送布齒在最高位置時，送布齒齒尖面
與針板面平行，且此時主送布齒(A)與
差動送布齒(B)，高度相同，且齒面高
出針板面1.0~1.2mm。(圖24)
H 送布齒高度調整：
When the Feed Dog rise up to the
highest position, the surface of Feed
Dog and Needle Plate must be in
parallel. Besides, the teeth of Main and
Differential Feed Dog must be aligned.
The standard height of Feed Dog is
about 1.0˜1.2mm from its top teeth to
Needle Plate. (Fig. 24)
H.
ADJUST THE HEIGHT OF FEED DOG :
1. 當針從最高點下降時，左針大約位於
勾針後面之一半的位置時(圖25)，勾
針線必須脫離凸輪(P)之最高位置。
2. 須調整凸輪時，放鬆22個螺絲(1)調
整之。
I 勾針控線凸輪之調整：
1. When Needle comes down from the
highest position, and the left Needle
reaches around 1/2 position of the
Looper. (Fig. 25)
The looper thread will come over the
highest position of Thread Cam (P).
2. Loosen the two screws (1) for above
adjustment.

注意：
下切刀組安裝於機器前須先檢查切刀
組之相關位置和滑順度及切線效果。
1. 當活動刀片往右移時，右邊刀口之尖
端(A)與固定刀之前端(B)須對齊。
且活動刀移至最右點時，左邊刀口
和固定刀前端的契合度為1.0mm。
調整時可放鬆螺絲(C)移動固定片。
(圖26)
2. 夾線片(D)之邊沿須與活動刀右邊刀
口內沿切齊，如(E)。可由螺絲(C)調
整。壓力片(F)前端與固定刀前端之
距離約為1mm，調整時，可放鬆螺
絲(G)移動壓力片(F)。(圖27)
