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 sig-
nals.
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.
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
direction (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 saw-
ing 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 horizon-
tally 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 .
Slide a cutting wedge or crow-
bar into the felling cut as soon
as the cutting depth so permits,
in order to prevent the blade
from getting jammed. When
the felling cut nears the hinge,
the tree should begin to fall. If it
becomes apparent that the tree
might not fall into the desired
