How to repair a rivet gun. The know-how to service your cordless rivet gun or air riveter.

Rivet guns are generally known as reliable tools, like any other equipment, they need correct set-up and regular maintenance. In today’s article, we’ll look at a few simple tips and tricks to keep your riveter in good working order. Cordless rivet guns and air rivet tools are easy to operate and normally provide hassle-free installations. The starting point of any tool purchase is to refer to the operating manual before use. Ensure you have the right gun for the type of rivets. Are you using general purpose rivets, like multi-grip rivets or heavy-duty structural rivets like the Huck® Magna-Lok® rivet? Does the nose tip's opening match the rivet’s pin diameter? Is your air compressor in good working order? Do you know the air pressure? These questions highlight the importance of spending a bit of time understanding the tool. Many of these questions can only be addressed by the type and model of the gun and the operating manual. Before we jump into rivet gun troubleshooting guide let’s touch base with the different power types of rivet guns and their key features.   

Air Rivet Gun.

Air rivet guns are ideal for medium to high production operations where there is repetitive rivet installation. They are powerful, reliable, and provide consistent results for the installation of rivets. Air rivet guns are extremely fast and require a well-maintained compressor to provide back-up power. This makes them a little impractical on construction sites or in remote locations. 

Cordless Rivet Guns.

Battery or cordless rivet guns are becoming more sophisticated and increasingly popular. Lithium-ion batteries are lighter than older-style batteries and often hold more charge, making them a hassle-free option for building sites and sometimes fabrication workshops. We have a big range of cordless rivet guns from Pop®, Gesipa® and our very own battery riveter that has been lab-tested for quality and value.

Manual Riveting Tools.

For the weekend warrior who occasionally installs rivets, a manual pop rivet-tool is the go-to option. If you need to repair a gutter or add an accessory to a vehicle, a short-handled plier hand riveter will probably do the job. There are numerous hand rivet tool options including the concertina rivet tool which is commonly known as the lazy tong riveter because you can install rivets with one hand, through to the long handle lever option where two hands are required to install a rivet. These are great for larger diameter  or stainless steel rivets.

General Maintenance Steps (All Rivet Tools)

Before you use a rivet tool, ensure the rivet pin-tail size matches the nose tip and sometimes jaw types might be a consideration if you have a tool that installs both standard and structural rivets.  

1. Clean After Use

   • Wipe off dust, grease and metal shavings from the jaws with a clean cloth.

   • Use compressed air to blow out dust from crevices.

2. Lubricate Only Where Recommended

   • Only apply lubricant where specified in the manufacturer’s operating manual.

   • Do not lubricate cordless rivet guns unless the manual specifically instructs you to do so.

   • Over-lubrication can attract swarf, dust and debris, and may cause tool damage.

3. Inspect for Wear

   • Check jaws, nosepieces, and springs for wear or damage.

   • Replace worn parts immediately to avoid malfunction or damage.

4. Tighten Screws & Fasteners

   • Vibrations can loosen screws - regularly check and tighten all fasteners.

Specific Maintenance by Tool Type

Hand Rivet Tool

• Jaw Maintenance: Inspect and clean the jaws regularly.

• Nosepieces: Unscrew and clean; keep free of debris.

• Storage: Store in a dry place to prevent rust.

Air Rivet Gun

• Air Supply: Use clean, dry compressed air. Use a filter and lubricator.

• Oiling: Only oil the tool as recommended by the manufacturer. Too much oil can attract debris and may cause internal damage.

• Air Pressure: Ensure the compressor is delivering the recommended PSI (check manual).

• Hose Check: Inspect air hose for cracks or leaks.

Battery / Cordless Rivet Gun

• Battery Care: Keep batteries charged and store in a cool, dry place.

• Motor Maintenance: Listen for strange noises; may indicate motor or gear issues.

• Dust Protection: Keep the ventilation areas clean to help prevent overheating.

Regular Replacement Parts

• Jaws (grippers)

• Springs

• Nosepieces
