(4)Unir la placa guía con la barrena tubu- lar 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. 19)

2. Modo de taladrar (Fig. 20)

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

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

Presionar ligeramente de forma per- pendicular 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.

PRECAUCIÓN:

Cuando se quite el pasador central y la placa guía, poner el interruptor en la posición de apagado (OFF) y desconectar el enchufe de la toma de alimentación.

3.Desmontaje (Fig. 21)

Como otro método, quitar la espiga de la barrena tubular del martillo giratorio y golpear fuertemente la cabeza de la espiga de la barrena tubular dos o tres veces con un martillo sujetanto la punta de la barrena. La parte roscada se aflojará y la barrena tubular podrá quitarse.
