7.6.3 Adjustment of the presser foot timing
[NOTE] The presser foot up and down movement during the sewing synchronizes with the needle up
and down movement． With changing this synchronized timing to the sewing materials，the skip stitches can be prevented or the seam tightness can be improved． For example，the delay of the presser foot timing against the needle movement prevents the skip stitches especially to the thin materials，and the advance of the presser foot timing can improve the seam tightness especially to the thick materials．

(1) Remove the link cover (2) Loosen the setscrew “C” of the eccentric cam (3) Turn the sewing machine pulley by hand and stop the needle bar
the setscrew “A” of the eccentric cam is the standard position for the eccentric cam
(4) Loosen the setscrew “A” of the eccentric cam (5) Hold the eccentric cam
machine pulley to the arrow direction “D”，the presser foot timing against the needle movement is delayed，and if turn the pulley to the opposite direction，the timing of the presser foot is advanced．

7-17 Adjustment of the upper thread te nsi on r el ea se

[NOTE] (a) The upper thread tension release works when the upper thread is trimmed automatically or the
presser foot is lifted during the work holder feeding.
(b) If the upper thread tension release does not work properly when the upper thread is t rimmed
automatica lly, the thread tail fr om the needle becomes shorter then, it induces the ski p stitch happening or pulling the thread tail out of the needle at the start of the sewing.
(c) During the sewing operation, the discs
presser foot is moving up and down. If the discs loose and the proper stitch condition can not be obtained.
(d) When the upper thread tension release is activated, the discs
regulator opens 0.8～1.0mm. This is the normal conduction of the discs adjustment, take the following procedure.
