that the tree is between you and the product.
2. Remove undergrowth from the work area around the
tree. Remove all cut off material from the work area.
3. Do a check of the area for obstacles such as stones,
branches and holes. You must have a clear path of

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 ¼ of the diameter of the
tree. Make a 45°-70° angle between the top
directional cut and bottom directional cut.
a) Make the top directional cut. Align the felling
direction mark (1) of the product with the felling
direction of the tree (2). Stay behind the product
and keep the tree on your left side. Cut with a
pull stroke.
b) Make the bottom directional cut. Make sure that
the end of the bottom directional cut is at the
same point as the end of the top directional cut.

2. Make sure that the bottom directional cut is
horizontal and at a 90° angle to the felling direction.
