ends, sewing stops and the sewing speed becomes the start backtacking

(constant) speed

 

 

 

1: When the treadle is returned to the neutral position, start backtacking can

 

 

 

be stopped before it is finished, and the speed during start backtacking

 

 

 

becomes the speed corresponding to the treadle depression amount (low

 

 

 

speed - start backtacking speed)
