• 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 below).
• If cutting and felling is being carried
out by two or more persons simul-
taneously, the distance between the
felling and cutting persons must be
at least twice the height of the tree to
be fellled. 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 immedi-
ately.
• Dirt, stones, loose bark, nails, clips
and wires must be removed from the
tree.
Do not fell any trees when a
strong or changing wind is
blowing, if the danger of prop-
erty 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.
Removal of branches:
1.
Remove hanging branches by
positioning the cut from above
the branch. With removal of
branches, never work higher
than shoulder level.
Escape area:
2.
Remove the undergrowth around
the tree to ensure an easy
escape. The escape area (1)
should be around 45° either side
116
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 an upper sawing
cut.
Now make a sawcut below,
which runs horizontally and en-
counters the upper sawcut
exactly.
The depth of cut of the notch
should be approx. 1/3 of the
trunk diameter and the cutting
angle at least 45°.
Never step in front of a tree
which is notched.
Felling back cut (B):
4.
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 not less
than 5 cm above the horizontal
notched cut.
The back cut should be so deep
that the separation distance
between 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
designated as a break dimen-
sion
.
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.
If the trunk diameter is larger
5.
than the length of the chain bar,
make two cuts.
