3) Deletion of Thread-Break Detection Function
Poor function of the thread detecting roller due to foreign substances around it may result in wrong and frequent
detections, causing inefficiency of work. In this case, you can turn off the detecting function by turning off the
toggle switch at the end of the thread tension adjustment board. This will turn off the detecting function on the
head you are working with.

As illustrated in [Fig.5-2], the needle bar will not move when you pull the jump clutch lever. Push the level to the

The trimmer and the take-up lever continue to move even when the needle bar is

thread.
Long-time operation of the needle bar with the clutch may damage the bar controller.
