Setup
1. Connecting to Air Supply
- Ensure your air compressor is off and the air hose is depressurized.
- Connect the 1/4" air pump pipe connector on the tool to your air hose.
- Set your air compressor to the recommended operating pressure (refer to tool specifications or manufacturer guidelines for pneumatic tools).
- Turn on the air compressor.
2. Selecting and Installing Mandrels
The tool comes with interchangeable mandrels for different rivet nut sizes (M4, M5, M6, M8, M10). Always select the mandrel that matches the rivet nut you intend to use.

- Unscrew the Mandrel Part: Rotate the existing mandrel part counter-clockwise to remove it.
- Unscrew the Nut Sleeve: Rotate the nut sleeve counter-clockwise to detach it.
- Use Wrenches: If necessary, use the provided wrenches to loosen or tighten the mandrel components. One wrench is used for fixing the mandrel part, and the other wrench is rotated counter-clockwise to loosen the nut sleeve.
- Replace Mandrel: Insert the desired mandrel (M4-M10) into the tool and tighten all components securely by rotating clockwise. Ensure the nut sleeve is firmly attached.
Operating Instructions
Follow these steps for proper operation of the pneumatic rivet nut gun:
Image: Step-by-step guide for operating the rivet nut gun.
- Select Rivet Nut: Choose the appropriate rivet nut size that matches the installed mandrel and your application.
- Load Rivet Nut: Thread the selected rivet nut onto the mandrel until it is snug.
- Position Tool: Place the pneumatic gun on the target workpiece, ensuring the rivet nut is properly seated in the pre-drilled hole.
- Initiate Riveting: Press the start switch (trigger) to activate the pneumatic mechanism. The tool will pull the mandrel, deforming the rivet nut to create a secure fastening. The quick-release air valve ensures rapid cylinder return for efficient operation.
- Release Riveted Nut: Once the rivet nut is installed, turn the nut push-out knob to separate the mandrel stem from the riveted nut.
- Repeat: For subsequent installations, repeat steps 2-5.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your pneumatic rivet nut gun.
- Cleaning: Keep the tool clean and free from debris. Wipe down the exterior with a clean, dry cloth after each use.
- Lubrication (Oil Filling): Periodically lubricate the internal pneumatic components. To access the oil filling hole, remove the bottom cover of the tool. Use a few drops of pneumatic tool oil. Refer to the 'Product Overview' section for the location of the oil filling hole.
- Mandrel Inspection: Regularly inspect mandrels for wear or damage. Replace worn mandrels to ensure proper rivet nut installation and prevent damage to the tool.
- Air Line Maintenance: Ensure your air supply line is clean and dry. Use an air filter/regulator/lubricator (FRL unit) to prevent moisture and contaminants from entering the tool.
- Storage: Store the tool in its plastic case in a dry, clean environment when not in use.
Troubleshooting
If you encounter issues with your Proster Pneumatic Rivet Nut Gun, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool does not operate or has low power. | Insufficient air pressure or air supply. | Check air compressor pressure and ensure adequate air flow. Verify air hose connections are secure. |
| Rivet nut does not install correctly or strips. | Incorrect mandrel size or worn mandrel. | Ensure the mandrel matches the rivet nut size. Replace worn or damaged mandrels. |
| Air leakage from the tool. | Loose connections or damaged seals. | Check all air connections for tightness. Inspect the screw sleeve for damage to the rubber ring. |
| Mandrel stem gets stuck in the riveted nut. | Nut push-out knob not used correctly or internal mechanism issue. | Ensure the nut push-out knob is fully turned after riveting. If the problem persists, internal lubrication may be needed. |
