8. ADJUSTMENT OF EACH PART

WARNING : Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine.

(1) Replacing the cloth cutting knife and the knife holder

■ Replacing the upper cloth cutting knife and the knife holder

1) Loosen thumbscrew ① and remove knife holder and cloth cutting knife ②.
2) Make the knife holder or the cloth cutting knife desired to be replaced come in contact with stopper ③ and tighten thumbscrew ①.

Stopper ③ is for positioning. Do not move it.

■ Lower cloth cutting knife and the knife holder

1) Loosen setscrew ③ and remove knife holder and cloth cutting knife ②.
2) Make the knife holder or the cloth cutting knife desired to be changed come in contact with stopper ① and tighten setscrew ③.

Stopper ① is for positioning. Do not loosen screw ④.

When replacing the cloth cutting knife, match the knife No. to the knife No. of the program. Use the cloth cutting knife and the knife holder as a set.

(Two different knife marks are formed and cloth cannot be precisely cut. As a result, breakage of the cloth cutting knife will be caused.)

(2) Adjusting the cloth cutting knife pressure

• The cloth cutting knife pressure and the contact time of the knife and the knife holder can be changed.
• When replacing the cloth cutting knife or the knife holder, or changing the sewing material, it is necessary to adjust the pressing amount of the knife or the stopping time of the knife lower position.
• Perform the change of set value after fully performing checking of the knife holder face and the knife.
• Gradually increase any set value from the small amount while checking the set value.

■ Adjusting the knife pressing amount

1) Pressing [ADJUST] key①, turn ON the power.
2) The pressing amount set in 4-digit LED ⑤ is displayed.
3) Press [READY Ⓞ] key ④ to light up the sewing LED. At this time, the feed base performs origin retrieval.
4) The pressing amount can be set with [RIGHT ⊖] key ② or [RIGHT ⊕] key ③.
The setting range is — 100 to 300. The more the number is, the higher the knife pressure becomes.
5) Lower the presser with the presser switch and press the start switch to actuate the knife.
The pressing amount can be set again using [RIGHT ⊖] key ② or [RIGHT ⊕] key ③ with the presser raised.
6) After setting is completed, press [ADJUST] key ① and the knife adjustment mode will end.

The set value is stored in memory when the knife is actuated by the start switch or [ADJUST] key is pressed. When turning OFF the power without performing either operation, the setting is not stored in memory

Set the knife pressing amount as small as possible in order to protect the knife and the knife holder and maintain the durability. If the knife pressing amount is excessively large, malfunction of the drive motor or breakage of the knife will be caused.

Knife holder Nos. "0" to "9" to which 10 kinds of knife pressing amounts have been set can be set to the pattern data using memory switch No. 40. (Refer to "Setting the pattern data of cloth cutting knife pressing amount", p.44.)

■ Adjusting the stopping time of the knife lower position

The stopping time at the knife lower position can be extended.

Setting of 50 to 500 ms can be performed with the memory switch No. 55.

(Refer to "14. MEMORY SWITCH" P.68.)

Even when the pressing amount is increased, the result is not effective, when the cut length is excessively long or sewing heavy-weight materials, set the stopping time of the knife lower position longer than the specified time.

(3) Worn-out of the knife holder face

Contact face of the knife holder with the cloth cutting knife.

A

B

C

1) Remove the knife holder. (See p.26.)
2) When the knife mark is too deep, the knife mark is duplicate (A of Fig. on the left side) by using another knife or the knife mark is partially formed and not formed on the whole surface (B of Fig. on the left side), grind the face with an oil stone or the like so that the knife mark becomes uniform.

The knife holder can be corrected up to 2 mm.

3) When the cloth cannot be precisely cut although the knife holder is properly corrected, check the state of worn-out of the blade tip of the cloth cutting knife.

1. When replacing the knife, use a new knife holder or a corrected knife holder.

Breakage of the blade tip of the cloth cutting knife may occur.
2. When correcting the knife holder, adjust again the knife pressing amount.
3. When replacing the knife holder with a new one, adjust again the knife pressing amount from 30 or less.

(4) Setting the material thickness of the cloth cutting knife

When the material thickness at the cloth cutting section is excessively thick or the cut length of heavy-weight materials is long, perform the following settings. The low-speed section of the cloth cutting is increased.

1) Turn ON the memory switch.
2) Set the memory switch No. 57 or 58 to the value A or B described in the table below.

	No.57	No.58
Standard value (Up to jeans)	60	80
A (Extra heavy-weight materials)	100	100
B (Extra heavy-weight materials and long cut length)	150	120

• When the set value A or B is selected, the cloth cutting knife operating time is lengthened.
• When the set value is smaller than the standard one, the normal cloth cutting operation may not be performed.

(5) Adjusting the stitch bite width

WARNING :

Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine.

For all types the stitch bite width which is possible to sew is up to 3.2 mm. If the width exceeds 3.2 mm, stitch skipping may occur. When the width exceeding 3.2 mm is desired to be used, use the optional looper (left) and spreader (left). However, for T type, the width is up to 3.2 mm.

1) Open needle rocking adjustment cover ①.
2) Turn the handwheel to bring the needle bar to its lowest position.
3) Loosen fulcrum shaft ② of rocking link B.

• Moving the rocing link B in the direction A increases the stitch bite width.
• Moving the rocking link B in the direction B decreases the stitch bite width.

4) When the stitch bite width is determined, fix fulcrum shaft ② of rocking link B and close the needle rocking adjustment cover.
5) After adjusting the stitch bite width in the aforementioned steps, check the respective items of 11. (2) Timing between the needle and the looper P.45, 11. (3) Clearance between the needle and the looper P.47 and 11. (5) Installing positions of the spreaders and timing to open/close the spreaders P.48.

The engraved marker dot is a standard. Make sure of the amount by putting the needle tip marks on a sheet of paper or the like for the precise measurement.

(6) Adjusting the presser

■ Adjusting the height of the presser

1) Remove auxiliary presser plate cover①.
2) Loosen screw ② and adjust the height of the presser.

The height of the presser is up to 16 mm. If the height is set to more than 16 mm, when the cloth setting position is in the front, and the presser goes up, the presser interferes with the finger guard.

■ Adjusting the presser pressure

Loosen nut ① of the reducing valve and adjust the pressure with adjustment screw ②.

Turning the screw clockwise increases the presser pressure and turning it counterclockwise decreases the pressure.

(7) Adjusting the presser opening amount

■ Adjusting procedure

Loosen setscrew ① and turn adjustment screw ② to adjust the amount.

The position where the presser plate closes will change according to the adjustment.

Turning the adjustment screw ② clockwise decreases the opening amount and turning it counterclockwise increases the opening amount.

The position of the presser (A in the figure below) at the time of sewing (in the state that the cloth open is opened) can be adjusted and the presser can be approached to the throat plate. (Refer to the Engineer's Manual.)

* At this time, there is a case where an additional processing of support plate ③ is necessary to prevent the interference of the cloth cutting knife with support plate ③.

- Checking the cloth open amount at the time of adjustment

1) Turn ON the power and press the [READY] key to light up the sewing LED.

2) Press [KNIFE ①] key to make the LED go out so that the cloth cutting knife is not actuated.

3) Press the presser switch, press [FORWARD 📊] key and the cloth open mechanism opens. The feed base travels to the sewing start position and stops there.

At this time, measure position "A" of the presser plate with vernier calipers or the like.

4) Press [RESET R] key, and the presser goes up, then the cloth open mechanism closes and returns to its origin.

At this time, measure position "B" of the presser plate with vernier calipers or the like. B — (minus) A, (difference between A and B) = cloth open amount

The cloth open amount can be adjusted within the range of 0 to 2 mm. Normally, however, the amount of 0.5 to 0.8 mm is enough.

WARNING :

The confirmation of cloth open amount can be performed by actually cutting cloth in the manual mode. However, the cloth cutting knife works. So, be careful.

(8) Adjusting the feeding amount of the needle thread

■ Adjusting the feeding amount of the needle thread during sewing

Loosen screw ② and move the position of needle thread drawing thread guide ① up or down to adjust the feeding amount.

- When the thread guide slides downward, the feeding amount of needle thread decreases and the needle thread is apt to be tightened.

- When the thread guide slides upward, the feeding amount of needle thread increases and the needle thread is difficult to be tightened.

■ Adjusting the drawing amount of the needle thread at the sewing start

Loosen screws ④ and move thread drawing arm ③ in the direction of A or B to adjust the drawing amount. When the machine is provided with the needle thread clamp unit, if the thread drawing arm is moved in the direction of A, the thread remaining on the needle will be shorter and the thread is easy to be rolled in.

When the machine is not provided with the needle thread clamp unit, and the memory switch No. B8 is "0", "Adjusting the drawing amount of the needle thread at the sewing start" cannot be performed.

• When moving it in the direction of B, the drawing amount of needle thread increases and slip-off of needle thread or the like can be prevented.
• Refer to the Instruction Manual for the needle thread clamp unit.

(9) Adjusting the thread take-up thread guide

Slide up or down thread take-up thread guides ^3 and ^5 installed on thread take-up thread guide installing base ^1 and the trend described below is obtained.

■ Loosen screw ② and move do w nwa rd th r ead ta ke- up thread guide ③.

Effect: • Double chainstitch stitches can easily stand and the sewing possible area is widened. On the contrary, the whole stitches become stiff. (This is suitable for heavy-weight materials.)

• The loop when the looper catches thread becomes larger and stitch skipping is prevented. (Hard-to-slide thread)

■ Loosen screw ④ and move upward thread take-up thread guide ⑤.

Effect: Double chainstitch stitches become flat and the stitches become soft. On the contrary, the sewing possible area is narrowed and stitch skipping is apt to occur. (This is suitable for light-weight materials.)

(10) Adjusting the remaining amount of the gimp (J and C types)

1) Loosen setscrew ① and move to and fro gimp guide ② to adjust the remaining amount of the gimp at the sewing end.
2) For the adjustment, actually sew the remainder of the material or the like and determine the position of gimp guide ② so that the remaining length of the gimp is approximately 4mm at the sewing end.

There is a case where the remaining amount of gimp is not stable when sewing thread or the like is used for the gimp. In this case, insert the gimp in the gimp presser plate ③.

(11) Adjusting the gimp thread tension (J and C types)

Loosen double nut ⑤ to adjust the tension. The standard adjustment value is 2 mm.

When double nut ⑤ is tightened, the gimp tension becomes higher and the length of remaining thread at the time of looper thread trimming becomes shorter. On the contrary, the length of remaining gimp becomes unstable, or the looper thread trimming knife may cut the stitches or materials in case of lightweight materials or elastic sewing products.

1. In case of the light-weight materials or stretchy sewing products, loosen nut ⑤ and fix it.

2. When gimp thread tensio is excessively low or high, there is a case where the length of remaining gimp becomes unstable. The standard adjustment value is 2 mm. Nut⑤ consists of a double nut for locking.

1. The actual thread tension varies in accordance with the kind or thickness of thread used even when the set value of thread tension is the same. Especially, in case of thread of which the surface is hard to slide, the thread tension becomes higher, and even when the set value is as low as 60 to 70, the loop becomes smaller. As a result, stitch skipping may be caused. When using plural threads, it is recommended to make a sewing pattern to which set values of thread tension suitable for the respective threads have been inputted.
2. When the needle thread tension (No. 52) at the end of sewing is set to a high value, stitch skipping at the end of sewing or failure of needle thread take-up may occur.

In case of using Part No. 14050009, refer to the Engineer's Manual.

■ T type (short thread trimming without gimp)

Perform the adjustment of the aforementioned steps 1) to 4) with the left looper (eye looper) instead of right spreader 7.

When the clearance of 1 mm provided between the top end of needle thread trimming knife J ② and the needle (edge of the left looper) is smaller, the knife cuts even the looper thread and the looper thread cannot be retained. When such phenomenon as this occurs, adjust the clearance of 1 mm to rather large.

■ J and C type (short thread trimming)

1) The clearance between needle thread trimming knife J ② and the needle is approximately 1 mm.

Loosen setscrew ① and move needle thread trimming knife J ② to adjust the clearance.

When the adjustment is necessary, remove needle thread trimming adjusting base ⑨ once with setscrew ⑧ and adjust the protruding amount of stopper B ⑬ to 1 to 1.2 mm.

Stopper B ⑬ of the needle thread trimming actuating arm has double screws.

(9) Adjusting the looper thread trimming

WARNING :

Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine.

■ S and R type (long thread trimming)

Looper thread and gimp trimming is operated at the position of the feed base origin and the presser goes up after the trimming.

1) Looper thread and gimp have been adjusted so that they are separated upward and downward by thread handling plate ①.
2) Looper thread is precisely held between looper thread clamp fixing plate ② and looper thread clamp ③ of the plate spring and gimp is precisely held between looper thread clamp fixing plate ② and gimp clamp ④ of the plate spring.
3) Adjustment has been performed so that the top end of counter knife ⑥ is aligned with engraved dot ⑧ of moving knife ⑦ when the stroke of looper thread trimming actuating arm ⑤ is maximum.

When the cut end (thread waste) of looper thread or gimp is clamped with looper thread clamp ③ or gimp clamp ④, clamp failure occurs. As a result, stitch skipping at the sewing start or defective stitches will occur. So, remove the thread waste.

■ J and C type (short thread trimming)

When the feed base is manually moved to the rear until it will go no further, upper knife lower cover ⑤ rides on the cloth cutting knife and remove presser unit ⑥.

Looper thread and gimp trimming is operated at the position of the feed base origin after the presser has been lifted.

1) Looper thread and gimp have been adjusted so that they are separated from the cloth by thread handling plate ④.
2) Driving link ② is actuated and lower knife ③ and upper knife ① engage with each other to perform thread trimming.
3) Upper knife lower cover ⑤ controls the variation of the remaining looper thread when looper thread comes in contact with the blade of the moving knife.

At the time of delivery or when the following presser sets are used, use the cloth cutting knife with the same size as that supplied with the machine. If a cloth cutting knife with different size is used, the knife unit breakage or the like will be caused.

In the state of the standard delivery of J type, the presser of M set is installed

ewing length can be changed as shown below by installing the optional presser set and moving the installing position of the knife unit only.

S set : 16 to 26 mm

WARNING :

To prevent electric shock or personal injury caused by abrupt start of the sewing machine, turn OFF the power and remove the cover after an elapse of 5 minutes or more. To prevent personal injury, be sure to turn OFF the power and replace the fuse with one with same capacity after removing the cause of blown-out of the fuse when the fuse has blown out.

1) Turn OFF the power with the power switch after confirming that the sewing machine has stopped.
2) Draw the power cord from the power receptacle after confirming that the power switch is turned OFF. Then wait for more than 5 minutes.
3) Remove six screws fixing the rear cover of the control box. Then slowly open the rear cover.
4) Grasp the glass section of the fuse to be replaced and remove it.
5) Use the fuse with the specified capacity.

The machine uses the following four fuses.

① and ② For servo-motor power protection 15 A each
(Standard melting fuse pcb direct-installing type)
③ For control power and active tension protection
10 A (Time-lag fuse)
④ For stepping motor protection 6.3 A (Time-lag fuse)

(14) Standard of replacing time of the gas spring

DANGER :

There is a risk of pinching of hand, fingers and arms to cause a serious injury if you raise it when the gas spring does not function, since the sewing machine is very heavy in weight. In order to prevent an accident, be sure to replace the gas spring with a new one before it is too late according to the standard of replacing time (as described below).

Line drawing of a sewing machine with a hand adjusting the hook (no text or symbols)

1) Gas spring is one of the consumables. Gas inside the gas spring will be gone naturally even when the frequency of use is low and the spring cannot display the thrust to secure the safety. In case a force of 156N or more is necessary when passing strings through the front end of machine bed and lifting the sewing machine as shown in the left-hand figure, quickly replace the spring with JUKI genuine gas spring (Part No.: 40061247).

Gas spring is a component that can be used with ease. However, there is a flaw on the rod section or a section that is weak in the side load when the gas spring is fully stretched. Be very careful when performing maintenance or cleaning of the sewing machine.

(15) Replacing the gas spring

DANGER :

Be sure carry out the work while observing the following in order to protect against pinching of hands, fingers and arms between the sewing machine and the bottom cover, which can result in serious injury, when you raise or return the sewing machine from or back to its home position.

1. Be sure to hold the rib on the bed periphery when holding the sewing machine.
2. Be sure to lock the hinge stopper to firmly secure the sewing machine in its raised position.

WARNING :

Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine.

1) Loosen and remove stopper screw ①.

2) Hold with your both hands periphery ribs located on the front side of machine bed, slowly lift the sewing machine, and stop it at the lock position of the intermediate section.

14. MEMORY SWITCH

(1) Operating procedure

Pressing [READY ①key ①, turn ON the power and the mode becomes the memory switch mode. Then various data can be changed.

1) Select memory switch No. with [LEFT +key 2 or [LEFT +key 3.
2) Change the set value with [RIGHT ⊕] key ⑤ or [RIGHT ⊖] key ④.
3) Repeat the steps 1) to 2) when changing other set values.
4) After completion of setting, press [READY Ⓐ] key ⓚ to make the set value store in memory and the memory switch mode ends.

When [RESET ☐key ⑥ is pressed, the mode ends without storing the set value in memory. When turning OFF the power without pressing [READY ○] key ①, the setting is not stored in memory.
