How to thread a juki MO-352 sub class 17 serger


There are a lot of questions on the industrial sergers. The problem is, they are all just different enough, that I can't answer your question directly. You can try this website: http://www.sewusa.com/Threading_Diagrams/Threading_Pages/Juki_Sewing_machine_threading/Juki_MO_2504_2514_2516_Threading_Diagram.htm
on a similar machine, or find your nearest industrial machine dealer and ask them how to thread it.

My Juki MO-655 serger will sew a few inches then the needle thread becomes disengaged in the stitch process. The machine will sew a few inches more then stops making stitches. I have cleaned the thre


Make sure you are threading the machine correctly. Make sure you are using serger thread that isn't old. Make sure you are undoing all the threads when it breaks and thread it from the beginning.

Make sure you have the right needles in their respective places. My Juki MO has two different size needles.

How to thread a juki serger sewing machine. i need a large diagram of how to do it. thank you


do you know what model Juki it is? Is it a serger or a sewing machine? Juki do industrial straight, serger and specialised machines such as coverstitch and blind hemmers as well as domestic sewing machines and sergers so there is a big range of machines.

There are manuals at this site for http://jukihome.com/products/mo644d.html various models of Juki Home sergers, but you will need to hunt through and find your model.

The manual is on the "features" tab for each model so just dig down a bit to locate the pdf file in there.

I hope this is what you were searching for.

Don't know how to thread the juki mo-735 serger


This video starts off a little ****, but expected if you have ever visited the Threadbanger site - http://www.metacafe.com/watch/1462325/how_to_use_a_serger_indie_pendent_designer_spotlight_thread_he/ Not your brand, but the same "serger basics". Lift the antenna to it's highest position. Set the tensions to zero. Have the presser foot up when threading. Raise the upper looper to it's highest position. Sergers are great little machines, but they can be nerve racking when it comes to threading. After years of threatening my old FunLock, I bought a Babylock Imagine with air-jet threading - what a relief!

Good diagram showing how to thread a 4 thread Juki 644d serger we do not have a manual machine is not clear


You can download a free threading guide here - http://www.sewusa.com/Threading_Diagrams/Threading_Pages/Juki_Sewing_machine_threading/Juki_MO_644_Threading_Diagram.htm

The same site also sells manuals.

Threading Tips:

Have the thread antenna at it's highest position.

Set the tensions to zero.

Have the presser foot up while threading.

When you thread a serger for the first time, or if you are having a threading problem, use a different color thread for each guide. This can quickly indicate where the problem lies.

Once the stitch is satisfactory, change to the color you prefer - but this way is the easiest - cut the thread near the thread cone and tie off with the new thread. With the tensions at zero, slowing run the serger until the new thread appears. You will need to stop as the knots approach the needles and thread them by hand.

Do the tie-off before running out of thread and this will save a lot of time and stress.

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.

2nd needle/4th thread - threading confusion


With some sergers, but not many (singer 14u64 comes to mind), the top of the stitch will be an overedge that mates with the right needle thread, and the left needle thread will appear as a separate straight stitch. When you look at the underside of the stitch, the overedge will go all the way over to the left needle (the full width of the stitch). This is normal if you have this type of machine. Another stitch some sergers do (2/4 thread sergers) is a 2 thread chain thal looks like a lone straight stitch on both sides, and a 2 thread separate overedge.

As far as the threading of the takeup, it totally depends on your model. Always post your model number when you have questions as sergers vary greatly in design.
