Cutting instruction
Begin the cut on the side to which the tree is to fall.
Notch: 1/3 of diameter and 30
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.
Fell big tree.
To fell big trees with a diameter exceeding twice the bar
length, start the notching cuts from one side and draw the saw
through to the other side of the notch.
Start the back cut on one side of the tree with the spiked bump-
er engaged, pivoting the saw through to form the desired hinge
on that side.
Then remove the saw for the second cut.
Insert the saw in the first cut very carefully so as not to cause
kickback.
The final cut is made by drawing the saw forward in the cut to
reach the hinge.
