3-9. Cautions for the compressed air supply (source of supply air) facility
As large as 90 % of failures in pneumatic equipment (air cylinders, air solenoid valves) are caused by
"contaminated air."
Compressed air contains lots of impurities such as moisture, dust, deteriorated oil and carbon particles.
If such "contaminated air" is used without taking any measures, it can a cause of troubles, inviting reduction in productivity due to mechanical failures and reduced availability.
Be sure to install the standard air supply facility shown below whenever the machine provided with pneumatic equipment is used.
Standard air supply facility to be prepared by the user
Air compressor
After cooler
Auto-drain
Air tank
Main line filter
Auto-drain
Air dryer
Quality of the air supply
When the supply air contains a considerable amount of moisture
Ambient environment
When our machine is installed at a place where the temperature greatly changes in the morning and in the evening from that in the daytime or freeze is like to occur
In the aforementioned cases, be sure to install an air dryer.
Mist separator
When the supply air contains a considerable amount of carbon and dust
(Most troubles in the air solenoid valves are caused by carbon.)
Be sure to install a mist separator.
Standard equipment supplied by JUKI
Filter regulator
Air solenoid valve
Air cylinder
Cautions for main piping
• Be sure to slope main piping by a falling gradient of 1 cm per 1 m in the direction of air flow.
• If the main piping is branched off, the outlet port of the compressed air should be pro vided at the top part of the piping using a tee in order to prevent drain settling inside the piping from flowing out.
• Auto drains should be provided at all lower points or dead ends in order to prevent the drain from settling in those parts.

5-2. Needle thread clamp device
A Stitch failures (slip-off of the needle thread, stitch skipping and needle-thread stains) are prevented during the high-speed start procedure as well as consistent sewing performance is ensured by operating the needle thread clamp device. The needle thread clamp device can be turned ON/OFF with
THREAD CLAMP button A . The thread clamp device cannot be used
for details.)
When the memory switch U035 is placed in “disabled”, the needle thread clamp device will not operate. Every time THREAD CLAMP button A is pressed, the status of the thread clamp device and bird’s nest reducing device is changed over as: Thread clamp device ON - Bird’s nest reducing device ON - Both devices OFF.
Select one of the three different functions that you want to use at the beginning of sewing as shown in the table given below.
The thread clamp device cannot be used simultaneously with the bird’s nest reducing device.
Thread clamp operation at the beginning of sewing
Thread trimming operation at the beginning of sewing
Needle thread clamp device ON
Bird’s nest reducing device ON
Both devices OFF
ON
OFF
OFF
OFF
ON
OFF
When this device is placed in ON, stable sewing performance is ensured at the beginning of sewing and high-speed start is enabled.
When this device is placed in ON, the length of thread remaining on the reverse side of material at the beginning of sewing is reduced.
It becomes the same sewing start as conventionally.
(1) When with thread clamp (motion), use the sewing machine after adjusting the needle thread length at the start of sewing to 40 to 50 mm. When the needle thread length is too long, the needle thread end held with the needle thread clamp may be rolled in the seams.
40 to 50mm
In case of with the needle thread clamp, the standard of the length of needle thread is 40 to 50 mm.
• To prevent the thread from slipping off from the needle eyelet at the beginning of sewing or to prevent stitch skipping from the first stitch
→ Adjust the length of needle thread longer within the range.
• To prevent stitch skipping within the second to tenth stitches from the beginning of sewing
→ Adjust the length of needle thread shorter within the range
(2) When you use the thread clamp, set the thread tension at the beginning of sewing to approximately
20. If the thread tension is excessively low, the thread will flap significantly, causing thread tangling.
If it is excessively high, on the other hand, the thread will slip off the needle eyelet and the thread clamp will fail to work. The thread tension at the beginning of sewing, up to the third stitch, can be set with the memory switches U019 to U024.
– 26 –
5-3. Bird’s nest reducing device
When the bird’s nest reducing device is used, the needle thread is trimmed at the beginning of sewing.
As a result, the needle thread that remains on the reverse side of material is shortened, thereby reducing the formation of so-called bird’s nest (thread tangling) to contribute neater finish of the reverse side of material. The trimmed thread is blown out from the righthand side by the air blower to be collected in the cloth chip bag.
40 to 50mm
(1) In the case the bird’s nest reducing device is turned ON, it is necessary to adjust the needle thread length remaining at the needle at the beginning of sewing to 40 to 50 mm as in the case of operating the thread clamp device. If the aforementioned needle thread length is too long, the trimmed thread may be entangled in the hook, causing the sewing machine to be locked. On the other hand, if the aforementioned needle thread length is too short, the trimmed thread (thread waste) cannot be collected but drop on the floor.
(2) Empty the cloth chip collection bag on a regular basis.
1. mediate presser presses the needle thread (as shown in the figure given below), only the bobbin thread will be trim and the sewing machine will fail to produce stitches at the beginning of next sewing. As a result, the sewing machine cannot perform sewing at the beginning of sewing. Enable / disable of the wiper can be changed over with the memory switch U051.
2. In the case the bird’s nest reducing device is disabled with the memory switch U035, or in the case the shorter-thread remaining type is selected with the memory switch
U322, the bird’s nest reducing operation cannot be selected. Refer to
"III-1-6. The moving knife and counter knife (Shorter-thread remaining type)" p.138
for the short er-thread remaining type model.
If the thread tension is excessive ly low at the beginning of sewing, the length of needle thread to be trimmed will be too long. In such a case, the trimmed thread cannot be blown out by the air blower, but will be liable to remain inside the hook.
The thread tension to be applied to the thread when sewing three stitch es (at the maximum) at the beginning of sewing can be set with the memory switches U019 to U024. Refer to
"II-2-6-2. Memory switch" p.78
.

A
B
< U345 Bobbin changing method selection screen >
A : Auto
The number of stitches to be sewn before changing the bobbin is automatically selected from read-in patterns and the preset bobbin-thread winding lengths. In addition, the number of stitches to be sewn before changing the bobbin is automatically updated according to the remaining-thread allowance length at the time of changing the bobbin. In the case the "auto" is selected, the updated number of stitches will be returned to the initial value by carrying out one of the following operations.
・ In the case of reading in a pattern on the AW operation screen
・ In the case the bobbin change is carried out on the AW operation screen
・ In the case the bobbin is taken out on the AW operation screen
・ In the case the bobbin thread winding length is changed on the AW setting screen
・ In the case of changing the AW number-of-stitches input mode from "manual" to "auto"
1. If the remaining-thread allowance length setting does not match the sewing condi tions, the bobbin thread may run out during sewing.
2. If the remaining-thread allowance length is set to a small value, the bobbin thread may run out due to changes in bobbin-thread consumption.
It is therefore necessary to check the actual remaining-thread length before chang ing the set value.
3. If the remaining-thread allowance length is 3.5 m, some waiting time can occur according to the swing conditions such as the thread count, bobbin-thread winding length and sewing pattern. In such a case, check the actual remaining thread length and re-set it.
4. If the bobbin thread tension of two bobbins differs, the remaining-thread length will also differ. It is necessary, therefore, to adjust so that the bobbin thread tensions of two bobbins are equal.
5. Automatic update of the preset number of stitches is carried out from the fourth au tomatic change of bobbin.
6. Under the trial stitching mode, the preset number of stitches is not automatically updated. In addition, note that the preset number of stitches is initialized after the completion of trial stitching.
B : Manual
Bobbin is changed according to the number of stitches to be sewn before changing the bobbin.

Thread unraveling strength can be set in five different stages as 1 to 5 on the thread unraveling strength setting screen. If "0" is entered for the thread unraveling strength, thread unraveling will not be carried out.
Bonded thread (such as coating thread) that is hardened with resin cannot be smoothly tangled on a bobbin. In such a case, enable the thread raveling function to ravel the thread end.
For the thread raveling operation, the reference set value of the raveling strength is "1". The thread raveling operation is carried out in repetition according to the set value. The larger the set value becomes, the more times the thread raveling operation is repeated.
1. Since a long time is required to carry out the thread raveling operation, the set value should be minimized as long as the thread is allowed to wind on the bobbin. If this set value is large, bobbin winding will require a long time to disable sewing until the bob bin changing is completed.
2. Do not use the thread raveling operation in any case other than using bonded thread
(coating thread). If this operation is enabled when using any other thread, the thread will fluff and be entangled on the bobbin. In such a case, the thread remaining on the bobbin may not be totally removed.

In this case, the steps of procedure to be taken up to step 2) are same with those in the case of (1). From step 3), take the following steps of procedure.
3) Place the first bobbin in the bobbin setting section. (Refer to
5-2. How to fit a bobbin in the bobbin case” p.21
for the bobbin setting procedure.)
In the case the bobbin you have just put on the bobbin setting section of the AW-3 device is:
・ an empty bobbin, press A on the bobbin check screen.
・ the bobbin that has already been wound with thread, press
B on the bobbin check screen.
The bobbin is placed in the hook.
4) Subsequently, place the second bobbin in the bobbin setting section.
5) As with 3) described above, if the bobbin you have put on the bobbin setting section of the AW-3 device is:
・ an empty bobbin, press A on the bobbin check screen.
・ the bobbin that has already been wound with thread, press
B
The bobbin is placed in the hook.
6) Press E on the AW operation screen to return to the data
E input screen. Press D to display the sewing screen.
Once the sewing screen is displayed, sewing can be started.
<AW operation screen>
If one of the bobbins is empty, the device winds thread on the bobbin. After the device completes winding of the bobbin, it enters the standby state waiting for the moment to change the bobbin.
Special care should be taken when using a bobbin that has been already wound with thread, since the preset number of stitches may not be sewn in its en tirety (i.e, bobbin thread may run out during sewing) if the quantity of thread wound on the bobbin is not sufficient.
It is recommended to avoid the use of bobbin which has been used halfway or the bobbin wound with unknown quantity of thread (or to use such a bobbin after removing the thread wound on it by hand until it becomes empty) in order to totally prevent the aforementioned problem. If it is necessary to use the bobbin which has been used halfway, it is necessary to set the number of stitches to a smaller value. The quantity of thread to be removed from a bobbin is large initially, but it will become more and more adequate if the
"auto" is selected.
– 112 –
2-11-3. In other case
A
<AW operation screen>
(In the case one or two bobbins are loaded in the device (including the hook) other than the case (2).)
1) Turn the power to the device.
2) If a bobbin is loaded in the bobbin setting section, take it out.
3) If any other bobbin still remains in the device (or in the hook), press A to make the bobbin setting section to feed the bobbin to a position at which the bobbin can be taken out.
Then, carry out the operation procedure (1) or (2).
Be sure to carry the bobbin to the bobbin setting sec tion with A before removing the bobbin which is placed in the hook where nec essary. If you attempt to remove the bobbin directly from the hook, the sewing machine may operate while no bobbin is placed in the hook.
2-11-4. In the case the device remains in the finished state of previous sewing
(In the case the previous sewing has been normally finished, and one bobbin is placed in the hook and the other bobbin is placed in the bobbin setting section.)
1) Turn the power to the device.
2) Press A to display the sewing screen. Once the sewing screen is displayed, sewing can be started.
A
<Data input screen>
In other words, the operation required in the aforementioned state is only to turn ON the power to the device. Note that the number of stitches is set at the value that is effective at the end of previous sewing. So, sewing can be started continuously from the previous sewing.
– 113 –
2-12. Turning OFF of the power
Do not turn OFF the power to the device in the following cases unless there is an emergency.
❶
Device movement:
① While the device is engaged in the removal of thread remaining on the bobbin

Trouble
8. Uneven length of the needle thread
9. The knotting section of bobbin thread at 2nd stitch at the sewing start appears on the right side.
10. Wiper fails to work. (Return is defective.)
Cause
① The tension of thread take-up spring is too low.
② The thread trimmer fails to trim the thread at the correct timing.
③ Loop spreading fault of the moving knife (Needle thread chip remains near the hook)
① Idling of bobbin is large.
② The bobbin thread tension is too low.
③ The needle thread tension at 1st stitch is too high.
Corrective measures
○ Increase the tension of the thread takeup spring.
○ Adjust the position of the moving knife and counter knife correctly.
○ Adjust the initial position of the moving knife correctly.
○ A just the position of the moving knife.
○ Increase the bobbin thread tension.
○ Decrease the needle thread tension at
1st stitch.
11. Thread trimmed at the beginning of sewing is not collected.
12. Thread trimmed at the beginning of sewing is entangled.
① Needle entry of the last needle is the same as that of the sewing start, and the resistance of thread and cloth is large.
① Thread waste accumulates near the thread trimmer connecting bar.
② Trimmed thread is caught between the shuttle race and the counter knife.
③ Length of needle thread remaining at the needle is too short. The thread untwists and separates into single yarns.
① The thread is not trimmed completely to leave a single yarn.
The remaining single yarn is entangled.
○ Shift the needle entry point of the last needle.
○ Defective air pressure setting may be the cause of trouble. Set the air pressure to the optimum value (0.2 - 0.3 MPa).
○ Adjust the position of shuttle race.
○ Adjust the length of needle thread remaining at the needle to the optimum value (40 mm to 50 mm)
○ Change the knife or the throat plate asm. with an appropriate one.
○ Faulty thread trimming may be the
cause. (Refer to "4. Threads are not trimmed." .)
