Place the feed dog gauge under the presser foot with its recess facing downwards.
Lower the presser foot onto the gauge.
Loosen nut 1 and turn screw 2 out a few turns.
Move the knee lever to the right until a noticeable resistance is felt, making sure that the
presser foot is not lifted off the gauge, and hold it at this position.
Turn screw 2 in as far as it will go, then back out by one turn, and lock it in place with
nut 1.
