6. Operating Instructions
6.1 Selecting Operating Mode
Rotate the mode selector switch to choose the desired operating mode:
- Hammer Drilling: For drilling in concrete and masonry with impact.
- Drilling: For drilling in wood, metal, ceramics, and plastic without impact. Use the interchangeable keyless chuck for cylindrical drill bits.
- Chiseling: For light chiseling work (e.g., removing tiles, light demolition). Engage the rotation stop for this mode.
6.2 Starting and Stopping
- To start the tool, press the trigger switch.
- For continuous operation, press the lock-on button while the trigger switch is pressed.
- To stop the tool, release the trigger switch. If locked on, press and release the trigger switch briefly.

- Use the direction of rotation switch to select forward or reverse rotation. This is typically located near the trigger.
6.4 Working Tips
- Apply moderate pressure; let the tool do the work. Excessive pressure will not speed up drilling and can damage the tool or bit.
- When drilling deep holes, periodically withdraw the drill bit to clear debris.
- For chiseling, ensure the rotation stop is engaged.
- Always ensure the workpiece is securely clamped or stabilized.
