To remove the core bit, follow the procedures (1) or (2).

1)Rotate the change lever to the posi- tion. Then rest the core bit on the con- crete and turn the tool on. The core bit will come loose from the hammering action.

2)Hold the adapter with the wrench, in- sert the rod into the hole in the core bit and tap with a hammer to unscrew.

[When not using the center bit]

Screw the core bit on the adapter. Install the adapter with the core bit in the tool in the same manner as a drill bit.

Rotate the change lever to the position. Rest the core bit on the concrete and turn the tool on. Once the core bit has cut a shallow groove into the concrete, rotate the change lever to the Ti position and resumedrilling.

NOTE:

No problem is caused even if the core bit unscrews slightly during brief use since the core bit rotates in the tightening direction.

To remove the core bit, follow the same removal procedures covered in [when using the center bit1.
