绕线调节（图 10）/Winding The Bobbin Thread (Fig 10); 针距、倒顺送料（图 11）/ Needle Pitch, Reverse Feed（Fig 11 - Jack H2 Series Product Instruction Manual

10.绕线调节（图 10）/winding the bobbin thread (Fig 10)
1.打开电源。
2.将梭芯插入绕线轴①的底部。
3.根据箭头所示的方向，先将线在梭芯上绕几
圈
4.扳动绕线摆杆②.
5.将压脚抬起来。
6.踩下踏板，便开始自动绕底线了。
7.当梭芯绕满后，绕线摆杆②便会自动复位。
*如果梭芯线排列不齐，可以通过松开过线架
螺丝钉④及移动绕线摆杆②位置进行调节。
*绕线量由满线跳板上的满线度调节螺钉③加
以调节。注意:适当的绕线量为平行绕线至梭
芯外径的 80%。
1. Turn the power on;
2. Place the bobbin onto the bobbin winder shaft 1;
3. Wind the thread several circles around the bobbin in the direction indicated by arrow;
4. Push down the bobbin presser arm2;
5. Lift the presser foot;
6. Depress the treadle, the winding operation will start;
7. Once finished, the bobbin presser arm 2 will recover automatically.
*If the thread winding is not neat and even, loosen the screw 4 to adjust the position of bobbin winder base.
*Turn the screw 3 to adjust the bobbin winding amount.
Tighten the screw to increase the winding amount.
Loosen the screw to increase the winding amount;
Note: The proper winding amount should be around 80% of the bobbin capacity.
11.针距、倒顺送料（图 11）/ Needle pitch, reverse feed（Fig 11）
针距的长短，可以用转动针距标盘（A）来
调节。逆时针转动时针距调长；顺时针转动时针
距调短。针距标盘（A）的平面（B）上的数字表
示针距长短尺寸（单位为毫米）。注：调节针距
时，要把针距按键（D）往里按压，调整好后放
手复位。
需要倒向送料时，可以将倒缝操纵杆 （C）
向下揿压，即能进行倒缝，手放松后，倒缝操纵
杆（C）自动复位，恢复顺向送料。
The length of the stitch length can be adjusted by
turning the stitch length dial (A).Inverse turn the
clockwise to make the pitch longer; turn clockwise
to make the pitch shorter. The number on the
plane (B) of the stitch length dial (A) indicates the length of the stitch length (in millimeters). Note: When adjusting
the stitch length, press the stitch length button (D) inward and let it reset after adjustment.
When reverse feeding is needed, you can press the reverse stitching lever (C) downward to start reverse
stitching. After the hand is released, the reverse stitching lever (C) will automatically reset to resume forward
feeding.
