11) Adjusting the auxiliary presser foot and upper feed presser foot
The auxiliary presser foot ① and the upper feed presser
foot ② move up and down by turns.
When the auxiliary presser foot ① and the upper feed
presser foot ② come to their highest positions, either set
them at the same height or lower the height of the upper
feed presser foot ① by a small degree. For adjustments,
bring the thread take-up lever to the lowest position, push
down the presser bar lifter ③, unfasten the crank-fixing
screw ④ and move the adjusting crank ⑤ left and right.
(When moved to the left, the lifting amount of the upper
feed presser foot will become smaller.)
