easily and remove branches.It is to be
avoided that the felled tree snags itself
on another tree. Note the natural fell-
ing direction, which is dependent on
the slope and curvature characteristic
of the tree, wind direction and the
number of branches.
• In the case of sloping ground, stand
above the tree to be felled.
• Small trees, with a diameter of 15-18
cm, can usually be sawn off with one
cut.
• In case of trees with a larger diameter,
a notched cut and a back cut must be
implemented (see diagram Q ).
Do not fell any trees when
a strong or changing wind
is blowing, if the danger of
property damage exists or if
the tree could fall on electric
wires.
Immediately after termination of
the sawing procedure, remove the
ear protection so that you can hear
hooter and alarm signals.
1. Removal of branches:
Remove hanging branches by
positioning the cut from above the
branch. With removal of branches,
never work higher than shoulder
level.
P
2. Escape area:
Remove the undergrowth around
the tree to ensure an easy es-
cape. The escape area (1) should
be around 45° either side behind
the planned felling direction (2).
Q
3. Cutting notch (A):
Make a felling notch in the direc-
tion in which you wish the tree to
fall. Start with the bottom, hori-
zontal cut. The cut depth should
be around 1/3 of the trunk diam-
eter. 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.
Q
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
log not sawed through is desig-
nated as a break dimension.
R
Insert a felling wedge or a crow-
bar into the back cut, as soon as
the depth of cut permits this, in
order to prevent a jamming of the
chain bar.
S
5. 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.
