Allow the tool to cool during extended continuous operation and replace batteries as needed to maintain performance.

Recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and dust mask when drilling into concrete or masonry. For best results when drilling to the maximum diameter, start with a pilot hole and consider using progressive speeds. Charge batteries fully before intensive jobs and store the tool in a dry, dust-free environment between uses to prolong service life.
