– It is very important to select the right needle for the type of thread and fabric used. – Inappropriate needles can cause bad embroidery , thread breaks, skipped stitches, etc. – For normal embroidery , use a DB×K5 needle.

8.2.2) Relationship between needle and thread

– Inadequate selection of threads and needles can result in thread breaks, skipped stitches, as well as in bad-

quality embroidery .

– Refer to the following table for threads and needles used in normal embroidery .

8.2.3) Changing the needle

– Make sure the needle is completely clear of the needle plate before changing it. If the needle is not clear of

the plate, use the main shaft handle, manually turn the main shaft to put the needle in the right location for change.

– When inserting the needle, make sure that the

groove of the needle is facing front.

– End tip of the needle should be inserted

completely into the needle bar.

Hole for inserting needle

Slit on the front of the needle

1) Turn OFF the machine according to the safety rules before turning the main shaft manually.

2) Immediately remove the main shaft handle afterward: it is dangerous to operate the machine with the handle inserted.

CAUTION

– When using special threads, such as artificial

silk, you might want to turn the groove of the needle to the right in order to minimize the thread breaks.

8.2.4) Relationship between needle and hook

– Adjusting timing between needle and hook

Default timing of the needle and the hook is set by the main shaft angle of 201°. Relationship between the needle and the hook varies as below .

Top edge of the needle hole

Top point of hook circumference

Hook point

Top edge of the needle hole

Needle tip

Lower dead stop of the needle bar

Hook point

a. At lower dead stop of the needle bar 2.3~3.7 mm b. At needle-hook timing 1.8~2.2 mm c. At needle-hook timing 0.5~1.5 mm

If the needle is not inserted all the way to the top of the needle bar hole, timing of the machine will go off, causing broken needles and thread breaks.

CAUTION

Page 36

– Adjusting allowance in the hook

The hook can move right and left if there is an allowance in the lower shaft gear. Eliminate the allowance (gap) by turning the hook clockwise. Then adjust the timing.

8.2.5) Adjusting gap between needle and hook point

– Gap between the hook point and the needle

The distance between the needle and the hook should be 0.1-0.3mm at their closest interface.

– Thread skip

Thread skip occurs due to thread looping or inadequate balance or gap between the needle and the hook.

– Adjustment

The closer the hook point is to the needle, the hook point will be inside the loop and threading will be more stable.

Hook allowance (gap)

Hook point

0.1~0.3mm

8.2.6) Functions by needle shape

Hole and groove of the needle vary by the size and type of the needle. – Front groove

It protects the thread from the friction heat of the sewing (which can cause thread breaks).

– Back groove

It adjusts the hook timing according to the needle movement, thus preventing thread skips.

Back groove

Front groove

Needle eye

1) Prevention of looping is important for stitching. Adjust the hook point as close to the needle as possible to achieve the perfect thread position.

2) If embroidery state is not good, move the needle slightly to the right.

CAUTION

Page 37

8.2.7) Different loop shapes

Shape of the loop varies by the type of thread or fabric. Unstable shape of the loop may result in skipped stitches. The following pictures show different shapes of loop formed by different types of thread.

Synthetic thread loop

Cotton thread loop

Page 38

8.2.8) Relationship between the take-up lever and the hook

Hook point timing is directly related to thread tension and thread breaks. The following pictures show the location of hook when the take-up lever starts to move up from the lower dead stop (main shaft rotation angle: 291°).

Too small

Too large

1) Hook timing is fast (in the A range)

The hook starts to take the thread from the takeup lever. Loop is small because the upper thread is pulled. Stitches are made but stitch tension is bad. Thread skips occur, where hook fails to go through the loop.

2) Hook timing is slow (in the B range)

The hook starts to take the loop before the takeup lever goes up. Thread skips don’t occur, but thread breaks occur, because the take-up lever moves faster than the thread coming off the hook.

(A)

(C)

(B)

In normal hook timing, the hook should be in the (C) range.

NOTE

Page 39

8.3.2) Disassembling the thread detector

You will need to disassemble the thread-break detector unit when you to have to clean it for more smooth rotation. Remove the cover of the thread tension adjusting plate, separate the cables of the thread detection board, and unfasten the roller base bolts. The entire unit will be disassembled including the rollers and bush bearing.

8.3) THREAD DETECTOR ASSEMBLY AND FUNCTIONS

8.3.1) Functions of the thread detector

The thread detector prevents bad embroidery by detecting breaks of the upper or the lower threads. The thread detection roller performs the detection.

ADJUSTING MAJOR PARTS OF THE MACHINE

Turn OFF the main power when adjusting the machine.

CAUTION

Clean the machine regularly to prevent thread tails clouding around the lower thread holder. Such may undermine the function of the lower thread holder.

CAUTION

10.1) TRIMMER ADJUSTMENT

10.1.1) Moving Place Position Adjustment

– The proper position of the moving blade is that the cutting point of the fixed blade should be at the end of the

fixed blade. If the moving blade is not properly positioned, such problems as upper thread separation and cut skipping could occur.

– If the moving blade is not properly positioned, loosen the fixing screws for the moving blade links (A), (B)

and turn on the power. Then the trimming motor moves to the default point. Place the moving blade at the end of the fixed blade, and then tightly fasten the fixing screw .

10.2) ADJUSTING UPPER THREAD HOLDER

10.2.1) Adjusting

Unfasten the base bolts of the upper thread holder base. Press with your hand the connecting lever of the motor shaft and fix the base at a position where hook of the upper thread holder completely passes through the center of the needle. Unscrew the bracket bolt so the bracket does not load the upper thread holder. Fasten the bracket bolt where the upper thread holder operates smoothly .

10.2.2) Checking

After adjustment, check if the upper thread holder operates smoothly when the needle is changed, by changing the color.

10.3) ADJUSTING LOW-NOISE PRESSER FOOT

10.3.1) Setting the low-noise presser foot

Unfasten all screws of the presser foot cam and drive lever (s). Turn the hand pulley to the maximum lower position of the needle bar (180°). Turn the cam with the roller inserted to it. When the roller reaches a position,

where it aligns with the maximum eccentricity of the cam (roller is farthest from the arm in the picture), fasten the screws tightly .

10.4) RELA TIONSHIP BETWEEN PRESSER FOOT AND NEEDLE

10.4.1) Relationship between presser foot, needle, and embroidery fabric

For stable stitching, the presser foot must be pressing the embroidery material before the needle pierces into the material. The same is true for when the needle comes out of the material.

10.4.2) When the presser foot is too high

– Needle in

The picture shows the presser foot fails to press the work material when the needle pierces into the fabric, causing an unstable needlework.

– Needle out

The picture shows the presser foot fails to press the work material when the needle comes out of the fabric. The embroidery material is lifted up along with the needle, making a gap between the fabric and the needle plate. This may cause thread breaks, skipped stitches, or unstable stitching.

10.5) ADJUSTING HALF-TURN FILM

For automatic color change, if the needle is not at the center of the needle hole on the plate, adjust the half-turn film as below . – Adjusting the half-turn film

Adjust the cam position using a manual knob so the roller is on the center of the color change cam on the straight line when the needle aligns with the center of the needle hole on the needle plate. Make an adjustment so the center of the half-turn film aligns with the center of the half-turn sensor.

Color change cam

Half-turn film

1) Manual color change must be performed at the main shaft angle of 100°. Manual color

change at the main shaft angles other than 100°can cause damage on the controller and the take-up unit.

2) If you cannot align the needle to the center of the needle hole by adjusting the half-turn film, call your SWF dealership or a skilled engineer for help.

CAUTION

10.7) ADJUSTING JUMP SOLENOID

Solenoid adjustment is required for new or malfunctioning jump solenoids.

10.7.1) Adjusting the standby position (assembling solenoid and bracket)

10.7.2) Adjusting the assembly location (assembling solenoid-attached bracket to the arm)

– Unscrew solenoid nut using the jump solenoid

adjusting spanner and adjust so that the bracket and the solenoid operation surface are 3.5mm away . Fasten the nut.

– If the gap is too big, the needle bar controller

can interfere with the solenoid screw and therefore the needle bar can stop. If the gap is too small, the needle bar controller can hold the needle bar even during the jump, causing bad jumps.

– Adjust so that the processed surface of the arm

is 1mm from the bracket surface. Fix with the bracket screw .

– If the location is not good, the needle bar

controller can touch the needle bar during the jumps, making the needle bar work during the jumps.
