Threading the Machine
3. Fully insert the spool for the upper thread onto the spool pin. Slide the spool onto the pin so
that the spool is horizontal and the thread unwinds to the front at the bottom. Slide the spool
cap onto the spool pin.
4. Pull some thread off the spool and pass the thread under the thread guide, then behind the
thread guide cover from the back to the front. Hold the thread with your right hand so that
there is no slack in the thread after placing it under the thread guide, and then pass the thread
under the thread guide cover with your left hand.
