To fell a tree
Husqvarna recommends you to make the directional
cuts and then use the safe corner method when you fell
a tree. The safe corner method helps you to make a
correct felling hinge and control the felling direction.
WARNING: Do not fell trees with a diameter
that is more than two times larger than the
guide bar length. For this, you must have
special training.
The felling hinge
The most important procedure during tree felling is to
make the correct felling hinge. With a correct felling
hinge, you control the felling direction and make sure
that the felling procedure is safe.
The thickness of the felling hinge must be equal and a
minimum of 10% of the tree diameter.
WARNING: If the felling hinge is incorrect or
too thin, you have no control of the felling
direction.
To make the directional cuts
1. Make the directional cuts. Run the directional cuts
1/4 of the diameter of the tree. Make a 45° angle
between the top cut and bottom cut.
a) Make the top cut first. Align the felling direction
mark (A) of the product with the felling direction
of the tree (B). Stay behind the product and keep
the tree on your right side. Cut with a pull stroke.

b) Make the bottom cut. Make sure that the end of
the bottom cut is at the same point as the end of
the top cut.

2. Make sure that the directional cut line is perfectly
horizontal and at right angles (90°) to the felling
direction. The directional cut line goes through the
point where the two directional cuts touch.
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).
