5-3. BUCKING

 

Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the log

 

when cutting on sloping ground. If possible, the log should be supported so that the end to be cut off is not

 

resting on the ground. If the log is supported at both ends and you must cut in the middle, make a down-

E

ward cut halfway through the log and then make the undercut. This will prevent the log from pinching the

 

bar and chain. Be careful that the chain does not cut into the ground when bucking as this causes rapid

N dulling of the chain.

G When bucking on a slope, always stand on the uphill side.

L

1. Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting into the

Iground (Figure 5-3A).

S2. Log supported on 1 end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid splintering.

H Second, cut from above (overbuck) to meet first cut and avoid pinching (Figure 5-3B).

3.Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering. Second, under- buck to meet first cut and avoid pinching (Figure 5-3C).

NOTE: The best way to hold a log while bucking is to use a sawhorse. When this is not possible, the log should be raised and supported by the limb stumps or by using supporting logs. Be sure the log being cut is securely supported.

5-3. TRONCONNAGE

Nous entendons par tronçonnage la découpe d’un tronc abattu. S’assurer d’avoir une bonne assise et de se trouver derrière le tronc quand le terrain est incliné. L’extrémité à scier devrait, si possible, ne pas repos- er sur le sol, mais être supportée. Si le tronc est supporté aux deux extrémités et que la coupe doit se faire

F au milieu, faire une coupe vers le bas et jusqu’au milieu, puis faire la coupe par en-dessous. ceci empêche le bois de coincer la chaîne ou guide-chaîne. Faire attention à ne pas scier jusque dans le sol car la chaîne

R s’émoussera rapidement.

APour le tronçonnage sur pente, se placer toujours vers le haut.

N1. Si le tronc est supporté sur toute sa longueur: Il peut être tronçonné à partir du dessus. Eviter de

Cplonger le guide-chaîne dans la terre (Figure 5-3A).

A2. Tronçonnage d’un tronc supporté à une extrémité: Effectuer d’abord une coupe par le dessous (sous-

I coupe) sur 1/3 du diamètre, de manière à éviter l’éclatement du bois. Ensuite, effectuer une coupe par

S dessus (sur-coupe) pour joindre la première coupe et éviter tout coinçage (Figure 5-3B).

3.Tronçonnage d’un tronc supporté aux deux extrémités: Effectuer d’abord une coupe par dessus sur 1/3

du diamètre de façon à éviter l’éclatement du bois. Ensuite, effectuer une coupe par dessous (sous- coupe) pour joindre la première coupe et éviter tout coinçage (Figure 6-3C).

REMARQUE: Un chevalet est le meilleur support pour tronçonnage. Si cela n’est pas possible, soutenir le tronc par des bûches ou par les chicots des branches. S’assurer que le tronc à couper est bien supporté.

 

5-3. LEÑADO

 

Leñado es cortar un tronco caído en pedazos. Asegúrese de tener una buena base para los pies y pararse

 

hacia arriba del tronco cuando corte en un terreno con pendiente. Si es posible, el tronco deberá ser apoy-

 

ado de manera que el extremo que será cortado no repose en el suelo. Si el tronco esta apoyado en los

 

dos extremos y usted tiene que cortar en la mitad, realice un corte inclinado hasta la mitad dentro del tron-

E

co y luego realice el corte por abajo. Esto evitará que el tronco pellizque la barra y cadena. Tenga cuidado

S

de que la cadena no corte dentro del suelo cuando leñe, esto causa un rápido desafilado de la cadena.

Cuando leñe en una pendiente, siempre parese en la parte de arriba.

P

1. Tronco apoyado a lo largo de toda la longitud: Corte desde arriba (leñar por arriba), siendo cuidadoso

A

para evitar cortar dentro del suelo (Figura 5-3A).

Ñ2. Tronco apoyado en 1 extremo: Primero, corte desde abajo (leñar por abajo) 1/3 del diámetro del tron-

Oco para evitar astillamiento. Segundo, corte desde arriba (leñar por arriba) para encontrar el primer

L corte y evitar el pellizcado (Figura 5-3B).

3.Tronco apoyado en ambos extremos: Primero, Leñe por arriba 1/3 del diámetro del tronco para evitar astillamiento. Segundo, leñe por abajo para encontrar el primer corte y evitar el pellizcado (Figura 5-

3C).

NOTA: La mejor manera de sostener un tronco mientras es leñado es usar un caballete de leñado. Cuando esto no es posible, el tronco deberá ser levantado y soportado por las ramas soporte o usando troncos de soporte. Asegúrese de que el tronco que esta siendo cortado este seguramente apoyado.
