S Study the natural conditions that can cause
the tree to fall in a particular direction.
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. Useaplumborleveltode-

S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. Ifthetrunk isrotted,
it can snap and fall toward the operator.
Check for broken or dead branches which
can fall on you while cutting.
Make sure there is enough roomfor thetreeto
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.
