CHAIN SAW OPERATING MANUAL
GB
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.
ENGLISH
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.
a)
The brake engages automatically in case of
a strong kickback produced by brake lever
inertia (fig. 31).
Fig. 31
STOP
b)
In case of a less strong kickback, the chain
brake can be automatically engaged by
consequent contact of the lever with the left hand.
Consequently: always grip the chainsaw
with both hands.
Always remember that the chain brake
d o e s n o t r e p r e s e n t a t o t a l
protection. It is therefore crucial
to avoid all the hazard situations explained
in the previous SAFETY DEVICE CHAPTER
(points of paragraphs A17-A18)
c)
The chain brake can be applied manually by
pushing it forward.
- The brake is released by pulling the lever to-
wards the front handle (Fig. 32).
