Ryobi RBC30SET Strimmer/Brushcutter

[gulliver1]

How do you attach the Pro Cut 11 Line head to the drive shaft, the one where you put the pre-cut lengths of trimmer line into, its brand and I think I might have a part missing, has anyone got a Ryobi touch start that can help me.

Don't know that one, but there is usually a hex shaft, or adapter nut that screws to the drive outlet at the head.
