My limited first impression:
For the 25" bar, it's fairly difficult to stall the chain. The bar and saw combination is not weak by any means. One thing on the todo list was to go around cutting off the final rounds at ground level for half dozen white oaks. Each was 175-195 years old, 30"dia, and solid. A very strong cut, and made very quick work of it. Glad I waited for that job. Also, the weight is a little deceiving. I think the weight is around 13lb, but that's for the engine only. Add a solid bar, chain, fuel, oil, I could see getting a little tired at the end of the day with it vs a lighter saw. Maybe I'll be grabbing it more often, maybe not, we'll see. Lay it on some bigger rounds, that's seems to be where it needs to be. As far as running hot - I came back the next day to have a look in the woods and noticed one of the rounds was 3/4 burned and gone. A smaller saw can cause embers to form also, but I just thought it was funny, new saw, smokin rounds. One thing I need to get up to speed on is the m-tronic tuning. Does it do it on it's own?, or done at the start of a day - I'll find out but unsure at the moment.
