How to use

Insert a compatible Bosch 18 V battery into the tool according to the manufacturer’s instructions and ensure the battery is fully charged before starting work. Fit the appropriate SDS-plus drill bit or chisel, engage the chuck, and select the required speed or hammer mode using the tool’s controls. Start drilling with steady pressure, allowing the tool’s hammer action to do the work; avoid excessive force that can reduce bit life and battery runtime. For chiselling, switch to the chisel mode if available and position the chisel securely before applying brief, controlled impacts. Observe safe working distances and secure the workpiece as needed.

Usage recommendations

Use approved Bosch 18 V Professional batteries and a suitable charger to ensure optimal performance and safety. Wear appropriate protective equipment, including eye protection, hearing protection and dust masks when drilling or chiselling. For prolonged or heavy-duty tasks, select a higher-capacity battery to maintain runtime and monitor tool and bit temperature to prevent overheating.
