NORME DI LAVORO
ATTENZIONE – Abbattere un albero è un’operazione che
richiede esperienza. Non tentare di abbattere alberi se
siete inesperti. EVITATE TUTTE LE OPERAZIONI PER LE
QUALI NON VI SENTITE QUALIFICATI! Si raccomanda agli
operatori inesperti di astenersi dall’abbattere alberi il cui
tronco abbia un diametro superiore alla lunghezza della
barra.
Se si usa la motosega per la prima volta, eseguire alcuni
tagli su di un tronco stabile per acquisire sicurezza
nell’uso. Durante il taglio accelerare al massimo. Non
spingere eccessivamente sulla motosega; il solo peso
della stessa permetterà di tagliare con il minimo sforzo.
ATTENZIONE - Non tagliare quando c’é cattivo tempo,
scarsa visibilità, temperature troppo rigide o elevate.
Assicurarsi che non ci siano rami secchi che possono
cadere.
ABBATTIMENTO
Nelle operazioni di abbattimento e sezionatura sfruttare la
presenza dell’arpione, facendo perno su di esso. Studiare bene
l’albero e il terreno circostante prima di cominciare a tagliare.
Liberare la zona di lavoro. Prepararsi un’ampia possibilità di
arretramento per quando l’albero inizierà la caduta (Fig. 57).
Togliere gli eventuali rami presenti nella parte inferiore del tronco
per circa 2 metri. Praticare un taglio perpendicolare alla pianta
corrispondente a 1/4 del diametro del tronco, iniziandolo dalla
parte dove si prevede la caduta (1 - Fig. 58).
Circa 10 cm più in alto iniziare un secondo taglio che vada a
congiungersi alla fine del primo taglio. Si asporterà così un cuneo
che darà la direzione dove cadrà la pianta (2 - Fig. 58).
Praticare ora dalla parte opposta al primo taglio il vero taglio di
abbattimento che dovrà essere posizionato 4-5 cm più in alto del
primo (3 - Fig. 58).
Lasciare sempre una cerniera (A, Fig. 59-60) che consenta il
controllo della direzione di caduta. Mettere un cuneo nel taglio di
abbattimento, prima che l’albero cominci a muoversi, per evitare
che la barra della motosega venga bloccata.
Se il diametro del tronco è superiore alla lunghezza della barra
eseguire il taglio di abbattimento come la sequenza indicata in
Fig. 60.
OPERATING INSTRUCTIONS
WARNING - Tree filling is a task that requires experience.
Not groped tree filling if you are inexperienced. AVOID
ALL TRANSACTIONS FOR WHICH YOU ARE NOT QUALIFIED!
It is recommended that inexperienced operators to refrain
tree filling if the trunk has a diameter greater than the
length of the bar.
When using the chainsaw for the first time, make several
cuts in a small trunk in order to become familiar with the
saw in action. Always use full throttle when cutting with
the saw, regardless of the size of the timber. Never push
down on the saw when cutting. The weight of the saw
alone enables it to cut properly with minimum effort.
WARNING - Never cut in high wind, bad weather, when
visibility is poor or in very high or low temperatures.
Always check the tree for dead branches which could fall
during the felling operation.
TREE FELLING
In tree filling and bucking operations exploit the presence of spike
bumpers, pivoting on it. Study the tree and surrounding area
before starting to cut. Clear the work area before beginning to cut.
Prepare the widest possible path of retreat for when the tree falls
(Fig. 57). Cut off any branches at the bottom of the trunk up to a
height of about 2 metres. Make a 90 degree notch on the face of
the tree, in the direction it will fall. The depth of the notch should
never exceed 1/4 of the diameter of the trunk (1 - Fig. 58). About 10
cm (4”) higher up the trunk make a cut down towards the first cut,
in order to extract a wedge. This is the mouth of the hinge, and is
the direction in which the tree falls (2 - Fig. 58).
Now, make your felling cut on the opposite side of the trunk. Start
the cut about 4-5 cm (2”) higher than the center of the notch (3 -
Fig. 58).
Always leave a hinge (A, Fig. 59-60) which allows you to control the
direction the tree falls in. Put a wedge into the felling cut, before
the tree starts to move, to prevent the chainsaw guide bar from
getting stuck.
If the diameter of the trunk is greater than the length of the guide
bar, make the felling cut as shown in the sequence of Fig. 60.
UTILISATION
ATTENTION – Abattre un arbre est une opération
qui nécessite une certaine expérience. N'essayez pas
d'abattre des arbres si vous n'en avez pas encore
l'expérience. ÉVITEZ TOUTES LES OPÉRATIONS POUR
LESQUELLES VOUS NE VOUS SENTEZ PAS QUALIFIÉS ! Il est
recommandé aux opérateurs inexperts de ne pas abattre
d'arbres dont le tronc présente un diamètre supérieur à la
longueur de la barre.
Si l’on utilise la tronçonneuse pour la première fois, il
faut d’abord s’exercer sur des petites bûches pour se
familiariser avec le fonctionnement. En coupe, utilisez la
machine au maximum de sa puissance. Ne forcez pas sur
les poignées ; la machine doit descendre en coupe de son
propre poids et vous permettre de couper sans le moindre
effort.
ATTENTION - Ne coupez jamais si le temps est mauvais,
si la visibilité est insuffisante ou si la température est
trop basse ou trop élevée. Assurez vous qu’il n’y a pas de
branches sèches qui puissent tomber.
ABATTAGE
Lors des opérations d'abattage et de découpe, utilisez le harpion
comme point d'appui. Avant de commencer à couper, étudiez
bien l’arbre, le terrain et ses environs. Dégagez la zone de travail.
Préparez un vaste espace pour pouvoir reculer lorsque l’arbre
commencera à tomber (Fig.57). Otez les branches qui seraient
éventuellement sur environ deux mètres de la partie basse du
tronc. Effectuez en sens perpendiculaire par rapport à la plante,
une entaille correspondant à environ 1/4 du diamètre du tronc,
en commençant du côté où vous prévoyez la chute de l’arbre
(1- Fig.58). A environ 10 cm un peu plus haut, commencez une
seconde entaille qui rejoigne la première. Otez ainsi un coin qui
donnera la direction vers laquelle l’arbre tombera (2-Fig.58).
Pratiquez maintenant, du côté opposé à la première coupe, la
véritable entaille d’abattage qui devra être positionnée 4-5 cm plus
haut par rapport à la première entaille (3-Fig.58).
Laissez toujours une charnière (A-Fig.59-60) qui permette le
contrôle de la direction de chute. Mettez un coin dans l’entaille
d’abattage, avant que l’arbre ne commence à bouger, de façon à
éviter que le guide de la tronçonneuse ne reste bloqué.
Si le diamètre du tronc est supérieur à la longueur du guide,
effectuez l’entaille d’abattage suivant la séquence indiquée sur la
Fig.60.
