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.

SOURCE: 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.

Not getting sufficient power from foot pedal. Sews extremely slowly... changed electrical outlets but still hardly enough energy getting to machine. Checked all plug-ins.


If your machine is an older mechanical machine, most likely it is seizing due to old oil that has dried out and locking the moving parts. If this is the case with your machine, AVOID using your machine until the problem is addressed or the motor could be damaged with further use.

Wheel on right side that controls the needle up and down is very tight...

The other thing to check are the carbon brushes. There may be some in the motor and/or the foot control unit. Over time, these carbon brushes will wear down until they no longer make the appropriate connection. If you are mechanical, you can usually order replacement brushes for your machine for ~$15 and replace them yourself. Be sure to confirm the brushes your order are for your make/model machine.

Where are the carbon brushes located on the Juki 654 serger?


In the following parts list, on page 13, it shows item #5 as carbon brushes in the motor. Carbon brushes would normally be in the motor or perhaps, the foot control, but there don't appear to be any in the foot control unit.

Here's a parts list for your machine:

Hi, I have a PFAFF Hobby 420 sewing machine. Its motor is not working and there is no service centre of PFAFF in our city. Could you please guide me opening the motor??


Maybe it just needs new carbon brushes. My Bernina 830 Record resembles the Pfaff very closely. I had issues with the motor stuttering. Changed the carbon brushes and it runs like a top!

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.

We have a Juki MO 804 Overstitch/serger machine, while it is turned on but not sewing the motor makes a squealing noise like a slipping belt. Is that what it is or should I worry about something else


if its on and not running then its most likely a motor bearing or an incorrectly adjusted clutch ( large bolt on the right side of the motor ,from front of machine) loosen lock nut ( 17, or 19 mm) and adjust bolt until the noise goes away.
