4. Product overview ･The new model 1-needle lockstitch machine with automatic thread trimmer is based on the DDL8700-7 and comes with a direct-drive motor. In addition, its control box and operation panel are built intothe machine head motor cover.

5. Feature -1 ●Enhanced energy saving is achieved. By the adoption of the newly-designed motor and the new model control box, the new model sewing machine contributes to further reduced power consumption as compared with the conventional model. DDL5550-7 DDL8700-7 DDL8700A SBT/EBT＝onA/B/C/D＝4stitch TRM＝onFL＝offWP＝offPitch＝3 JUKI Power is saved by 25 % as compared with the DDL8700-7 (SC-920). ☆High-efficiency compact direct-drive motor ☆Further reduction of energy is achieved by adopting the new model control box and the energy saving mode.

6. ●Feature - 2 ① The thread trimming speed is 300 sti/min. This is the highest speed among the sewing machines of this class. ② Separate packing of the control box and the motor is not required. The whole machine head can be packed in one package. This contributes to reduced logistics cost and inventory cost.●  The machine head, control box and operation panel are packed in one package, thereby reducing the volume of packaging by 0.06593 m3. Number of units of machines that can be containerized into a 40-foot container DDL8700-7: 380 unitsDDL8700A-7: 580 units

7. ●Feature - 3 ● The direct drive motor is adopted, and the control and operation panel are integrated with the machine head motor. This contributes to easier setup of the machine. ● Waste material such as container boxes and styrene foam used for packing is reduced, thereby reducing waste material processing cost. This means the machine achieves eco-friendliness. ● Adoption of the direct drive motor which provides improved responsiveness helps reduce operator fatigue and achieves a comfortable usage environment.

8. ●Feature - 4 ●The machine-head built-in bobbin winder is adopted to achieve ease of operation. In addition, this bobbin winder helps prevent the operator from forgetting bobbin winding.

9. ●Feature - 5 ● An operation panel which has functions equivalent to those of the CP18 is provided as standard.(CP180D, IT10 and IT100 are available as optional parts and can be retrofitted.)

10. ●Feature - 6 ● In the case where the CP180D, IT10 or IT100 is retrofitted to the machine as an option: The switches on the operation panel provided as standard can be used for other functions. Seven different functions can be selected from the 22 different ones and can be assigned to the keys on the operation panel provided as standard.

11. ●Feature - 7 ● Auto-lifter (AK-85) is provided as an optional device which is same as Auto-lifter of DDL8700-7.

12. ●Feature - 8 The quantity of oil to be retained in the oil pan has been reduced. (The quantity of oil has been reduced by 25 % as compared with the DDL-8700-7. This means that the quantity of waste oil is reduced.) The oil pan is changed shape to flat. This flat-shaped oil pan is adopted in order to reduce the machine head package size. ① Shape of the oil pan has been changed to reduce the quantity of oil retained in the oil pan. ② The size of the oil pan has been reduced so as to reduce the machine head package size and has been fitted with a handle for easier oiling.

13. DDL-8700-7 ●Table ●  The table is exclusive to the DDL8700A-7. ・The bobbin holder (with a tapped hole) has been eliminated since it was located under the motor cover. ・ The motor mounting holes (three locations) have been eliminated and pedal sensor mounting holes (two locations) have been added. ・ The belt hole has been eliminated and a hole through which the power cord and the pedal sensor cord are passed has been added. ・A hole for the control box cooling fan has been added.

14. ● LED light (optional) Feature ① Longitudinal position adjustment The LED light is installed at its reference position by means of a double nut system. (See the illustration.) 1 to 3 mm: To be fixed with a washer placed between the nuts. 3.2 mm to the max. advancing mount of 7 mm: To be adjusted by means of two nuts with a nut placed between them.

15. ● LED light (optional) Feature ② Adjustment of the irradiation angle of the LED light The LED_BASE on which the LED PWB is installed can be turned. The LED light irradiation angle can be changed by fixing it at the desired angle

16. ● LED light (optional) Feature ③ Mounting location of the LED light can be selected. The LED light can be mounted on either the right or left side of the needle bar by changing the mounting location of the LED_BASE_SUPPORT. Therefore, the operator may select and change the mounting location of the LED light as desired. In addition, the illuminance is adjustable from a 0 to 100 level (%).

17. ●Sub-class of DDL8700A-7 We provide 2-class of sub-class which depend on production item and materials. 1. DDL8700AS7WBN : Standard machines 2. DDL8700AH7WBN : For heavy weight materials
