Push bobbin winder latch against bobbin until it clicks.

Checking tensions
To check the thread tension balance, be sure to use mercerized thread of the same size on the top and on the bobbin , and a sharp, correct size needle for the fabric you are sewing.
Begin with a full bobbin.
Set the stitch length for about 12 stitches per inch.
Fold a 6 inch square of fabric in half diagonally, forming a triangle.
Make a line of stitching 1/2 inch from the fold.
a) If seam is puckered – both tensions are too tight.
b) If the bobbin thread lays on the fabric – tighten upper thread tension and repeat test.
See figure 3 page 9.
c) If the top thread lays on the fabric – loosen upper thread tension, and repeat the test.
See figure 2 page 9.
Grasp the stitching and pull with the snap to make threads break.
a) If both Reds break – tensions are balanced.
b) If neither thread breaks – most both tensions are too loose.
c) If upper thread breaks – loosen top tension.
d) If lower thread breaks – tighten top tension.
Both threads do not have to break at the same place, but they should break it on the same snap.
It is necessary to reduce the upper thread tension somewhat when the zigzag stitching.
The wider the stitch, the less tension that is needed.
This is particularly important when making designs.
It is not desirable to have any bottom thread visible on the right side of the fabric when making designs.
