d) Tension adjustment of the take-up lever spring
If you unfasten the nut① in the thread-adjusting device shaft and turn it clockwise at the face groove of the thread-adjusting device
shaft② using a screwdriver, the tension of the take-up lever spring③ will become stronger, and weaker when turned counterclockwise.
e) Timing adjustment of the take-up lever spring
If you loosen the stopper screw ④ and move the guide plate⑤ of the take-up lever spring in a clockwise direction, the operating timing
of the take-up lever spring③ will become faster, and slower when turned counterclockwise.
※ The standard operating timing of the take-up lever spring is when the stopper screw④ comes to position at the center of the guide plate ⑤.
