Where can I get spare parts for a Ryobi hedge trimmer?

My Ryobi RH600 should have 4 sets of locking nuts & bolts holding the blades together. Unfortunately one set appears to have worked loose & needs replacing.

I have oil and gas leakage on my two cycle Ryobi CS 30 weed eater.
Does it need a new gasket or O ring?
