Maximum differential feed ratio, 2.2, is effective when
the stitch length dial is in the range of 1 to 4.0. When
the stitch length dial is set between 4.0 and 5.0, the
maximum differential feed ratio will automatically be set
between 2.2 and 1.8.
Puckering may be eliminated by reducing thread
tensions as well as adjusting the differentia! feed ratio.
