5) Adjustment of presser foot tension

If the sewing material is in good condition, it is better to
have as little tension as possible on the presser foot.
Loosen the presser bar nut① and turn the presser bar screw
② with a coin to adjust the tension of the presser bar. Re-
tighten it afterwards.
Tension will become stronger if the screw② is turned
clockwise, and weaker if turned counterclockwise.

[ Warning ]
Be sure to turn the power switch off before adjusting the

center of the needle passage of the presser foot.
