Actually, I Think Husky owns/builds poulan. But I'm not 100% sure either. Stihl's home owner quality saws are still better than any poulan, or any other saw available at home depot, lowes, sears, etc,etc. And if they are not (makita fans are going to bite my head off), at least you know that stihl is not embarassed about the saw since they don't paint it a different color, and strike a deal with walmart to buy them by the thousands. stihl's home owner line is still only sold at stihl dealers, that says something i think. (Actually, stihls are going to be sold at most any john deere dealer soon, and we might see a green and yellow stihl someday, so I might have to eat my words).
Any ways, Congrats on the new purchase, I'll give a some advise for a first time saw owner.
Clean the air filter after the end of each day of use.
Keep the chain sharp and tensioned correctly, lots of info on here about chain sharpening, and I think stihl has good info on it in the owners manual.
Use 89 octain fuel if its cold enough to need a jacket while you work, and 91 if its not, or use 91 all the time, but don't run 89 octain on 90 degree days
Use only stihl brand 2 stroke mix, or husky, but thats usually hard to get at the stihl dealer. Also, Stihl bar oil. Yes good bar oil makes a difference.
If you might not use the saw for a couple months, empty the tank, then start the saw, and let it idle dry (never throttle hard on it while doing this, it will reduce the life of the saw a lot)
If you might not use the saw for months, like 6 months is a good mark, also, pull the spark plug, and put about a tea spoon of your 2stroke mix oil in the spark plug hole, pull the rope a few times slow, then put the plug back in.
THIS IS REALY IMPORTANT!, and lots of new saw owners seem to make this mistake alot.. If you notice that you don't have the HP that you normally have, the saw starts bogging out in a cut, STOP, and figure out why. Saws never (ok, all most never) start running so rich that they loose lots of power in the cut. 99% of the time they are to lean. there is a lot of reasons why a saw can run lean, DON'T force your saw to work in this condition.
