How do I restring a Ryobi Expand-It weed eater?

To restring a Ryobi Expand-It weed eater, first remove the spool from the trimmer head. Cut a length of new trimmer line, usually around 10 feet. Insert the line into the spool following the arrows for the correct winding direction. Secure the line in the notches on the spool and reassemble the spool onto the trimmer head.
