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. Set the spiked bumper (if one is fitted) just behind
the felling hinge.
3. Use full throttle and advance the saw chain/guide
bar slowly into the tree. Make sure that the tree does
not start to move in the opposite direction to your
intended felling direction.
4. Drive a wedge or breaking bar into the cut as soon
as it is deep enough.

5. 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.
6. 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.
Note: 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 41 to find out which
lengths of bar are recommended for your
chainsaw.
