ADJUSTING THE TENSIONS

Always adjust the upper tension with the presser foot down,

as the tension is released when it is raised. To increase the'

tension on the upper thread, turn dial (Fig. 15) to the right, or

clockwise; to decrease, turn to the left. The higher the nun^ber

on the dial the tighter the tension. Before adjusting lower tension

be sure that the machinp is threaded properly.

When it is necessary to change the bobbin tension, turn the

small screw (Fig. 17) on side of the bobbin case clockwise to tighten

counterclockwise to loosen.

When the upper and under tensions are properly

balanced, a perfect stitch will be formed with both

threads interlocking in fabric (Fig. 16-A)

When the upper tension is too light, the lower

thread is pulled up over the upper thread which is

lying flat on the fabric (Fig. 16-B)

When the upper tension is too loose, the upper

thread forms loops over the lower thread lying flat

on the fabric (Fig. 16-C).
