thorized 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. Switch the sewing machine off “O” when making any adjustments in the needle area, such as

15. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
16. Basically, the machine should be disconnected from the electricity supply when not in use.
17. 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.
18. (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”
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 product 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 prod-
uct is marked with the words DOUBLE INSULATION or DOUBLE INSULATED.
The symbol may also be marked on the product.
“SAVE THESE INSTRUCTIONS”

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 ma-
chine 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.
ATTENTION
Indicates the operation, etc. which can cause a possible risk of person-
al injury and/or physical 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 sew-
ing machine with it.
● Be sure to use the sewing machine
in the temperature 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 explana-
tion 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 re-
sulting in an unexpected personal injury.
Other precautions
● Do not put the sewing machine
under the direct sunlight 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 temperature in the interior portion of the sewing machine
can rise or the coating of the power cord can melt, causing re or electrical shock.
● The safety device of the sewing machine will work
to stop the sewing machine in order to prevent the
generation of abnormal heat in the case the sew-
ing machine is continuously engaged in sewing at
a low sewing speed for a long time or it is continu-
ously engaged in sewing for a long time under the
high temperature environment. In this event, Start
and Stop button will not light.
The sewing machine will
return to working condition
after about 10 minutes.
Stop!

Presser foot lifting lever
The knee lifting lever is useful when a guilt is being sewn
and for other projects that require the use of both hands.
With the knee lifting lever, you are able to control the position
of the presser foot without using your hands.
Insert the knee lifting lever so that concave and
convex meet.
Push the lever to right-hand side to lift the presser foot.
The presser foot is lowered when the lever goes back to the
original position.
* Do not touch the knee lifting lever while sewing.
It may cause a deformation of a stitch pattern.
Lifting/lowering of the presser foot
The presser foot is lifted/lowered with the presser foot lifting
lever.
The presser foot can be lifted higher than the ordinary lift
position. This feature is useful when placing a heavy-weight
material on the sewing machine.
1 Lowered position …… Presser foot should be lowered
when sewing.
2 Ordinary lift position …… This position is used for fabric
removal and/or changing the
presser foot.
3 Extra lift position …… This position is used to put heavy
materials underneath the presser
foot.
* Be careful that the presser foot and the needle should
not interfere when the needle is in down position and the
presser foot is raised to the extra lift position.
