Holy cow, what a beast of a chainsaw.
I don't know much about chainsaws myself, but my dad and grandad are huge fan of woodworking and also chainsaws.
When I get home from my school session I will show them this video (and translate a bit, since they don't understand english perfectly).
My dad bought a brand new chainsaw which is very powerful aswell, but not nearly as powerful and big as the one you got xD, but he is very proud of it.
This is quite big and my back won't love me .luckily I don't use it that often only for big logs.
