With the point of the looper at this position, set the clearance between the left needle and the point of the looper at approximately 0.2mm. -
Page 12: Movement
5-7 Changing the amount of the looper font-to-back movement The clearance between the point of the left needle and the back side of the looper when the looper moves to the right from the extreme left end of its travel should be 0.05~0.1mm. The clearance between the point of the right needle and the back side of the looper should be 0.2~0.3mm. -
Page 13: Position Of The Needle Guard (Front)
■ Set the clearance between the right needle and the point of the looper at 0~0.05mm when the point of the looper has reached the center of the right needle from the extreme right end of its travel.
