I love my 084, although I rarely use it. I bought it for quartering large logs to fit on my band saw mill. I fired it up over the weekend for the first time in a couple years, and it started in just a couple pulls. I split a 20" south TX mesquite in a few seconds, like it was butter. The log was just under 4' long so it wouldn't quite fit on the mill bunks. Splitting it allowed me to screw a board to the flat and make it fit the mill. Until then, the last time I used it was quartering a nearly 3' diameter white oak log. Took just a few minutes to split the giant into 4 pie shaped logs. I can't speak to maintenance or issues, as I have never had to do anything but sharpoen the chain & keep the saw topped with oil & fuel. It's a dependable workhorse for me.
