I need replace thread holder for Juki MO-644D serger


Good luck. I found a replacement part for one of mine on Ebay. Just search for Used Juki Serger for parts. Maybe you'll find a 644D for cheap enough that you can scavenge parts for a few more years.

I want to adjust my serger yuki mo 2516n but i don't still have it's manual instructions


if you go to this page http://www.juki.co.jp/household_en/serger/index.html there are the current household sergers from Juki and a four page threading diagram for them showing the different stitch set ups.

If your serger is a domestic one too (the MO in front makes me think so) then you may find that the threading up is very similar on your model. Stitch length is usually a kob on the right marked from 0.5 to 4 and differential feed knob is usually there too, usually marked from -0.5 up to 1.5. Tension settings are usually around 5 but you adjust the looper tensions to suit the fabric and how wide you are trimming it with the blades.

You could contact Juki or their local distributor in your country and arrange to purchase manual for your model. http://www.juki.co.jp/household_en/dl/index.html this page gives a listing for countries.

it is also available on line to purchase as a black and white pdf file, http://www.sewusa.com/Sewing_Machine_Manuals/Juki_Manuals/Juki_Industrial_Sewing_Machine_Manuals/MO-2500_Instruction_Manual.htm for $8USD

JUKI MO 134 SERGER


How to Thread Juki MO-134 Serger from watching lady at Lyles. Turn upper blade up. Push in first then turn up.It makes threading easier. Blue Thread upper looper first. Pull thread through tension knob. Don'tjust lay it there. (She thought that is what I must have done) Orange Thread lower looper next. Pull thread through tension knob as inthreading upper looper. Adjust lower looper so it is right nextto upper looper so that their points are almost together and directly belowsewing needles. Lower looper will be in front of upper looper (I believe). With tread from upper looper pulledback, slightly lift lower looper above upper looper and thread. I think this isright. Pull thread back with other thread. Tension is the key. Remember that. Yellow: Thread left needle first.Remember tension. Pull thread through curled wire on left side of needle arm. Green: Thread right needle. Rememberabout tension. Pull thread through curled wire on right side of needle arm. b> Note: Before sewing turn the wheel tomake sure the stitches are going together correctly.

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.

I have a juki mo-3614 serger and I can't seem to get the blades lined up right for cutting. It just seems to want to roll the fabric instead of cut it. How do I line up the blades the right way.


first, pull out the bvlades and make surte they are sharp. It could simply be that they are dull. Next, line tyhe bottom blade up level to the surface of the needle plate. The top blade should be adjusted to where it slices against the botom blade. You may have to experiment with the height adjustment on the top blade, assuming you have a suitable cutting edge.
