Put new needles in it.

Following the colors, thread the upper looper first, then the lower looper. Next thread the needles. Always thread in this order.

Hi there 1st of all i like to say please change the rusti tension plates, otherwise its not moving well & the boobin does not follow the alinment. For humidity control i suggest you fix an air condition system in your working room & make the place clean & dry. Thanks & waiting for your feedback.

SOURCE: 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.

Have a juki tension top and bottom loose,top tension mechanism tight what do i do?


Remove the thread from the machine. ALWAYS RAISE the presser foot and re-thread from the beginning. Verify that the thread follows the correct path. Set the upper tension to the midway point between high & low number.

Re-install the bobbin (make sure it turns the correct direction in the bobbin case). Thread the bobbin thread through the bobbin tension.

Test your machine.

My Juki LU-563 stopped picking up the bobbin thread, changed needle, took out bobbincase to look for thread, none, still won't sew because of bobbin thread not being picked up.


If you've properly installed a brand new needle that is correct for the machine, threaded it correctly, checked that the bobbin is installed correctly and the bobbin tension threaded properly, most likely the machine is out of time. In other words, the needle is arriving at the bobbin at the wrong time in order to intercept the bobbin. (You can open the bobbin area, hand rotate the handwheel and watch how and where the needle moves in relation to the bobbin to see where and why it is not connecting.) You can search the internet for web sites and videos that discuss machine timing or you can take it for service.

Juki DDL 8500: Bobbin thread is not coming up to the top side and the top thread is looping on the underside. Bobbin thread slides right out, and I've had no luck adjusting the top thread tension.


What thread are you using and what are you sewing? I'm assuming the machine is stitching correctly and it is just a tension issue. I would test each thread seperatly by hand and see if one thread is too tight or too loose. Thread on the bottom usually mean the top thread is too loose however it could by the bobbin is too tight. It could also indicate a slight timing issue or a burr on the hook. Is the thread shredding or getting damaged?

Back thread loose and loopy - tension


If you have the instruction manual, you might read the chapter which describes the proper adjustment for threads and fabrics.
If you do not have one, try to find it on eBay. It is the huge source of everything.
