1. Montaje

PRECAUCIÓN:

Cerciorarse de poner el interruptor de la alimentación en la posición de apagado (OFF) y de desconectar el enchufe de la toma de alimentación.

(1)Montar la barrena tubular en su espiga. (Fig. 15)

Lubricar la rosca de la espiga de la barrena tubular para facilitar el desmontaje.

(2)Montar la espiga de la barrena tubular en el martillo giratorío. (Fig. 16)

(3)Insertar el pasador central en la placa guía hasta que se pare.

(4)Unir la placa guía con la barrena tubular y girar la placa guía hacia la izquierda o hacia la derecha de forma que no se caiga a pesar de estar indicando hacia abajo. (Fig. 17)

2.Modo de taladrar (Fig. 18)

(1)Conectar el enchufe a la toma de alimentación.

(2)El pasador central se ha instalado un resorte.

Presionar ligeramente de forma perpendicular hacia la pared o hacia el pared o hacia el suelo. Procurar que toda la punta de la barrena tubular esté en contacto con la superficie a taladrar y luego, empezar la operación.

(3)Al taladrar aproximadamente 3/16" (5 mm) en profundidad, la posición del agujero queda ya establecida. Quitar el pasador central y la placa guía de la barrena tubular y seguir taladrando.

(4)La aplicación de una fuerza excesiva acelerará el cumplimiento del trabajo, pero deteriorará la punta de la broca reduciendo la duración del martillo giratorio.
