C. How to adjust the opening capacity of the thread guide disk
ⓐ Unfasten the thread release adjusting plate screw.
ⓑ Open the thread guide disk 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 disk is not opened appropriately, the amount of remaining thread may be not enough or not
regular, and the disk may not be closed completely.
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 delay 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 delay spring to prevent accidents.
