information
The directional cut should run 1/4 of the diameter (A)
through the trunk and the angle between the TOP CUT
and BOTTOM CUT should be 45°.
information
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.
information
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 with the bottom edge of the bar.
3. After removing the wood from the notch, make the
felling cut on the opposite side of the notch. Make
the FELLING CUT about 5 cm (A=2 inches) above
the flat section of the DIRECTIONAL CUT. This will
leave enough uncut wood between the felling cut
and the notch to form a hinge. This hinge will hold
tree on stump and control the tree falling in the
correct direction.
4. Set the spike bumper (if one is fitted) in behind the
breaking strip. Use full throttle and bring the bar
and chain slowly into the tree. Make sure the tree
does not start to move in the opposite direction to
your intended felling direction.
5. Drive a WEDGE or BREAKING BAR into the cut as
soon as it is deep enough.
6. Finish the FELLING CUT parallel with the
DIRECTIONAL CUT LINE so that the distance
between them is at least at least 1/10 (C) of the
trunk diameter. The uncut section of the trunk is
called the BREAKING STRIP.
c
information
The BREAKING STRIP act as hinges that control the
felling direction of the falling tree.
7. When the felling cut and directional cut are
complete the tree should start to fall under its own
