Saw Operations

Cutting Crown Molding

•Crown molding must be cut exactly to fit properly.

•There are two ways to cut crown molding: flat on table or angled to table and fence.

•Your miter saw has special miter detents of 31.6° left and right and a bevel detent of 33.9° for cutting crown molding flat on the table.

•These special detents angles have been designed into your compound miter saw for the standard crown molding used in the United States with the following angles:

52° between the back of the molding and the top flat

surface that fits against the wall.

38° between the back of the molding and the bottom flat surface that fits against the wall.

NOTE: These detents cannot be used with 45° crown molding.

•Even though these angles are standards, most rooms do not have angles of exactly 90°, therefore, you will need to fine tune your settings using the detent override and the vernier scale.

Opérations de la scie

Coupe de moulures en couronne

•Les moulures en couronne doivent être coupées exactement pour faire adéquatement.

•Il existe deux façons de couper les moulures en couronne : à plat sur la table ou à angle par rapport à la table et au guide.

•Votre scie à onglet possède des crans d’arrêt d’onglet spéciaux de 31,6° à gauche et à droite, et un cran d’arrêt de biseau de 33,9° pour couper les moulures en couronne à plat sur la table.

•Ces angles de crans d’arrêt spéciaux ont été incorporés dans votre scie à onglet composée pour les moulures en couronne standard utilisées aux États-Unis avec les angles suivants :

52° entre l’arrière de la moulure et la surface plate supérieure qui repose contre le mur.

38° entre l’arrière de la moulure et la surface plate inférieure qui repose contre le mur.

REMARQUE : Ces crans d’arrêt ne peuvent pas être utilisés avec les moulures en couronne de 45°.

•Bien que ces angles soient standard, la plupart des pièces n’ont pas d’angles d’exactement 90° ; vous devrez donc ajuster vos réglages à l’aide du court-circuitage de cran d’arrêt et de l’échelle graduée Vernier.

Operaciones de la sierra

Corte de moldura de techo

•La moldura de techo se debe cortar con precisión para que encaje adecuadamente.

•Hay dos maneras de cortar moldura de techo: horizontal sobre la mesa o en ángulo respecto a la mesa y al tope-guía.

•La sierra para cortar ingletes tiene retenes de inglete especiales de 31.6° a la izquierda y a la derecha y un retén de bisel de 33.9° para cortar moldura de techo en posición horizontal sobre la mesa.

•Estos ángulos de retén especiales han sido diseñados en la sierra para cortar ingletes compuestos para la moldura de techo estándar que se usa en los Estados Unidos con los siguientes ángulos:

52° entre la parte posterior de la moldura y la superficie superior plana que encaja contra la pared.

38° entre la parte posterior de la moldura y la superficie inferior plana que encaja contra la pared.

NOTA: Estos retenes no se pueden usar con moldura de techo de 45°.

•Aunque estos ángulos son estándar, la mayoría de las salas y cuartos no tienen ángulos de exactamente 90°. Por lo tanto, usted tendrá que ajustar con precisión las posiciones usando el sobrecontrol del retén y la escala Vernier.
