Disengage the CHAIN BRAKE® (D) by pulling it backward (Figure 3-5B).
1. Loosen the bar retaining nuts (E) so they are hand tight (Figure 3-5B).
REMARQUE : La tension d’une chaîne neuve doit être contrôlée fréquemment pendant son rodage, après aussi peu que cinq coupes. Les intervalles entre réglages s’espaceront rapidement (Figure 3-5A).
ATTENTION
Si un chaîne est TROP TENDUE ou TROP LACHE, le guide-chaîne et les roulements de vilebrequin s’useront plus rapidement. Etudier la Figure 3-5A pour tout renseignement concernant la tension appropriée pour moteur chaud (A) ou froid (B), et comme guide indiquant quand la chaîne a besoin d’être ajustée (C).
REGLAGE DE LA TENSION DE LA CHAINE :
REMARQUE : S’assurer que le frein de chaîne CHAIN BRAKE® est débloqué. Débloquer CHAIN BRAKE® (D) en le poussant vers l’arrière (Figure 3-5B).
1. Desserrer les écrous (E) du guide-chaîne jusqu’à ce qu’ils puissent être serrés à la main (Figure 3-5B).
NOTA: Una cadena y barra nueva requerirán un reajuste después de por lo menos 5 cortes. Esto es nor- mal dentro del periodo de acondicionamiento, y el intervalo dentro de los proximós ajustes se alagará pronto (Figura 3-5A).
PRECAUCION
TO ADJUST SAW CHAIN TENSION:
If a chain is TOO LOOSE or TOO TIGHT, the bar chain and saw bearings will wear more rapidly. Study Figure 3-5A for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C).

PSi la cadena se encuentra muy SUELTA o muy APRETADA, la barra, cadena y los rodamientos del cigueñal

Ase desgastaran más rápidamente. Estudie la Figura 3-5A para información respecto a la tensión fría cor-

Ñrecta (A), tensión caliente correcta (B), y como una guía para cuando la cadena de la sierra requiera algún

Oajúste (C).

LPARA AJUSTAR LA TENSION DE LA SIERRA:

NOTA: Asegúrese de que el CHAIN BRAKE® (D) se encuentre desactivado. Desactive el CHAIN BRAKE® jalándolo hacia atrás (Figura 3-5B).

1. Afloje las tuercas retendoras (E) de manera de que queden con tensión de la mano (Figura 3-5B).
