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-
termine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted, 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
room for the tree to fall. Maintain a distance of
2-1/2 tree lengths from the nearest person or
other objects. Engine noise can drown out a
warning call. Remove dirt, stones, loose bark,
nails, staples, and wire from the tree where
