plug (A) and the panel on the upper part of the machine
head, fills up the oil sufficiently according to the graphic
position, then installs the upper panel, and raises the
Presser Foot to run1000-1500 needles/min at low speed,
and observes the oil injection situation of the oil
window(B). After lubrication is normal, it still needs to
keep running at low speed for 30 minutes. After testing,
the sewing speed is gradually increased, and after about
one month's use , the machine can fully run and sew. Then
according to the nature of the work, it can be increased to
a certain seam speed. As shown by the arrow in Fig.4, the
solid grease is added every six months in the sleeve of the
lifting shaft, and 1-2 drops of white oil are added every 1-2
days in the front sleeve of the swinging shaft, and the
white oil is wiped clean.

面线采用左捻线，底线则左、右捻均可使用，
缝线捻向的鉴别，可按图十所示把缝线捏住，以右
手按图箭头方向搓转缝线，若线股越搓越紧，则是
左捻线，反之即为右捻线。
请使用 DP×17 型或 135×17 型机针， 机针
的粗细应适合缝料的性质。如用过细的机针缝制紧
厚的织物，机针就容易折断，也会引起跳针、断线
等现象。相反如果用过粗的机针缝制紧密的织物，
则会因针孔太大而损坏织物。所以应根据缝料性质
不同，机针和缝线的粗细都要适当地进行选择。
The upper thread is left-twisted, and the bottom
thread can be twisted left or right. To identify the twisting direction of the suture, you can pinch the suture as
shown in Figure 10 and twist the suture in the direction of the arrow with your right hand. The tighter the twist,
the left twist, and the opposite is the right twist.
Please use DP×17 or 135×17 needles. The thickness of the needle should be suitable for the nature of the
sewing material. If you use a needle that is too thin to sew tight and thick fabrics, the needle will easily break,
and it will also cause skipped stitches and thread breakage. On the contrary, if a thick needle is used to sew tight
fabrics, the fabric will be damaged due to too large needle holes. Therefore, the thickness of the needle and
thread should be appropriately selected according to the nature of the sewing material.

缝线的张力要根据缝料的差别，缝线的粗细
以及其他一些因素变动。
实际使用中，是根据缝纫出来的线迹，来调
整底、面线的张力，使之得到正常的线迹。
底线张力调整，只要用小号螺钉起子旋转梭
心套上梭皮螺钉（A）加大或减小底线压力即可。
一般来说，底线如果用 50＃涤纶线， 梭心
装入梭心套后，拉出缝线穿过梭心套线孔，捏住
线头吊起梭心套， 梭心套则能缓缓下落，就可以
使用。
面线张力以底线张力为基础。面线张力调
整， 主要变换夹线组件中挑线簧张力， 挑线簧
摆动幅度， 夹线簧张力及线勾的位置等。
The tension of the suture varies according to
the difference of the sewing material, the thickness
of the suture and other factors.
In actual use, the tension of the bottom and
upper threads is adjusted according to the stitches
sewn out to obtain normal stitches.
To adjust the bobbin thread tension, just use a
small screwdriver to turn the bobbin screw (A) on
the bobbin case to increase or decrease the bobbin thread pressure.
Generally speaking, if 50# polyester thread is used for the bottom thread, after the bobbin is loaded into the
bobbin case, pull out the suture through the bobbin case thread hole, Pinch the end of the thread and lift the
bobbin case, the bobbin case can fall slowly, You can use it.
The upper thread tension is based on the lower thread tension. The upper thread tension adjustment
mainly changes the tension of the thread take-up spring in the thread tension assembly, the swing amplitude of
the thread take-up spring, the tension of the thread tension spring and the position of the thread hook.

挑线簧摆动幅度为 5～8毫米。缝纫簿的缝料
（短针距）则要减弱挑线簧的张力放宽摆动幅
度，缝制特别厚的缝料则反之。
1、挑线簧张力调节
先旋松夹线调节座螺钉（A）, 夹线螺钉
（B）就能转动，顺时针转动时张力增加,反之则
减少，调节好后，仍将夹线调节座螺钉（A）旋
紧。
控制方法：
松开夹线调节座螺钉（A）, 将夹线螺钉
（B），逆时针转动，使挑线簧 C的张力压缩到 0 ,
再把夹线螺钉（B）顺时针转动， 至挑线簧（C）
触及夹线调节止动缺口，然后， 夹线螺钉（B）
再逆时针回转二分之一转动角度即可，最后旋紧
夹线调节螺钉座（A）。
2、挑线簧摆动幅度的调节旋松夹线调节座固
定螺钉（B），转动夹线器（C），调节其摆动幅
度，夹线器（C）顺时针转动，摆动幅度增大，反
之则减少。通常，机器在出厂前，挑线簧均已调
整妥善，只是在缝纫特殊的缝料或特殊的缝线
时，才需要重新进行调整
The swing amplitude of the thread take-up
spring is 5-8 mm. Sewing material for sewing book
(short needle Width), the tension of the thread take-up spring should be weakened to relax the swing range, and
the reverse is the case when sewing particularly thick sewing materials.
1. Thread take-up spring tension adjustment
First loosen the thread tension adjusting seat screw (A), the thread tension screw (B) can be turned, the
tension will increase when turned clockwise, and vice versa, the tension will decrease. After adjustment, still
tighten the thread tension adjusting seat screw (A).
Control Method:
Loosen the thread tension adjusting seat screw (A), turn the thread tension screw (B) counterclockwise to
compress the tension of the thread take-up spring C to 0, and then turn the thread tension screw (B) clockwise to
the thread take-up spring (C) Touch the notch of the thread tension adjustment stop, then, turn the thread tension
screw (B) counterclockwise by half the angle of rotation, and finally tighten the thread tension adjustment screw
seat (A).
2. Adjustment of the swing amplitude of the thread take-up spring. Loosen the fixing screw (B) of the thread
clamp adjusting seat, turn the thread clamp (C) to adjust its swing range, turn the thread clamp (C) clockwise, the
swing amplitude increases, and vice versa. Usually, the thread take-up spring has been adjusted properly before
the machine leaves the factory. It is only necessary to readjust it when sewing special sewing materials or special
sewing threads.

The normal stitches of the sewing machine
should be as shown in Figure a. If the stitches are
abnormal, the sewing material will wrinkle and
thread breakage. The tension of the bottom and
upper threads should be adjusted. Make it reach the
normal stitch.
a. If the upper thread is too tight and the bottom
thread is too loose, turn the thread clamping nut
counterclockwise to relax the pressure on the upper
thread. Or use a small screwdriver to tighten the
bobbin screw to increase the pressure on the bottom
thread.
b. If the upper thread is too loose and the
bottom thread is too tight, turn the thread tension nut clockwise to increase the pressure on the upper thread or
use a small screwdriver to loosen the bobbin screw to reduce the pressure on the bottom thread.
c. If the traces in Figure d and e appear, you can also adjust them by referring to the above method

1、机针位置的调节
用手转动主动轮，使针杆（C）下降至最低位
置，卸下面板（A）上的橡皮塞，旋松针杆（C）
上的针杆接头螺钉（B），上下移动针杆（C），
初步定出同步位置（针杆的同步位置，当针杆下
降至最低位置时，机针线孔的中心（D）应与旋梭
内周面（E）在同一位置上。如图24所示位置）。
旋紧针杆接头螺钉（B），塞上橡皮塞即成。
2、旋梭同步的调节
旋梭和机针之间的相互运动关系，对缝纫性
能的影响很大。标准的同步关系是：用手转动上
轮，使机针向下运动到最低位置后再向上回升2.5
毫米，这时旋梭钩线尖(D)，应与机针的中心线
（C）一致，在此位置时, 钩线（D）应高于机针
线孔（E）上边约1.2毫米。
在调节旋梭的同步关系时，还要注意到旋梭
尖与机针的侧面间隙。机针（D）缺口，底部与旋
梭钩线尖（C）的间隙为0.05毫米
1. Adjustment of needle position
Turn the driving wheel by hand to lower the
needle bar (C) to the lowest position, remove the
rubber plug on the panel (A), loosen the needle bar
connector screw (B) on the needle bar (C), and move
the needle bar (C) up and down. The synchronization
position is initially determined (the synchronization
position of the needle bar. When the needle bar is
lowered to the lowest position, the center (D) of the
needle thread hole should be at the same position as
the inner circumference (E) of the hook. As shown in
Figure 24 Show location). Tighten the needle bar
connector screw (B), and plug the rubber stopper.
2. Adjustment of the hook synchronization:
The mutual movement relationship between
the hook and the needle has a great influence on the
sewing performance. The standard synchronization
relationship is: turn the upper wheel by hand to
make the needle move down to the lowest position
and then rise back up by 2.5 mm. At this time, the
hook thread tip (D) should be consistent with the
needle center line (C) .At this position, the hook
thread (D) should be about 1.2 mm higher than the
upper edge of the needle thread hole (E).
When adjusting the synchronization relationship of the rotary hook, also pay attention to the side clearance
between the tip of the rotary hook and the needle. The needle (D) notch, the clearance between the bottom and
the hook thread tip (C) is 0.05 mm

压脚在提升范围内，夹线器上的夹线板有一
个张开期，挺线的时间可进行调节。调节时，先
卸下机头背面的橡皮擦，用螺丝刀（B）旋松膝控
提升杠杆（左）螺钉（A），这时松线凸轮可以左
右转动，往右移挺线慢，往左移挺线快。
The tension discs should be pushed apart to
open when the presser foot is lifted. But the open
timing of the tension discs can be adjusted as
follows: Remove face plate and the rubber plug at
rear side of arm and loosen screw (A) of the knee
lifting lever (left), then the tension releasing cam can
be moved leftward or rightward when the cam is moved right-ward. It is later to open, otherwise it is earlier to
open.
上、下同步送料是该产品的重要性能之一。
在缝纫过程中，应根据各种缝料的摩擦系数的不
同和缝纫工艺的不同要求，对上送料机构的摆压
脚滑块与摆压脚轴的中心距（L）进行调节。
调节方法：
增大中心距 L——上送料量增大。
减小中心距 L——上送料量减少。
对于某些制品的特殊缝纫要求，如缝件的上
层的送料量要求大于（或小于）下层的送料量，
也可以根据以上原理在一定范围内调节使用。
During the sewing, the center gauge (L)
between the walking foot sliding block and its shaft can be adjusted according to the differences of the friction
coefficients of the friction coefficients of materials and the sewing process.
Method: Increase L -- the upper feed amount enlarged
Reduce L – the upper feed amount shorten
For special sewing requirements, for example, the upper layer of material needs more amount than the lower
layer does, in this case, adjustment can be done in the range of above theory for operation.

根据缝料疏松和结实程度的不同，在缝纫
中，对摆压脚、小压脚的交叉提升量，可在一定
的范围内进行适当的调节。在一般的中厚料缝纫
中，摆压脚提升量为 5.5mm 之内，小压脚提升时
为3.5mm 左右。当其他机构不变的情况下，两压
脚提升量之和基本上是一定值。两提升量的变化
近似于按反比定律变化。即：摆压脚的提升量增
加，则小压脚的提升量就减少。反之也然。
调节方法：旋松偏心轮连杆调节曲柄螺钉
A，按图示向上转动压脚升降前曲柄，摆压脚的提
升量增大，反之，向下转动，小压脚的提升量减
少。但其调节量有一定的范围限调，不宜过大。
调好后，将螺钉拧紧， 用手转动上轮，检查一切
正常后方可使用。
During the sewing, the alternate lift amount can be adjusted according to the nature of material. In general
sewing, the amount of walking foot is 5.5mm,and the presser foot lift amount is 3.5mm.
Method: loosen the screw A. turn presser foot front crank up ward to increase the amount of walking foot.
Turn it downward to reduce the presser foot amount, the range of adjusting amount is not too
在缝纫过程中，要改变摆压脚、小压脚的提
升量，其调节方法是：先将偏心轮连杆螺钉（A）
旋松，然后调节该螺钉与压脚升降轴中心距 B；
如果使摆压脚、小压脚的提升量都增加，则使中
心距 B调小；反之，则可使提升量都减少。其调
节量也有一定的范围，调节幅度不宜过大，调节
好后，将螺钉拧紧，慢慢转动上轮，检查有无碰
撞现象，一切正常后方可使用。
The lift amount of walking presser foot together
with presser foot can also be adjusted slightly. When
adjust-ting, loosen screw (A) adjust its center
distance B between the screw (A) and the presser
foot lift shaft. The lift amount is increased as to
shorten the center distance B, and the lift amount is
decreased as to widen the center distance B. After adjustment, tighten the nut again.

在缝纫过程中，有时用大针距缝纫，有时用小针距缝
纫，在大针距缝纫时，摆压脚前后的行程比较大。反之，
就小了。为了在缝纫过程中，使摆压脚槽的前端与小压脚
后端面不碰撞，且保证有一定的间隙 C（一般取 1.5mm 左
右）。故在小针距缝纫时，需要摆压脚向针杆靠拢点，调节
方法：首先旋松摆压脚前曲柄螺钉，然后向上转动压脚摆
动轴，则摆压脚就向针杆靠拢，调节时，应该注意间隙 C
的定值要求。
In sewing operation, for preventing the walking foot from
striking on presser foot a proper clearance C of approx. 1.5mm
should be maintained between them. When the clearance is
too small or too big, necessary to adjust, loosen rear crank
screw and turn the rock shaft, then the walking foot moves near the needle bar. When adjust, be sure to note the
fixed number of the clearance C.
