Cutting instruction
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 approximate
-
ly 1/10 of diameter to the inner edge of the notch in order to
leave the uncut portion of the wood as a 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 di
-
rection.
When the tree starts to fall, stop the unit, place the saw on the
ground and make your retreat quickly.
