1. Remove the front cover, and turn the power on while pressing [SW3] and [SW4] on the main PCB assembly.
2. Press [SW4] four times (select test mode "4" and then "" when the front cover is attached) to move the needle bar
to the left base line.
3. Turn the power off.
4. Remove the 2 flat screws (M4), and then remove needle plate A from the feed base.
5. Turn the pulley by hand to lower the needle bar to the limit.
6. Loosen the 3 socket set screws (FT, M5X5) securing the lower shaft pulley D.
7. Move the lower shaft pulley D and the lower shaft A assembly so that the right edge of the needle is aligned with
the tip of the outer rotary hook when the needle bar is raised 2.9 to 3.3 mm from the reference line of the lowest
point. (Set a ruler on the left side and measure the distance.)
8. Tighten the 3 socket set screws (FT, M5X5) to secure the lower shaft pulley D.
