Does anyone know what the CFM is on the 580 (LB 4800) when the thumb dial is at the highest setting? I do know that when using the thumb dials lowest setting the CFM is 225. Also when the turbo button is depressed of course the CFM is the full 580.
I have been wondering the same thing and even called support to see if they knew. Unfortunately, they didn't have an answer either, but the CFM rating is listed for the 600 CFM back pack blower and I imagine that the 580 CFM blower would fall somewhere in between.
