•
For adjusting the
gap between the
needle and the hook
body, bring the
books(P) supporting
the arm to the
handwheel side as
shown in Fig.2-11
for the purpose of
preventing a change
of the gap between
the needle and the
hook body due to
the deformation of
the arm.
12. Set the part(Q) of the hook race body(unit) and
hook body tip(R) to the phase shown in Fig.2-12
approximately.
13. After fixing the hook body, turn the lower
shaft gear in the arrow 1 direction until it
touches the wall as shown in Fig.2-13 and
lightly press it to the hook shaft gear by
shifting it in the arrow 2 direction.
Turn the lower shaft front bushing in either
direction, and tighten socket screw(K).
