①挑線簧的挑線量
挑 線 簧 R (1) 和 L (2) 的 標 準 挑 線 量 是
7mm。
挑線量的調整是改變挑線量限位器 [ 右 ]
(3) 和 [ 左 ](4) 的高度。
* 挑線量限位器 [ 右 ](3) 和 [ 左 ](4) 的高
度在夾線軸 (5) 的中心狀態時就是標準

● When replacing consumable parts such as the rotary hook and
knife.
If the power switch needs to be left on when carrying out some
adjustment, be extremely careful to observe all safety precautions.
