- Install the Nozzle: Unscrew the current nozzle (if any) from the front of the rivet gun. Screw the selected nozzle firmly into place.
- Select the Correct Drill Bit: Use an HSS drill bit that matches the diameter of your rivet for the pilot hole. The kit provides corresponding drill bits.

5. Operating Instructions
Follow these steps to operate your LIBRATON Rivet Gun:
- Drill a Hole: Using the appropriate HSS drill bit, drill a hole through the materials you wish to join. The hole size should match the rivet diameter.
- Insert Rivet: Insert the rivet into the rivet gun's nozzle.
- Position the Rivet: Place the rivet head into the drilled hole, ensuring the materials are flush.
- Apply Pressure: Firmly press the handles of the rivet gun together until the rivet breaks off, indicating a secure connection. The ergonomic handle design provides a 50% force-saving advantage.
- Collect Shafts: The integrated shaft container at the rear of the tool collects spent rivet shafts, preventing clutter and ensuring a clean workspace.

Regular maintenance ensures the longevity and optimal performance of your rivet gun:
- Cleaning: After each use, empty the shaft container. Wipe down the tool with a clean, dry cloth to remove any debris or dust.
- Lubrication: Periodically apply a small amount of light machine oil to the moving parts and pivot points to ensure smooth operation.
- Storage: Store the rivet gun and its accessories in the provided blow-molded case in a dry, clean environment to protect it from damage and corrosion. Use the safety lock for secure storage.

7. Troubleshooting
If you encounter issues while using your rivet gun, refer to the following common problems and solutions:
- Rivet Gets Stuck: Ensure the correct nozzle size is used for the rivet. A mismatch can cause the rivet to jam. Also, verify the drill hole size matches the rivet diameter.
- Rivet Does Not Set Properly: Apply firm and consistent pressure to the handles until the rivet mandrel breaks. Ensure the materials being joined are properly aligned and clamped if necessary.
- Difficulty Squeezing Handles: This tool is designed for heavy-duty use and may require significant force. Ensure the tool is clean and lubricated. For very large rivets or tough materials, two-handed operation may be necessary.
- Spent Mandrels Not Collecting: Check if the shaft container is properly closed and not obstructed. Empty the container regularly.

- Wear appropriate personal protective equipment, including safety glasses, to protect against flying debris.
- Keep hands and fingers clear of the riveting mechanism during operation.
