OPERATION
PROPER PROCEDURE FOR TREE FELLING
See Figure 30.
1.Pick your escape route (or routes in case the intended route is blocked). Clear the immediate area round the tree and make sure there are no obstructions in your planned path of retreat. Clear the path of safe retreat approximately 135° from the planned line of fall.
2.Consider the force and direction of the wind, the lean and balance of the tree and the location of large limbs. These things influence the direction in which the tree will fall. Do not try to fell a tree along a line different from its natural line of fall.
