Threading The Machine
Now, one of the ways of winding the bobbin follows the dashed line next to the 1 toward the right. To thread the machine, follow the solid line under that hook and around the back loop and down through arrow 2.
Keep following the arrow up around the curve at 3 to point 4 in first picture above. At the 4 arrow is a tensioner arm that the thread needs to be looped through before pulling the thread back down at point 5. Here the thread continues down to loop behind a final thread holder at point 6 and threading the needle.
Most sewing machines include guiding arrows for threading making this the easiest part of set up when preparing to sew. The Machine is no different.
