Buy Felling Wedges
Two plastic felling wedges will prevent your saw from getting pinched during a cut. You can find these at any outdoor power equipment store that carries chain saws.
Estimate the Felling Zone
Clear a Cutting Zone
Even when you're sure which way the tree is going to fall, you're still not ready to fell it. Cut away any brush around the trunk and clear two escape routes on the “non-falling” side of the tree. They should be about 45 degrees away from each other in opposite directions. The last thing you want is to trip while walking away from a falling tree.
