CUTTINGWIDTH

The proper cutting width differs with the type of fabric. Check the seams each time, and adjust the cutting width as follows.

1. Turn the hand wheel toward you until the needles are at the lowest position.
2. Open the front cover and free arm.
3. Turn the cutting width adjustment knob until the looper threads lie along the edge of the fabric.

Adjust to a narrower cutting width if the fabric edges curl when sewing. Turn the cutting width adjustment knob to the right.

Adjust to a wider cutting width if the thread loops off the edge of the fabric. Turn the cutting width adjustment knob to the left.

[ THE PROPER CUTTING WIDTH ]

[ADJUST TO A WIDER CUTTING WIDTH]

[ADJUST TO A NARROWER CUTTING WIDTH]

CHANGING THE NEEDLE

Turn the power switch to "OFF" before changing the needles.

Do not use any needle which is bent or blunt.

1. Turn the hand wheel toward you until the needles are fully raised.
2. Open the front cover and lower the presser foot.
3. Using the hexagon wrench key from the accessory box, loosen the needle clamp screws and remove the needles. Upper left screw for left needle and lower right screw for right needle.
4. Insert the new needle with the flat side to the back into the needle clamp, making sure it is inserted as far up as possible. Tighten the needle clamp screw firmly.

When the needles are set correctly, the left needle is slightly higher than the right one. If needles are not correctly inserted, skipped stitches will result.

This machine is equipped with needle systems. H.A*1 (Needle are household type).

REPLACING THE BULB

Turn the power switch to "OFF" before replacing the bulb.

1. Loosen the screw until it is taken apart.
2. Take off the lamp cover, as figure shown.
3. Push and twist and then remove the old bulb.

Important:

This machine is designed to use 15 watt bulb. The bulb is available from your local dealer.

REPLACING THE CUTTERS

Turn the power switch to "OFF" before replacing the cutter blades.

The lower cutter is made of special material and does not usually need to be replaced. However, should it become damaged, it can be replaced by your local dealer.

To replace the upper cutter when it becomes dull :

1. Open the front cover and turn the hand wheel toward you until the needles are in the lowest position.
2. Using the screwdriver from the accessory box, loosen the upper cutter set screw and remove the upper cutter.
3. Replace the new upper cutter and slightly tighten the upper cutter set screw.
4. Adjust the position of upper cutter so the edge of the upper cutter overlaps 0.5-1.0mm from the edge of lower cutter as shown below.
5. Tighten the upper cutter set screw firmly and close the front cover.

THREE THREAD NARROW AND WIDE OVERLOCK STITCH

This machine is a 3/4 thread convertible.
overlock.

Remove either the right or left needle. Your machine is now ready for use as a 3-thread overlock.

Refer to "CHANGING THE NEEDLE".

Using the needle on the right only, the stitch width is 4 mm (0.16").

Using the needle on the left only, the stitch width is 6 mm (0.24").

FREE ARM SEWING

Remove the support bed as illustrated which easily converts from a flat bed to free arm. Convenient for sewing pant legs, sleeves and cuffs, etc.

CONVERTIBLE PRESSER FOOT

The special presser foot, is set for normal overlock with the letter N adjacent to the vertical screw at front of presser foot. When you need to sew a rolled edge, simply loosen the large screw slightly and move the finger that protrudes from left side of foot forward until is stops, then re-tighten the screw. The letter R will now be adjacent to screw.

ROLLED AND NARROW EDGE

To carry out either of the above sewing tasks proceed as follows.

(1) Refer to page 23 for special foot position setting.
(2) Turn the handwheel toward you until needles are fully raised.
(3) Open front cover and remove left needle. See page 20.
(4) Set stitch length between 1.0 - 2.0 mm . See page 18. Also ensure that differential control is set at 'N' position.
(5) Adjust stitch width, as shown on page 19.
(6) If not already threaded re-thread the machine.
(7) Place fabric under presser foot and start to sew.

Always test the stitch and tension settings on scrap fabric before sewing on an actual garment. When either Rolled or Narrow hemming, we recommend you change the threads as shown on page 25.

ALWAYS remember to re-set the special foot for normal serging after you have finished your rolled edge procedure.

[ROLLEDEDGE]

With a rolled edge the loops formed by the lower looper thread should be pulled to the underside of the fabric. This is done by setting the tensions as shown on page 25.

[NARROW EDGE]

For seams on sheer or lightweight fabrics, set tensions as shown on page 25 for a balanced tension.

Important: If necessary, adjust the stitch length and cutting width.

[ROLLED HEMMING]

[NARROW HEMMING]

DIFFERENTIAL FEED

The differential feed prevents wavy seams in knitted fabrics and also movement between the layers of fabric. It also ensures pucker-free seams on lightweight fabrics.

[DIFFERENTIAL FEED MECHANISM]

There are two sets of feed teeth, one front and one rear. The two sets of feed teeth move independently. Differential feed allows the two sets of feed teeth to move at different rates. Differential ratio 0.7-2.0.

[ADJUSTING THE DIFFERENTIAL FEED]

The differential feed can be adjusted by simply turning the differential feed adjustment knob in the direction desired. Adjustment of the differential feed can be made while sewing.

Important:

When sewing without differential feed, the adjustment knob for the differential feed should be set on the "N" position.

[WAVY KNITS & GATHERING]

For perfectly flat seams in stretchy knit garments, the front feed teeth need to feed faster than the rear feed teeth to prevent stretching the fabric. To Gather, the front feed teeth will also need to feed faster than the rear feed teeth. By using a long stitch length, (See page 26 to adjust). your fabric will easily gather. Set differential feed motion at "G".

[STRETCHING TO PREVENT PUCKERING]

To avoid any puckering in seams on lightweight woven fabrics or smooth nylon, the rear feed teeth must feed faster than the front feed teeth. The front feed teeth, therefore, holds the fabric taut to prevent puckering. Set the differential feed motion at "S".
