To remove the core bit, follow the procedures 1 or 2.
1.Rotate the change lever to the 
position. Then rest the core bit on the concrete and turn the tool on. The core bit will come loose from the hammering action.
2.Hold the adapter with the wrench, insert the rod (optional accessory) 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 
position and resume drilling.
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 bit”.
MAINTENANCE
CAUTION:
•Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
