ANGLE D’AFFÛTAGE DE LA PLAQUE SUPÉRIEURE

Voir la figure 53.

n CORRECT 30° − Les porte-limes sont dotés de repères permettant d’aligner la lime correctement, de façon à obtenir un angle de plaque supérieure satisfaisant.

n MOINS DE 30° − Pour le tronçonnage

n PLUS DE 30° − Tranchant aminci, s’émousse rapidement.

ANGLE DE PLAQUE LATÉRALE

Voir la figure 54.

n CORRECT 80° – Obtenu automatiquement si une lime de diamètre approprié est placée dans le porte-limes.

nCROCHET – « Accroche » le bois et s’émousse rapidement, ce qui accroît le risque de REBOND.

Voir les figures 55 à 57.

nLe jeu du limiteur de profondeur doit être maintenu à 0,6 mm (0,025 po). Utiliser une jauge de profondeur pour vérifier le jeu du limiteur.

nVérifier le jeu du limiteur de profondeur lors de chaque affûtage de la chaîne.

n Utiliser une lime plate et un coupleur pour limer tous les limiteurs de profondeur uniformément. Utiliser un coupleur de limiteur de 0,6 mm (0,025 po). Après avoir abaissé chaque limiteur de profondeur, lui rendre sa forme d’origine
