Joyee (Yuki copy) JY-A320 runs smoothly but doesn't stitch.

Hi. I'm so glad I found this site! I am searching for a user's manual for the Joyee JY-A320 industrial sewing machine. This machine is supposedly a copy of the Yuki. The thread keeps jumping out of the needle and doesn't stitch. Any hints would be both helpful and very much appreciated! Thanks. Colby

SOURCE: Loose stitching underneath. HOW CAN I FIX!!!!

Sounds as though you may have a burr or rough spot on the hook where the bobbin inserts. Run your finger along the edge of the hook to see if there are any rough spots.I'm sure you're going to find at least one from the time you broke the needle.Once you locate it, remove it with an emery stick or small sharpening stone. Polish it so that it is smooth. Should work okay.

SOURCE: needle thread breaks while quilting on machine frame

I think you might have better luck if you use 40 or 50 weight thread.

SOURCE: Needle Thread breaking after about 30 seconds of quilting

Make sure the feed dogs are dropped (or feed dog cover is on - I can't remember which way this machine works). The stitch length on the machine has no function so ignore it. (I set it to zero so the machine doesn't have to work as hard). Hopefully this is all that's wrong. If not, use a shorter setting for the stitch length on the regulator, oil the hook and move slowly and smoothly.
Good luck!

SOURCE: skip stitch

The three most obvious causes (other than that of the machine possibly being slightly out of time) are:

1) Too small of a needle size - increase the size.

2) A needle that has a flaw / defect - change the needle.

3) Needle not inserted correctly, either not pushed all the way up into the needle bar, or not installed facing the correct place. On this machine, the small "scarf" in the needle (an indent just above the eye) shouldface the right side of the machine.

Are you threading it correctly? I've had this problem twice, the first few times the thread was wrapped around different items (below the spool holder and then around the needle) the other times I threaded it wrong. Double check that the machine is threaded correctly with the manual. I've missed a step here or there and it does make a difference.

I have no user manual and dont know how to thread or adjust the stitching

Search the internet for:

Make + Model + the word "Manual"

If you also search the internet, including YouTube, you will most likely find web site articles and videos that describe the functions you need help performing. Search for items like "threading sewing machine," "sewing machine stitch," etc.

Bernina sewing machine

Hook don't catch thread

Possible reasons:
  • bent needle
  • needle/thread combination is not correct. When sewing, the thread should travel smoothly down the long groove on the front of the needle. (see user manual, chapter "Threads and needles")
  • stitch plate damaged
  • wrong hook timing (sewing machine needs to be taken to a BERNINA dealer for servicing)

My yuki serger run too slowly.i want to set up it speed faster because i am a worker in a sewing shop

Domestic sergers usually sew 1500 stitches per minute, you can't increase this. You can make the stitch longer which will move a bit more fabric through with each stitch but obviously you need the stitch to hold the fabric too.

If you find this is not fast enough for the volume of work you need to do, then shop around for an industrial machine. Usually built into a table, and designed to feed very fast. Try the Juki website, they do a big range of industrial machines such as these

I have a white brand sewing machine, Model # 2468, Serial # 70722. It contains 24 zig zag design great shape. The problem is I cannot find the manual. Any possibility of finding one? Thank you.

The Singer site usually has White manuals free to download.
I couldn't find a manual for the w2468 but I did find one for the w268.
Just type in w268 and click on search.
On the next page click on free download!
They also have a manual for the w2400, maybe it is similar to your machine?
Hope this helps!

I was given a Kenmore sewing machine 12 stitch model# 158-13521 and I am not sure how to change the dials to get size of stich, or width. I was looking for a manual but I cannot find one. I have found...

Whew, that was a tough one but I found you a deal. If, you go to you can download your manual for $5.95 and they take paypal, which is great. Good luck and happy sewing, I am glad that my sources remembered this site, my usual ones couldn't help.
