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

. 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

, make the

ellin

cut as shown in the sequence o

. 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

amais 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 re

oigne 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 tou

ours 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

.60.
