Sounds as though you may have a burr or rough spot on the hook where the bobbin inserts. Run your finger along the edge of the hook to see if there are any rough spots.I'm sure you're going to find at least one from the time you broke the needle.Once you locate it, remove it with an emery stick or small sharpening stone. Polish it so that it is smooth. Should work okay.

I think you might have better luck if you use 40 or 50 weight thread.

Make sure the feed dogs are dropped (or feed dog cover is on - I can't remember which way this machine works). The stitch length on the machine has no function so ignore it. (I set it to zero so the machine doesn't have to work as hard). Hopefully this is all that's wrong. If not, use a shorter setting for the stitch length on the regulator, oil the hook and move slowly and smoothly.
Good luck!

Loops on the bottom of the fabric direct the problem to the top thread. Rethread again and make sure the thread goes through the tension discs. Lift the foot, because this is what opens the discs. When sewing and the foot is down, the discs should be closed and thus giving the upper thread the tension it needs.

Are you threading it correctly? I've had this problem twice, the first few times the thread was wrapped around different items (below the spool holder and then around the needle) the other times I threaded it wrong. Double check that the machine is threaded correctly with the manual. I've missed a step here or there and it does make a difference.

Difficulty to do needle threading on S4D overlocker

Sergers are absolute "bears" when threading compared to sewing machines. If/when you get frustrated, walk away. It took me the majority of one day before successfully getting my first serger threaded properly. Using four different color threads is also helpful when learning the serger--especially when it comes to adjusting the tension.

It is very important to pay attention to the order the threads are threaded, as well as making sure the thread path for each is correct. (Consult your owner's manual as different brands will look different.) Most machines require that the upper looper be threaded BEFORE the lower looper because the lower looper thread will cross OVER the upper looper thread as the final step before going under the presser foot.

ALWAYS RAISE the presser foot when threading!!! This releases the tension disks.

Also, when threading through the tension disk, be sure to give the thread an extra little tug to make sure the thread seats firmly in the tension disk. (Grasp the thread just below the thread stand with one hand and then grasp the thread below the tension disk with the other hand and give a little tug--sometimes it will make a little popping noise when it seats.)

Start out with the tensions set at the midway point. From that point, you can test your machine to make sure it is serging properly. Then you can adjust the tensions to suit you or the project you are making.

If the either looper thread breaks or pulls out, remove BOTH looper threads and rethread from the beginning!!! Trying to finagle threading of only one thread will most often result in a machine that will not operate correctly. Just bite the bullet and rethread both threads (in the order specified in the manual).

I seem to have trouble using the tweezers to thread the looper eyes, so I use dental floss threaders instead.

One more hint: NEVER pull the thread out of the machine by pulling it UP through the machine. This could damage or wear the tension disks. Always clip the threads just below the thread stand, RAISE the presser foot, and then pull the clipped threads DOWN through the looper eyes and needles.

Be sure to clean and oil your serger frequently. This is very important to get the best performance from your machine. Use only fresh oil recommended by the manufacturer and apply only a couple drops each spot.

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.

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!

How to Thread Serger Overlock Machine

1 Answer

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.

Adjusting tension on overlocker

overlockers and sergers are annoying in that every time you change materials and threads they must be re-tensioned.

Get a scrap piece of material. Thread your machine correctly according to the instructions in your manual. If no manual most sergers are threaded, upper looper, lower looper then needles from right to left. Make sure you thread with the presser foot UP.

You want to balance the stitches Begin by adjusting the looper dials, you want them to meet right at the cut edge. Then adjust your needles. Keep doing test seams until you have them balanced. If you are a novice... try threading with each thread point having it's own color. That will help you identify which thread is giving you fits.

Have fun.

Correct threading for 4 th. Juki ind. overlocker

Overlockers and or Sergers are ALWAYS threaded the same way. Upper looper, Lower looper, right needle, left needle. If you have a model number for your Juki we might be able to find you more information.

The best way to figure out tension problems is to thread each thread in a different color so you can determine which thread is giving you problems.

These machines can be frustrating and EVERY time the thread breaks you MUST start the threading problem from the beginning... upper looper, lower looper, right needle left needle.

I'm not sure how to thread my machine, I lost my manual elna lock pro 5Dc

I would suggest that you buy a new manual for this as your overlocker has 5 threads that need to be threaded up correctly to form a stitch and there are several different stitches that can be made with this model such as a rolled hem, chain stitch, three thread overlock, four thread overlock and safety stitch with three thread overlock, lots to learn.

You can buy a manual here for $USD14.99:
or this website has a copy for $USD10.

Always well worth buying the manual and saving a lot of frustration trying to guess how things work and it adds value if you are going to sell the item.

You can get some general overlocker threading tips from which may help you too.

Do you have a manual, project book or anytrhing that gives information on how to use the features of the 936 surger?

I would suggest that you contact Husqvarna Viking to purchase a manual for your 936 serger, their contact details are here.

You could also get lots of general sewing info from Debbie Cosgrove at is a fantastic source of information on sewing techniques, sewing machines, sergers and projects too.

Sergers are quite differernt to a sewing machine and there are plenty purchased, used once or twice, then put away or sold because they are a bit difficult. But like any new skill learnt, taking a class and learning hands on is so much better than trying to figure out from a manual so if you can find a local Husky dealership, I'd enquire about an "intro to serger" type class, well worth the money and time.

Yours will probably do a three thread overlock, 4 thread overlock and rolled hem stitch, these three seams will cover a variety of sewing tasks and applications. You can seam knits and lycra with the 4 thread, and neaten the raw edges of just about all fabrics with a three thread. The rolled hem allows you to do a small covered edge which covers the fabric cut edge wrapping the thread around it closely. Beautiful on very light weight fabric edges like ruffles and frills where you have yards of fabric to neaten, much quicker than turning edge twice and straight stitching it.

There are other techniques with a serger such as sewing stretched elastic onto fabric, sewing over nylon fishing line to give a fluted edge or stitching over a string of beads. These are best done with a special foot for this purpose, elasticator or beading foot. You can also use decorative threads through the loopers to give an attractive finish.

There are several good sewing with a serger books on the market, Singer does one but there are other great ones too. You could always borrow one from the library before committing to buying it.

Sould i use overlock thead on my brother embroidery/sewing maching

It is, of course, possible to use overlock thread in a typical machine. Generally speaking, you only want to use overlock thread to overlock ("serge"). The reason for this if that while typical all-purpose or sewing machine thread has 3 strings wound together, overlock thread has only 2. When you are using 3, 4, or even 8 threads at a time with a serger, each strand doesn't necessarily have to be as strong as when you are sewing on a machine with only 2 threads. So, you physically could use the thread, yes, but it will not be near as strong, and you will probably have issues with breakage while sewing as well. The cost savings you think you may be saving by using overlock thread (which is, after all, considerably cheaper per yard), well soon be overrun with extra time sewing due to broken threads and overall less quality in your garment as it will be made weaker.

Trouble with my Huskylock 680D overlocker Tensions

You need to re-thread the serger.

Refer to the manual or open the front of the serger to see if the threading diagram is there.

With most sergers, you begin with raising the presser foot, then set the tensions to zero.

Begin the threading with the upper looper (curved looper), then the lower looper and the needles last.

Pull the thread under the presser foot and to the left side of the serger.

Set the tensions back to normal 4 - 5 usually.

Lower the presser foot and hold onto the threas tails as you stitch a chain. If the chain of the four threads is ok, you are ready to serge fabric.
