that you are having trouble with. For instance, stretchy fabric may require a slightly different approach. I'll assume that you are using a medium weight woven material.

First of all, ensure that you are using good quality cone thread, such as Maxi-Lock and that your needle(s) are new or in good shape.

Secondly, make sure that each thread is pulled fully into its tensioner, BETWEEN the discs and not behind them or riding on top of them. Grasp the thread from both sides of the tension and pull it through like dental floss.

Test sew if one or more threads was not in the tensioner. If still not good, proceed with the next step.

If you have your instruction manual, look at the page which tells you how to set it up for normal tension. If you don't have a manual, call 1-440-808-6550 and they will send you a free PDF of the manual.

NOTE: Most White 532 tension dials rotate TWO full turns around, so you don't know if you are at 5 or 15.

Turn all of the tension dials to zero, each one should have no tension. Then set the tensions as follows:

Left needle: 7
Right needle: 3
Upper looper: 3
Lower looper: 3

Adjust slightly as needed.

You can get sewing machine manuals online at sewingmanuals.com. I didn't see the superlock 2500 but there were other superlocks. They may thread the same way.
