Treadle to Electric (Using Terminal box #700)

Treadle or Electric to Hand Crank

Treadle to Electric

Many sewing machines were designed to be operated by treadle or electric.
If you presently have a treadle and wish to convert to electric, the machine MUST have a built on motor mount. The motor mount can be found on the right portion of the machine head below the hand wheel (see arrow). This is part of the casting and cannot be added.

    Conversion to Hand Crank


    To install Hand Crank (part #KS-1) you MUST have a built on motor mount (see arrow) as mentioned in the treadle to electric conversion. You MUST also have a spooked hand wheel (part #15282). The handle flips down and out of the way for storage.

    Portable Knee Control to Electric Foot Control


    Sorry to say knee controls are no longer available. An alternative is to convert to an electric foot control.



    TO COMPLETE THE CONVERSION YOU WILL NEED:


    • Foot control #204
    • Control to terminal cord #600
      66" long cord with two terminal connectors at each end.
      Attach #600 cord to #204 foot control.
      Attach the other end of #600 cord to the existing screws (marked in drawing with red circles) inside the metal plate.
      The #600 cord can be guided out through hole in the metal plate (same hole used for the light and motor cord).


    NOTE: This is the least intrusive conversion and easy to convert back should you be so lucky to someday find a knee control.
