5.2 Using the Presser Foot Pivot Function
Activate this function via the machine's settings. When enabled, the presser foot will automatically lift slightly when the machine stops with the needle in the down position, allowing you to easily pivot your fabric for precise corners and curves.
5.3 Engaging Free Motion Sewing
To engage free motion, lower the feed dogs using the lever located on the back or side of the machine. Attach a free motion quilting foot. Adjust the presser foot height if necessary for optimal fabric movement. This allows you to move the fabric freely to create custom designs.
