5. Adjusting the bobbin thread tension
6. Installation of bobbin case
1) Lift up and hold bobbin case latch lever between
two ngers.
2) Push the bobbin case into the hook so that it is
supported by the hook shaft and then snap in
the latch lever.
Press the bobbin case until the predetermined
position is reached, and it will click.
1. If the bobbin case is out of the pre-
determined position, it can jump out
from the hook to cause the needle
thread to tangle on the hook shaft.
Check to be sure that the bobbin
case is properly installed in the cor-
rect position.
2. There is a difference in the shape of
bobbin case between the standard
hook and the dry one. They have
nothing in common with each other.
Adjust the bobbin thread tension as given below when the bobbin thread is pulled up at the position where
thread slit of bobbin case comes up.
WARNING :
To protect against possible personal injury due to abrupt start of the machine, be sure to start the fol-
lowing work after turning the power off and ascertaining that the motor is at rest.
Turning tension adjust screw clockwise will increase bobbin thread tension, and turning it counterclock-
wise will decrease the tension.
Adjust the bobbin thread tension to lower for synthetic lament thread, and to higher for spun thread. The
thread tension is higher by approximately 0.05N when the bobbin case is set to the hook since idle-pre-
vention spring is provided.
When bobbin thread tension is adjusted, check the needle thread tension setting of the
memory switch. (Refer to "V-22. Memory switch data list" p.55.)
Purl stitch 0.05 to 0.15N To such an extent that bobbin case quietly comes down when holding
thread end coming from bobbin case and shaking it quietly up and down.
Whip stitch 0.15 to 0.3N To such an extent that bobbin case barely comes down when holding
thread end coming from bobbin case and shaking it somewhat strongly.

Name of data Extension Description of data
Parameter data LBH00 XXX . EPD
Unique LBH sewing data form such as stitch
shape, cloth trimming length and overedging
width created with the sewing machine.
Vector form data VD00 XXX .VDT
Data on needle entry points created with
the PM-1. The data form is commonly used
among JUKI sewing machine.
27. Communication
* Refer to the Engineer's Manual for how to set the vector form data.
In the case the vector-format data is taken out from the operation panel and saved in a USB thumb
drive or a tablet, and again returned to the operation panel, the set values of scale, sewing speed,
etc. will be returned to their reference values. It is therefore necessary to check the set values before
starting sewing. In addition, if multiple pieces of vector-format data are used for continuous sewing
or cycle sewing, those data cannot be read with a tablet.

Precautions to be taken when handling USB devices
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(TM) cards, only one device/medium should be basically connected/
inserted 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.
