HOW TO USE THE CORE BIT

When boring penetrating large hole use the core bit. At that time use with the center pin and the core bit shank provided as optional accessories.

1. Mounting

CAUTION:

Be sure to turn power OFF and disconnect the plug from the receptacle.

(1)Mount the core bit to the core bit shank. (Fig. 10)

Lubricate the thread of the core bit shank to facilitate disassembly.

(2)Mount the core bit shank to the rotary hammer. (Fig. 11)

(3)Insert the center pin into the guide plate until it stops.

(4)Engage the guide plate with the core bit, and turn the guide plate to left or right so that it does not fall even if it faces downward. (Fig. 12)

2. How to bore (Fig. 13)

(1)Connect the plug to the receptacle.

(2)A spring is installed in the center pin. Push it lightly to the wall or the floor straight. Connect all over the surface of the core bit tip and start operating.

(3)When boring about 3/16" (5 mm) in depth the position of the hole will establish. Bore after that removing the center pin and the guide plate from core bit.

(4)Application of excessive force will not only expedite the work, but will deteriorate the tip edge of the drill bit, resulting in reduced service life of the rotary hammer.

CAUTION:

When removing the center pin and the guide plate, turn OFF the switch and disconnect the plug from the receptacle.
