Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
slopingterrain. Useaplumb or level tode-
termine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.

Check for broken or dead branches which
can fall on you while cutting.
Make sure there is enough room for the treeto
fall. Maintain a distance of 2-1/2 tree lengths
from the nearest person or other objects. En-
gine noise can drown out a warning call.
