. CAUTIONS BEFORE OPERATION
Following items have to be checked every working day before the operation of the machine
and before the start of work hours.
1. Ascertain that the sewing machine is lled with the predetermined amount of oil.
2. Never operate the machine unless the lubricating part in the hook has been lled up with oil.
3. Ascertain that the pressure gauge indicates the designated air pressure of 0.5 MPa.
*
(This is necessary particularly when the compressor is stopped for a lunch break or the like.)
If the compressed air pressure is equal to or less than the designated value, troubles such
as interference between the parts can occur. It is therefore necessary to carefully check the compressed air pressure.
4.
Check whether the needle thread/bobbin thread need to be replenished.
5. To perform sewing immediately after turning ON the power switch, perform trial stitching rst, then proceed with sewing of actual products after the test sewing.
6.
In order to prevent the optical ber sensor of the bobbin thread remaining amount detecting
device from showing a detecting failure, be sure to clean thread waste around the hook using an air gun once or more times a day.
7.
In order to protect the ap sensor from showing a detecting failure, be sure to clean dust on
the reecting tapes of the folding plate and the left ap base using an air gun once or more
times a day.

5. CONNECTING THE POWER PLUG

CAUTION
To prevent possible accidents caused by leakage or dielectric strength, an appropriate power plug shall be installed by a person who has an expert knowledge of electricity. Be sure to connect the power plug to the receptacle that is well grounded.
:
Connection of the power plug to the power depends on the specications of the product. Adjust the
power plug to the power specications to connect.
In case of the product of single-phase, 200 to 240V specications :

Connect the red, white and black wires of the power cord to the power terminal (AC200 to 240V)
and the yellow/green wire to the ground (earth) terminal respectively.
In case of the product with the optional high voltage transformer (with SA-128) :
3
Connect the black wires (3 pieces) of the power cord to the power terminal (AC380 to 415V) and
the yellow/green wire to the ground (earth) terminal respectively.
It is possible to connect to 380/400/415V by setting of the input tap of transformer (standard setting
at the time of delivery : 380V).
This product performs operation by the single-phase connection for 3-phasse 380/400/415V.
[Caution when changing the power source of the high voltage optional transformer]
When using high voltage optional transformer

12. LUBRICATING THE OIL TANK

CAUTION
1. To prevent accidents caused by abrupt start of the sewing machine, do not connect the power plug until lubrication has been completed.
2. To prevent inammation or rash, immediately wash the part when oil has stuck to your eyes or body.
3. If oil has been swallowed, diarrhea or vomiting may occur. Put oil to the place where children
cannot reach.
:
Fill the oil tank with the oil for hook lubrication
before operating the sewing machine.
Remove oil cap 1 and ll the oil tank

− 10 −
• At the time of initial lling, ll the oil
tank with oil of 200cc as the standard
and conrm that the oil amount
indicating rod is working.
• When operating a newly installed machine or a machine which has not
been used for a relatively long period of time, make the machine run at 2,000 sti/min or less for the purpose of break-in. In addition, use the machine
after applying oil to races A of the right/left hooks.
• For the oil for hook, purchase JUKI
MACHINE OIL No. 1 (Part No. : MDFRX1600C0).
• Be sure to ll the oil tank with clean
oil.
• Never ll the oil tank with dirty oil.

13. INSTALLING SA-120 (INTERLINING SUPPLYING DEVICE) (OPTIONAL PART NO. : 40045772)

1. If you want to wind a bobbin, start winding it from recess 5 as illustrated in the gure above. If
you start to wind a bobbin from portion 6, the detection of run-out of bobbin thread will fail to
be performed normally.
2. To ensure the appropriate remaining amount of bobbin thread, it is important to wind the bobbin
uniformly. Be sure to check that the bobbin is uniformly wound particularly at the start of
bobbin winding.
If the bobbin fails to be uniformly wound with thread, properly adjust the lateral position of
tension post socket 3.
3. It is most suitable to wind the bobbin with thread to approximately 80% of the outer diameter of
the bobbin. The winding amount can be adjusted with winding amount adjustment screw 2.
4. Do not press lever 1 except when winding bobbin thread. Motor continues to run and trouble
will be caused.
5. When abnormalities such as overload of the thread winding motor, etc. are delected, thermal
switch 9 is shut off. When thermal switch is shut off, turn ON thermal switch 9 again after
turning OFF it to return.

Precautions to be taken when handling USB devices
1
• Do not leave the USB device or USB cable connected to the USB port while the sewing machine is in opera-
tion. The machine vibration can damage the port section resulting in loss of data stored on the USB device or
breakage of the USB device or sewing machine.
•
Do not insert/remove a USB device during reading/writing a program or sewing data.
It may cause data breakage or malfunction.
• When the storage space of a USB device is partitioned, only one partition is accessible.
• Some type of the USB device may not be properly recognized by this sewing machine.
• JUKI does not compensate for loss of data stored on the USB device caused by using it with this sewing ma-
chine.
• When the panel displays the communication screen or pattern data list, the USB drive is not recognized even
if you insert a medium into the slot.
• For USB devices and media such as CF cards, only one device/medium should be basically connected/in-
serted to/into the sewing machine. When two or more devices/media are connected/inserted, the machine will
only recognize one of them. Refer to the USB specications.
• Insert the USB connector into the USB terminal on the IP panel until it will go no further.
•
Do not turn the power OFF while the data on the USB ash drive is being accessed.

access to that medium will be given the highest priority. (Example: If a medium is in-
serted into the media slot even when the USB memory has already been connected
to the USB port, the medium will be accessed.)
• Restriction on connection
_
Max. 10 devices (When the number of storage devices connected to the sewing
machine has exceeded the maximum number, the 11th storage device and beyond
will not be recognized unless they are once disconnected and re-connected. )
