Just an FYI, for all those experiencing this - Ryobi has an unannounced (for this model anyway) recall on these units, should the fan blade fail. It WILL take a MONTH to get it replaced, but they will do it. It was offered to me - just yesterday, however by the time they responded to my inquiry about it (going on 3 weeks), I had already repaired my Ryobi P2108 blower. BTW - While I had it apart, I also replaced the bushing (Part No. 612854001) behind the broken fan blade (Part No. 529437004), Both on the parts list that is provided with the manual, which can be downloaded from the internet. The bushing was loose and worn, which probably was at least partially responsible for the failure of the fan blade..
