10-3.Adjusting the driver needle guard
Turn the machine pulley to align the tip of the rotary hook with the needle center line. Then loosen the set
screw w and turn the eccentric shaft e to adjust so that the driver needle guard q contacts the needle.
If the needle contact pressure is too great, skipped stitches may occur. On the other hand, if the driver needle
guard q is not touching the needle, the tip of the inner rotary hook will obstruct the needle, resulting in an
excessively high amount of friction.
10-4.Adjusting the needle clearance
Turn the machine pulley to align the tip of the rotary hook with the needle center line. Then loosen the set
screw q and turn the eccentric shaft w to adjust so that the clearance between the needle and the rotary hook
is 0.01 - 0.08 mm.
10-5.Adjusting the shuttle race thread guide
Install the shuttle race thread guide q 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 is in the wrong position, thread breakages, soiled thread or catching of the thread may
occur.
