HAHAHAHAHA AWESOME! Same one I have......
My only tip is run high quality oil in the mix.....my dealer said he had several crews start to use them and they were running their Stihl mix through the Husqys and the engines were burning up as they run much hotter than a lot of the other units. He wasn't selling me oil as he said use anything rated equal to the Husqy mix and I would be fine.
Enjoy it! It is a beast!
Make the extra $ back by blowing some other yards around you if you have to.
