2. Escape area:
Remove the undergrowth around
the tree to ensure an easy
escape. The escape area (1)
should be around 45° either side
behind the planned felling direc-
tion (2).
3. Cutting notch (A):
Make a felling notch in the direc-
tion in which you wish the tree
to fall. Start with the bottom,
horizontal cut. The cut depth
should be around 1/3 of the
trunk diameter. This will prevent
the saw chain or the guard rails
from jamming when placing the
second chamfer. Now make a
slanted saw cut from above at
an angle of roughly 45° to meet
exactly with the bottom saw cut.
Never step in front of a tree
which is notched.
4. Felling back cut (B):
Make the back cut from the other
side of the log, where you stand
to the left of the log and saw with
the chainsaw pulling. The back
cut must run horizontally 5 cm
above the horizontal notched cut.
The back cut should be so deep
that the separation distance be-
tween the back cut and the notch
cutting line is at least 1/10 of
the trunk diameter. The part of
the stem not sawn through is
called a stay (felling gib). The
stay prevents the tree from turn-
ing and falling in the wrong di-
rection. Do not saw through the
stay.
5. As you approach the felling cut
on the stay the tree should start
falling. If it becomes apparent
that the tree may not fall in the
required direction or is lean-
ing back, and the saw chain is
jamming, stop felling and use
wedges made of wood, plastic
or aluminium to open the cut
and to tilt the tree in the required
felling line.
6. If the trunk diameter is larger
than the length of the chain bar,
make two cuts.
For safety reasons, we ad-
vise inexperienced users not
to fell any logs with a rail
length which is smaller than
the trunk diameter.
7. After carrying out of the back
cut, the tree falls by itself or with
the aid of the felling wedge or
crowbar.
As soon as the tree begins
to fall, pull out the saw from
the section, stop the motor,
place the chainsaw down
and leave the workplace us-
ing the withdrawal path.
Pay attention to falling
branches and do not stumble.
