Before starting any cutting, you should first check for hornets nests and dead branches.
Clear away creepers.
You should cut from both sides of the tree.
Chop a notch on one side of the tree at a 45 degree angle.
Make a notch on the other side of the tree, but at a lower level.
The notch on the lower side is the direction you want the tree to fall.
Note that a tree with most of it`s branches on one side will fall that way.
When cutting, alternate the angle of strokes so as to prevent the axe from jamming.
