  1. Pull the Rotary Hook off the machine.



Reinstalling the Hook:

  1. Reinstall the Rotary Hook. There is a guide groove on the Rotary Hook that fits onto a guide pin on the Hook Adapter (Sleeve). Because of these guides the Rotary Hook can be installed without needed additional adjusting.


On the left is the guide pin for the Hook Adapter (Sleeve). On the right is the guide groove for the Rotary Hook.


  1. Tighten the three hook fastening screws (highlighted in red) while applying finger pressure pushing the bobbin post in.
