There is a delay from the time the thread nipper is turned OFF to the time the presser foot lifter is turned ON when toggle switch SW3 is set to ON and the thread nipper function is activated. There is a delay from the time the thread trimmer is turned OFF to the time the presser foot lifter is turned ON when toggle switch SW3 is set to OFF and the thread nipper function is deactivated. ON time of automatic presser foor lifter The presser foot will be automatically turned OFF after the set time passes. When the data is set to 00, the presser foot is not automatically turned OFF. There is a delay from the time the thread trimmer stops to the time the thread wiper is turned ON.
