8.1 FELLING
The operation of TREE FELLING requires
professionally trained and qualified per-
sonnel.
If the power saw is to be used near electri-
cal lines, roads or railway lines with poten-
tial dangers, inform the relevant authorities
and their agencies.
Reading of these instructions is always
necessary, but is not a substitute for ad-
equate experience in performing this deli-
cate 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
opposite direction.
3) Check that the escape rout is free of obsta-
cles.
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 condi-
tions described in "GENERAL SAFETY REGU-
LATIONS 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.
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 diam-
eter (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.
- The brake is applied automatically in the event
of a kickback actuated by the inertia of the brake
lever (Fig. 31).
Always grip the chainsaw firmly with both
hands.
