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.
