6. Operating Instructions
6.1 Power Connection
Connect the power cord to a suitable electrical outlet. Ensure the voltage matches the drill's requirements.
6.2 Selecting Operating Mode
Use the mode selector switch (typically located on the top or side of the drill) to choose between:
- Rotary Drilling: For drilling in wood, metal, plastics, and ceramics.
- Hammer Drilling: For drilling in masonry, concrete, and stone.
6.3 Adjusting Speed
The drill features an adjustable speed control dial. Rotate the dial to set the maximum speed for your application. Lower speeds are suitable for larger drill bits, softer materials, or screwdriving. Higher speeds are for smaller bits and harder materials.
