ADJUSTING THE TENSIONS
A l w a y s 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 ma­
chine is threaded properly. When necessary to change
the bobbin tension, turn small screw (Fig. 14) on side
of the bobbin case clockwise to tighten, counter­
clockwise to loosen.
When the upper tensions are properly balanced, a
p > a r f a o t stitch will be formed with both threads inter-
iocking 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. 1 6 ) . When the upper tension is
too loose, the upper thread forms loops over the
lower thread lying flat on the fabric (Fig. 17).
