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.)

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

(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.

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.

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 specied time. 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.)

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. Contact face of the knife holder with the cloth cutting knife. (4) Setting the material thickness of the cloth cutting knife (3) Worn-out of the knife holder face

Can be corrected up to 2 mm.

1) Turn ON the memory switch.

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.

When replacing the knife holder with a new one, adjust again the knife pressing amount from 30 or less.

  • 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. 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. 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.

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.

(14) Standard of replacing time of the gas spring

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 gure, 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 aw 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.

There is a risk of pinching of hand, ngers 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). ENGLISH (15) Replacing the gas spring

1) Loosen and remove stopper screw

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. Do not hold feed base and feed guide shaft xing base

3) Further, support periphery ribs

of the machine bed with your left hand, hold grip

of the hinge stopper section with your right hand, release the lock, and slowly lift the sewing machine. When the sewing machine starts lifting, set free the hinge stopper section held with your right hand and support the periphery ribs with your both hands.

Be sure carry out the work while observing the following in order to protect against pinching of hands, ngers 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 rmly secure the sewing machine in its raised position.

Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine.58

4) Further, lift the sewing machine and adjust so that

moves to the last lock position of the hinge stopper.

If the hinge stopper is not locked, the sew- ing machine can drop to pinch hands, n- gers and arms leading to a serious injury. Make sure that the hinge stopper is locked with support shaft

7) When assembling is completed, return the sewing

machine to its home position. When returning the sewing machine, support periphery ribs

of the machine bed with your left hand, hold grip

the hinge stopper section with your right hand, pull it to this side (direction A) to release the lock and slowly lower the sewing machine after confirming that there is no tool such as screwdriver and the like in the bottom cover.

8) Take your right hand off from the hinge stopper

section, support periphery ribs

of machine bed with your both hands and further lower the sewing machine.

1. Do not lower the sewing machine while

keeping pulling the hinge stopper in direction A, in order to prevent pining of ngers, hands and arms under the sewing machine leading to a serious injury.

and feed guide shaft xing base

Take care to prevent pinching of hands and ngers between the sewing machine and the bottom cover. In particular, never lower the sewing machine holding parts other than the bed rib with two or more workers, since doing so can cause pinch- ing of hands, ngers and arms leading to a serious injury.

9) The lock works two times for the safety while the

sewing machine is lowered. Every time, support the periphery ribs of machine bed with your left hand, hold the grip of hinge stopper section with your right hand, release the lock, and slowly lower the sewing machine.

10) When the sewing machine is completely lowered,

attach stopper screw

that has been removed before.0 Long thread trimming Short thread trimming S (C standard) Short thread trimming M (J standard) Short thread trimming L OFF OFF OFF OFF DIP-SW
