To use the safe corner method
The felling cut must be made slightly above the
directional cut.
WARNING: Be careful when you cut with the
guide bar tip. Start to cut with the lower
section of the guide bar tip as you make a
bore cut into the trunk.
1. If the usable cutting length is longer than the tree
diameter, do these steps (a-d).
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.
