7. STANDARD ADJUSTMENTS
BAS-311HN, BAS-326H

7-7. Adjusting the driver (needle guard) position
Turn the pulley in the direction of the arrow to align the tip of the rotary hook with the center of the needle, and then loosen
the set screw (2) and adjust by moving the eccentric shaft (3) to adjust so that the driver (1) is touching the needle.
The set screw (2) and the eccentric shaft (3) are on the right side of the bed at the rear.
NOTE:
If the driver (1) crosses the needle more than necessary, it will cause problems with the thread tension.
Furthermore, if it does not cross the needle at all, the tip of the rotary hook will interfere with the needle and skipped
stitches may occur.
7-8. Adjusting the clearance between the needle and rotary hook tip
Turn the pulley in the direction of the arrow to align the tip of the rotary hook with the center of the needle, and then loosen
the set screw (1) and turn the eccentric shaft (2) to adjust so that the clearance between the needle and the tip of the rotary
hook is 0.01 to 0.08 mm.
7-9. Adjusting the shuttle race thread guide
Install the shuttle race thread guide (1) by pushing it in the direction of the arrow so that the needle groove is aligned with
the center of the needle plate hole.
NOTE:
If the shuttle race thread guide (1) is in the wrong position, thread breakages, soiled thread or tangling of the thread may
occur.
The position of the shuttle race thread guide (1) is adjusted at the time of shipment from the factory. It should not be
changed if possible.
