Turn the pulley by hand to lower the presser foot to the down position, and then proceed with the steps below.
1. Loosen screw (1), set the bottom of the presser foot
(2) lightly against the work piece, and then tighten
screw (1).
Note
If the presser foot is lowered too far, the work piece will
shift when sewing. Also, if the presser foot is too high,
skipped stitches may occur.
