Pneumatic Rivet Gun Maintenance

At Dafra, we understand the importance of keeping your tools and air rivet guns in top-notch condition, ensuring optimal performance and longevity. Rivet guns are indispensable tools in various industries, offering efficient and precise fastening solutions.

Powered by a reliable air supply, these tools provide consistent performance, making them a preferred choice for professionals seeking high-quality riveting operations. Maintaining proper air pressure is crucial for optimal function, and Dafra can assist you with finding the right replacement parts to keep your rivet guns running smoothly.

Below are the essential checks that keep a pneumatic riveter working reliably, from routine cleaning through to wear inspection.

Understanding Your Rivet Gun

Imagine the pneumatic rivet gun as a powerful pulling tool. When you pull the trigger, compressed air drives the piston, which draws the jaws back so they clamp the mandrel and pull it through the rivet body.

This pulling action expands the rivet body against the material, creating a strong connection between the materials you're joining.

The gun has various parts: an air inlet (where air enters), a trigger, the piston that drives the pulling stroke, and a nose piece that holds the rivet in place.

Using Your Cordless Rivet Gun or Air Rivet Guns

Firstly, ensure that your rivet gun is fully charged if using a cordless model, or that your air compressor is properly connected and supplying adequate pressure if using an air-powered rivet gun. Next, select the appropriate size and type of rivet for your application, and insert it into the nosepiece of the rivet gun.

If using a cordless rivet gun, simply position the nosepiece over the pre-drilled hole in the materials to be fastened, and squeeze the trigger to initiate the riveting process.

For air rivet guns, connect the tool to the air compressor using a suitable air hose and fittings, and adjust the air pressure according to the manufacturer's recommendations. Once connected, follow the same procedure as with a cordless rivet gun, positioning the nosepiece over the hole and squeezing the trigger to drive the rivet. Holding the gun square to the work and supporting its weight through each stroke helps avoid needless wear.

General Air Rivet Gun Maintenance

Air rivet gun maintenance is essential for ensuring optimal performance and longevity of the tool. Regular cleaning, lubrication, and inspection of components are key practices to uphold in maintaining the efficiency and reliability of an air rivet gun.

By following these maintenance tips, you can ensure that your pneumatic rivet gun remains in optimal condition, providing reliable performance for all your riveting needs:

Regular Cleaning

After each use, it's crucial to clean your pneumatic rivet gun thoroughly. Use a clean, dry cloth to wipe away any debris, dust, or residue from the tool's exterior. Pay special attention to the rivet gun's nose piece and jaws, ensuring they are free from any obstructions that may affect performance.

Lubrication

Proper lubrication is essential for maintaining the smooth operation of your pneumatic rivet gun. Apply a few drops of pneumatic air tool oil to the gun's moving parts, including the trigger, piston, and air inlet, to prevent friction and wear. Be sure to follow the manufacturer's recommendations for the type and frequency of lubrication.

Inspect Air Hose and Fittings

Inspect the air hose and fittings regularly for any signs of damage, such as cracks, leaks, or wear. Replace any damaged components immediately to prevent air leaks, which can affect the rivet gun's performance and efficiency.

Check Air Pressure

Verify that the air pressure supplied to the pneumatic rivet gun is within the recommended range specified by the manufacturer. Using too high or too low air pressure can affect the tool's performance and may lead to premature wear or damage. Adjust the air pressure as needed using a suitable air pressure regulator.

Inspect Rivet Gun Components

Occasionally inspect all components of the pneumatic rivet gun, including the nosepiece, jaws, and mandrel collector system, for signs of wear or damage. Perform necessary pneumatic rivet gun adjustments to ensure proper functionality, and replace any worn or damaged parts promptly to maintain the tool's performance and safety.

Store Properly

When not in use, store your pneumatic rivet gun in a clean, dry environment away from moisture, extreme temperatures, and corrosive substances. If pneumatic rivet gun disassembly is necessary for cleaning or repair, follow the manufacturer's instructions carefully to ensure proper reassembly and safe operation.

Additionally, use a protective case or cover to prevent dust and debris from accumulating on the tool.

Before You Start

Work through these three checks before you service or operate the tool:

• Disconnect the air supply before inspecting internal parts.
• Empty the mandrel collector so it doesn't strain the tool.
• Wear eye protection while servicing or operating the tool.

Wear Parts to Watch

Three components wear fastest on a pneumatic riveter, so check each one regularly:

• Jaws – worn jaws are a common reason a rivet gun won't grip the mandrel.
• Nosepiece – inspect for wear, since it experiences repeated force with each rivet you set.
• O-rings and seals – air leaks or a drop in pulling power usually mean these have perished. Our guide to pneumatic rivet gun spare parts covers what to check and when to replace it. See our pneumatic rivet tools range for more detail.

FAQs

What happens when your air rivet gun is not working?

If your air rivet gun won't fire or won't grip the mandrel, check each likely cause in turn and fix what you find before moving on. This may involve inspecting the air supply, cleaning and lubricating the tool, checking for damaged or worn parts, and ensuring correct usage and operation. If the problem persists, it may be necessary to seek professional repair or replacement of the rivet gun.

What are common air rivet gun problems?

The most common pneumatic rivet gun problems include air source leaks, jamming, misfiring, air pressure fluctuations and stuck mandrel. It's best to undergo regular maintenance and cleaning to avoid problems with the compressor, cylinder or rivets.
