Hesston 5580

Just bought a hesston 5580 everything appears to be in good shape. I've got the manual and read it over. Greased everything etc. Just wondering if anyone who has experience with one of these balers has any helpful tips. I wont be baling a ton of hay with this thing. Will still be mostly square baling. Just wanted a rounder to get hay up in case of rain etc. I have no prior experience running a round Baler. So any helpful tips you can give me to keep me from learning the hard way would be much appreciated.
