UTILIZZO USE UTILISATION

FRENO CATENA

NORME DI SICUREZZA PER IL CONTRACCOLPO

Il contraccolpo si può verificare quando la punta della

barra tocca un oggetto o quando il legno blocca o

schiaccia la catena durante il taglio (Fig. 49-50-51). Per

prevenire e ridurre il contraccolpo, mantenere il

controllo della motosega impugnandola saldamente

con entrambe le mani.

FRENO CATENA INERZIALE

Il freno catena inerziale è un dispositivo di grande sicurezza

nell’uso della motosega. Protegge l’utilizzatore da eventuali

pericolosi contraccolpi che si potrebbero verificare durante

le varie fasi di lavoro. Viene attivato, con conseguente blocco

istantaneo della catena, quando la mano dell’operatore fa

pressione sulla leva (Fig. 52) (azionamento manuale), oppure

automaticamente per inerzia quando la protezione viene

spinta in avanti (Fig. 53) in caso di contraccolpo improvviso

(azionamento inerziale). Il freno catena si sblocca tirando la leva

verso l’operatore (Fig. 54).

CONTROLLO FUNZIONAMENTO FRENO

Quando si effettua un controllo della macchina, prima di

eseguire qualsiasi lavoro, verificare il funzionamento del freno

osservando i seguenti punti:

1. Avviare il motore ed afferrare le impugnature saldamente

con le due mani.

2. Tirare la leva acceleratore per mettere in movimento la

catena, spingere la leva del freno in avanti, utilizzando il

dorso della mano sinistra (Fig. 52).

3. Quando il freno funziona la catena si arresta

immediatamente; rilasciare la leva acceleratore.

4. Disattivare il freno (Fig. 54).

MANUTENZIONE FRENO: mantenere sempre pulito il

meccanismo del freno catena e lubrificare il leveraggio (Fig. 55).

Verificare l’usura del nastro freno. Lo spessore minimo deve

essere di 0.60 mm.

CHAIN BRAKE

KICKBACK SAFETY PRECAUTIONS

Kickback may occur when the tip of the guide bar

touches an object or when the wood closes in and

pinches the saw chain in the cut (Fig. 49-50-51). To

avoid and reduce kickback, keep the chainsaw under

control grasping it firmly with both hands.

INERTIAL CHAIN BRAKE

The inertial chain brake ensures maximum safety in using the

chainsaw. It protects the operator from dangerous kickback

which can occur during working phases. It is actuated, with

consequent instant locking of the chain, when the operator

presses the lever (Fig. 52) (manual operation) or automatically

by inertia when the protection is pushed forward (Fig. 53) in the

event of sudden kickback (inertial operation).

The chain brake is released by pulling the lever towards the

operator (Fig. 54).

CHECKING BRAKE OPERATION

At machine inspection prior to each job, check the operating

condition of the brake following the steps below:

1. Start the engine and grasp the handle securely with both

hands.

2. Pulling the throttle lever to maintain the chain operation,

push the brake lever down toward the front using the back of

your left hand (Fig. 52).

3. When the brake operates and the chain is stopped, release

the throttle lever.

4. Release the brake (Fig. 54).

BRAKE MAINTENANCE: always keep the chain brake

mechanism clean and lubricate the leverage (Fig. 55). Check

wear on the brake belt. Its minimum thickness must be

0.60 mm.

FREIN DE CHAINE

MESURES DE SECURITE POUR LE REBOND

Le rebond peut avoir lieu quand le nez du guide

touche un objet ou quand le bois bloque et écrase la

chaîne pendant la coupe (Fig.49-50-51). Pour prévenir

et réduire le rebond, maintenez le contrôle de la

tronçonneuse en la tenant fermement des deux mains.

FREIN DE CHAINE INERTIEL

Le frein de chaîne inertiel est un dispositif qui donne une

grande sécurité lors de l’utilisation de la tronçonneuse. Il

protège l’utilisateur des dangereux contrecoups éventuels qui

pourraient se produire durant les diverses phases de travail. Il se

met en marche, provoquant le blocage instantané de la chaîne,

lorsque la main de l’opérateur fait pression sur le levier (Fig.52)

(actionnement manuel), ou bien automatiquement par inertie

lorsque l’on pousse la protection vers l’avant (Fig.53) en cas de

brusque contrecoup (actionement inertiel). Le frein de chaîne

se débloque en tirant le levier vers l’opérateur (Fig.54).

CONTROLE DU FONCTIONNEMENT DU FREIN

Lors du contrôle de la machine avant de l’utiliser, vérifiez l’état

de fonctionnement du frein en effectuant le opérations ci

dessous:

1. Lancez le moteur et saisissez fermement la poignée des deux

mains.

2. Tout en tirant la manette de commande des gaz pour

maintenir la chaîne en opération, poussez le levier de frein

vers le bas et l’avant avec le dos de la main gauche (Fig. 52).

3. Lorsque le frein fonctionne et que la chaîne est arrêtée,

retirez la main de la manette des gaz.

4. Débloque le frein (Fig. 54).

ENTRETIEN DU FREIN: Veillez à ce que le mécanisme du frein

de chaîne soit toujours propre et lubrifiez l’ensemble des leviers

(Fig. 55). Vérifiez l’usure du ruban du frein. L’épaisseur minimum

doit être de 0.60 mm.
