以用 键来进行。抓线装置OFF时，自动进行低速起
动。
（注意）
1. 存储器开关NO.35设定为1（禁止）时不进行抓线
动作。同时， 键无效。
2. 关于存储器开关请参照【8】存储器开关的使用方
法。
* 使用抓上线时的注意事项
(1)有（动作）抓线时，请把缝纫开始上线的长度调
小之后再使用。
机针长度过长的话，布料背面的线会被拉出。同时，
过长的话，容易把上线抓线的上线端头缝进缝迹里。
1）有抓线时的机线长度约为33-36mm。
2）更换机线之后等机线长，或用手拿机线缝制时，
请把抓线 键设定为OFF。
3）如果抓线夹持的上线被缝进缝迹后，请不要强行
拉布料，请用剪刀等把缝进布了的上线剪掉。开始缝
制的上线不会被缝进缝迹里。

6.抓线装置 hread clamp deviceT
Trouble of sewing (slip-off of needle thread, stitch skipping, or
stain of needle thread) at the time of highspeed start can be
prevented with the thread clamp device. The thread clamp
device works in the state that the thread clamp indication LED
lights up and does not work when the LED goes off.
Changeover of ON/OFF motion is performed with key.
When the thread clamp device is OFF, the start automatically
becomes the slow start.
(NOTE)
1. When memory switch No. 35 is "1" (prohibited), the thread
clamp does not work. In addition, key is ineffective.
2. Memory switch, refer to [8] HOW TO USE THE MEMORY
SWITCH.
* Matters that demand special attention when using the
needle thread clamp device
(1) In case of with the needle thread clamp(motion), make
shorter the length of needle thread remaining on the needle at
the sewing start for use. When the length of needle thread is
lengthened, needle thread on the wrong side of material is apt
to protrude. In addition, when the length is excessively
lengthened, the end of needle thread held by the needle
thread clamp may be rolled in the seams.
1) In case of with the needle thread clamp, the standard of the
length of needle thread is 33 to 36mm.
2) When needle thread is long after replacing thread or the like
or sewing while holding needle thread by hand, turn OFF the
THREAD CLAMP key.
3) When the needle thread held with the thread clamp is rolled
in the seams, do not draw the material forcibly and cut the
connecting needle thread with the scissors or the like. The
seams are not damaged since it is the needle thread at the
sewing start.
