3. When “FL ON” is selected without installing the auto-lifter device, starting is momentarily
delayed at the start of sewing. In addition, be sure to select “FL OFF” when the auto-lifter
is not installed since the touch-back switch may not work.

When the solenoid is used with the air drive setting, the solenoid may be burned out. So, do not
mistake the setting.
When the auto-lifter device (AK) is attached, this function makes the function of auto-lifter work.
