1. Remove hook driving shaft oil wick setscrew ❷ and attach hook driving shaft stopper screw
❸ (part number : 11079506) and rubber ring ❹ (part number : RO036080200).

2. Loosen oil amount adjustment screw ❶ up to the minimum so as to reduce the oil amount in

the hook. However, do not completely stop the oil and be careful not to allow oil adjustment
screw ❶ to come off.

3. Never drain the oil in the oil tank even when RP hook (hook for dry head) is used.

Bed

Oil splashes
conrmation paper

Closely t the paper against
the wall surface of the bed.

* Place the amount of oil (oil splashes) conrmation

paper under the hook and keep it from the hook by
3 to 10 mm to conrm the amount.

* In the case of measuring the oil quantity in the hook, measure it under the "Bobbin winding mode".

Refer to "3-3. Winding the bobbin thread [Bobbin winding mode]" p.18 for the bobbin winding

mode.

* When carrying out the procedure described below in 2), conrm the state that the needle thread

from the thread take-up lever to the needle and the bobbin thread are removed, the presser foot is

lifted and the slide plate is removed. At this time, take extreme caution not to allow your ngers to

come in contact with the hook.

1) If the machine has not been sufciently warmed up for operation, make the machine run idle for approxi-

mately three minutes. (Moderate intermittent operation)

2) Place the amount of oil (oil splashes) conrmation paper under the hook while the sewing machine is in

operation.

3) Conrm that oil exists in the oil tank.

4) Conrmation of the amount of oil should be completed in ve seconds. (Check the period of time with a

watch.)

3-12-3. Sample showing the appropriate amount of oil

Appropriate amount of oil (small) Appropriate amount of oil (large)

Splashes of oil from the hook

• DDL-9000C-FMS : 0.5 to 1 mm

• DDL-9000C-FSH : 1 to 3 mm

Splashes of oil from the hook

• DDL-9000C-FMS : 1 to 1.5 mm

• DDL-9000C-FSH : 2 to 4 mm

1) The state given in the gure above shows the appropriate amount of oil (oil splashes). It is necessary

to nely adjust the amount of oil in accordance with the sewing processes. However, do not excessively

increase/decrease the amount of oil in the hook. (If the amount of oil is too small, the hook will be seized

(the hook will be hot). If the amount of oil is too much, the sewing product may be stained with oil.)

2) Check the oil amount (oil splashes) three times (on the three sheets of paper), and adjust so that it should

not change.

and turn the post ❸ counterclockwise (in direction B), the stroke will be decreased.

(2) Adjusting the pressure of thread take-up spring ❶

1) Loosen setscrew ❷, and remove thread tension (asm.) ❺.

2) Loosen tension post setscrew ❹.

3) Turn tension post ❸ clockwise (in direction A), the pressure will be increased, and turn the post ❸ coun­terclockwise (in direction B), the pressure will be decreased.

* Standard state of the thread take-up spring ❶

The engraved marker line ❻ on the machine arm is almost aligned with the top of thread take-up spring. (It is

necessary to adjust in accordance with materials and processes.)

To check how the thread take-up spring works, draw out the needle thread in direction F after

having adjusted the thread take-up spring pressure to check whether the thread take-up spring
exerts force to the thread up to the last moment (state G) just before the thread comes out
from E. If the spring fails to exert force to the spring until the last moment (state H), decrease

the thread take-up spring pressure. In addition, the stroke of the thread take-up spring is

excessively small, the spring does not work properly. For the general fabrics, a stroke of 10 to

13 mm is proper.

(3) Adjusting the thread take-up stroke

1) When sewing heavy-weight materials, move thread guide ❽ to the left (in direction C) to increase the

length of thread pulled out by the thread take-up.

2) When sewing light-weight materials, move thread guide ❽ to the right (in direction D) to decrease the

length of thread pulled out by the thread take-up.

* Standard state of the thread guide

• DDL-9000C-FMS : Marker line ❾ on the thread guide aligns with the center of the setscrew.

• DDL-9000C-FSH : Marker line ❾ on the thread guide aligns with the center of the marker line on the ma-

chine arm.

If the condensation pitch is decreased, the phenomenon where the needle enters the same

needle entry point will likely to occur, resulting in unstable formation of thread loop at the time

of thread trimming. As a result, thread trimming fault is likely to occur. It is therefore necessary

to adjust the condensation pitch carefully. (The needle entry phenomenon differs according to

the material to be sewn and the needle count, the pitch should be increased if thread trimming

failure occurs.)

The needle thread presser device is able to tuck the

needle thread on the wrong side of material as in the

case of the conventional wiper device.

[Feature]

• So-called "bird's nest phenomenon" which appears

on the wrong side of material can be reduced by
using needle thread presser device ① in combina-

tion with condensation stitching.

• Operability around the needle entry point is im-

proved.

• Applicability of various kinds of attachments de-

signed for use around the needle entry point is

improved.

[Adjusting the remaining length of needle thread]

Adjust the length of needle thread remaining at the

needle to 35 to 45 mm (for both the S and H types)
by turning thread tension No. 1 nut ②.

1) Turn thread tension No. 1 nut ② clockwise (in direc­tion A), to shorten the thread length remaining on

the needle after thread trimming or counterclockwise
(in direction B), to lengthen the thread length.

So-called "bird's nest phenomenon" is
reduced by shortening the length of needle
thread remaining at the needle. In this case,
however, the needle thread is likely to slip
off the needle eyelet. To reduce slip-off
of the needle thread, sewing speed at the
beginning of sewing should be reduced.

In the case any of the aforementioned problems occurs, the assist function which reduces the presser foot

pressure at the beginning sewing can be set by using the active presser lifting device.

* In the case the assist function is not used, adjustment should be carried out to allow the needle thread

placed between the presser foot and the material to smoothly come out from between them by decreasing

the presser foot pressure. (The recommended presser foot pressure is 30 N (3 kg) or less.)

Adjust the presser foot pressure and the sewing speed appropriately to prevent insufcient feed efciency

due to jumping or other faults of the presser foot. Conrm the adjustment result by actually sewing the ma-

terial.

[How to set the active-presser assist func-

tion]

1) Enter the presser foot lift setting time with

"U290".

2)

Press ❶ to conrm the entered value.

1. The amount of uplift of the presser foot above the throat plate varies according to the

material thickness of the item to be sewn and the presser foot pressure. Be sure to check

the actual condition before starting sewing.

2. If the adjustment value of the operating time of the AK-154 is increased while the presser

foot pressure is high, the operating noise will become larger. Adjust the adjustment value of

the operating time of the AK-154 and the pressure foot pressure while visually checking the

needle thread.

7-3-1. For checking of the thread trimming cam

timing

The purpose of the adjustment of the thread trim­ming cam is to align marker line A on pulley cover
❺ with green marker dot B (H type : White marker
dot B´) on handwheel ❻.

1) Tilt the sewing machine head.

2) Turn handwheel ❻ by hand in the normal direc-

tion of rotation until the thread take-up lever goes
up slightly below the upper dead point. Press cam
follower ❶ with ngers to the left (in direction of
arrow E) to t roller ❷ to in groove C in thread
trimming cam ❸.

3) In this state, turn handwheel ❻ in the direction

which is opposite to the normal direction of rota­tion until handwheel ❻ will go no further. (If the
handwheel is turned further, it reaches the posi­tion at which cam follower ❶ starts moving.)

At this time, marker line A on pulley cover ❺

aligns with green marker dot B on handwheel ❻.

7-3-2. Adjustment of the thread trimming cam

timing

1) Tilt the sewing machine head.

2) Loosen the screws No. 2 and No. 1 of thread

trimming cam setscrew ❼ in the written order.

3) Align marker line A on pulley cover ❺ with green
marker dot B (H type : White marker dot B´) on
handwheel ❻.

4) Pressing cam follower ❶ to the left (in the direc­tion of arrow E), engage thread trimming cam ❸
with roller ❷. Then, turn only thread trimming cam

❸ with ngers in the direction which is opposite

to the normal direction of rotation of feed driving
shaft ❹ until it will go no further without turning
feed driving shaft ❹. At this position, tighten the
screws No. 1 and No. 2 of thread trimming cam
setscrew ❼ in the written order while pressing
thread trimming cam ❸ against roller ❷.

1. In the case of using a high-count
lament thread, thread loop
formation may be unstable. If faulty
loop spreading occurs in this state,
correct the thread trimming cam
timing by aligning the marker line on
the pulley cover with the red marker
dot, instead of the green marker dot,
on the handwheel.

2. The alignment point between thread
trimming cam ❸ and roller ❷ is
position (F) from which cam follower
❶ starts moving. Position (G) at
which you feel that thread trimming
cam ❸ comes in contact with roller ❷
for the rst time during adjustment is
not the correct alignment position.

*

Be sure to correct the thread trimming
cam timing carefully since it largely
affects the loop spreading timing.

7-3-5. Adjustment of thread trimming speed

The thread trimming speed has been adjusted to 300 sti/min (H type : 220 sti/min) at the time of shipment.

This means that the high-speed thread trimming has been selected.

Depending on the type of thread to be used, the thread trimming speed should be increased. On the other

hand, in the case of using fragile thread (such as a high-count lament type thread or cotton thread), the

thread trimming speed should be decreased to reduce damage to the thread.

Thread trimming speed should be adjusted when appropriate according to the sewing process.

state by hand.

3) In this state, the standard adjustment value of the

clearance between picker link ❸ and picker arm
❹ is 0.5 mm. At this time, a clearance of 0 to 0.3
mm is provided between bobbin ❺ and picker ❻.

7-4-2. Standard adjustment

1) Loosen picker link pin nut ❷ (9 mm). Carry out adjustment by moving picker link ❸ to the right and left.

2) After the adjustment, tighten picker link pin nut ❷.

7-4-3. Standard adjustment (Adjustment at the tip position)

1) Loosen picker setscrews ❼ (two pieces). Adjust the position of picker.

2) After the adjustment, tighten picker setscrews ❼ (two pieces).

1. If there is no clearance between bobbin ❺ and the tip of picker ❻, picker ❻ strongly press
bobbin ❺. As a result, the bobbin fails to supply a required length of bobbin thread at the

time of thread trimming. In this case, the bobbin thread is likely to be trimmed short and

thread slip-off at the beginning of sewing is likely to occur.

2.

If there is an excessively large clearance between bobbin ❺ and the tip of picker ❻, thread

required for thread trimming may slip off the tip of picker and the length of needle thread
remaining at the needle tip after thread trimming will be short. In addition, bobbin ❺ is likely

to idle frequently at the time of thread trimming causing problems at the beginning of sewing.

7-5. Active-presser multi-layered section detection function

7-5-1. Multi-layered section detection function

This function allows detection of a multi-layered section of material. When a multi-layered section of material
is detected, the sewing parameter is automatically changed to the one-touch changeover parameter ("4-2-

9. One-touch utility changeover function" p.50) to allow the sewing machine to continue sewing. The

multi-layered section detection setting can be stored in memory on a pattern-by-pattern basis.
Detectable material thickness : Max. 10 mm
Detection resolution : 0.1 mm

* Multi-layered section of material that is less than 2 mm in thickness is likely to be affected by the feed dog

height. Stable detection, therefore, cannot be carried out. It is not possible to detect two or more multi-lay­ered sections thickness of which are different. In this case, the one-touch changeover function by means
of the hand switch should be used.

* The multi-layered section detection function is disabled while the one-touch changeover function by

means of the hand switch is carried out.

7-5-2. Multi-layered-section detection number of stitches setting function

In the case the multi-layered section detection is enabled, the sewing parameter is automatically returned to
the setting for the normal section of material if the material thickness becomes smaller than the "threshold".
However, the sewing-parameter changeover timing can be changed by setting the multi-layered-section
detection number of stitches. Once the multi-layered-section detection number of stitches is set, the thresh­old returns to the value for the normal section of material when the aforementioned set number of stitches
is reached after the detection of a multi-layered section of material, even if the sewing is started from the
multi-layered section. It should be noted, however, that the sewing parameter returns to the one for the
normal section of material if the material thickness falls below the "threshold" for the multi-layered section
detection, even within the range of the set multi-layered-section detection number of stitches.
