(4)Engager la plaque de guidage dans la couronne et tourner la plaque de guidage à gauche ou à droite de manière à ce qu’elle à ce qu’elle ne puisse pas tomber, même si elle orientée vers le bas. (Fig. 19)

2.Perçage (Fig. 20)

(1) Brancher la perceuse.

(2) Un ressort est placé dans le goujon central. Appuyer légèrement l’outil perpendiculairement contre le mur ou le plancher. Toute la surface de la couronne doit être en contact avec le mur ou le plancher. Mettre en marche.

(3) Quand on a percé sur une profondeur d’environ 3/16" (5 mm), la position du trou est déterminée. Continuer à percer après avoir retiré le goujon central et la plaque de guidage de la couronne.

(4) Si l’on applique une force excessive, cela donnera un travail bâclé et abîmera la pointe du foret de perçage, réduisant ainsi la durée de service du marteau rotatif.

PRECAUTION:

Quand on retire le goujon central et la plaque de guidage, mettre l’interrupteur sur la position d’arrêt (OFF) et débrancher la perceuse.

3.Démontage (Fig. 21)

Une autre méthode consiste à retirer la queue de la couronne du marteau rotatif à frapper fortement la tête de la queue de la couronne deux ou trois fois avec un marteau, tout en maintenant la couronne. Cela aura pour effet de desserrer le filetage et on pourra retirer la couronne.
