8. USE
a) Cut a notch (Fig. 12) on the side of the trunk to-
wards 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).
• Always hold the equipment firmly with both hands
(Fig. 11).
• Comply with all the rules described in the previ-
ous section “SAFETY”.
Cut with the throttle trigger pressed to the maximum
and make contact with the wood when the engine
has reached full speed.
8.1 FELLING
The operation of TREE FELLING requires pro-
fessionally trained and qualified personnel.
Reading of these instructions is always necessary,
but is not a substitute for adequate experience 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 opposite direction.
3) Check that the escape rout is free of obstacles.
4) Select the direction of fall taking account of the fol-
lowing 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 de-
scribed in “ GENERAL SAFETY REGULATIONS point
A6”.
6) Free the base of the trunk, cutting branches and big
roots.
7) To decide the direction of fall:
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
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
Your chainsaw is provided with a safety brake to lock the
chain in a fraction of a second in the event of a kick-
back.
a) The brake engages automatically in case of a strong
kickback produced by brake lever inertia (fig. 30).
