Always follow basic safety precautions when using hand tools to reduce the risk of personal injury. Failure to follow these instructions may result in injury or damage to the tool.

• Wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and hearing protection.
• Keep work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate the tool in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Keep children and bystanders away while operating the tool. Distractions can cause you to lose control.

4. Setup

Before using the rivet nut gun, ensure the correct mandrel is installed for the size of rivet nut you intend to use. The M6 mandrel is typically pre-installed.

4.1. Changing the Mandrel

1. Loosen the Rotary Knob: Turn the rotary knob counter-clockwise to loosen it and allow the mandrel to be removed.
2. Remove Current Mandrel: Pull out the currently installed mandrel from the tool head.
3. Insert New Mandrel: Select the appropriate mandrel size (M3, M4, M5, or M6) for your rivet nut. Insert the new mandrel into the tool head.
4. Insert the Bolt: Screw the corresponding bolt (part of the mandrel assembly) into the end of the mandrel.
5. Screw in the Nozzle: Screw the nozzle onto the tool head, ensuring it is finger-tight.
6. Tighten the Rotary Knob: Turn the rotary knob clockwise to secure the mandrel assembly firmly in place.

5. Operating Instructions

Follow these steps to properly install a rivet nut:

1. Prepare the Hole: Drill a hole in the material that matches the diameter of the rivet nut body. Ensure the hole is clean and free of burrs.
2. Load the Rivet Nut: Loosen the handles of the rivet nut gun. Thread the appropriate rivet nut onto the mandrel until it is snug against the nozzle.
3. Insert into Hole: Insert the rivet nut, with the gun attached, into the prepared hole in your workpiece.
4. Rivet the Nut: Firmly close the handles of the rivet nut gun. This action will compress the rivet nut, causing it to expand and grip the material from the backside, creating a secure thread. Apply steady pressure until the rivet nut is fully set.
5. Remove the Tool: Once the rivet nut is set, turn the rotary knob counter-clockwise to unthread the mandrel from the newly installed rivet nut. Remove the gun from the workpiece.

• Lubrication: Periodically apply a small amount of light machine oil to the pivot points and threads of the mandrel to ensure smooth operation.
• Storage: Store the rivet nut gun in its original case or a dry, secure location away from moisture and extreme temperatures. Ensure the handles are locked together for compact storage.
• Inspection: Regularly inspect the mandrels for wear or damage. Replace worn mandrels to prevent improper rivet nut installation.
