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

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).
