Summary:
Get the gear and then offer to help someone you know to be skilled and sensible for a few hours. ASK them for instruction and LISTEN.
Learn to tune the carb by ear and practice. Open the needle until it slows down and maybe smokes, then lean it down until it smooths out. Lean a little more and you'll see it lose power and die. DON"T run lean under load for any real time. The right setting is well rich, not far short of the point where it changes note. Again, get someone to show you this. With a good instructor, it's a five minute thing. If you ever learned to deal with model planes, you're nearly there already. When the mixture is right, the saw will hunker down and sing under cutting load. If it smokes or tries to die, it's wrong.
Get the right files and ASK for instruction. Bum blades will cause you to work unsafely AND eat up the WildThing quickly. When you and your instructor think you are off to a good start, you'll probably want a non safety chain, as mentioned before. At least you'll want to lower the rakers to allow your chain to get a good bite...Use the instructor's saw a little to get a feel for how a cut should feel. It should take very little effort to keep the chain throwing chips. If you find yourself trying to force the cut, it means something is wrong.
Oak and hickory trunks over a foot or so in diameter are a load for the WT. You should sharpen/tension the chain at least every time you fill up. Keep the chain out of the dirt. Flip the bar every few sharpenings.
Be putting money aside for a new bar and a couple of chains so they are not a hardship when needed.
Mix only a gallon of fuel and after a couple of months burn leftover in a lawnmower or some such (might be bad for a car cat converter). I put it in a tractor.
Start asking tree guys and friends for wood. You'll be surprised what will turn up, but resist the temptation to drop trees near houses until you have a LOT of experience!
I'm basically an educated hack, but I've survived 40 years of sawing, mostly with marginal equipment. Now I have two pretty good Stihls and one heavy old Timberbear that I use only for big trunks. You can do it and if you get started off right you'll love the heating process.
Obviously you have to have a mall and a couple of wedges, but be trying to make friends with someone who has a splitter. I have been on both sides of deals to share splitters in exchange for wood/help. When you get a bunch of wood ahead, renting makes sense, expecially if you go in with someone. Two people can split 3-4 times what one can. The smallest woman or kid can learn to work the valve for you in a few minutes, freeing stronger hands for lifting/loading.
If you have helpers, tell them in no uncertain terms NOT to get close, especially not to walk up behind you!
Good luck and let us hear about your progress. Oh yes, you are now cutting NEXT YEAR"S wood. Don't even think about burning anything green cut now! Small deadfalls maybe, but wood over 4" or so takes forever to dry if not split. Lots of it will rot before drying, if left outside.
Well, that got a little long. Hopefully you'll take it as encouragement to get going and work properly! Remember, the saw is probably as dangerous as a pistol if used carelessly and can kill or maim you or, worse yet, someone else.
