11. Relation between the rocking thread take-up timing and the needle thread loop /
摆动挑线杆的同步和线环的关系
In case stitch skipping or thread breakage occurs due
to excessive large or small needle thread loop even
when performing threading in case of using stretchable
threads or less stretchable threads described in "Standard
threading", change the needle thread drawing timing of the
rocking thread take-up and adjust the size of needle thread
loop.
1) Loosen screw 1.
2) Move 2forward or backward. The relation between
the moving direction and the size of needle thread loop
is as shown in the table below.
3) After the adjustment, securely tighten screw 1.
* Clearance between crank 2and thrust collar 3has
been factory-adjusted to 4 mm at the time of delivery.
(Engraved marker line on rocking thread take-up shaft
4aligns with the edge of crank 2.)
Position of crank 2 Move forward Move backward
In case of threading
for standard seams
Loop becomes
smaller.
Loop becomes
larger.
In case of threading
for soft seams
Loop becomes
larger.
Loop becomes
smaller.
Note : The adjusting direction becomes reverse by way of
threading. So, be careful.
1. When screw 1is loosened, the rocking thread take-up rotates due to the light weight. So, be careful. If
it rotates, refer to the item “Adjusting the rocking thread take-up”.
2. Do not change the timing other than the aforementioned one since the sewing trouble will be caused.

2. Oiling / 关于加油
〈初次使用缝纫机时〉
出货时，机油均被排放。因此初次使用缝纫机之前，请一定加入机油。
· 使用机油 : JUKI MACHINE OIL 18
加油时，请卸下标有「OIL」的加油口盖子 2，把机油加到油尺 1的上下刻线之间。
〈使用缝纫机前的检查〉
1） 请用检查油尺 1，确认油量是否在上下 2 条刻线之间。如果油量比下线还低时，请补加机油。
2） 转动缝纫机，请从机油循环确认窗 3确认是否机油从喷嘴喷出来。如果没有机油喷出时，请进行「滤油器的检查、
更换」（参照 28 页）。
机油添加剂会造成机油的劣化或造成缝纫机的故障，因此请不要使用。
Remove oil hole cap 2onwhich“OIL”isindicatedandll
the oil reservoir with lubricating oil up to the level between
the upper and lower engraved marker lines.
<Checking before using the sewing machine>
1) Check oil gauge 1and make sure that lubricating oil
level is between the upper and lower two lines. When
lubricating oil level lowers below the lower line, supply
lubricating oil.
2) Make sure that lubricating oil comes out from the
nozzleofoilcirculationidenticationwindow3when
rotating the sewing machine. When lubricating oil does
not come out, perform “Inspecting and replacing the oil
lter”.(Seepage28.)
<Whenusingthesewingmachineforthersttime>
Lubricating oil has been taken out at the time of delivery.
Be sure to supply lubricating oil before using the sewing
machineforthersttime.
• Oil used : JUKI MACHINE OIL 18
Do not use oil addition agent since
deterioration of lubricating oil or machine
trouble will be caused.
1. Lubricating oil / 关于机油
The mechanisms inside the frame such as the needle
bar, presser lift and spreader components are lubri-
cated with grease. Never add oil inside the frame.
If inside of the frame is oiled, the grease will
be expelled, resulting in mechanical failure.
NO OILING
严禁加油 针杆、压脚提升以及分布器等有关零部件全部采用润滑
脂润滑结构。因此，请不要向里面加油。
加油之后，会使润滑脂流失，因而造成机器故
障。
3. Replacing the lubricating oil / 缝纫机油的更换
WARNING :
To protect against possible personal injury due to abrupt start of the machine, be sure to start the
following work after turning the power off and ascertaining that the motor is at rest.
注意 :
为了防止突然起动造成人身事故，请关掉电源，确认马达确实停止转动后再进行操作。
