The Juki MO-1000 Overlock Serger redefined ease-of-use with its Jet Air Looper Threading System. A simple push of a button releases a powerful burst of air, automatically threading the loopers in seconds—making it one of the most user-friendly sergers ever made.

Beyond threading, Juki integrated thoughtful upgrades like a redesigned knife system for sharper, smoother curve sewing and a more open sewing area for better fabric handling. The automatic needle threaders eliminate eye strain, while LED lighting brightens your workspace for accuracy and comfort.

Additional premium features include differential feed for smooth seams on any fabric, lay-in tension dials for simplified tension adjustments, and a sleek build that delivers both performance and reliability.

Features

  • Looper Air Threading: Using the new easy threading feature, easily thread the machine from the threading hole to the looper with the power of a strong whoosh of air sent from the electric motor. This amazing function dramatically alters upper and lower looper threading.
    Step 1: Insert from 1/2 inch to 1 inch of thread into each threading hole at a time.
    Step 2: Press the air-control pushbutton and you are done! The MO-1000 was just simply threaded by air.
  • Automatic Needle Threader
    Step 1: Lower the threading lever.
    Step 2: Hook the thread.
    Step 3: Release the lever to complete the threading.
  • NEW! Upper Looper Converter 2-/3-Thread Conversion
    Switch to 2-Thread sewing simply by pushing the 2-/3-thread changeover attachment to the left, making this operation even easier.
  • Adjustable Differential Feed: Even with easily stretched fabrics such as knits and georgette, create beautifully sewn finishes by adjusting the differential feed with the simple dialing of a knob. Adjustments can even be made while sewing.
  • Ample Fabric Throat Area: The height of the throat is 72.4 mm. Due to this increased height, the usability of the work space has improved infinitely.
  • LED Sewing Light: The needle area is brightly illuminated. The long-life, energy-efficient and eco-friendly light will not heat up, even after a long period of continuous use.
  • Amazingly Quiet Operation: The sound reducing design minimizes operating noise and the MO-1000 sews with less vibration.
  • Easy Stitch Length Adjustments: Change the stitch length for specialty thread or overlock techniques using the conveniently located dial.
