Directional cuts
To make the directional cut you begin with the top cut. Aim 
using to the saw’s felling direction mark (1) toward a goal 
further forward in the terrain, where you would like the tree 
to fall (2). Stand on the right-hand side of the tree, behind 
the saw, and cut with a pull stroke.
Next make the bottom cut so that it finishes exactly at the 
end of the top cut.
The directional cuts should run 1/4 of the diameter 
through the trunk and the angle between the top cut and 
bottom cut should be 45
°
.
The line where the two cuts meet is called the directional 
cut line. This line should be perfectly horizontal and at 
right angles (90
°
) to the chosen felling direction.
Felling cut
The felling cut is made from the opposite side of the tree 
and it must be perfectly horizontal. Stand on the left side 
of the tree and cut on the pull stroke.
Make the felling cut about 1.5-2 inches (3-5 cm) above the 
bottom directional cut.
Finish the felling cut parallel with the directional cut line so 
that the distance between them is at least 1/10 of the 
trunk diameter. The uncut section of the trunk is called the 
felling hinge.
The felling hinge controls the direction that the tree falls in.
All control over the felling direction is lost if the felling 
hinge is too narrow or non-existent, or if the directional 
cuts and felling cut are badly placed.
When the felling cut and directional cut are complete the 
tree should start to fall by itself or with the aid of a felling 
wedge or breaking bar.
We recommend that you use a bar that is longer than the 
diameter of the tree, so that you can make the felling cut 
and directional cuts with single cutting strokes. See 
instructions under the heading Technical data section to 
find out which lengths of bar are recommended for your 
saw.
There are methods for felling trees with a diameter larger 
than the bar length. However these methods involve a
