Lower Looper Threader

Automatic Rolled Hemming
Can be created quickly and easily with built-in fingertip control. There is no need to change the throat plate or foot

Cutting Width
Can be adjusted quickly for perfect seams and rolled edges

Adjustable Stitch Length

Differential Feed
Is easily controlled and adjusted by a dial located on the exterior right hand side


  • The lower looper threader makes lower looper threading easy. Threading can be done simply by pressing the lever, hooking the thread around the hook, and then operating the lever (MO-114D only).
  • It is possible to switch between roll hemming and narrow overlocking in one step simply by operating the nob for switching the darning width.
  • The position of the side cutter can be adjusted easily with a dial. The space between the needle and the cutter can be adjusted by turning the knob, depending on the type of fabric used or the condition of the stitches, such as when the edge of the fabric curls up or when there is extra thread.Other features
  • Presser foot pressure can be adjusted by turning a dial, according to the type of fabric used.
  • A lamp is provided to illuminate the area around the needle.
  • There is also an optional two-thread attachment for two-thread sewing (included as standard on the MO-114D)Sara, we recommend the latest model Juki MO 114D 4 thread serger below because of the easier lay in thread tension system that do not fail to register thread tensions, whether threading or operating the machine. The much older model MO654D model can require that you pull each threads through the needles and loopers to make sure the thread is all the way down between the tension discs before sewing. The main problem is the upper left round tension knob that does not have enough angle in the threading path to naturally pull the thread in between the tension disc by itself. Raise the presser foot. On the Juki MO 114D the tension is automatically released, so the threads fall down between the tension discs without having to be pulled through. The MO634 and all other Juki home sergers with round tension knobs do not have a tension release mechanism when the presser foot is raised. Hope this information helps. Thanks. John
