MF, this was mainly just an experiment to see if it would. I already have too many chainsaws - a Victa 16in which I bought new on clearance, and Ozito 10inch Arborist which I bought new on clearance, 2x Ryobi pole pruners bought new on clearance, plus an older Poulan Arborist saw.
I bemoan doing any inherently dirty work with any of them - this Ryobi's main jobs will be the crappy cutting of palm trees (which grow dirt up in them) stumps, and roots if required.
Keep it on a diet of 40:1, sharp chain, clean filters and run it until it dies
