They are always difficult to thread. Keep perservering. You will get the hang. Is there a diagram inside the machine itself? If all else fails, take it to a dealer and ask them to show you. Have you asked your friends? Then when you have it threaded, next time you want to change colours, cut the thread off BEFORE you unthread the machine. And tie the new colour on to them. Then run the machine. The new cotton will pass through the machine and you should only have to thread the needle again. This saves you having to thread it each time. good luck.

Threading the 634d took me over 8 hours to get the thread to go though the right needle. Is there an easier way?


Most new serger users have trouble threading the loopers. Something that helps me thread needles (sewing machine, serger, or hand needles) is to lick your index finger. Then swipe it across the back of the needle eye. The moisture helps draw the thread through the eye.

It helps to have the needle at the top of its cycle when threading, Removing the presser foot while threading the needle will sometimes help reduce the interference.. Be sure that your thread is not too big for the needle.

Don't feel bad. It took me 8 hours to thread my first serger, but my problem was getting the loopers threaded. Practice does make it easier...

The serger will not form the initial chain. Have checked threading and have new needles, any ideas?


It's an odd thing but on my serger, it actually matters the order in which I thread it. I *try* to tie the new thread to the old and pull it through rather than re-threading, but when I've had to re-thread, I've had trouble getting it to loop again when I thread left to right. It seems that the loopers only loop if the right looper is threaded before the left.

Serger is not stitching


... not quite sure what you mean by "not stitching", here are a few things to check. If the problem is more specific, please leave me a note with more details.
Let's start right from the beginning (for 4-thread overlock/serge):
1. According to the serger manual, ensure that the proper needles are being used. That they are inserted all the way up into their positions and that the flat side of the needle is facing away from you. The left needle will appear to be shorter that the right, that is OK, all is going perfectly.
2. Use four good quality spool of serger thread (good quality sewing thread is fine also) and place them on the spool or cone holders. There should be "little bucket looking things" that fit onto the cone pins to make the cones sit nice and straight, use them. Rattling thread will cause grief.
3. The first thread to be loaded onto the serger is the Upper Looper ...it is the big needle looking thing that swings left to right and back again above the sewing surface. Follow all the threading guided according to your manual, the threading guides are generally coded in a colour specific for this looper. Once the eye of the Upper Looper is threaded, place the thread under the presser foot and to the left. Presser foot down.
4. Next is the Lower Looper, the big needle looking thing that swings left to right and back again under the sewing surface. It can be a bit tricky in some sergers as the thread need to pass to the left and then back to the right under the sewing surface. Your manual should have a good diagram if you can not follow the threading guides on the serger itself. Again the threading guides are generally colour coded with a different colour but specific for the Lower Looper. Once the looper is threaded, it is important that the thread is placed directly OVER the Upper Looper as it comes out of the eye of the Lower Looper. Place the thread now under the presser foot and to the left. Presser foot down.
5. Thread the right needle front to back and place the thread under the presser foot and to the left. Presser foot down.
6 Thread the left needle front to back and place the thread under the presser foot and to the left. Presser foot down.
7. Hold the four thread ends firmly in the left hand and give each thread individually a good pull down over the serger and behind, this will ensure that the threads are all engaged in the tension dials.
8. Set the tensions to the middle number, although this may vary with the brand and model of your serger. If you have the manual check for the correct settings specific to your unit.
9. Set differential to 'normal', or '0' (if your unit has one)
10. Set stitch length to about 2 1/2 to 3.
11. Make sure that the blade is in cutting position. We can trouble shoot blade position later if needed.
12. Make sure that you have the overlocking plate installed ... not the rolled hem plate (if your serger has two plates). Some sergers use the same plate for both functions.
13. Using two layers of medium weight fabric do a test stitch, what is the result? Is a chain forming? Are there stitches on the fabric? Are they looking the way they should?
Hopefully this has helped you, please let me know.
Cheers.

Never heard of such a problem with this brand. Are you threading in the correct order? Are you threading with the tension off, either by turning the tensions to 0 or by raising the presser foot (I don't know which you need to do in this model) ? Are you using the correct needles, and are they fully seated right way around? Can you provide photos of the serging it's doing now?

For what it's worth, I drive a couple of Jukis -- this is the threading pattern for a 3/4 overlock with one of 'em: http://picturetrail.com/sfx/album/view/24103653 http://picturetrail.com/sfx/album/view/24104540 http://picturetrail.com/sfx/album/view/24104556 http://picturetrail.com/sfx/album/view/24104568 and photos of stitch formation: http://picturetrail.com/sfx/album/view/24107012 http://picturetrail.com/sfx/album/view/24107038

My first bit of advice is to join a general sergers group on the internet, like the yahoo group "sergers":
https://groups.yahoo.com/neo/groups/Sergers/info I think the second bit of advice would be to consider finding a different serger mechanic and/or teacher.

Cant thread correctly


Do you have a manual?
You can get a free manual to download for a Toyota Serger here:
http://www.aisin.fr/catalog/download//manuel%20SL1,%20SL1T,%20SL1T-X,%20SL1A.pdf
They also have a threading guide, in colour, but it's written in French.
http://www.aisin.fr/catalog/download//SLEnfilage.pdf
Although the manual is for another model number, it should be useful as most sergers thread in exactly the same way.
Hope this helps!

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 need a manuel for an Elna 411 serger


I could not find a manual for this model, but did find a fairly universal guide at Singer - http://www.singerco.com/pdf/14SH654_threading.pdf

A very good book for sergers from threading to maintenance is Nancy Zieman's Serge With Confidence.

Raise the antenna to it's highest position.

Raise the presser foot and set the tensions (if not auto tension) to zero.

Thread in the order indicated in the download or on the front of the serger/inside serger door.

I bendt my needles, and after changing them it wont sew. the threads just come out without getting sewn together.. just 4 straight threads..


Once the thread breaks, the serger usually has to be re-threaded - all four components of the serger.

Raise the antenna to it's highest position.

Open the tensions to zero.

Turn the handwheel so the the loopers are at their highest position. Some sergers have a mark on the handwheel that aligns with a mark on the side of the serger for this step.

Thread according the the sequence indicated on the threading guide - this is either on the inside of the door or on the serger.

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.
