For your perfect operation and safety, before using your new machine, please
read this instruction manual.
YSC-8361 controller is used for an industrial sewing machine. With industrial
sewing machine, it is normal to carry out work while positioned directly in
front of moving parts such as the needle and thread take-up, and
consequently there is always a danger of injury that can be caused by these
parts. So when you ready to operate the machine, please follow the
instructions from trained personnel and instructors regarding safe and
correct operation.
1. NOTICE
1.1 Work environment
▲Please use 220V AC in ±10% ranges.
▲To avoid the false operate; please keep the product away from the high
electromagnetic interference.
▲Please operate in the area which temperature is 5 ℃~45 ℃and
humidity is 80% or less.
1.2 Notice of installation
▲Turn off the power and unplug the cord before installation.
▲The cables must not set to be near the wheel and other movable parts.
▲To avoid the static interference and current leakage, all grounding must
be done.
1.3 Notice of safety
▲Turn off the power before maintenance and repairs or raising the
machine arms, or changing needle, or threading needle.
▲Please don’t open the box except the professional.
▲When turn on the machine in the first time, use low speed to operate and
check the correct rotation direction.
▲During machine operation, don’t touch any moving parts.
▲All moving parts must use the protective device to avoid the body contact
and objects insertion.
▲When there is water or other liquid, or caustic material on box or motor,
you must stop operation and turn off the power.
▲All connector shouldn’t be plug and unplug when power on.
▲The connector should be plug and unplug in the correct method.

Start tacking
Single start tacking, A is the stitches of forward
sewing; B is the stitches of backward sewing.
They are both in range 1~15
Double start tacking, A is the stitches of
forward sewing; B is the stitches of backward
sewing.They are both in range 1~15。
End tacking
Single end tacking, C is the stitches of backward
sewing; D is the stitches of forward sewing.
They are both in range 1~15
Double end tacking, C is the stitches of
backward sewing; D is the stitches of forward
sewing.They are both in range 1~15
Free Sewing
▲As the pedal is stepped forward, the start tacking(if
selected) will be done automatically, then machine will

4
start normal sewing. Once the pedal returned to
balance, machine will stop immediately.
▲As the pedal stepped backward, the end
tacking, trimming and wiping(if selected) will be
done automatically
Constant-Stitch
Sewing
▲Once the pedal is stepped forward, F, G stitches will
be completed with E times.
▲Constant-Stitch Sewing will perform the number of
segments and times as setting, when the stitches are
zero, machine will stop immediately.
Bar-Tacking
Sewing
▲Once the pedal is stepped forward, all the seams of
bar tacking, A, B, C, D sections will be completed with
E times, and the trimming will be done automatically.
▲The pedal must be returned to balance for next
sewing.

5.5 Lower thread counter
Set A11 to “1” to active the counter.
Enter interface: Press Or Special function interface SN F6(refer to
6.6).
Initial counter: Press , the initial value of the lower thread counter
which was set previously will be shown. Adjust it to a suitable value.
How the counter works：
Display initial value
The counter reduces by 1 for every 10 stitches sewn.
If the counter less than 1, the display area will warn and buzzer sounds
for 3 times. After thread trimming, will not start up again. Press
the warning will disappear and sewing will be possible, the counter
reduces continue.
Press again, the display will return to the initial value
5.6 Production counter
Set A11 to “1” to active the counter.
Enter interface：Special function interface SN F2,refer to 6.2
Data acquisition：In SN F2 interface, press will be into collect
process interface, seven-segment display D displays 『L』, seven-segment
displays E,F,G will display the number of stitches for this process. It records
the number of stitches and the number of trimmer. Press to save

6
the data and return SN F2 interface.
How the Counter works: If sewn the number stitches more than the
number of stitches collected 90%, and the number of trimming times more
than collected, the counter add 1.
Clear Counter: press
