TREE FELL ING TECHNIQUES
WARNING: Felling a tree requires
chain saw skills and experience. Inexperi-
enced users shouldnot felltrees. Do not at-
tempt any task that makes you feel uncom-
fortable or unsure.
WARNING:Donotcut nearbuildings
or electrical wires if you do not know the di-
rection of tree fall, at night since you will not
be able to see well, or during bad weather
suchas rain, snow,or strongwinds.as fall is
unpredictable.
Carefully plan your sawing operation in ad-
vance. You need a clear area all around the
tree soyoucan have secure footing. Check
for broken or dead branches which can fall
on you causing serious injury.
