“IMPORTANT SAFETY INSTRUCTIONS”
When using an electrical appliance, basic safety precautions should always be followed, including the following: Read all in-
structions before using this sewing machine.
“DANGER ____ To reduce the risk of electric shock:”
1. The appliance should never be left unattended when plugged in.
2. Always unplug this appliance from the electric outlet immediately after using and before cleaning.
“WARNING ____ To reduce the risk of burns, re, electric shock, or injury to persons:”
1. Do not use the appliance as a toy. Caution is advised when the appliance is used by children, or near children. This sew-
ing machine can be used by children aged from 8 years and above and persons with reduced physical, sensory or men-
tal capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of
the sewing machine in a safe way and understand the hazards involved. Children shall not play with the sewing machine.
Cleaning and user maintenance shall not be made by children without supervision.
2. Use this appliance only for its intended use as described in this manual. Use only attachments recommended by the
manufacturer as contained in this manual.
3. Never operate this appliance if it has a damaged cord or plug, if it is not working properly, if it has been dropped or dam-
aged, or dropped into water. Return the appliance to the nearest authorized dealer or service center for examination,
repair, electrical or mechanical adjustment.
4. Never operate the appliance with any air openings blocked. Keep ventilation openings of the sewing machine and foot
control free from the accumulation of lint, dust, and loose cloth.
5. Keep ngers away from all moving parts. Special care is required around the sewing machine needle.
6. Always use the proper stitch plate. The wrong plate can cause the needle to break.
7. Do not use bent needles.
8. Do not pull or push fabric while stitching. It may deect the needle causing it to break.
9. Do not carry out sewing with a marking pin stuck in the material since doing so can cause knife/needle breakage.
In addition, do not attempt to cut anything other than fabric and thread with the upper/lower knives.
10. Switch the sewing machine off “O” when making any adjustments in the needle area, such as threading needle, chang-
ing needle, threading looper, or changing presser foot and the like.
11. Always unplug the machine from the electrical outlet when removing covers, when covers are opened to thread the loop-
ers, when lubricating or when making any other user servicing adjustments mentioned in the instruction manual.
12. Never drop or insert any object into any opening.
13. Do not use outdoors.
14. Do not operate where aerosol (spray) products are being used or where oxygen is being administered.
15. To disconnect, turn all controls to the off “O” position, then remove plug from outlet.
16. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
17. Basically, the machine should be disconnected from the electricity supply when not in use.
18. If the power cord of this appliance is damaged, it must be replaced with a special cord by your nearest authorized dealer
or service center.
19. (Except USA/Canada) This machine is provided with double insulation.
Use only identical replacement parts. See instructions for servicing Double-Insulated machine.
“SERVICING DOUBLE-INSULATED PRODUCTS
(Except USA / Canada)”
In a double-insulated product, two systems of insulation are provided instead of grounding. No grounding means is provided
on a double-insulated product nor should a means for grounding be added to the product. Servicing a double-insulated prod-
uct requires extreme care and knowledge of the system and should only be done by qualied service personnel. Replacement
parts for a double-insulated product must be identical to those parts in the product. A double-insulated product is marked with
the words DOUBLE INSULATION or DOUBLE INSULATED.
The symbol may also be marked on the product.
“SAVE THESE INSTRUCTIONS”
“This overlock sewing machine is intended for household use only.”

Congratulations on your purchase of a JUKI sewing machine.
Please be sure to read safety precautions in “To use the sewing machine safely” in the Instruction Manual before use to
fully understand the functions and operating procedures of the sewing machine so as to use the sewing machine for a
long time.
After you have read the Instruction Manual, please be sure to keep it together with the warranty so that you can read it
whenever necessary.
To use the sewing machine safely
Marks and pictographs included in the Instruction Manual and shown on the sewing machine are used so as to ensure
safe operation of the sewing machine and to prevent possible risk of injury to the user and other people.
Warning marks are used for different purposes as described below.
WARNING Indicates that there is a possible risk of death or serious injury if this mark is ignored
and the sewing machine is used in a wrong manner.
CAUTION
Indicates the operation, etc. which can cause a possible risk of personal injury and/or physi-
cal damage if this mark is ignored and the sewing machine is used in a wrong manner.
Pictographs mean the following:

3
● Do not wipe the sewing machine with solvent such as
thinner.
When the sewing machine
is soiled, put a small quan-
tity of neutral detergent
on a piece of soft cloth
and carefully wipe off the
sewing machine with it.
● Be sure to use the sewing machine in the tempera-
ture range from 5ºC to 40ºC.
If the temperature is excessively low, the machine
can fail to operate normally.
WARNING
For the combination of the material and the thread and needle, in particular, refer to the explanation table in “Replacement
of the needle”.
If the needle or thread does not match the material used such as in the case that an extra heavy-weight material (e.g.,
denim) is sewn with a thin needle (#11 or higher), the needle can break resulting in an unexpected personal injury.
Other precautions
● Do not put the sewing machine under the direct sun-
light or in a humid place.
Be aware that the following state can take place since the sewing machine incorporates semi-conductor electronic
parts and precise electronic circuits.
* The operating temperature of the sewing machine is between 5ºC and 40ºC. Do not use the sewing machine under
the direct sunlight, near the burning things such as a stove and candle, or in a humid place. By so doing, the tempera-
ture in the interior portion of the sewing machine can rise or the coating of the power cord can melt, causing re or
electrical shock.

Handwheel
The handwheel turns forward, i.e. in the same direction as on
a household sewing machine.
手轮
手轮要向前转动，家用缝纫机都是朝一个方向转。
Two step presser foot lifter with
integrated front foot lift
To raise the presser foot, lift the press-
er foot lever on the rear of the ma-
chine, until it engages (A). It can be
raised again to the maximum height
and held in this position to provide
more space between presser foot and
stitch plate (B).
When the foot is raised (A and B), the
front of the foot is automatically lifted.
Note: When the presser foot is raised,
all the tensions are released making it
easier to thread the machine.
压脚扳手的使用方法
通过压脚扳手即可使压脚抬升
通常情况下，压脚扳手抬升至 A 位置
在需要更换压脚或缝制厚料需要压脚与
针板之间释放出更多的空间时，可将压
脚扳手抬升至 B 位置。
注意 ：一旦将扳手抬升至 A 位置时，夹
线片是处于打开状态，因此在穿线时请
务必抬升压脚。
* The needle is brought to its upper end by aligning the
“” marking on the side of the front cover with the “ ”
marking on the handwheel.
*将机罩侧面盖板上的” ”标记对准手轮上的“ “标
记后即可使机针处于最高位。

A are bent.
B are damaged or blunt.
C have hooked points.

Needle and thread
The needle size used depends on the thread. The needles should be in accor-
dance with thread used.
When sewing, the thread is fed through the long groove in the needle. If the
needle is too ne, the thread does not t into the groove and stitches will be
skipped.
Use needles No. 70 - 90.
* It is recommended to use JLx2 needle, especially when sewing thick materi-
als, overlapped section, etc, with overlock machine.
机针和缝线
机针的型号取决于缝线。机针大小应该与缝线粗细相符。
在缝纫时，缝线会穿过机针上的针孔。如果机针太细的话，缝线将无法穿过针
孔或引发跳线。
机针型号为 Mo.70-90。
*推荐使用 JLx2 机针，特别是缝制厚料时，几层叠起的重叠部位以及包缝等
工序时较适宜。
机针
机针必须是完好无损。
机针如果发生如下问题则有可能会引
发故障 ：
A弯曲。
B机针破损或是针尖磨损。
C有毛刺。
