electric chainsaw if you feel
unsure about anything.
For safety reasons, we advise inex-
perienced users not to fell any logs
with a rail length which is smaller
than the trunk diameter.
•
Ensure that no people or animals are
tance between the tree to be felled and
the nearest-located workplace must be
2 ½ tree lengths.
•
Note the felling direction:
The user must be able to move safely
near the felled tree, to saw off the tree
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.
•
For sowing work on hillsides, the user
of the chainsaw should stay in the
area above the tree that is to be felled,
as the tree will probably roll down or
slide off downhill after being 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
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.
When felling trees, ensure
that no other persons are
exposed to hazards, that
no supply lines are hit, and
that no property damage is

caused. If a tree should come
into contact with a supply
line, the utility company must
be informed immediately.
Immediately after termination of
the sawing procedure, remove the
ear protection so that you can hear
hooter and alarm signals.
Remove hanging branches by
positioning the cut from above
the branch. With removal of
branches, never work higher than
shoulder level.
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).
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.
This helps avoiding that the
chainsaw or the guide rail jams
when making the second chip
carving.
Never step in front of a tree
which is notched.
