    Thank you. I've tried all the recommendations above from replacing needles to rethreading. I have tested the tension and it seems it's working OK. Tried using air spray to clean out any debrie. It seems it's totally missing the looper. I can see the looper arm moves from front to back around the needle as it goes down. Hmmm. Will keep playing. No luck with fixing it yet.

SOURCE: I have a white superlock 228 jaguar serger problems with right needle

Couple of things I could think of: tension disks need cleaning, there is a site that tells how to clean them, maybe 2 as I recall. Other thing is it is a much older serger, (I have one I am slowly working on to bring up to working level), so it could be that a tension spring internally has lost its tension. It might need a trip to the repair man if that is the case. Another thing is are you using correct needles for the machine? Have you changed them recently? Even new needles can be bad, so if you have to change three times to triple check it can be worth it.

I am trying to teach myself to sew.... what is a serge stitch an how do I set my brother sewing machine to do it?


A serger (overlocker) is not a sewing machine. If you look at the inside seams of a purchased t-shirt, you will usually find a serge stitch that was created using a serger (overlocker). A serger/overlocker usually uses 3 or 4 threads to create that stitch. It also trims the fabric at the same time it finishes the fabric edge. The serge stitch is a chain stitch that, if you pull a particular thread, the entire stitch will come undone.

Your sewing machine is not able to create that same stitch. Your sewing machine may have what is called an "overlock" stitch, but it will use only 2 threads (the top and bobbin) to create that stitch. You would have to consult your owner's manual to see if it can make an overlock stitch.

Setting the tension on bernette 203 overlocker


The standard tension setting for an overlock stitch is the midway point on the dials. This is the factory setting, however, it may be different on each machine due to use and age. Of course, those tension settings will need to change in order to achieve other stitches, ie rolled hem...

HINT: When threading, ALWAYS RAISE the presser foot and give each thread an extra little tug when going through the tension disk to make sure the thread is seated securely. AND, be sure to always thread each thread in the order specified in the manual.

You might want to download the Serger Workbooks (below) and work through them. As you do each project, note what settings your machine requires in order to perform each stitch satisfactorily--this will save you a lot of time whenever you want to get a specific stitch.

How do I set my Bernette 334D to overlock thin T-shirt material?


Thin, light-weight fabrics present some issues with sergers, ie the fabric tunnels with the stitching. Usually, it is better to use a narrow seam. Also, a stabilizer (wash-away) or even adding a strip of thin paper (toilet tissue, adding machine tape, etc) to the seam will help the fabric hold its shape when stitching. I have also sprayed & ironed heavy starch on thin fabrics to help stabilize.

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.

My serger doesnt make any stitches at all. I have been going through this book for 3 years and I cant get it to work


Has it ever chained off since you bought it? If you purchased it second hand it is possible that the timing of the loopers is out and this will prevent a chain from forming.

However, I'll go through general overlocker/serger troubleshooting for threading up. The critical things are to thread it exactly as the diagram shows, some sergers have a diagram inside the front looper cover so its easy to refer to when you are working on the machine. Or use the manual diagram. There is a sequence you need to follow in threading up, usually upper looper, lower looper, then the needles. This is important. Then you pull all four threads under the raised pressure foot, lower the pressure foot, and start to stitch and hopefully a chain forms. If you need to change a thread you can knot on a new colour, turn the tension to zero, then pull through the new thread. Pull the knot right through the looper eyes but you will need to cut the knot out and thread the needles with the new colour once you get there. Then turn tension back to the normal setting (5 usually) and again pull all threads under the foot.

The timing of the two loopers to the needles is critical to a stitch forming though so if you have tried everything and aren't getting a result; then perhaps its time to take it to a service centre, get it checked out and if it works fine for them, ask for a quick demo of threading up, then do it yourself with the demonstrator watching.

Overlockers are very different to sewing machines and there is a learning curve but once mastered, they are so quick and give a great finish.

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: http://www.sewingpartsonline.com/instruction-manual-elna-pro5dc.aspx
or this website has a copy for $USD10.
http://www.sewusa.com/Sewing_Machine_Manuals/Elna_Manuals/Pro_4DC_DE_Instruction_Manual.htm

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 http://sewing.about.com/od/sergersoverlock/ss/serger.htm which may help you too.

I need to switch to rolled hemming and can't find my manual


Is this on a serger?

Rolled hemming on a serger is usually achieved by doing the following: thread up for three thread overlock using right hand needle. Move blade to the right to trim fabric wider (so it rolls inside the seam). Put woolly overlock thread through top looper (this gives a smooth finish to the rolled hem). Loosen off top looper and tighten up bottom looper so the bottom looper is up tight against the needle thread on the underside. Test serge to get the stitch right, then turn the stitch length down to 0.5 to close it up tight (this uses loads of thread so I usually get everything else right first, then make this final adjustment). On my Bernette 334D tensions are R-Needle - 5, Top looper 7-8 and bottom looper is 3-4. Stitch length 0.5, differential zero.

And usually you flick a small lever or change a little finger on the foot or plate where the stitch forms, there is some variation here between models. Early Elna L4 and L5 locks you had a little finger you changed with a screwdriver on the pressure foot. Bernette has a little slide mechanicism near the blade that you flick forward to engage.

Hope this is of assistance to you - I went for a 2 hour lesson on my serger when I bought it and then came home and repeated all the techniques shown and then made notes and stapled all the stitch samples into a notebook so I could remember how I did it.

Also there are some great books on Serging, Nancy Zieman is one name that springs to mind. Or try You-Tube, she has some videos up there too showing different techniques.

I have a bernette 134 d overlocker and need the settings to work with it can you help me please


If you don't have a manual to check this, contact Ron at
a1sewingmachine.com. The settings on your dials should be
all set on 4. This number should be highlighted or marked different from the other ones. Look for the little notch (or arrow) on the machine and line that up with the 4. Make sure the threads are under the tension discs which are under the dials. When threading pretend you're flossing and pull the thread back and forth so you can feel the slight tension on the thread. Make sure your presser foot is up when you thread the machine. Your stitch length should be about 3 and the stitch width 5 and the differential on 1. These are basic settings for all sergers and you might have to play with them to get a good stitch. Feel free to ask if you have any more questions.

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.
