When the machine is not in use, it is recommended that the electric supply plug is disconnected from the wall

socket to avoid any possible hazards.

Notes on the motor

- The maximum operating speed of this sewing machine is 1,300 stitches per minute, which is quite fast

compared to the normal operating speed of 300 to 800 stitches per minute for the ordinary sewing machine.

- The bearings in the motor are made of a special sintered, oil-impregnated alloy mounted in oilsoaked felt to

withstand long hours of continuous operation.

- Continuous operation of the sewing machine can cause heat to build in the motor area, but not enough to

adversely affect its performance.

It is important to keep fabric and paper away from the air openings on the back and sides of the machine so air

can get to these openings.

- When the motor is running, sparks can be seen through the air openings in the motor bracket on the side

opposite the hand wheel. These sparks are produced by the carbon brushes and the commutator, and are part

of the machines normal operation.

Differential feed

This serger is equipped with two sets of feed dogs

under the presser foot to move the fabric through

the machine. The differential feed controls the

movement of both the front and the rear feed dogs.

When set at 1, the feed dogs are moving at the

same speed (ratio of 1). When the differential feed

ratio is set at less than 1, the front feed dogs move

slower than the rear feed dogs, stretching the

fabric as it is sewn. This is effective on lightweight

fabric that may pucker. When the differential feed

ratio is set at greater than 1, the front feed dogs

move faster than the rear feed dogs, gathering

the fabric as it is sewn. This function assists in

removing the rippling when serging stretch fabrics.

An example

When stretch material is sewn without using the

differential feed, the edge will be wavy.

To get smooth ﬁnish, adjust the feed ratio from 1.0

toward 2.0.

(The feed ratio required depends on the elasticity

of the material.)

The more elastic the material, the further toward

2.0 the differential feed ratio should be set. Test

sew with a scrap of the fabric to ﬁnd the correct

adjustment.

CAUTION

When sewing thick non-stretchable material such

as denim, do not use the differential feed as it may

damage the fabric.

Adjusting the presser foot pressure

Turn the pressure adjustment screw on the top

left of the machine. You can adjust by referring the

value on the screw.

The normal setting is "2".

Tension adjustment dial

There is a thread tension dial for each needle

thread, the lower looper thread and the upper

looper thread. The correct thread tension may

vary according to the type and thickness of the

fabric and the type of thread used. Thread tension

adjustments may be necessary for any change in

sewing materials.

CHAPTER 5

SEWING

Stitch selection

Select the stitch pattern before you start sewing.

This sewing machine can sew ﬁve different stitches

by following the simple steps below:

Four-thread overlock stitch

Use all four threads and two needles for producing

four-thread overlock stitches.

Use: Produces strong seam. Ideal for sewing knits

and wovens.

Three-thread overlock stitch

5 mm (3/16 inch)

Use three threads and the left needle, producing 5

mm (3/16 inch) seams.

Use: For overlock stitching on suits, blouses,

slacks, etc. Ideal for medium to heavy materials.

NOTE:

Remove the right needle when sewing this

overlock stitch.

Three-thread overlock stitch 2.8 mm

(7/64 inch)

Use three threads and the right needle, producing

2.8 mm (7/64 inch) seams.

Use: For overlock stitching on suits, blouses,

slacks, etc. Ideal for ﬁne to medium materials.

NOTE:

Remove the left needle when sewing this overlock

stitch.

Narrow overlock stitch 2.0mm (5/64

inch) and

Rolled hemming stitch 2.0mm (5/64

inch)

Use as decorative or ﬁnishing stitch. See "Narrow

overlock/ Rolled hemming stitch" in this chapter for

details.

NOTE:

You can use the optional accessory foot for even

more varieties of stitches. See CHAPTER 8 for

details.

Test sewing

Test-sew before you start sewing.

1. Set all the thread tension to "4".

2. Thread the machine and pull all threads out

about 15 cm (6 inches) behind the presser foot.

3. Place a piece of scrap material under the

presser foot for test sewing.

NOTE:

Always lift the presser foot before placing the

fabric under it. You cannot start sewing by just

running the fabric under the foot without lifting

the presser foot.

English

3. The fabric will be fed automatically. You need

only guide it in the required direction.

4. Check the stitch formation (stitch chain) to

see if it is uniform. If the stitch is not uniform,

re-check that the threading has been done

properly and in sequence.

5. Follow the Seam Allowance Guide for

consistent cutting of the fabric seams. The

scale of Seam Allowance Guide shows 9.5,

12.7, 15.9, and 25.4 mm (3/8, 1/2, 5/8, and 1

inches) when the stitch width dial is set to "5".

Presser foot

Upper knife

Seam Allowance Guide

To remove work

When the seam is ﬁnished, keep the machine

running at a low speed to obtain chaining-off. Then

cut the stitches 5 cm (2 inches) from the work.

If feeding for chaining-off is not enough, pull the

thread gently.

4. Holding all threads with your left hand, turn the

hand wheel slowly a few times toward you,

and check to see that the threads entwine

themselves before using the foot controller to

sew.

Chaining-off

After test-sewing, continue to depress the foot

controller slightly and chain off 10 cm (4 inches).

The threads will entwine themselves into a chain

automatically.

NOTE:

If the thread tension is not correctly balanced, the

chaining-off result will be uneven. If this happens,

pull the threads slightly. Check the threading order

and adjust the thread tension to create an even

chain. (See CHAPTER 1 "Tension adjustment

dial".)

To start sewing

1. Thread the machine and pull all threads out

about 15 cm (6 inches) behind the presser foot.

2. Lift the presser foot and place the material well

underneath the presser foot before starting to

sew. Slowly sew a few stitches by turning the

hand wheel.

To secure chain

There are two methods available to secure the

chain.

Method 1

Secure the chain of the beginning and the end of a

stitch with your machine.

At the beginning of a stitch

1. Sew a few stitches, after chaining-off for 5 cm (2

inches).

2. Stop the machine and raise the presser foot.

3. Put the chain under the presser foot, and serge

over it pulling toward you.

4. After sewing a few stitches, cut off the extra

chain with the knife as illustrated.

At the end of a stitch

1. At the end of the seam, sew one stitch out of

the fabric before stopping the machine.

2. Raise the presser foot and the needles, then

reverse the fabric.

3. Lower the needles and the presser foot at the

same position.

4. Serge over the seam, taking care not to cut the

serged seam with a knife.

5. After sewing a few stitches, serge off the fabric

as illustrated.

6. Cut the threads with scissors.

Method 2

WIth this method, the chain of the beginning and

the end of a stitch can be secured in the same

manner.

1. Tie the thread unpicked from chain.

2. Insert the chain into the end of the seam, using

a hand sewing needle with large eye.

3. Fix the chain with a drop of fabric glue, and cut

the extra stitches after drying.

English

If threads break during sewing

Remove the material and re-thread in the correct

order, Lower looper, Upper looper, right needle and

then the left needle (to re-thread, see CHAPTER

3 "Threading"). Replace the material under the

presser foot and sew 3-5 cm (1-1/8 to 2 inches)

over the previous stitches.

CAUTION

Do not leave straight pins in the fabric when

sewing as they will damage the needles and

knives.

To sew ﬁne materials

1. Adjust the presser foot pressure to prevent the

material from puckering and to allow sewing

of curves. (See CHAPTER 1 "Adjusting the

presser foot pressure".)

2. Loosen the thread tension, but remember that if

the tension is too loose, the thread may break

and stitches may be skipped.

Narrow overlock/ Rolled hemming stitch

The Narrow overlock/Rolled hemming stitch is

a decorative ﬁnish for lightweight to midweight

fabrics. It is often used to complete the edge of

a fabric. This stitch is sewn by removing the left

needle and using the 3-thread overlock stitch.

Instructions for both narrow overlock/

Rolled hemming stitches

CAUTION

Turn off the main power and light switch before

removing/ installing a needle.

1. Remove the left needle.

NOTE:

For the recommended thread and needle, see

CHAPTER 4 "Sewing materials, threads, and

needles comparison chart".

2. Thread the machine for a three thread overlock,

using the right needle.

3. Remove the stitch ﬁnger <A>.

Raise the presser foot lever.

Pull all threads toward the back of the

machine.
