B. How to set the thread release stopper
ⓐ Remove the thread release return spring.
ⓑ After unfastening the thread release stopper screw, adjust the trimming drive link and the thread
release lever pin 0.3mm apart from each other. Then, attach the arm to the thread release stopper
completely. When the thread release stopper is pushed to the right, the space between the
trimming drive link and the thread release lever pin is reduced. And it is enlarged when the
stopper is pushed to the left.
ⓒ Hang on the thread release return spring.
[ Caution ]
Use a tool when removing or attaching the thread release spring to prevent accidents.
C. How to adjust the opening capacity of the thread guide dish
ⓐ Unfasten the thread release control plate screw.
ⓑ Open the thread guide dish by operating the trimming devices.
ⓒ Adjust the opening capacity to 0.6~0.8mm for normal material and 0.8~1mm for heavy material. To
increase the opening capacity, widen the angle between the thread release plate and narrow the angle
to reduce the opening capacity.
ⓓ Tighten the screw after the adjustment.
[ Caution ]
If the dish is not opened appropriately, the amount of remaining thread may be not enough or not
regular, and the dish may not be closed completely.
