Rivet busters are powerful tools used in demanding applications, but like any equipment, they can encounter issues that disrupt performance. Troubleshooting common problems promptly ensures smooth operation, minimizes downtime, and extends the tool’s lifespan. Below are some practical steps to diagnose and fix two of the most common issues: the tool only blowing air or fluttering, and being unable to shut off the tool. 
 

If the tool only blows air or flutters:  

1. Check to see if the piston shows signs of wear, if worn, replace with new one. Check valve system for wear. In most cases, when worn, only the inner valve needs to be replaced.  
2. Disassemble and check all airways, especially in the valve system, for debris.  
 

If you cannot shut off the tool: 

1. Immediately turn off the air source, then disconnect the air supply. 
2. Disassemble, check throttle valve bushing for damaged O rings. 
3. Check Teflon valve for damage or wear, replace if necessary. 
4. On 4 bolt model, check the flapper valve, and if worn, flip it over and use the other side. If this has already been done, replace valve. 

Conclusion

Addressing common performance issues with rivet busters, such as air fluttering or failure to shut off, can be efficiently resolved with proper troubleshooting steps. Following these guidelines ensures optimal tool performance, reduces costly interruptions, and keeps your job site running smoothly. Always prioritize regular maintenance and timely replacements to keep your APT rivet busters in top condition.
