Remplacement de la courroie de transmission au sol

a.Enlevez la pince en épingle à cheveux et la pince de retenue (fig. 18) du moyeu de la roue gauche. Tirez la roue à environ 3 ou 4 cm de la fraiseuse.

b.Enlevez le protège-courroie en enlevant deux vis, un écrou hexagonal et trois rondelles de façon à pouvoir dégager le protège-courroie du moteur (fig. 18).

c.Dégagez les guide-courroie (fig. 17, encart)

d.Enlevez la courroie ussagée en la dégageant d'avord de la poulie du galet-tendeur (fig. 17).

e.Placez la courroie neuve dans la rainure de la poulie de transmission (grande poulie) et dans la rainure de la courroie du moteur (fig. 17). La courroie doit être dans la rainure en haut de la poulie du galet-tendeur (fig. 17). Notez la position de la courroie par rapport aux guides- courroie.

f.Serrez les guides-courroie par rapport aux guides- courroie (fig. 17, encart)

Changement des dents

Une dent très usagée fait travailler votre fraizeuse plus péniblement et labourer moins profondément. Plus encore, des dents usées ne peuvent couper ni déchirer les matieres organiques, ni les enterrer aussi profondément que de bonnes dents. A ce point d'usure (fig. 19), la dent doit être changée.

Pour maintenir l'exvellente capacité de fraisage de cette machine il faut contrôler le coupant, l'usure et la courbure des dents, et en particulier des dents les plus proches de la transmission (fig. 20). Si l'écart entre les dents dépasse 9 cm, il faut les changer et les redresser si nécessaire.

Les dents neuves sont mises en place comme indiqué à la figure 21. Le tranchant des dents affIutées doit tourner vers l'arrière, vu du dessus (fig. 21).

IMPORTANT!

Ne touchez pas au régulateur du moteur qui est préréglé en usine à la vitesse convenable.
