To make the directional cuts
1. Start to make the directional cuts by making the top
cut first. Aim with the chainsaw'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 chainsaw, and
cut with a pull stroke.
2. Make the bottom cut so that it finishes exactly at the
end of the top cut.
1
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.
To make the 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.
1. Make the felling cut about 3-5 cm/1.5-2 inches above
the bottom directional cut.

2. 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.
WARNING: 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.
3. When the felling cut and directional cuts are
complete the tree should start to fall by itself or with
the aid of a felling wedge or breaking bar.
WARNING: 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
Accessories on page 38 to find out which
lengths of bar are recommended for your
chainsaw.
