(1) Manually so to raise the needle (In case of double curvilinear stitches, the needle is referred to the one on the right side, The same below) by 2.2mm from fht lower limit, when the point of rotating shuttle would be at the central line of the needle. (See Figure 20)
(2) If necessary, loosen the set screw on the rotating shuttle, the point of which should be aligned with the central line of the needle. At the moment, the space between the notch of needle and the rotating shuttle is about 0.05-0.1mm (see Figure 21).
3. Height of the needle staff
(1) Set the width of swaying needle to the maximum and turn the belt pulley toward the operator manually to make the needle stand at the left position and the shuttle point at the centre of the needle. At the moment the length from the needle hole till the shuttle point should be 0-0.5mm (see Figure 22)
(2) If the height of needle staff is not in the correct position, it is necessary to remove the panel, release the connecting screw on the needle staff, and then raise or lower the staff to the standard height. After that, re-tighten the screw.
4. Mounting and Dismounting of Rotating shuttle (see Figure 23)
To start with, raise the needle staff to the maximum before removing the rotating shuttle, then remove needle plate, needle and the case of shuttle core, meanwhile take down the screw 1 on the locating hook for the rotating shuttle and the locating hook 3 itself; release the three screws 2 on the shuttle, which is capable of rotating freely along the driving spindle, Turn the upper wheel manually to make the feeding rack go upward. Af this point, turn the rotating shuttle manually to allow the feeding rack passing by the position to be touched and then remove it.
The mounting or shuttle is done in an inverted order with the process of dismounting.

八、几种缝纫方法和附件的使用
1、直缝：
采用专用的直缝压脚、针板与送料牙(图二十四)比采用多功能压脚、针板与送料牙进行直
缝，效果会更佳，适用范围会更广。
进行直缝时，横针距必须调至0，采用直缝锁紧装置锁紧针杆摆动架，并换上专用压脚、针
板、送料牙。更换送料牙时(图二十五)，先卸下针板和针板内盖板，把推板往外拉，松开二只螺
钉，卸下多功能送料牙，换上专用送料牙。
图二十四 Figure 24
图二十五 Figure 25
2、刺绣：
刺绣前的准备工作：
① 必需使横针距在0~12mm之间任意调
节，把直针距调至0位,并调整膝控部件(见图
三),使件2控制3运动,则膝部可以控制机针
的摆动。
② 卸下压脚、针板、针板内盖板、推板和
送料牙,换上绣花板;
③ 用左手捏紧面线线头,用手朝自己方向
转动带轮,使底线从针孔中拉出;
④ 确保内外棚格将缝料绷紧,否则引起跳
针,断线及缝料萎缩(如图二十六)。
3、拉链缝:
这种缝法采用拉链压脚(图二十七),便于
针迹接近突出的边,并旋松螺钉B,调节压
脚,使机针位于压脚的左、右边槽A,可适用
于图二十八中几种情况等。
4、卷边缝
卷边缝采用卷边压脚(图二十九)
拆掉多功能压脚,换上卷边压脚,采用直
缝法,针位选择中间,就可以进行如图三十的
卷边缝。
5、包梗缝:
进行包梗缝时,更换上专用的包梗压脚、
针板、送米牙(图三十一),针位选择中间,横
针距调节至3mm之内,把一条较粗的线穿过包
梗压脚的小槽A,就可以进行包梗缝。(图三十
二)
6、装饰缝:
只要变换左、中、右的针位,及熟练控制
横针距,就可以缝出如图三十三的图案。
7、其它一些实用缝法(见图三十四)。

VIII. MODES OF SEWING AND APPLICATION OF ACCESSORIES
1.Linear Sewing
In case of linear sewing, the best effect and wider scope of application will be achieved if by
aboption of the special linear presser foot, needle plate and material-feeding tooth(see Figure 24)
rather than the multi-functional ones.
During linear sewing, the horizontal needle distance should be set to O position, and the linear
locking unit with swaying rack of looking needle shaft can be used in combination with special
presser foot, needle plate and material-feeding tooth. To replace material-feeding tooth, firstly re-
move needle plate and its inner cover, then push the thrust plate outward, release two screws,
and replace the multi-functional material-feeding tooth with the special one.
2.Embroidery
Preparation before embroidering
(1) It should be noted that and free regulation can be made at the horizontal needle distance
between 0~12mm. Set the vertical needle distance to O position and will adjust the knee-control
parts (see Figure 3) to make the component 2 control the movement of the component 3. As a
result, the "knee" can be predicted to control the swaying of the needle;
(2) Remove the presser foot, needle plate, inner cover, thrust plate and material-feeding tooth.
After that, the embroidering plate is put into use;
(3) Hold firmly the end of the surface stitches with your left hand, turn the belt pulley manual-
ly toward the operator, and then makes the bottom stitches pull out from the holes of the needle
plate;
(4) Make sure to stretch tightly the material between the internal and external embroidering
frame. Otherwise, skipping, stitches-breaking or material creased might be found (see Figure 26).
3. Zippered Sewing
This mode is preferable to make use of zippered presser foot (see Figure 27) in a bid to
make the stitches more accessible to the projecting stitches. Then release the screw B, regulate
the presser foot and set the needle to the presser foot and set the needle to the left and right
grooves A of the presser foot. This mode is expected to suit for the sewings, seen in the
Figure 28.
4. Hem-wrapping mode
In this mode, the hem-wrapping presser foot can be used as we wish (see Figure 29). Re-
move the multi-functional presser foot and replace it with the hem-wrapping one. This is also a
mode of linear sewing with the needle set to the central position, shown as in the Figure 30, the
hem-wrapping operation can be effected.
5. Stem-wrapping mode
During the sewing with the stem-wrapping mode, the special stem-wrapping presser foot, nee-
dle plate and material-feeding tooth (see Figure 31) should be put into use. The needle is set to
the central position and the horizontal needle distance set to 3mm, and then run the rougher
thread through the small groove A on the stem-wrapping presser foot so that the sewing of this
mode will be smoothly conducted (see Figure 32).
6. Decoration Sewing
If the left, central and right needle positions can be freely changeable and the horizontal nee-
dle distance skillfully controlled, the patterns of the decoration sewing will be well achieved as
seen in the Figure 33.
7. Other modes of practical sewing (see Figure 34)
