| The maximum sewing speed of 2,500 sti/min has been achieved by the adoption of an optimal machine structure for high-speed drive. The speed is significantly enhanced from the former 2,200 sti/min level. By enhancing the rigidity of the needle bar-area parts (patent pending) and having the feed mechanism and needle bar rotating mechanism servo-controlled, the operating time has been reduced, resulting in 13% reduction of the machine time compared with the conventional model. |  |
| With the highly-rigid feed mechanism with servo control, stitch point is very precise and feed drifting, which is specific to electronic sewing machines, does not occur even in high-speed sewing of weighty mate-rials. The servo control also makes home position de-tection unnecessary.The shape of the looper, the thread take-up amount and some other parts have been reviewed. Skipped stitches and insufficient thread tightening due to a change of thread tension are reduced, regardless of types of threads. The range of sewing capability has been enlarged. |  |
| The arm pocket of 120 mm depth gives a sufficient space, enabling material setting smooth. It is the most suitable for sewing of vertical buttonholes and hip pocket parts. The arm shape provides a good view of the needle area, allowing operators to observe the sewing operation. |  |
| With thorough review of the mechanisms causing noise, quieter sewing even at higher sewing speed than the conventional model has been realized. The machine is made with a sound design gentle to ears, eliminating impact noise. The vibration of the feed base which is transmitted to an operator is also reduced. The working environment with less operator fatigue can be materialized. |  |

| Main applications | Ladies wear | Men's wear, casual wear | Jeans | |
| Other applications | Only the upper thread is cut by the thread trimmer. Buttonholes up to 50 mm long can be sewn. | Ladies wear,jeans,trousers | ||
| Features | Only the upper thread is cut by the thread trimmer. Buttonholes up to 50 mm long can be sewn. |
All the threads are cut long by the thread trimmers. The long thread ends can be securely held in the subsequent process. It is suitable for cases that require accurate short end or manual trimming. |
All the threads are cut short by the thread trimmers. This saves the trouble of manual trimming and reduces consumption of the thread. |
