SOURCE: Thread breaking

have you tried to use a different type of needle such as a metallic ? this type of needle has a larger eye than regular and helps to keep some of my embroidery threads from breaking. also can you sloe the speed of the machine down? i sometimes found this helped me in embroidering. hope this helps.

SOURCE: Tension

I answered this a couple days ago but don't know if it went through. I can sew through 6 or more layers of denim with my 226, no problems at all. In my 30 years in the upholstery business I never had a problem sewing leather, vinyl, canvas or multi-layers of fabric. The 226 Consew, the 111W and 211w Singers I had presented zero problems with heavy fabrics - and I don't consider vinyl "heavy".

You need to first of all check threading. If the machine's threaded wrong you're break thread. Also you need to oil under the bobbin case and the bobbin hook and the rest of the parts as well.
Then, loosen thread tension on top by turning the knurled knob that's on the spring that's holding the tension discs. Also loosen bottom tension on the bobbin case by turning the small, left-most screw on the outside of the bobbin case counter-clockwise. Do both with the presser foot down. Pull the thread(s) out and feel the tension. You should be able to pull the threads out with some little effort. Tighten both a little at a time until you get some tension. Run a couple seams and check where the threads meet in the fabric. They should meet in the center. Also check stitch length. If you're using 92 thread (is should be left twist), you should run the machine at about 6 - 7 stitches/inch. I'm running my machine at 5 - 5 1/2 with #69 nylon bonded, and 6 - 6 1/2 with #11 mono.
One more thing; if tension's too loose at the bobbin or top, the machine will jam in the bobbin and thread will break.
Go to www.consew.com and download a pdf owner's manual for free. You need to click on the 224. That machine, the 225 and 226 are the same.

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.

Model 3434D. Why does lower looper thread keep breaking?


Usually thread breakage is due to incorrect threading or tension set too tight. When thread breaks, the Best Course of Action is to clip all the threads between the thread tree and the tension disks, Raise the presser foot, and pull all the threads down and out. (Never pull threads up through the tension disks.)

RAISE the presser foot, rethread each and every thread in the order specified in the manual and confirm that each thread path is correct. Grasp each thread between the thread tree and the tension disk with one hand and with the other hand grasp the thread below the tension disk and give a little tug to make sure each is seated firmly in the tension disk. Also on most machines, the lower looper thread must drape over the the upper looper before being pulled under the presser foot.

Lower the presser foot and set each tension guide to the midway point (the factory standard) and retest.

Usually, rethreading only the broken thread will fail. (For some reason, sergers are very finicky.) Just bite the bullet and rethread each and every thread.

I need a diagram of how to thread it or a problem solver the thread eeps breaking at the needle


Search the internet for:
Manufacturer + Model + the word "Manual"

or search YouTube videos for "sewing machine threading." You may not find your exact machine, but many machines have similar threading patterns. Be sure to raise the presser foot before threading the upper thread so it will seat properly in the tension disk.

If the thread is breaking at the needle, it could be several problems:
Threaded incorrectly--#1 cause
Upper tension too tight
Install a brand new needle compatible with the fabric & thread
Make sure the thread is not too large for the needle eye
Avoid old, fuzzy, bargain bin thread

The thread keep bursting as soon as i start to sew although machine is thread properly


Check your thread tension isn't too tight, try on a piece of similar fabric that you are going to use, try sewing a line of stitches, if the thread snaps, change your tension number, then sew another line with your different tension number, try this until you can stitch without the thread snapping, it could be that your bobbin tension is too tight. Can you check your machine manual, it could even be the needle or the thread that's wrong for your fabric. But I would say, check your tension.
Hope this helps.

Trying to thread and thread keeps breaking when i try to use i, i am following the guide but cant figure out what i am doing wrong


Hi. Make sure you're not using old thread. Old thread, or thread that has been exposed to sunlight, gets weaker and is more likely to break. When I realized old thread was causing problems, it about broke my heart to throw it all out (I had spools of thread that my momma used.....wooden spools...but out it all went.)
Another thing that could cause your thread to break is if the top tension is too tight. You might try loosening it a bit and see if that helps.
Let me know if this helps, ok?
Happy Sewing!
Robbie
