Ryobi: I have the older blue 18 volt chainsaw. It's excellent for clearing the punky downed apple trees in the orchard, 99% of its use here, but it's working hard in larger hardwood such as Eucalyptus. Think of it as a pruning saw, not a firewood saw.
And it leaks oil. The oiler is a rubber bulb on the fill cap and that soon tore. I replaced that, thinking that's where the oil escaped in storage, but no. So I store it nose down in its plastic sheath, carried in a plastic bucket. When cutting, oil the bar frequently with a squeeze bottle (like restaurant mustard).
Poison Oak: Yes the pole saw, or loppers. I've read the oils are in all parts including roots, and stay toxic for years, so even dry dead wood can get you. Don't burn or chainsaw it! I wear knee high rubber 'milking boots' when I can't avoid going into it.
