Thread jam removal tool to help remove thread caught in the rotating hook assembly. Fits most all Singer Featherweight 221 models as well as the 222 hook assemblies... For the common hook assembly style.
Instructions are as follows:
- Remove the needle throat plate.
- Place a towel between the faceplate and bed extension; stand the machine on its handwheel end.
- Insert the Thread Jam Removal Tool over the bobbin case base post, ensuring that it is flush against the base.
- While holding the handwheel, turn the tool clockwise until there is no resistance.
- Inspect the bobbin case base for any thread that may have been expunged - it is often a very small piece.
- Reinstall the needle throat plate, making sure the positioning finger is in the gap on the underside of the throat plate.
