S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
S The bumper spike may be used as a pivot
when making a cut.
S Stop the saw if the chain strikes a foreign
object. Inspectthesaw andrepair partsas

sawing operation.

TREE FELLING TECHNIQUES
WARNING:Donotcutnearbuildings
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
such as rain, snow, or strong winds.as fallis
unpredictable.
Carefully plan your sawing operation in ad-
vance. You need a clear area all around the
tree so you can have secure footing. Check
for broken or dead branches which can fall
on you causing serious injury.
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. Useaplumb or level tode-
termine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If thetrunk is rotted,
it can snap and fall toward the operator.
Make sure there is enough room for the treeto
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.
