dead branches which can fall while cut-
ting c ausing s erious injury. Do not cut
near b uildings or electrical wires if you
do notknow the direction oftree fall,nor
cut at night since you will not be able to
see well, nor during bad weather such
as rain,snow,or strongwinds,etc. Ifthe
tree doe s make contact with any utility
line, the utility company should be noti-

S The chain saw o perator should keep
on the uph ill side of the terrain as the
tree is likely to rollor slide downhilla f-
ter it is felled.
S Study t he natur al conditions that can
cause t he tree to fall ina par ticulardirec-
tion, such as:
S The wind direction and speed.
S The leanof the tree.The leanofatree
