The best thing you can do for you new Echo CS-800 is to run remove the limiter caps and custom tune from the first moment it sees use. Be just a tad rich vs lean with the "H" speed screw, it should be "four stroking" nicely at no load then smooth up as soon as it sees some load.
I would also mix 2 gallons of 92-93 octane fuel to one bottle of mix vs 2.5 gallons, and do this for the life of the saw.
I have a good many Echo saws in my line-up, and have set up scores of them for friends and customers and absolutely ZERO issues anyplace with any of them, even in commercial use. So I doubt if you'll need to worry much about the Warranty anyhow, provided you give the saw a fighting chance right out of the gate.......FWIW.....Cliff
