2. Safety Information
Always prioritize safety when operating power tools. Read and understand all instructions before use.
- Eye Protection: Always wear safety glasses (included) to protect against flying debris.

- Work Area: Keep your work area clean, well-lit, and free from obstructions.
- Proper Attire: Avoid loose clothing or jewelry that could get caught in moving parts.
3. Setup
- Unpacking: Carefully remove the nailer and all accessories from the carrying BMC box. Inspect for any damage.
- Connecting to Air Supply:
- Attach a 6-mm NPT standard quick plug adapter to the air inlet of the nailer.
- Connect the nailer to your air compressor using a suitable air hose. Ensure the air compressor is set to the recommended operating pressure of 60-120 PSI.

- Positioning: Hold the nailer firmly with both hands if possible. Place the Work Contact Element (WCE) firmly against the workpiece where you intend to drive a nail.
- Driving Nails: Once the WCE is pressed against the surface, pull the trigger to drive a nail. Release the trigger after each nail.
- Depth Adjustment: If nails are not driven to the desired depth or are driven too deep, adjust the tool-free depth mechanism as needed.
