WARNING:
mean a risk that the tree falls before you
complete the cutting.
5. Make sure the tree has no damaged or dead
branches that can break off and hit you during
felling.
6. Do not let the tree fall onto a different standing tree.
It is dangerous to remove a caught tree and there is
a high accident risk. Refer to
on page 29 . (Fig. 75)
WARNING:
operations, lift your hearing protection
immediately when the sawing is
complete. It is important that you hear
sounds and warning signals.
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.
76)
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.
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.

During critical felling
Do not fell trees with a
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. 78)
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. 79)
To make the felling cut
Note:
The felling cut is made on the opposite side of
the tree from the directional cuts.
1. Make the felling cut approximately 3-5 cm/1.5-2 in
above the bottom directional cuts. The cut must be
perfectly horizontal. (Fig. 80)
2. If you have a spiked bumper, put it behind the felling
hinge.
3. Cut on the pull stroke, use full power and forward the
saw chain/guide bar slowly into the tree. Make sure
that the tree does not fall in an unwanted direction.
4. Operate a wedge or breaking bar into the cut when
the cut has accurate depth. (Fig. 81)
5. Complete the felling cut parallel with the directional
cut line. Make sure that the distance between them
is at a minimum of 1/10 of the trunk diameter. The
section of the trunk that is not cut is the felling hinge.
The felling hinge controls the felling direction. (Fig.
82)
WARNING:
the felling direction if the felling hinge is
gone or if it is too thin. This also applies
to if you have not made the directional
cuts and felling cut correctly.
(Fig. 83)
6. At this time, the tree will fall by its own force or with
the aid of a wedge or breaking bar. (Fig. 84)
Note:
Use a guide bar that is longer than the diameter
of the tree. This helps you to make the felling cut and
directional cuts with one cutting stroke each. See
Accessories on page 37 to find out which bar lengths
we recommended for your product.

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.
