is a risk of damage to property or if the tree
could hit power lines. When felling trees,
ensure that no other persons are subject
to hazards and that no material damage is
caused. If a tree should come into contact
with a power line, the supply company must
be informed immediately.
CAUTION! For safety reasons, we advise
inexperienced users against felling a tree
trunk with a blade bar length that is smaller
than the trunk diameter.
• Please make sure that no other persons
or animals are present in your work area.
The safety distance between the tree to
be felled and the nearest workplace must
be 2 ½ tree lengths.
• Pay attention to the felling direction. The
user must be able to move around safely
near the felled tree so that he can cut the
tree to size and cut off all branches easily.
The falling tree must be prevented from
becoming entangled in another tree.
• Please note that the natural falling direc-
tion depends on the pitch and crooked-
ness of the tree trunk, the wind direction,
position of larger branches and the num-
ber of branches.
• Stay above the tree to be felled when
sawing on a slope. The tree will probably
roll or slide downhill after felling.
• Small trees with a diameter of 15-18 cm
can usually be sawn off with one cut.
• For trees with a larger diameter, notch
cuts and a felling cut must be applied
(Fig. O).
• If cutting and felling is being carried out
by two or more persons simultaneously,
the distance between the felling and cut-
ting persons must be at least twice the
height of the tree to be felled.
Fold up the hearing protection immediately
after finishing the sawing process so that you
can hear sounds and warning signals.
Procedure
1. Limbing (Fig. T)
Remove branches hanging downwards
by sawing from the top of the branch.
Never saw off branches higher than
shoulder height.
2. Escape area (Fig. N)
Remove the undergrowth around the tree
to ensure an easy retreat. The escape
area (1) should be offset by about 45° be-
hind the planned felling direction (2).

3. Cut drop notch (A) (Fig. O)
Place a drop notch in the direction in
which you want the tree to fall. Start with
the lower, horizontal cut. The cutting
depth should be about 1/3 of the trunk
diameter. Now make an oblique saw cut
with a cutting angle of approximately
45° from above, which meets the lower
saw cut exactly. This prevents the saw
chain or guide rail from jamming when
the second notch cut is made.
WARNING! Never step in front of a
tree that is notched.
4. Felling cut (B) (Fig. O)
Make the felling cut from the other side
of the trunk. Stand to the left of the tree
trunk and saw with the saw chain pulling
(with the underside of the blade bar). The
felling cut must be at least 5 cm above
the horizontal notch section. It should be
deep enough so that the distance to the
notch cutting line is at least 1/10 of the
trunk diameter. The part of the log that
has not been sawn through is called the
hinge (felling bar). The hinge prevents the
tree from turning and falling in the wrong
direction. Do not cut through this hinge.
When the felling cut nears the hinge, the
tree should begin to fall. If it becomes ap-
parent that the tree will not fall in the de-
sired direction or if it bends back, and if
the saw chain is stuck, discontinue the
felling cut. Use wooden, plastic or alu-
minium wedges to open the cut and fell
the tree to fall into the desired fall line.
5. Slide a cutting wedge into the felling cut
as soon as the cutting depth so permits,
in order to prevent the blade bar from
getting jammed (Fig. P).
6. If the trunk diameter is greater than the
length of the blade bar, make two cuts
(Fig. R).
7. Once the felling cut has been made, the
tree falls by itself or with the help of the
felling wedge.
WARNING! As soon as the tree starts to
fall, pull the chainsaw out of the cut, stop the
engine, put the chainsaw down and leave the
workplace via the retreat path. Pay attention
to falling branches and do not stumble.
Limbing
Limbing is the term for removing branches
and twigs from a felled tree.
