1. Adjusting the height of the needle bar
Bring needle bar (1) to the lowest position of its stroke. Loosen needle bar connection screw (2) and adjust so that upper
marker line (4) engraved on the needle bar aligns with the bottom end of needle bar bushing, lower (3). For F type only,
adjust the needle bar to the position where it is lowered by 0.8 mm to 1 mm from the center of upper marker line (4)
engraved on the needle bar.
Turn OFF the power before starting the work so as to prevent accidents cause by
abrupt start of the sewing machine.
After the adjustment, make sure that there is no uneven torque. When stitch skipping occurs in accordance
with the sewing conditions, adjust the height of the needle bar so as to lower it by 0.5 to 1 mm from the
needle bar engraved line (4).
2. Adjusting the needle-to-shuttle relation
1. Turn the handwheel by hand. When needle bar (1) has
gone up, adjust so that lower marker line (2) engraved
on the needle bar aligns with the bottom end of the nee-
dle bar bushing (3), lower.
Turn OFF the power before starting the work so as to prevent accidents cause by
abrupt start of the sewing machine.
2. Loosen setscrew (1) in the driver. Open inner hook
pressers (2) to the right and left, and remove inner hook
presser (3).
At this time, be careful not to let inner hook (4)
come off and fall.
