a) Make a bore cut straight into the trunk to
complete the felling hinge width.
b) Cut on the pull stroke until ⅓ of the trunk is left.
c) Pull the guide bar 5-10 cm/2-4 in rearward.
d) Cut through the remaining of the trunk to
complete a safe corner that is 5-10 cm/2-4 in
wide.
2. If the usable cutting length is shorter than the tree
diameter, do these steps (a-d).
a) Make a bore cut straight into the trunk. The
bore cut must extend 3/5 of the tree diameter.
b) Cut on the pull stroke through the remaining
trunk.
c) Cut straight into the trunk from the other side of
the tree to complete the felling hinge.
d) Cut on the push stroke, until ⅓ of the trunk is
left, to complete the safe corner.
3. Put a wedge in the kerf straight from behind.
4. Cut off the corner to make the tree fall.
Note:
If the tree does not fall, hit the wedge until
it does.
5. When the tree starts to fall, use the path of retreat
to move away from the tree. Move a minimum of 5
m/15 ft away from the tree.
To free a trapped tree
WARNING:
It is very dangerous to
remove a trapped tree and there is a high
accident risk. Keep out of the risk zone and
do not try to fell a trapped tree.
The safest procedure is to use one of the following
winches:
• Tractor-mounted
• Portable
To cut trees and branches that are in tension
1. Figure out which side of the tree or branch that is in
tension.
