14. RELATION BETWEEN ROTATING HOOK AND TAKE-UP LEVER MOTIONS
When the timing belt is removed for replacement,
the relation between rotating hook and take-up
lever motions should be as follows:
(1) Turn the balance wheel and stop it when the
take-up lever is lifted to its top position.
(2) Lean
the machine head backward and make
sure the arrow (timing mark) on the timing
belt sprocket matches the black line on the
boss of hook shaft bearing.
(3) If the timing mark is not aligned with the
black line, remove and reinstall the timing
belt to obtain proper alignment.

15. RELATION BETWEEN ROTATING HOOK AND OPENER MOTIONS
(1) Turn the balance wheel by hand and stop it
when the opener holder is the longest distance
away from the throat plate.
(2) At this time, make sure that the gap between
the bobbin case holder "A" and the opener is
approximately 0.2 mm.
(3) If the gap is too large or small, loosen the
opener set screw "B" and adjust the position
of opener.
