3. PREPARATION BEFORE SEWING

3-1. Attaching the needle

WARNING :

Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine.

		D	B
		C	A

Use the specified needle for the machine. Use the proper needle in accordance with the thickness of thread used and the kinds of the materials.

1)Turn the handwheel until the needle bar reaches the highest point of its stroke.

2)Loosen screw , and hold needle with its indented part A facing exactly to the right in direction B.

3)Insert the needle fully into the hole in the needle bar in the direction of the arrow until the end of hole is reached.

4)Securely tighten screw .

5)Check that long groove C of the needle is facing exactly to the left in direction D.

When polyester filament thread is used, if the indented part of the needle is tilted toward operator's side, the loop of thread becomes unstable. As a result, hangnail of thread or thread breakage may occur. For the thread that such phenomenon is likely to occur, it is effective to attach the needle with its indented part slightly slanting on the rear side.

3-2. Removing/fitting the bobbin case

WARNING :

Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine.

			1)	Turn the handwheel to lift the needle above the
				throat plate.
		2)		Install the bobbin in the bobbin case so that the
				thread wound direction is clockwise.
		3)		Pass the thread through thread slit A of the bob-
		A		bin case, and pull the thread in direction C. By
				so doing, the thread will pass under the tension
				spring and come out from notch B.
		4)		Check that the bobbin rotates in the direction of
	B			the arrow when thread is pulled.
		5)		Pinching latch D of the bobbin case with fingers,
				fit the bobbin case in the hook.

1)Insert the bobbin deep into the bobbin winder spindle until it will go no further.

2)Pass the bobbin thread pulled out from the spool rested on the right side of the thread stand following the order as shown in the figure on the left. Then, wind clockwise the end of the bobbin thread on the bobbin several times. (In case of the aluminum bobbin, after winding clockwise the end of the bobbin thread, wind counterclockwise the thread coming from the bobbin thread tension several times to wind the bobbin thread with ease.)

3)Press the bobbin winding lever in the direction of A and start the sewing machine. The bobbin rotates in the direction of B and the bobbin thread is wound up. The bobbin winder spindle automatically as soon as the winding is finished.

4)Remove the bobbin and cut the bobbin thread with the thread cut retainer .

5)When adjusting the winding amount of the bobbin thread, loosen setscrew and move bobbin winding lever to the direction of C or D. Then tighten setscrew .

To the direction of C : Decrease To the direction of D : Increase

6)In case that the bobbin thread is not wound evenly on the bobbin, remove the handwheel, loosen screw and adjust the height of bobbin thread tension .

•It is the standard that the center of the bobbin is as high as the center of thread tension disk .

•Adjust the position of thread tension disk to the direction of E when the winding amount of the bobbin thread on the lower part of the bobbin is excessive and to the direction F when the winding amount of the bobbin thread on the upper part of the bobbin is excessive.

After the adjustment, tighten screw .

7)To adjust the tension of the bobbin winder, turn the thread tension nut .

1.When winding the bobbin thread, start the winding in the state that the thread between the bobbin and thread tension disk is tense.

2.When winding the bobbin thread in the state that sewing is not performed, remove the needle thread from the thread path of thread take-up and remove the bobbin from the hook.

3.There is the possibility that the thread pulled out from the thread stand is loosened due to the influence (direction) of the wind and may be entangled in the handwheel. Be careful of the direction of the wind.

3-12. Adjusting the amount of oil (oil splashes) in the hook

WARNING :

Be extremely careful about the operation of the machine since the amount of oil has to be checked by turning the hook at a high speed.

3-12-1. Adjusting the amount of oil in the hook

Decrease	Increase

Tighten (turn clockwise) oil amount adjustment screw to increase the amount of oil in the hook, or loosen (turn counterclockwise) to decrease it.

[When using RP hook (hook for dry head) for DDL-9000C-SMS type]

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

2.Loosen oil amount adjustment screw 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 to come off.

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

– 23 –

3-12-2. How to confirm the amount of oil (oil splashes)

Amount of oil (oil splashes) confirmation paper

Approx. 25 mm

Approx. 70 mm

* Use any paper available regardless of the material.

Position to confirm the amount of oil (oil splashes)

Hook	Hook driving shaft front bushing

3 to 10 mm

Bed

Oil splashes confirmation paper

Closely fit the paper against the wall surface of the bed.

* Place the amount of oil (oil splashes) confirmation paper under the hook and keep it from the hook by 3 to 10 mm to confirm the amount.

*When carrying out the procedure described below in 2), confirm 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 fingers to come in contact with the hook.

1)If the machine has not been sufficiently warmed up for operation, make the machine run idle for approximately three minutes. (Moderate intermittent operation)

2)Place the amount of oil (oil splashes) confirmation paper under the hook while the sewing machine is in operation.

3)Confirm that oil exists in the oil tank.

4)Confirmation of the amount of oil should be completed in five 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	Splashes of oil from the hook

• DDL-9000C-SMS : 0.5 to 1 mm						• DDL-9000C-SMS : 1 to 1.5 mm
• DDL-9000C-SSH : 1 to 3 mm						• DDL-9000C-SSH : 2 to 4 mm

1)The state given in the figure above shows the appropriate amount of oil (oil splashes). It is necessary to finely 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.

				C D
F		E	A		A
			B		B
	GH

(1)Adjusting the stroke of thread take-up spring

1) Loosen setscrew .

2) Turn tension post clockwise (in direction A), the stroke of the thread take-up spring will be increased, and turn the post counterclockwise (in direction B), the stroke will be decreased.

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

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

2)Loosen tension post setscrew .

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

* Standard state of the thread take-up spring

The engraved marker line 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 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 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-SMS : Marker line on the thread guide aligns with the center of the setscrew.

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

chine arm.
