護針片調整
1. 如 ( 圖 18) 所示，以最大針為基準進行調整，
當勾針 (A) 由右往左移，針由下往上時，護
針 片 (B) 與 針 凹 槽 下 緣 凸 起 處， 距 離 約 為
0~0.2mm，而針尖與護針器下緣距離為 3.5
±0.3mm。
2. 護針片調整步驟如下：
* 鬆開螺絲 (C) 往 X 或 Y 方向移動前後位置。
* 旋轉螺絲 (D) 可控制護針片上下位置順時
針旋轉則下降，反之則上升。
* 調整至圖示位置時，再鎖緊螺絲 (C)。
針與勾針之時位關係
勾針針尖與針孔之會合正確時位關係
以最大針為基準進行調整，當勾針由右死點往
左移至針後方左緣時，勾針尖與針孔上方距離
(A) 與勾針由左死點往右回移至針前方左緣時，
勾針尖與針孔上方之距離 (B) 均相等時，此時
即正確之時位關係 ( 圖 19)。

adjustment is operated under the biggest
needle specification. When the looper (A)
moves from right to left, and needle shift
from top to bottom, the distance between
needle guard and convex of needle concave
is about 0-0.2mm, and the distance between
needle peak and bottom of needle guard is
3.5±0.3mm.
2.Procedures to adjust Needle Guide：
* L o o s e n S c r e w ( C ) a n d m o v e f o r w a r d /
backward as per direction X、Y.
*Turn Screw (D) till able to control the up-
down position of the needle guide, the
needle will lower when turned clockwise
and the opposite is upper.
*Tighten Screw (C) after adjusted to proper
position.
TIMING OF NEEDLES AND
LOOPERS MOVEMENT
CORRECT TIMING BETWEEN THE
LOOPER'S TIP AND NEEDLE'S EYE
The adjusting bases on the biggest needle
specification .The looper moves from dead
right side forward behind the needle, approach
to the left side of needle the distance between
looper's tip and needle's eye (A), and then, the
looper backward front the needle approach to
the left side of needle, the distance between
looper's tip and needles' eye (B). When A=B,
the timing is correct. (Fig. 19)
