运用于多种面料   Adaptable for versatile materials 旋梭轴肩、梭尖以及旋梭套的形状有所改变；采用了一种新的挑线装置。这些改进使线的传送更流畅，并可以缝纫出线张力较低，外形美观的钮孔。 A new take-up device is adopted to re-shape the rotating hook shaft,the hook point and the bobbin case.The inprovements contribute to smooth movement of threads and buttonholes are sewn in attractive appearance with lower thread tension.
精确的缝纫进线量 Accurate Sewing Start 可方便的调节面线的进线量，以适应各种不同的布料，因此可在缝纫启动时精确的调整线量。 Feed amount of needle thread can be adjusted to fit in with materials to be sewn.Thus,stitches can always be accurately made when sewing starts.	可适用于多种类型的缝纫线 Adaptable for different Sewing Threads 不同的穿线方法可以适用于各种缝纫线，因此总是可以获得最好的线迹。   Different ways of threading apply to different sewing threads.Thus.best possible stitches can always be acquired.

不会污染工件

No Stains on Workpieces

采用活塞泵为上轮、针杆和挑线杆提供润滑 Piston pump to feed machine oil to the top shaft,the needle and the thread lever. 采用了一种活塞泵的设计。这种方法可以准确地将油箱油毡中的机油输送到上轴、针杆和挑线装置，这样增加了缝纫机的耐久度。活塞泵还可将多余的机油抽回，因此可防止布料受到污染。   A piston pump is designed to feed machine oil in the oil absorbent felt of the oil pan to the top shaft,the needle bar the thread lever.In this way,the service life of the machine is prolonged.The piston pump can draw back excessive oil to prevent stains on materials.

空吸式旋梭润滑   Automatic Lubrication of Rotary Hook   采用了一种油线式润滑的设计。这样不仅增加了旋梭的耐久度，而且也稳定了旋梭的移动，因此缝纫的质量也得到了提高，也不会污染布料。    Lubrication by oil braid is designed to increase durability of the rotary hook and simultaneously stabilize its movement,thus sewing quality is improved without stains on materials.

压脚高度最大为13mm

Maximum Lift Clearance to 13mm for the presser Foot

压脚最大可以上升到13mm，因此可以方便的缝纫大而厚重的布料；比如针织衣物和大衣。 The presser foot lifts as high as 13mm,so that heavy-weight materials can pass under,e.g.,knitwear and coats.	装有同时切断面线和底线的可靠切线机构。 Reliable Mechanism to Trim Needle Thread and Bobbin Thread in the Meantime
切线位于针杆下侧易于操作，并可处理不同面料。 The Mechanism Under the Needle Bar Easy to Operate and Handle Different materials	缝制长度和针数可以方便的进行调节。 Conveniently Regulate Sewing Length and Number of Stitches

方便的设置和调节

Convenient Regulation

钮孔尺寸设置 Regulation Sizes of Buttonholes 钮孔宽度、钮扣参照线和打结宽度可通过螺丝刀设定，不需要打开机器进行调整。   The screwdriver regulates width of buttonholes,recommended threads for buttons and bar tacking width without the machine cover dismounted.	机针和旋梭的位置调节   Positioning Regulation for the Machine Needle and the Rotary Hook   附件中的位置规可以快速准确的调节机针和旋梭的位置。   The positioning block can regulate positions of the machine needle and the rotary book.
