3. 夾線彈簧片的壓力調整：
當下勾針線被切斷後，下勾針這端之
線頭須被夾線彈簧片與活動刀片穩定
夾住。調節夾線彈簧之壓力，可由螺
絲(H)旋轉調整。(順時鐘方向壓力愈
強，反時鐘方向壓力變弱)。(圖28)
注意：
夾線彈簧片之壓力調整須適中，壓力太強會
減短活 刀片之壽命，壓力太弱則下勾針線頭
易脫落。壓力之強度以能輕易切斷線即可。
3. When the looper thread has been cut
off, the Clamp Spring and Moving Knife
will clip the thread in stable. To increase
the pressure of clipping thread turn the
screw (H) clockwise and decrease the
pressure turn the screw (H) counter-
clockwise. (Fig. 28)
Remark :
The pressure of Clamp Spring must be moderate﹒
If the pressure has been adjusted into too
strong, it will decrease the life of Moving
Knife﹒ If the pressure has been adjusted
into too weak, the looper thread will easy
to lose from the Clamp Spring﹒ What is moderate
pressure? It is meaning that the pressure to
cut the thread easily﹒

1. 當活動刀片 ( A ) 往左邊移時，必須通過針
線之線環 ( B ) 。(圖33-1)
2. 當活動刀片往左移至左定點時，下勾針
線(C)須滑入活動刀片(A)之左邊刀口(D)
內。(圖33-2)
3. 活動刀片往右回移時，活動刀片右刀口
須勾住針線，左刀口勾住下勾針線，一
起往右拉回。(圖33-3)
4. 針線及下勾針線由活動刀片拉回與固定
刀切斷，針線切斷後自然脫落，下勾針
線靠下勾針一端線頭須穩穩夾住於切刀。
(圖33-4)
C 下切刀組與針線及下勾針線之關係：
1. When the Moving Knife (A) move to the left
which must be passed the loop (B) of needle
thread. (Fig 33-1)
2. When the Moving Knife move to the left dead
point which looper thread must be dropped
into the left hook (D) of Moving Knife (A).
(Fig.33-2)
3. When the Moving Knife move to the right, the right
hook of Moving Knife must hooks the needle
thread and left hook must hooks the looper thread
to pull into right side in same time. (Fig.33-3)

Status 7 : The thread wiper can't take the needle
thread up -
Solution :
(a) Please double confirm the bottom trimmer have
always cut the needlethread. If the needle thread
didn't be cut out, the wiper is impossible to take
the needle thread up.(*)
(b) Please check the position of thread wiper have
followed the installation manual to set up in
correctly.
(c) Please check the return elasticity of top wiper
is too weak, or the wiper didn't move smoothly.
Remark :
If the needle thread didn't be cut by trimmer which will
cause the "Top Wiper" can't take the needle thread up. Please
use the thread clipper to cut the needle thread which didn't
be cut by under trimmer. To let the "Top Wiper" return
backto the initial place which to avoid the hook of wiper
crash theneedle.

the machine didn't operate -
Solution :
(a) Please check the green light on the Under Trimmer
Position Security Switch is be switched on or off.
(The green light locate at back side of machine
head) If the green light is be switch off which
meaning is that under thread trimmer didn't return
back the position, the Security Switch have broken
the electric power in automatic which to avoid
the Looper crash the under thread trimmer.
(b) Please check the error code which be showed on
the screen of control box. then, to follow
instruction manual for solving the problem.
狀況7 ：撥線器無法將針線頭撥起時—
排除：
A 先試縫確認每次切線時，針線是否每次都
有被下切刀完全切斷；因針線未被下切刀
切斷時，撥線器則無法順利將線頭撥離針
板面。
B 檢查撥線器，安裝之位置是否有依前述說
明正確安裝。
C 檢查撥線器，回歸時彈力是否異常太弱，
有活動不良的情形。
註：
如是針線未被切斷導致撥線器無法將線頭拉出而卡
在針下方時，必須先用剪刀剪斷針線，使撥線器之
撥線勾針能回歸原點，否則會造成針與撥線勾針相
互碰撞的情形。
狀況8 ：前踩踏板、機器不能運轉時—
排除：
A 檢查保護下切刀組回歸定位之安全開關小
綠燈是否亮著(位於機頭後方，安全開關
上)。如未亮則表示下切刀組未回歸定位，安
全開關自動斷電以保護下切刀不被碰撞。
B 檢查電腦控制箱顯示之代號，再對照馬達
說明書之故障代號說明，排除問題。

the Thread Trimmer System and
Pressure Foot Lifter didn't operate -
Solution :
(a) Please check the terminal of Top, Bottom Thread
Trimmer and Pressure Foot Lifter junction line
for which locate at backside of machine head.
If the terminal didn't connect well, the signal is
going to bad transmission to cause these moving
parts didn't operate.
