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

S Practice cutting a few small logs using the
following techniques to get the“feel” ofus-
ing your saw before you begin a major
sawing operation.
Natural conditions that can cause a tree to
fall in a particular direction include:
S Squeeze the throttle trigger and allow
theenginetoreachfullspeedbeforecut-
ting.
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 Begincuttingwiththesaw frameagainst

S Keep the engine at full speed the entire
time you are cutting.
S
Weight and branches on one side.
S Surrounding trees and obstacles.
S Allow the chain to cut for you. Exert only

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
