We used the Stihl 009 for our firewood up Cape york, wonderful saw. The Huskies tend to be tempermental, but great once going.
The best advice i could give would be to wash the saw down once you've used it to cut anything green, acidic tree sap is a killer on the magnesium and that was the only issue we had. Never lend it to anyone, if they injure themselves, you'll be sleepless for weeks.
As much of a drama as it seems, ALWAYS use your safety gear, full face sheild, muffs and covers. Trust me on this, as i learned the hard way.
They are fun to use, and save alot of manual labour, as you've obviously worked out, but you can't be too cautious with a chainsaw!!!
Enjoy your new toy.
