5. Operating Instructions
Once the Power Change Plus Adapter and desired accessories are securely attached, you can begin drilling. Always ensure the workpiece is stable and clamped if necessary.
- Select Drill Mode: Set your rotary hammer drill to the appropriate mode for drilling (e.g., rotary drilling for wood/metal, hammer drilling for masonry if using a suitable hole saw).
- Position the Tool: Place the pilot drill bit at the desired drilling location on the workpiece. Apply steady, even pressure.
- Begin Drilling: Start the drill at a low speed and gradually increase as the hole saw begins to cut into the material. Maintain consistent pressure.
