3. Operating Instructions
Function Selector (Percussion/Rotation):
Your hammer drill features a selector switch to choose between standard rotation (drilling) and percussion (hammer drilling) modes. Use rotation mode for drilling into wood, metal, and plastics. Use percussion mode for drilling into masonry and concrete.
