2. Refer to the stitch chart on the machine or in this manual for recommended stitch length and width settings for each pattern.

5.2 Stitch Length and Width Adjustment

• Use the stitch length dial to adjust the length of your stitches. Shorter lengths create denser stitches, while longer lengths create looser stitches.
