8.1 FELLING
The operation of TREE FELLING
requires professionally trained and
qualified personnel.
Reading of these instructions is always neces-
sary, but is not a substitute for adequate expe-
rience in performing this delicate operation.
- Before felling. Ensure that:
1) There are no other people or animals within the
range of the fallen tree.
2) Select the direction in which the tree is to fall
in such a way that you can move away in the op-
posite direction (fig 17).
3) Check that the escape rout is free of obstacles.
4) Select the direction of fall taking account of the
following variables.
a) –Branches weighted towards one side.
b) – Slant of the tree.
c) – Direction of the wind (do not fell when the
wind is strong)
d) – Damaged wood
5) Carefully observe the environmental conditions
described in "GENERAL SAFETY REGULA-
TIONS point A6".
6) Free the base of the trunk, cutting branches
and big roots.
7) To decide the direction of fall:
a) Cut a notch (fig.12) on the side of the trunk
towards which you want it to fall. Penetrate to
about 1/3 of the trunk diameter.
CHAIN SAW OPERATING MANUAL
b) Make the felling cut from the opposite side from
the notch (fig.13) about 5 cm higher up.
c) ATTENTION !! Do not complete the cut but
leave enough wood to act as a hinge when the
tree falls, controlling the direction of fall (fig.13
part.1).
d) Use a wedge to start the fall (fig.14).
e) As soon as the tree starts to fall, move away in
the direction decided on previously.
8.2 CUTTING OF BRANCHES AND THE TRUNK
ON THE GROUND
Trunk resting on its ends:
1) Make a cut from above to 1/3 of the diameter
(fig.15).
2) Complete the cut from below with the top part
of the bar.
Branch/Trunk projecting freely:
1) Start with a cut from below to 1/3 of the diameter
(fig.16) with the top part of the bar.
2) Complete the cut from the top.
8.3 CHAIN BRAKE
Your chainsaw is provided with a safety brake
to lock the chain in a fraction of a second in the
event of a kickback.
a) The brake engages automatically in case of a
strong kickback produced by brake lever inertia
(fig.30).
