How to thread my Juki MO-114D


Am unable to locate any videos online.

Perhaps the manual would be helpful. If you are having problems seeing the pictures, you can enlarge them on the computer and perhaps that will help. Perhaps you can take it to a Juki dealer and ask them to show you.

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.

Juki MO-634DE Stiching


I tried to find this on the Juki website but its obviously a previous model so not much info on there. But did find it listed elsewhere as a 3/4 thread overlocker.

So I'd guess at the following, it probably seams a four thread marrow (overlock seam) made with two needles and two loopers. And a three thread overlock seam where you use either the left or right needle, this would give you either a narrow or wider 3 thread seam. Image below of 3 and 4 thread overlock seams.

Lastly, I would suggest that the D denotes Differential feed, this is a feature that controls the two feed dogs in the machine and gives you the ability to set them to move at different speeds - very handy to control the fabric feeding but also used decoratively for lettuce edging.

Rolled hem - most overlockers of 3/4 variety will also do a rolled hem; however, I can't actually confirm if this model does or not. But look around for a retractable stitch ****** in the foot or needle plate or a second needle plate in the accessory case. Rolled hemming is also very useful and most models will do it now; just variation in how you actually set it up to do so. Bernettes you flick a lever in front of the needle/foot area, earlier Elnas like the L3 and L4 you needed to change the needle plate and a little ****** in the presser foot.

Of course, you could email the local distributor for Juki in your country and ask them and this may be the best way to check. Just copy this into your browser

My juki serger mo-634de suddenly stopped working. Lights on, wheels and parts move freely, even stitching seems to work if I turn it manually, but nothing happens when I push the pedal. No sound. ...


Hi, I have the exact same machine. it sounds like the wire from the foot pedal to the machine is broken. You would still get power from the wall to the machine to light the light, but no 'gas pedal'. You could maybe get an electrian to test the connection under the foot pedal and if the wire is damaged? or maybe the part that plugs in the machine is cracked or damaged?
Good luck! Annette

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.
