JUKI MO-1000

JUKI MO-1000 Air Threading Overlock Serger

Take the frustration out of serger threading with the JUKI MO-1000 2/3/4 Thread Air Threading Overlock.
Designed for easy setup, smooth operation, and professional-quality results, the MO-1000 combines JUKI’s powerful air-threading technology with convenient controls and versatile stitch options.

From stretchy knits and activewear to lightweight garments, rolled hems, and everyday seam finishing, the MO-1000 makes it easier to achieve clean, polished results.
With sewing speeds up to 1,500 stitches per minute, adjustable differential feed, automatic needle threading, and simple 2-, 3-, or 4-thread operation, this machine is a great choice for both new serger users and experienced sewists.

Thread the Loopers with the Power of Air

One of the standout features of the MO-1000 is its Looper Air Threading System.
Simply insert approximately 1/2″ to 1″ of thread into the threading port and press the air-control pushbutton.
A strong burst of air carries the thread through the looper path, dramatically simplifying upper and lower looper threading.

There’s no complicated looper threading sequence to memorize, helping you spend less time setting up your machine and more time sewing.

Automatic Needle Threader

Threading the needles is easier, too. Lower the threading lever, position the thread, and release the lever to complete the process.
This convenient system helps reduce eye strain and makes changing threads quicker and more comfortable.

Easy 2/3/4-Thread Serging

The MO-1000 gives you the flexibility to choose between 2-thread, 3-thread, and 4-thread serging for a wide variety of techniques.
The built-in upper looper converter makes switching to 2-thread sewing simple—just move the 2-/3-thread changeover attachment into position.

Beautiful Results on Knits and Delicate Fabrics

The adjustable differential feed helps you achieve smooth, consistent seams on fabrics that may otherwise stretch, wave, or pucker.
Adjustments are made with an easy-to-reach dial and can even be changed while sewing.

Whether you’re working with knits, georgette, jersey, or other challenging fabrics, the MO-1000 gives you greater control over the finished result.

More Room to Work

An increased throat height of approximately 72.4 mm provides additional working space around the needle area.
This makes it easier to position and guide fabric while sewing larger or more involved projects.

Quiet, Comfortable Operation

JUKI designed the MO-1000 to operate with reduced noise and vibration for a more pleasant sewing experience.
A bright LED sewing light illuminates the needle area without generating excessive heat, even during extended sewing sessions.

Easy Stitch and Tension Adjustments

Conveniently positioned controls make it simple to customize your stitching. Adjust the stitch length for different fabrics, specialty threads, or decorative techniques,
and fine-tune thread tension with variable settings from 1 through 9.
