the bobbin thread
Your sewing machine uses two threads to form a stitch. The upper thread comes from the spool
and is threaded through the eye of the needle. The lower thread comes from the bobbin. Wind the
bobbin before threading the machine.
• Place thread spool on left spool pin with
thread retaining slit B on top. (Break paper at
the end of spool if necessary).
• Lead thread around bobbin winder tension
disc C, as illustrated, and through small hole
in bobbin from inside out.
• Snap bobbin onto spindle and push bobbin to
right to engage bobbin winder.
Hold thread end, as shown, and start the
machine. Cut off thread end after a few coils
have been wound.
When required amount of thread has been
wound (winding will stop when bobbin is full),
stop the machine and cut connecting thread.
Push bobbin to left and remove bobbin from
spindle.
Hold hand wheel and tighten hand wheel
knob.
