“SAVE THESE INSTRUCTIONS”

“This overlock sewing machine is intended for household use only.”2 Danger warning which is not specied There is a risk of electrical shock There is a risk of re There is a risk of injury to hands, etc. Prohibited matter which is not specied Disassembly/ alteration is prohibited Do not place ngers under the needle Do not pour oil, etc. Generally required behavior Disconnect the power plug Congratulations on your purchase of a JUKI sewing machine. Please be sure to read safety precautions in “To use the sewing machine safely” in the Instruction Manual before use to fully understand the functions and operating procedures of the sewing machine so as to use the sewing machine for a long time. After you have read the Instruction Manual, please be sure to keep it together with the warranty so that you can read it whenever necessary. To use the sewing machine safely Marks and pictographs included in the Instruction Manual and shown on the sewing machine are used so as to ensure safe operation of the sewing machine and to prevent possible risk of injury to the user and other people. Warning marks are used for different purposes as described below. WARNING Indicates that there is a possible risk of death or serious injury if this mark is ignored and the sewing machine is used in a wrong manner. CAUTION Indicates the operation, etc. which can cause a possible risk of personal injury and/or physi- cal damage if this mark is ignored and the sewing machine is used in a wrong manner. Pictographs mean the following:3 ● Do not wipe the sewing machine with solvent such as thinner. When the sewing machine is soiled, put a small quan- tity of neutral detergent on a piece of soft cloth and carefully wipe off the sewing machine with it. ● Be sure to use the sewing machine in the tempera- ture range from 5ºC to 40ºC. If the temperature is excessively low, the machine can fail to operate normally. WARNING For the combination of the material and the thread and needle, in particular, refer to the explanation table in “Replacement of the needle”. If the needle or thread does not match the material used such as in the case that an extra heavy-weight material (e.g., denim) is sewn with a thin needle (#11 or higher), the needle can break resulting in an unexpected personal injury. Other precautions ● Do not put the sewing machine under the direct sun- light or in a humid place. Be aware that the following state can take place since the sewing machine incorporates semi-conductor electronic parts and precise electronic circuits.

• The operating temperature of the sewing machine is between 5ºC and 40ºC. Do not use the sewing machine under the direct sunlight, near the burning things such as a stove and candle, or in a humid place. By so doing, the tempera- ture in the interior portion of the sewing machine can rise or the coating of the power cord can melt, causing re or electrical shock.4

To carry out sewing without cutting the material (the upper knife is deactivated) Turn off the power switch before deactivating the upper knife.

1. Lower the upper knife changeover knob in the direction of the arrow.

2. Check to be sure that the knife is lowered.

Needle and thread The needle size used depends on the thread. The needles should be in accor- dance with thread used. When sewing, the thread is fed through the long groove in the needle. If the needle is too ne, the thread does not t into the groove and stitches will be skipped. Use needles No. 70 - 90.

(The looper threader can also be used as a cleaning tool for pipes.)

1. Raise the threading changeover lever in the direction of the arrow.

Turn the handwheel toward you until it clicks.

2. Pass the thread through the looper threader ring.

3. Pass the looper threader through the looper by hand until it comes

1. Close the looper cover. Turn the power on.

2. Check that the upper knife is raised.

3. Lower the presser foot.

4. While holding the thread trailing from the rear of the presser foot by hand,

depress the controller to produce chain-off thread by 6 to 7 cm.

5. Raise the front side of the presser foot with ngers and insert the material

under the presser foot until the upper knife is reached.

6. Start the sewing machine.

7. After the completion of sewing, produce chain-off thread by 5 to 6 cm.

8. Put the chain-off thread over the thread trimming blade for trimming.

3. Right-hand needle thread (green).

4. Left-hand needle thread (beige).

Perfect stitch formation is when both looper threads meet at the fab- ric edge. The needle threads form straight stitches for a stretchy and durable seam. Control de la costura de prueba Overlock de 4/3 hilos

Adjusting the thread tension Turn the tension dials by quater or half number, then test sew again and check the result.

• The loops are formed on the underside. Tighten the upper looper thread tension, (purple) or loosen the lower looper thread tension, red (A).

• The loops are formed on the upper side. Tighten the lower looper thread tension, (red) or loosen the upper looper thread tension, purple (B).

• The right-hand needle thread forms loops on the underside. Tighten the right-hand needle thread tension, green (C).

• The left-hand needle thread forms loops on the underside. Tighten the left-hand needle thread tension, beige (D).

• The edge of the fabric curls up, tension of both looper threads is too tight: Loosen upper and lower looper thread tensions, purple and red (E).

F49 Sewing in tape The standard presser foot is equipped with a tape guide. A tape can be sewn into the shoulder or side seams of garments made from knits or stretch fabrics to prevent stretching.

• Turn handwheel towards you until needles are fully raised. Match the matching up marks on hand- wheel and side cover.

• Raise the presser foot.

• Lay the tape under the presser foot and slide it carefully into the tape slot.

• Lower the presser foot.

• Sew a few stitches on the tape.

• Loosen the setscrew (A) and adjust the tape guide to suit the width of the tape (B).

• Re-tighten setscrew.

Carrying out hemming and narrow overlocking The sewing machine incorporates the hemming device to enable roll hemming and narrow overlocking. The sewing machine is able to overlock the material edges such as bottoms and sleeve cuffs beautifully while automatically folding them inwardly.Preparation for hemming1. Install the right needle only.2. Pull the overlocking width changeover knob toward you to lower the overlocking claw.3. Set the lower knife adjusting knob at the scale mark “1 to 1.5”.

4. When using lament thread or woolly nylon thread, set the stitch length adjustment dial (stitch

length) at “1 to 1.5”.Roll hemming (A)The roll hemming is the stitch system that laps the material edge with the upper looper thread.Narrow overlocking (B)The narrow overlocking is the overlock stitch system overlocking width of which is narrower than the standard one. La realización de dobladillos y sobrehilado estrecho La máquina de coser incorpora el dispositivo de dobladillar para permitir dobladillo enrollado y sobre- hilado estrecho. La máquina de coser es capaz de hacer sobrehilado en los bordes de los materiales como fondo y puños de manga bellos mientras que automáticamente los pliega hacia el interior.Preparación para dobladillar1. Coloque la aguja derecha solamente.2. Tire del pomo del cambio de anchura del overlock hacia usted para bajar el áncora de so-brehilado.3. Ajuste el pomo de ajuste de la cuchilla inferior a la marca de la escala “1 a 1,5”.

1. Remove the left needle.

2. Thread the upper and lower loopers in

the same manner as the standard sew- ing (2-needle, 4-thread). For wrapped overlocking with the left needle (5 to 9 mm in width)

1. Remove the right needle.

2. Thread the upper and lower loopers in

Securing thread ends at the beginning and end of sewing Overlock stitches can unravel if the threads are not secured at the beginning and end of sewing. Secure the thread ends. Securing thread ends with the overlock machine

1) Securing thread ends at the beginning of sewing

1. Pull out chain-off thread produced at the beginning of sewing by 3 to 4 cm.2. Sew the material by two or three stitches.3. Lower the needle and raise the presser foot.

4. Stretch the chain-off thread to put it between the presser foot and the material

5. Lower the presser foot and sew the chain-off thread on the material.

2) Securing thread ends at the end of sewing

1. Stop the needle at the end of material.

4. Turn the material upside down. Lower the needle so that it enters the out-

side edge of nished seam.

5. Lower the presser foot.
