Loosen the upper tension looper thread by turning the dial to a lower number. The upper tension looper is to tight and pulling the lower looper thread up. Also might want to loosen or tighten the left or right needle tensions depending on the results you get. It will be a trial and error exercise to get the correct adjustment between the loopers and needle thread tensions. Otherwise, you might want to take it to an authorized husqvarna viking dealer for service. You can locate a dealer near you by visiting the husqvarna viking website and clicking on the Dealer link on the left-hand side of the page - http://www.husqvarnaviking.com

Good luck.

I have a white speed lock 234 serger and cannot get it to chain off. The thread bunches together


Yes, thread the upper looper first, the lower looper next.

***Make sure that you have the presser foot RAISED during the ENTIRE threading process until you get to the point of threading the needles.

The second to last step in the lower looper process is to make sure lower looper thread DRAPES over the top of the upper looper & thread, then both thread tails get pulled under the presser foot and toward the back of the machine.

Give each thread a little extra tug as it goes through the tension disk to make sure it is seated. Verify that all the threading steps have been followed. Any skipped steps, extra thread wraps, or incorrect threading will most likely cause a problem.

Make sure you have brand new needles before threading. If one is bent or damaged, you will probably have issues with skipped stitches.

Set all the tensions to the midway point (the factory standard for regular chain stitch). The tensions can then be tweaked when the machine is correctly creating a chain.

If the machine messes up, breaks a thread, comes unthreaded, etc., save yourself some time and frustration and RETHREAD everything from the beginning. Trying to rethread out of order usually fails!!!

Once you are more comfortable with your machine, you can try fishing a thread, but even experienced serger users still have trouble with this.

One of the threads tears?the second one from the right.


Assuming this is a serger. The second thread from the right would be the lower looper. Nine times out of ten, when the looper thread breaks, it's because it is threaded incorrectly or the tension is set too high.

It is generally recommended that when a thread (especially a looper thread) breaks on a serger, you should remove all the threads and start over from the beginning (yep, that sounds painful but it is better to just bite the bullet and just do it rather than fighting it and never getting it threaded right). Make sure the presser foot is raised throughout the threading process, give each thread an extra tug when going through the tension disk to insure it is seated in the disk properly, follow the threading order (usually upper looper first, then lower looper) and the thread pathway is correct for each thread (no guides are skipped and thread is not wrapped around something). The last step of the lower looper threading is to make sure the lower looper thread drapes over the upper looper before being pulled under the presser foot and toward the back of the machine.

Set the tensions to the midway point between high & low numbers before testing.

Why won't my sl370 work?


Hello Mary.
By the question, it looks like the lower looper is making loops? If so, check that you are using the correct needles for your serger and that the needle or needles is/are inserted correctly:
- needles must be all the way up into the needle shaft
- needles must face with the flat side to the back and the groove to the front
- use at least needle size 12/80, not smaller

Check these few items, if the loops are still not forming:
- re-thread the serger from the start, keeping in mind to thread in the proper sequence (upper looper, lower looper, needles)
- make sure that the lower looper thread lays on top of the upper looper thread and is passed to the back of the serger and then under the presser foot when threading
- make sure that the thread are securely engaged IN the tension assembly
- make sure that the serger is set for 3-thread or 4-thread overlock (i.e. that the upper looper converter is not engaged)
- check all tension setting
- stitch length should be around 2.5 - 3.5

Let me know how it goes.
Happy serging!

How do I set up my babylock serger for a rolled hem? What is the tension to be set at?


I don't know your babylock well, some of these have automatic tensions and electronic stitch selection. But a rolled hem is achieved on any overlocker in the following way; the actual dials and knobs might vary a bit.

Firstly there is a stitch finger that you need to change or retract so that the thread can roll the fabric rather than staying flat. For a normal seam this finger sticks out in the area where the loopers and needle form the stitch holding the cut edge flat until the seam is made over it. But for rolled hems you want to retract this finger so it does roll.

On the Bernettes this is a little lever in front of the stitching area that you pull back to retract the finger. Have a look around where the stitch forms and you should see the finger. Some machines, its a part you change on the needle plate with a screw driver, or just move a switch or lever.

You want the right hand needle in place, remove the left hand needle.

Thread upper looper with wooly overlock thread, this is a fluffy nylon that pulls flat under tension but relaxes and "fills" out once its stitched into place. Gives that lovely covered look you see on shop bought tablecloth edges. Your regular thread in needle and lower looper. Usually cutting blade to the right side as you want it to cut more fabric than in the seam so it rolls under. Now loosen off the tension on the top looper, (I use 2 on mine but this is something you need to finesse with each machine), and tighten up the tension on lower looper, (about 7). Leave needle tension alone.

Now test stitch on your fabric, and finess the upper and lower looper tensions until you get the lower looper thread almost not showing, it should be right up against the needle on the underside with the upper looper thread completely wrapping around top and bottom, pulling the fabric under.a seam like this.

Test stitch and adjust upper and lower looper until this is happening.

Now, turn stitch length down to close up the stitching, probably 1 or 0.8 if you want a real satin stitch look to the hem.

Because of the stitch density this uses thread so do the finessing first, then turn the length down.

That's it! Now right down the tension settings you used and keep handy for next time.

I want to use the 2 thread rolled edge. I put the 2 thread converter on the upper looper. When I thread the lower looper, where does the thread go - ie does it go over the 2 thread converter on the upper...


Thread the lower looper like normal, and you needle. When the upper looper comes up it will push up the lower thread and then you can put it under the pressure foot torward the back and start to serge.

I have a bernina overlocker and whenever I use it the lower looper (marked in red) thread breaks. How can I fix this? It was serviced yesterday and when other people used it before me it worked fine!


Then it's one of two things. First try setting your lower looper tension on 3 and see if that works. If not set it back on 4 and cut ALL your threads and re-thread the machine STARTING with the UPPER looper, then the lower looper, then the right needle, last the left needle if you're sewing a 4 thread overlock stitch. Make sure the threads aren't twisted in the thread guide. Make sure the lower looper thread is OVER the elbow on the upper looper and over the upper looper thread. Let me know if this works. We'll work until we get it fixed!

JUKI MO 134 SERGER


How to Thread Juki MO-134 Serger from watching lady at Lyles. Turn upper blade up. Push in first then turn up.It makes threading easier. Blue Thread upper looper first. Pull thread through tension knob. Don'tjust lay it there. (She thought that is what I must have done) Orange Thread lower looper next. Pull thread through tension knob as inthreading upper looper. Adjust lower looper so it is right nextto upper looper so that their points are almost together and directly belowsewing needles. Lower looper will be in front of upper looper (I believe). With tread from upper looper pulledback, slightly lift lower looper above upper looper and thread. I think this isright. Pull thread back with other thread. Tension is the key. Remember that. Yellow: Thread left needle first.Remember tension. Pull thread through curled wire on left side of needle arm. Green: Thread right needle. Rememberabout tension. Pull thread through curled wire on right side of needle arm. b> Note: Before sewing turn the wheel tomake sure the stitches are going together correctly.

Rolled hem or rolled edge


You need to disengage the cutting blade by openingfirstly opening the front and left hand side covers. pull on the larger of the two silver knobs and slide the red lever towards you. I'm not sure what the tension settings are, but I'm certain you need to reduce them a fair bit to aid in the rolling effect. I only use 3 threads when doing a rolled hem.
My description isn't too detailed but I hope it helps!

Singer overlocker


Most likely is the left looper thread is trapping the needle threads.

Remove the threads and start over in this sequence....

Left looper - right looper - left needle - right needle.

If you thread the needles before the lower looper, the needle thread wrapped over the looper will be under the looper thread and will never be free to form a stitch, so the threading sequence is critical.
