Felling a 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 hit-
ting 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 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.
Notch: 1/3 of diameter and 30
o
to 45
o
angle
Back cut: 2.5 to 5 cm higher
Uncut hinge wood: 1/10 of diameter
Cut a notch approximately 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.
Make the felling cut by placing spiked bumper 2.5 cm to 5 cm above the bottom of the notch
and stop cutting at approximately 1/10 of diameter to the inner edge of the notch in order to
leave the uncut portion of the wood as a hinge.

A: Leave 1/10 of diameter hinge
Do not try to cut through to the notch with the felling cut.
The remaining wood between the notch cut and felling cut will act as a hinge when the tree
falls, guiding it in the desired direction.
When the tree starts to fall, stop the engine, place the saw on the ground and make your retreat
quickly.
