Loosen adjusting (1) nut and turn adjusting screw(2) to adjust the

presser foot pressure . It should be as light as possible , yet be suffient to

obtain the proper stitch for mation .

线状态的调节

线状态的调节是用针线状态螺帽①，上装饰线状态螺帽②，下
针状态螺帽③来进行调节。

Thread tension

差动比的调节

差动比是通过松开螺钉①后，把螺钉①上下移动来进行调节的。调
节后拧紧螺钉①。

Adjusting the diff. feed ratio

Loosen nut(1)and move the lever up(2) and down to obtain the correct

differential feed ratio.then tighten nut (1).

针脚长度的调节

摁住针距调节按钮，旋转手轮，针距调节按钮会陷进更深
