2. Important Safety Instructions
Always follow basic safety precautions when using electrical tools to reduce the risk of fire, electric shock, and personal injury.
- Work Area Safety: Keep your work area clean and well-lit. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Electrical Safety: Power tool plugs must match the outlet. Never modify the plug. Avoid body contact with earthed or grounded surfaces. Do not expose power tools to rain or wet conditions.
- Personal Safety: Always wear eye protection, hearing protection, and suitable work gloves. Dress properly; avoid loose clothing or jewelry. Secure long hair.
- Tool Use and Care: Do not force the power tool. Use the correct tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
- Kickback Prevention: Always maintain a firm grip on the tool. Be prepared for sudden reactions when the drill bit binds.
- Dust Extraction: When drilling, especially in concrete, significant dust is generated. Use appropriate dust extraction systems and wear a dust mask.

4. Setup
4.1 Attaching the Auxiliary Handle
Loosen the auxiliary handle by twisting it counter-clockwise. Slide it over the chuck and position it to your desired angle for optimal control and comfort. Tighten by twisting clockwise until secure.
4.2 Inserting Drill Bits/Chisels
- Clean the shank of the SDS-plus bit and apply a small amount of the included grease to the end.
- Pull back the chuck sleeve.
- Insert the bit into the chuck until it clicks into place.
- Release the chuck sleeve. Pull on the bit to ensure it is securely locked. The bit should have a slight axial play; this is normal for SDS-plus systems.
4.3 Power Connection
Ensure the tool's voltage rating matches your power supply (230V). Plug the power cord into a grounded electrical outlet. Always use a residual current device (RCD) for added safety.
5. Operating Instructions
5.1 Selecting Operating Mode
Rotate the mode selector switch to choose the desired function:
- Drilling (Rotary Only): For drilling in wood, metal, or plastic. No hammering action.
- Hammer Drilling (Rotary with Hammer): For drilling in concrete, brick, and stone. Both rotation and hammering action are active.
- Chiseling (Hammer Only): For chiseling, breaking, or demolition work. Rotation is disengaged, only hammering action.
5.2 Starting and Stopping
To start the tool, press the trigger switch. To stop, release the trigger switch. For continuous operation, press the trigger and then press the lock-on button. To release, press the trigger again.
5.3 Speed Control
The tool features variable speed control. The drilling/hammering speed can be adjusted by the pressure applied to the trigger switch. For precise starting, begin with low speed and gradually increase.
5.4 Working with the Tool
Apply moderate pressure to the tool. Do not force it, as excessive pressure can reduce efficiency and damage the tool or bit. Allow the tool's hammering action to do the work. For optimal performance and tool longevity, allow the tool to rest after prolonged continuous use, especially during heavy-duty applications.
6. Maintenance and Care
6.1 Cleaning
After each use, clean the tool's ventilation slots and housing with a soft brush or compressed air. Do not use water or chemical cleaning agents. Regularly clean the chuck to prevent dust and debris buildup.
6.2 Lubrication
Apply a small amount of the provided grease to the SDS-plus bit shank before insertion to ensure smooth operation and reduce wear on the chuck.
6.3 Storage
Store the tool in a dry, secure place, out of reach of children. Protect it from direct sunlight, extreme temperatures, and moisture. It is recommended to store the tool in its original carrying case.
