Always thread the lower looper first. Then the upper looper. Finish by threading the needles.
By the way, the lower looper is the one which is always below the needle plate and the upper one is the one which travels above the needle plate.

Viking Huskylock 560 ED threading diagram


Viking 560 ED Huskylock Handbook

Threading Serger this may be helpful even if it is not the same model. The sequence of threading loopers is VERY important. If you thread them out of order, be prepared to be frustrated beyond belief!!! Something else (I don't think she mentioned) is to ALWAYS RAISE the presser foot when threading your machine. This is true for sergers AND sewing machines!

Tip

Threading a Serger


When threading a serger, you MUST follow this sequence.
1. Upper looper
2. Lower looper
Then thread your needles. If your thread breaks, you must un-thread your needles before re-threading your loopers.

How do you work a huskylock 430 serger


Here's an owner's manual:
User Guide

Usually, if the machine breaks thread, it is because it is threaded incorrectly, the tension is too tight, or there could be a bad needle. Make sure you are using the correct needle and inserting it properly.

Check to make sure the thread coming from the spool is not wrapped around something that it shouldn't, ie the spool pin or the thread tree.

Unthread everything, RAISE the presser foot, then rethread from the very beginning making sure the threads seat properly in the tension disks.

Thread each thread in order as instructed (usually the upper looper first and the lower looper second with the tail draped over the top of the first looper). Pull at least 6 inches of thread tail of all three threads and lay them all in a straight line under the presser foot extending toward the back of the machine.

BE SURE to check your threading sequence against the instruction manual diagram since missing one thread guide will cause problems.

Set all the tension dials to the midway point to test your stitching. HINT: it helps to thread with 3 different colors so you can determine which threads are presenting a problem.

When a thread breaks, it is best to rethread everything from the beginning. Sergers are very finicky machines and even if you try to rethread only the broken thread, they will generally refuse to work.

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 get my Serger to sew properly?


I'm afraid you've threaded your serger incorrectly. I've done it myself more than once, so I try to make sure that I tie new thread to old and pull it through the machine rather than try to re-thread it. That avoids the problem for the future, but doesn't help you now.

Here's what you can do right now to work out the problem:
1. Get out your owner's manual and check the thread path(s) for each thread. Be sure you've got them right, especially the loopers (usually the two threads on the right-hand as you look at the machine).
2. If you don't find any obvious errors, change the sequence of the looper threads - that is, which one is threaded first. I know it doesn't sound like this will help, but it fixed mine.
3. Be sure that none of the threads are caught under the feed dogs, they should pull fairly freely toward the back of the machine.
4. Start sewing without fabric in the machine. I know this is wrong for a standard sewing machine, but you should get a 'chain' with a serger. If it's not 'chaining,' go back and try these steps again.
5. If that doesn't fix the problem, or if it chains and still won't stitch, change your needles. They should be changed now and then anyway.
6. Be sure to lubricate your machine often according to the owner's manual. Most sewing machines need more oil than they get.

Why would the lower looper thread be cutting in a new overlocker machine?


Tensions, broken finger on needle plate, burrs on the needle deflectors, threaded in the wrong sequence, low quality thread are all common reasons why the thread breaks. Threading sequence is extremely important on a serger.

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.

I NEED HELP WITH THREADING 4 NEEDLE OVERLOCKER this has to be done in a sequence to form a chain HOW DO I DO THIS


Four needles or four thread (two needles and two loopers)?


Raise the antenna to it's highest position.

Raise the presser foot.

Set the tensions at zero.

Turn the handwheel so the loopers are at their highest position. There may be a mark on the handwheel to match with a mark on the side of the serger for this step.

Thread in the sequence shown on the inside of the serger door.

Need instructions for threading Juki MO 3314


Open the font of the serger and the instructions will be printed on the serger or on the door.

Raise the presser foot and set the tensions to zero when threading.

Turn the hand wheel so the upper looper (curved one) is at it's highest point and thread it first, and then the lower looper.

With some sergers you must thread in a certain sequence. This should be indicated in the instructions on the serger.

Set the tensions back to normal ( 4 - 6), lower the presser foot and run a length of stitching to see if the threads are knitted together as they should before you start serging your project.
