3. Operating Instructions
Selecting Operating Mode
The DCH133B features a rotating dial to select the appropriate operating mode for your application:
- Drill Mode: For drilling into wood, metal, and plastics without hammer action.
- Hammer Drill Mode: For drilling into concrete, masonry, and stone with combined rotary and hammer action.
- Chip Mode (Chiseling): For light chiseling and chipping applications in concrete and masonry.
Drilling Concrete/Masonry
When drilling into concrete or masonry, ensure you use appropriate SDS Plus drill bits. Apply steady, firm pressure to the tool. Allow the hammer action to do the work; excessive force is not necessary and can reduce efficiency or damage the bit. For optimal dust management, consider using a compatible dust extractor (sold separately).

4. Maintenance
Cleaning
Regularly clean the tool's ventilation slots to prevent overheating. Use a soft brush or dry cloth to remove dust and debris. Do not use water or chemical cleaning agents.
