Product features

Basic performance

  • Stable thread cutting performance from thin to thick threads

    The meshing of the fixed female and the female linearly moving in parallel with the feed dog enables excellent cutting of thread from fine to thick threads (#8).

  • Reverse needle raising function (when using Limiservo X)

    After thread cutting, the reverse function of the sewing machine can be used to prevent the needle from coming out from the holder and to ensure the holder is raised to 16mm. This function ensures easy insertion and removal of thick materials.

  • Stitch adjustment dial with lock

    Reliably prevents stitch change problems during sewing.

  • LE-FA - Automatic presser bar device (optional)

    By attaching LE-FA, presser bar can be performed by using the pedal motion.
    It reduces the burden on the knees of operators who work in a sedentary position.
    This product is indispensable for standing work.
