I have a YAMATA fy14u4ad, but I don't have the book to tell me the thread setting so what should the thread setting be for all 4 threads


Assuming this is a 4-thread serger. The thread tension setting will depend on which stitch you are making. A standard 4-thread overlock stitch would generally have the tensions set in the middle. FWIW, the tension in this setting is correct when the threads meet in the middle of the fabric. It should neither be off the edge of the fabric or so tight as to create a puckered edge.

How do I get a balanced tension with my Elna 624 overlocker?


The best way is to thread with 4 separate colors of thread and then studying the stitch result. With the 4 colors, you can easily tell which thread tension is "off" and whether it should be tightened or loosened. However, a serger is not like a sewing machine where you can set the tension and use that setting for most projects. With a serger, a change in one or a couple of thread tensions will create a totally different stitch.

For most machines, there is a mark at the midway point on each tension control that is the "optimal" tension for a 4-thread overlock. HOWEVER, every machine differs, so these settings may need to be tweaked.

Help plse, after threading it dont make the overlocking stitches. New machine, help with right way to thread machine and the smaller detail of threading.


Your machine is either not threaded correctly, or the individual threads have not been threaded in order. Be sure to ALWAYS RAISE the presser foot when threading the machine. You must follow the instructions exactly or the machine will most likely never work properly. Can you at least get a training class on your machine? A class is indispensable, especially when it comes to using a serger.

Even if it is not the same model, these instructions may be helpful.

I cant feed the overlocker.. so it dont want to work


Best to refer to the owner's manual. You can search the internet for the Make + Model + the word "Manual" and you may find a free download.

ALWAYS raise the presser foot while threading the machine.

Be sure to thread each in the order specified in the manual (usually, Upper Looper, Lower Looper, then the needles). Threading in the incorrect order will guarantee failure!

If a thread breaks or the machine messes up, it's usually best to remove All the threads and rethread from the beginning.

To start out, it helps to use a combination of different color threads.

Set the tensions to the midway point (the standard for basic overlocking).

How can I set the right tension on an overlocker globe lock m-34?


The right tension on an overlocker will vary depending on the result that you want. The standard tension for just a plain 4-thread overlock stitch would generally have all the thread tensions set at the halfway mark between the high and lower number. From that point, you may need to tighten or loosen each thread tension to get all the threads to stitch evenly.

Probably the best advice would be consult your owner's manual. It should have instructions on adjusting the tensions and what to look for.

Another suggestion would be to search YouTube for a video that shows how to adjust overlocker tension.

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.

Sewing machine stopped making the stich


Unthread the needles, rethread the loopers properly, then rethread the needles. Make sure that all four threads are pulled securely into the tensions and retry.

The loopers must always be threaded before the needles or it will not chain.

Problem with Homemaker overlocker


first thing to do is lodge a complaint
and send all emails via ebay so it is recorded,
if you paid via pay pal you may have some kind of guarantee. over lockers can be very sensitive and may require some thing as simple as adjustment or lubrication or at worst a service.
threads breaking are caused buy poor thread quality or over tension,or wrongly threaded.
Over tension can be caused by the the tension guides being rusty or stuck. pull the thread through the tension guides to see if it is moving with some minor friction. hope this helps
