Felling the Tree
A falling tree can seriously damage anything it may hit - a car, a
house, a fence, a power line, or another tree. There are ways to
make a tree fall where you want it, so first decide where that is!
Before cutting, clear the area
around the tree. You will need good
footing while working and you
should be able to work the saw
without hitting any obstacles. Next,
select a path of retreat. When the
tree begins to fall you should retreat
away from the direction of fall at a
45-degree angle and at least 3 m
(10 feet) from the trunk to avoid the
trunk kicking back over the stump.
Begin the cut on the side to
which the tree is to fall. Cut a
notch about 1/3 of the way into
the tree. The position of this
notch is important since the
tree will try to fall “into” the
notch. The felling cut is made
on the side opposite the notch
and at a level about 5 cm
(2 in.) above the bottom of the
notch. Do not try to cut through
to the notch with the felling cut.
The remaining wood between
the notch cut and felling cut
about 5 cm (2 in.) will act as a
hinge when the tree falls,
guiding it in the desired
direction. When the tree starts to fall, kill the engine, place the saw on the
ground and make your retreat quickly.
