3、针距调节
3、stitch length adjustment
机器针距可以在 1.5mm-4.5mm 范围内任意调整（实际缝料线迹长度，随布料
的种类和厚度有所不同），缝纫机针距的调节是通过旋转针距调节旋钮调节的，顺
时针旋转，针距变大，逆时针旋转，针距变小。
Machine stitch length can be adjusted within the range of 1.5mm-
4.5mm (actual sewing stitch length, depending on the type and thickness of
the cloth). The sewing machine stitch length is adjusted by rotating the
stitch length adjusting knob. Clockwise Rotation, needle length becomes
larger, counterclockwise rotation, stitch length becomes smaller.

please turn off the power supply, confirm the motor really stop running
again then operate !
4、差动的调节 Differential regulation
差动调节范围在 0.8-1.3 内，松开调节螺钉，上下扳动，往上是顺差动，往下是逆
差动。Within differential range of 0.8-1.3, loose and adjust screw, throw up
and down, up is To Shrink, down is To Stretch.

5、压脚压力调节 Adjust presser foot pressure
请把压脚压力在缝迹稳定范围内尽量调弱
调节压脚压力时，拧松压脚调节螺母，并将压脚调节螺杆顺时针或逆时针旋转，顺
时针旋转则压脚压力变大，逆时针旋转，则压脚压力变小。
It should be as light as possible, yet be sufficient to obtain the proper
stitch formation.
When adjust pressure for presser foot ,loosen adjusting screw presser
foot , and make presser foot adjusting screw clockwise or counterclockwise

13 / 51
rotation, when clockwise, the pressure of presser foot is Heavy, when
counterclockwise, the pressure of presser foot is Light.

6、线张力调节 Thread tension adjustment
夹线器按照布料、线、线迹宽度的不同，及使用条件的变化而变化。对照使用条
件，调整夹线器的螺母，顺时针方向转，线紧；逆时针方向转，线松。
Thread clamp device according to the different fabric,thread and width of
the thread, and the changeable conditions of use. Controlled conditions of
use, adjust the nut thread clamp device, turn clockwise, tight thread; Turn
counterclockwise, thread loose.

7、滤油器的检查和更换 Inspect and replace oil filter
过滤器有灰尘在上面，不能正常使用，每使用 6个月后请进行检查或更换。
注：如果油按规定的油量加入，油窗喷出的油量异常、过弱、有气泡等现象时，请
及时更换或清扫过滤器
There are dust on oil filter, it couldn't normal use, every six months for
inspection or replacement, please.

1、冷却器导线器的调整
松开紧定螺钉，把各导线杆高度调整为图示的尺寸，然后拧紧紧定螺钉（图7-1），
针对不同布料时可通过调节A、B、C的高度来调节挑线量，导线杆的高度增加挑线
量减小，导线杆的高度降低挑线量增加（图1）。
1、Cooler wire guide adjustment.
Adjust the release needle thread guide hight to the number below ，then tightening screw
（Figure7-1），Accounting to different fabric, we can change thread taking up length by
adjusting needle thread guide hight A、B、C，Thread taking up quantity increase when
needle thread guide hight decrease and thread taking up quantity decrease when needle
thread guide hight increase.（Figure 1）。

2、松开紧定螺钉，左右移动针线操作器，如图 2所示，把针线操作器边缘到摆动
挑线杆轴的中心调整至 80mm，然后拧紧紧定螺钉，针对不同布料时可通过调节
针线操作器边缘到摆动挑线杆轴的中心的距离来调节挑线量，针线操作器边缘到摆
动挑线杆轴的中心的距离加大，挑线量减小，针线操作器边缘到摆动挑线杆轴的中
心的距离减小，挑线量加大（图 8-2）。
2、Release set screw，shuffling the needle thread operator，showed by
figure 8-2，change the distance between margin of needle thread
operator and center of shuffing release pole rod to 80mm, then tight the
set screw. For various type of fabric, we can adjust the thread taking up
length by change this distance. The distance between margin of needle
thread operator and center of shuffing release pole rod increase, the
thread taking up length decrease. Also, the distance decrease, the thread
taking up length increase.

3、分布导线器的调整
分布导线器①在最高点时，松开紧定螺钉③，分布导线器的导线线道里侧上端调整
成与分布导线器的长槽下端一致，然后拧紧紧定螺钉③（图 8-3）。
3、Adjustment of spreader thread take up
①at the top point，release set screw③，make the top of inner guide line fix to the
bottom of guider slot, then tight the set screw ③（Figure 8-3）。
