Key specifications

• Power supply type: cordless 18V battery system

How to use

Fit a compatible SDS-plus chisel or bit into the tool holder according to the manufacturer's instructions and ensure the battery pack is correctly seated and charged. Select the appropriate chisel geometry for the task — wide flat chisels for tile and adhesive removal, pointed or narrow chisels for breakout and detail work. Operate the demolition hammer with a firm two-handed grip, start at low impact points if precision is required, and apply steady pressure while allowing the tool's percussive action to do the work. Periodically inspect the chisel for wear and replace or rotate as needed to maintain effective impact performance.

Recommendations

For safe and effective operation, use Bosch-approved batteries and accessories, wear appropriate personal protective equipment including eye and hearing protection, and follow local safety regulations. When working on reinforced concrete or very large demolition tasks, consider a higher-capacity mains-powered demolition hammer. Regularly check fastenings and the condition of the tool after heavy use to ensure continued reliable performance.
