The most common cause for a seized machine is thread caught and often hidden behind the bobbin case base. Do not force the machine or severe, costly damage will occur to the hook assembly. The new Thread Jam Removal Tool makes disentangling a thread jam very easy, and it can all be done without taking the hook assembly apart! Instructions are as follows:
1. Remove the needle throat plate.
2. Place a towel between the faceplate and bed extension; stand the machine on its handwheel end.
3. Insert the Thread Jam Removal Tool over the bobbin case base post, ensuring that it is flush against the base.
4. While holding the handwheel, turn the tool clockwise until there is no resistance.
5. Inspect the bobbin case base for any thread that may have been expunged - it is often a very small piece.
6. Reinstall the needle throat plate, making sure the positioning finger is in the gap on the underside of the throat plate.
The early Featherweights from 1933 and 1934 had a different hook assembly, and they require a different Thread Jam Removal Tool. Compare the product photos with the hook assembly on your machine to be sure you select the right Thread Jam Removal Tool.
