SEWING IN REVERSE
When you wish to sew backward to tie the threads at the beginning or end of a seam,
press in the button R, 7, Fig. 1, as far down as it will go. The machine will sew backward
as long as the button is hold down.
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. 13) to the
right. To decrease, turn to the left.
Before adjusting lower tension be sure that the machine is
threaded properly. When necessary to change the bobbin ten
sion, turn small screw (Fig. 14) 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. 15).
When the upper tension is too tight, the lower thread is
pulled up over the upper thread which is lying flat on the fabric
( Fig. 16). When the upper tension is too loose, the upper thread
forms loops over the lower thread lying flat on the fabric
mg. 17).
