4.12 Chaniging the looper
The looper can be removed after loosening clamping screw 175.0403 (Cl. 141-
40/-50) (Fig. 12) and 172.0403 (Cl. 141-23/-30 and 142-30/-40) (Fig. 12a)
respectively, at looper shaft head.
Upon mounting a new looper, take care that it touches the needle neither in its
front position nor in its rear position. (Also refer to setting data)
The wide gripper back should be standing as parallel as possible to the needle.
