3.  Pass the thread through the slot (2) and pull it out from the thread hole (3). 

4.  Check that the bobbin turns in the direction of the arrow when the thread is pulled.

turning the thread tension nut (1) until the bobbin case will 

not drop by its own weight while the thread end coming out 

of the bobbin case is held.
