3. Limiting access to danger zones:
- Limit access to the area by marking it off with
warning signs.
4. Precautions to be taken according to
weather conditions for people in the area and
eventual local regulations:
- IMPORTANT! Do not use the chain saw in ad
-
verse weather conditions: rain, snow, low visibility,
near cables or electrical networks, or where there
may be a risk of explosions.
- Never cut in the presence of people or animals
and keep at a distance twice the height of the tree.
5. Preparing and using escape routes (see also
point 6):
-IMPORTANT! Before you begin felling a tree, you
must decide the fall direction, identify the escape
route and then eliminate all obstacles along it.
N.B.: The direction of the fall is determined by
the cut.
-The escape routes for the operator are outlined in
figure below.

b) Danger area
c) Escape route
6. Felling trees on slopes:
- IMPORTANT! When felling a tree on a slope,
the operator must position themselves on the
upper side because, once the tree is cut, it will roll
downhill.
7. Felling trees in relation to the saw’s cutting
capacity:
- Do not make cuts on diameters greater than the
maximum cutting length (see technical specifica
-
tions) It is always better not to exaggerate the
diameter of the cut
8. How to control the fall direction of the tree
being cut:
- Usually, felling a tree consists of two main cuts,
the face cut and the undercut which is needed to
fell the tree.
- Begin with the face cut on the side of the tree fac-
ing the direction of the fall.
- The cut must be as deep as about 1/3 of the
trunk diameter.
- After this operation, make the cut on the other
side of the tree at about 5 cm above the height of
the face cut (Fig. 1).
- Do not walk in front of the tree on the fall side
after you have made the cut.
- IMPORTANT! Before proceeding with the final
cut, check that there are no persons, animals, or
objects in the fall area.
- IMPORTANT! When the tree begins to fall,
extract the chain saw from the cut, lay it on the
ground, and leave the area quickly along the
escape route
9. Using wedges for felling trees:
- Use wooden or plastic wedges (G Fig.2) to
prevent the bar or the chain from getting lodged in
the trunk.
- IMPORTANT! When the tree begins to fall,
extract the chain saw from the cut, lay it on the
ground, and leave the area quickly along the
escape route.
10. Cutting branches (debranching):
- This operation consists of cutting the branches
of felled trees. Note: Do not cut the branches that
support the felled tree before cutting it in pieces.
(Fig.3)
- IMPORTANT! Do not climb onto the trunk to cut
it.
