To clear the trunk and prepare your path of
retreat
Cut off all branches from your shoulder height and
down.
1. Cut on the pull stroke from the top down. Make sure
that the tree is between you and the product. (Fig.
85)
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 retreat when the tree starts to fall. Your path of
retreat must be approximately 135 degrees away
from the felling direction.

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:
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:
incorrect or too thin, you have no control of
the felling direction.
(Fig. 87)
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. (Fig. 88)
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. (Fig. 89)
To use the safe corner method
The felling cut must be made slightly above the
directional cut.
(Fig. 90)
WARNING:
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.
(Fig. 91)
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. (Fig. 92)
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. (Fig. 93)
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. (Fig. 94)
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. (Fig. 95)
3. Put a wedge in the kerf straight from behind. (Fig.
96)
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:
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.
Be careful when you cut
