How to Open Ryobi 31 CC Weed Wacker String Attachment

Ryobi 30CC and 31CC weed whackers are dependable and versatile pieces of yard equipment. Most of their line has the option of attaching a brush cutting blade as well as the standard string attachment. As with all string trimmers, the string requires replacement from time to time. There is also the inevitable knot inside that prevents the string from advancing when you hit the bump knob. Replacing the string or removing tangles requires opening the Ryobi 31CC weed whacker string attachment.
