Adjustment Procedure
1) Adjustment of the thread trimming cam position
1. Assume the condition such that the thread trimming solenoid ❶ is
attracted by hand.
2. Loosen and adjust the thread trimming cam setscrew ❹ so that
the gap length becomes 2mm between the thread trimming cam
❷ and the cam follower ❸.
3. After adjustment, tighten two thread trimming cam setscrews ❹.
(Caution) After adjustment, make confirmation according to
[3.-(9)-3) Standard timing for the thread trimming
cam].
4. Apply exclusive grease (JUKI grease A) to the stopper spring part
❺.
2) Adjustment of the thread trimming link stopper screw
1. Turn the hand wheel and adjust the thread trimming roller ❺ to the
inlet section  of the thread trimming cam groove.
2. Loosen the thread trimming link stopper setscrew B ❼.
3. Move the thread trimming link stopper setscrew A ❻ and adjust the
clearance to be uniform between the thread trimming roller ❺ and
the thread trimming cam groove on both inside and outside.
4. Tighten the thread trimming link stopper setscrew B ❼.
In this case, make sure that the thread trimming link stopper set-
screw A ❻ does not move.

that the thread trimming roller ❺ enters smoothly without touching
the thread trimming cam groove.
