in a polarized main socket only one way.

If the plug does not t fully in the polarized main socket, reverse the plug. If it still does not t, contact a qualied electri-

cian to install the proper polarized main socket. Do not modify the plug in any way. (for USA, Canada only)

Polarized plug (for USA, Canada only)

Preparing the machine / Using the machine

Waste collector

Clip the waste collector into the opening on the looper cover. It catches the cut-off fabric as you sew, keeping your working area neat and tidy.

Thread / cones /

spools

The anti-vibration cone should be used with the wider edge at the bottom on the spool holder pin when sewing with cones.

Household spools

Remove the anti-vibration cones. Place spools on spool holder pins and push the spool caps on with the rounded side downwards.

Large spools

If large industrial spools are used, position the anti-vibration cone upside down on the spool holder pin, i .e. with the wider edge at the top.

Thread net

If the threads slip and get twisted, cover the looper spools with the net supplied in the accessory bag.

Using the machine

Safety device:

The sewing machine is equipped with a safety device in

order to prevent malfunction. In any of the following cases, the safety device works to prevent the sewing machine from running. * When the looper cover is opened * When the cloth plate is opened * When the presser foot is raised

Handwheel

The handwheel turns forward, i.e. in the same direction as on a household sewing machine.

* The needle is brought to its upper end by

aligning the “ cover with the “

” marking on the side of the front

” marking on the handwheel.

Using the machine

Two step presser foot lifter with integrated front

foot lift

To raise the presser foot, lift the presser foot lever on the rear of the machine, until it engages (A). It can be raised again to the maximum height and held in this position to provide more space between presser foot and stitch plate (B). When the foot is raised (A and B), the front of the foot is automatically lifted.

Note:

When the presser foot is raised, all the tensions are released making it easier to thread the machine.

Changing the presser foot

Switch the machine off (power switch”0”) and deactivate the upper knife.

• Raise the presser foot.

• Turn handwheel towards you until needles are fully raised.

Match the matching up marks on handwheel and side cov-

er. Press the catch (C) to release the presser foot from the clamp. Raise the presser foot shank to the highest position (B) and remove the presser foot to the left. To attach the presser foot, place it under the shaft. The groove in the shaft should line up exactly with the presser foot pin (D). Lower the presser foot lifting lever and check that the groove in the shank should line up exactly with the presser foot pin (D). If it is not lined up, press the catch (C) to line up.

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.

Caution:

To activate the upper knife, bring the upper knife changeover knob at position E. Turn the handwheel by two revolutions by hand.

How to use the presser foot

Use the marker on the presser foot as a guide when placing the material under the presser foot. (F) Left needle position (G) Right needle position (H) Knife position (when the lower knife adjusting knob is set

at scale mark “1.5”)

The knife position represents the position at which the

material is cut.

Inserting the needles

Needles can be inserted quickly and easily with the practical

needle inserter (A).

Switch the machine off (Power switch to “0”) Disconnect machine from electricity supply.

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

Lower the presser foot.

Using the small screwdriver, loosen the needle setscrews and remove the needles (B).

Place the right-hand needle, at side towards the back, into

the hole of the needle inserter and insert the needle as far as possible into the needle clamp. Tighten the setscrew lightly and then insert the left-hand needle in the same way and tighten both setscrews (C).

Needle and thread

Needles

Needles must be in perfect condition. Problems can occur if needles:

Needle and thread

The needle size used depends on the thread. The needles should be in accordance 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. * It is recommended to use JLx2 needle, especially when sewing thick materials, overlapped section, etc,

with overlock machine.

A are bent. B are damaged or blunt. C have hooked points.

Thread/decorative threads

Sewing and special overlock threads are manufactured in a wide variety of types, weights and combination

of bres. It is worth investing in good quality threads for perfect sewing results. Decorative threads specially

made for overlockers (available on cones) are also becoming widely available. We recommend following the basic guidelines when using special threads on your overlocker:

- Purchase threads on cones or spools which are produced exclusively for overlocking.

- When using normal spools, use the spool caps (in accessory bag).

- Only use decorative threads in the loopers. The thread must move easily and without resistance through the thread guides and looper eyes.

- The thicker the thread, the longer the stitch length (3-4).

- The thicker the thread, the looser the tensions.

- Sew slowly when using decorative threads. Pull the thread chain gently to the rear when starting to sew.

Always test sew decorative threads before starting to sew your work.

Adjustments and settings

Stitch length

It can be adjusted while sewing. The stitch length is innitely variable from 1-4mm. Most overlock work is done with a basic setting of 2.5mm. For roll hemming or narrow overlocking, it is best to set the dial at “1 to 1.5”.

For blind stitch which requires the “use of separately-available

presser foot”, set the dial at “4”.

Cutting width

Switch the machine off (Power switch to “0”) Disconnect machine from electricity supply.

• Raise the upper knife.

• Turn cutting width adjustment dial in the desired direction.

• Lower upper knife. 1 = 3–5 mm seam width 2 = 4–6 mm seam width 3 = 5–7 mm seam width 4 = 6–8 mm seam width

5 = 7–9 mm seam width The position of the lower knife determines the width of the seam. Reduce the cutting width if the edges of fine fabric curl up when being sewn (A). Increase the cutting width if the loops seem to be too loose (B).

WARNING

Do not carry out sewing with a marking pin stuck in the material. In addition, do not attempt to cut anything other than fabric and thread with the upper/

lower knives. Be aware that doing so can cause nee-

dle break or personal injury.

Adjustments and settings

N(1)

Differential feed

There are two feed dogs one front (C) and one rear (D). The two feed dogs move independently and the distance each feed dog travels during one complete movement can be adjusted. The differential feed prevents fluting or waving in knitted or stretch fabrics and movements between the layers of fabric. It also ensures pucker-free seams in smooth fabric such as nylon or closely woven fabric.

Perfectly at seams in knits or stretch fabrics.

The distance travelled by the front feed dog should be greater than that of the rear feed dog. The front feed dog, therefore, feeds an amount of fabric which the rear feed dog can take up behind the needle without stretching the fabric. (E)

Pucker - free seams in nylon or closely woven

fabrics.

The distance travelled by the rear feed dog should be greater than that of the front feed dog. The front feed dog, therefore, holds the fabric back so that the rear feed dog can take it up behind the needle without any puckering. (F)

Adjusting the differential feed

The differential feed can be adjusted by simply turning the differential feed adjustment dial in the direction desired. Always

make a trial run. The differential feed is innitely variable and

can be adjusted while sewing.

Adjustments and settings

Gathering

Using the differential feed, a single layer of fabric can be gathered before sewing it to the garment. For example, sleeve heads and lower edges, yokes, lace edging or frills.

Adjustment:

• Stitch: 4-thread overlock

• Differential feed: 2

• Stitch length: 3-4

• Cutting width: 2-3 Increase the needle thread tension (6-8) for a tighter gather.

Roll hemming

• Turn the handwheel towards you until the needles are fully raised.

• For roll hemming, pull the overlocking width changeover knob toward you and check that the overlocking claw retracts. (C).

• For overlocking, push the overlocking width changeover knob away from you to check that the overlocking claw projects. (D).

The roll hemmer is fully integrated in the machine. The edge of the fabric will be automatically rolled over, producing a very

narrow, ne seam or hem. Roll hemming is ideal for nishing edges on all ne fabrics,

such as evening clothes, lingerie, scarves, frills and also for curtains and napkins.

Presser foot pressure

The presser foot pressure is factory adjusted to a medium setting. Align the marker line on the presser foot pressure regulating knob with the upper end of the top cover. Position of knob for normal pressure (M) = Medium. More pressure: for thick or stiff fabrics such as denim, tweed,

rm linen (H) = High.

Less pressure: for light-weight or sheer fabrics and knits (L) = Low.

Threading preparations / Tips

1. Extend the retractable support rod tted with open

thread guide as far as it goes.

2. Raise the presser foot. (Tension disk opens.)

3. Open the looper cover.

Looper threader

How to use the looper threader

To thread woolly thread or any thread that cannot pass smoothly through the threading holes, it is recommended either to use the “looper threader” supplied in the accessory bag, or to prepare an approximately 30 cm long spun thread or the like, tie it at the end of the woolly thread, pass the spun thread through the threading hole and pull it until the woolly thread passes through the hole. (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 out from the end of the looper.

Caution:

Do not press the air-control pushbutton.

Note:

Caution:

After the completion of threading of the upper and lower loopers, return the threading lever to its home position. If not, the looper cover cannot be closed.

Trial sewing

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 fingers 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.

* Chain-off thread is stitch-formed thread with no material.

1. Upper looper thread (purple).

2. Lower looper thread (red).

3. Right-hand needle thread (green).

4. Left-hand needle thread (beige). Perfect stitch formation is when both looper threads meet at the fabric edge. The needle threads form straight stitches for a stretchy and durable seam.

Thread tension

Thread tension should be properly adjusted to suit the various types of work. The ideal tension setting for most fabrics and threads is be-

tween 3 and 5. However this can vary quite considerably when special threads such as lament, woolly nylon, buttonhole twist

(cordonnet), pearl yarn or decorative threads are used. Only use decorative threads in the looper. The thread must move easily and without resistance through the looper eye.

Innitely variable adjustments can be made from 1 - 9.

Turn the dial downwards for less tension. Turn the dial upwards for more tension.

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).

• The fabric puckers during sewing:

Loosen the right- or left-hand needle thread tension, green

or beige (F).

Practical Sewing - Overlock

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 handwheel 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.

• Raise the tip of the presser foot and place work underneath. Sew.

Carrying out hemming and narrow over-

locking

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 hemming

1. Install the right needle only.

2. Pull the overlocking width changeover knob to-

ward you to lower the overlocking claw.

3. Set the lower knife adjusting knob at the scale

mark “1 to 1.5”.

4. When using filament 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.

Practical Sewing - Overlock

Wrapped overlocking with three threads

For wrapped overlocking with the right needle (3

to 7 mm in width)

1. Remove the left needle.

2. Thread the upper and lower loopers in the same manner as the standard sewing (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 the same manner as the standard sewing (2-needle, 4-thread).

2-/3-thread changeover attachment

Use the 2-/3-thread changeover attachment when it is desired to carry out 2-needle overlocking, cover stitch (flatlock) or 2-thread hemming.

1. Turn off the power switch.

2. Press the 2-/3-thread changeover attachment mounted on the upper looper to the left.

3. Check that the projection of the 2-/3-thread changeover attachment is inserted into the hole in the top end of the looper.

In the aforementioned state, the upper looper thread is not fed. However, the lower looper thread is fed to form 2-thread stitches.

缝纫中断线、缝口合拢

马上停止缝纫，取出面料。重新穿线。如果下弯针断线，则需要剪断左、右机针线，并从下面拉掉余线。先穿弯针线，再穿机针线。在离接口处2-3cm重新开始缝纫。

缝口的拆法

用锋利的剪刀剪断线圈（C）, 拉机针线（D），针脚就被拆开。

Practical Sewing - Overlock

Cover stitch with three threads (atlock)

1. Deactivate the upper knife.

2. Use a decorative thread as the upper looper thread. (Filament thread is best-suited as the needle thread and the lower looper thread. However, spun thread can also be used.)

3. Adjust the tension regulating dial and stitch length adjustment dial. Adjust the dials so that the thread tension is slightly reduced.

Scale mark of tension regulating dial

Stitch length adjustment dial 2 - 2.5

4. Use either the left needle or the right needle only.

In the case of the left needle: Wide cover stitches are

sewn. (5 to 9 mm)

In the case of the right needle: Narrow cover stitches are

sewn. (3 to 7 mm)

5. Fold the material in two. Carry out sewing with a preset overlocking width.

6. After the completion of sewing, unfold the material.

Thread breakage during sewing

Sew off immediately at an angle and remove the work. Re-

2-3 cm

thread. If the upper or lower looper thread breaks during sewing, re-threading is necessary. Remove both the broken and unbroken looper threads. Then, set the threading lever to the threading side to carry out threading of the upper and lower loopers. First thread the looper and then the needles. Start sewing again about 2 - 3 cm in front of the break.

Unpicking seams

Using sharp scissors, cut the loops (C). Pull the needle thread (D) and the stitches will come undone.

Practical Sewing - Overlock

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

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 from the left side.

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

* If you do not sew the chain-off thread on the material, pro-

duce a longer chainoff thread at the beginning and end of sewing. Then, make a knot of the chainoff thread or put the chain-off thread under the seam with a wool needle.

* When stitches cross each other, chain-off thread is auto-

matically secured.

2) Securing thread ends at the end of sewing

1. Stop the needle at the end of material.

2. Lift the needle.

3. Raise the presser foot.

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

enters the outside edge of nished seam.

5. Lower the presser foot.

6. Carry out sewing to produce chain-off thread by 2 to 3 cm taking care not to allow the nished seam to come in contact with the upper knife. Remove the material.

7. Secure the chain-off thread.

Practical Sewing - Overlock

In the case of securing thread ends with a wool needle: (A)

Leave a 2 to 3 cm long chain-off thread at the beginning and end of sewing.

Put the chain-off threads in the nished seam by means of a wool needle.

In the case of securing thread ends with glue for handicraft: (B)

Apply a little amount of glue for handicraft at the root of chain-off thread on the material. Cut out the excess of chain-off thread after the glue has dried.

Securing thread ends by making a knot: (C)

Bind all threads together and make a knot at the nearest position of the material. Then, cut out the excess of the threads.

Maintenance

Cleaning and lubricating

As you use the sewing machine, lint is likely to accumulate

in the sewing machine. It is necessary to remove the lint pe-

riodically. Since lint accumulates particularly in the sections

around the throat plate and lower knife, remove the lint from

those sections on a periodical basis. (A)

When cleaning the pipes of the upper and lower loopers, use

the “looper threader” supplied in the accessory bag. (Refer to

page 21 for how to use it.)

The sewing machine uses special materials for important

parts. Apply one or two drops of machine oil to the sections

illustrated.

Turn off the power switch and disconnect the power plug from the wall outlet before starting cleaning

or lubricating the machine.

Precautions to be taken when handling oil

* In the event the oil gets in the eye or adheres on skin, immediately wash it off in order to prevent irrita-

tion and rash. * If swallowed accidentally, immediately seek for medical advice in order to prevent diarrhea and vomiting. * Keep the oil away from children. * Oil disposal is obliged by legislation. Dispose of the oil properly in compliance with the relevant legisla-

tion.

To carry out cleaning with the cloth plate opened

Be sure to turn off the power switch before opening the cloth plate.

• How to open the cloth plate

Push this side of the cloth plate to the left to open it.

• How to close the cloth plate

Push the cloth plate toward the sewing machine.

Replacing the knife

It is not normally necessary to replace the lower knife since it is made of special ultrahard material. If the knife blade tip has chipped, replace the knife with a new one. Contact your distributor for the replacement of the lower and upper knives.
