When a rock drill experiences performance issues, quick troubleshooting can help restore functionality and prevent delays. Identifying the root cause—whether it’s a loss of power, air leakage, or the inability to shut off—ensures the tool is back in action as soon as possible. The following steps outline solutions for common problems encountered with rock drills. 
 

If you experience loss of power in the tool: 

1. Check side rod nuts to ensure they are tight on the tool. 
2. Flush cleaning solvent through the tool and then refill immediately with air tool oil or 10W equivalent. 
3. Disassemble and inspect ratchet pawls. If pawls show wear on the corners, they should be replaced. 
4. While the tool is disassembled, check the cleanliness of the valve and ensure cylinder ports are clear. 
 

If the tool is blowing air and will not function: 

1. Disassemble, check for broken piston or rifle bar, check the rifle nut condition. 
2. Check valve system for worn parts, replace if necessary. 
 

If you cannot shut off the tool: 

1. Immediately turn off the air source, then disconnect the air supply. 
2. Disassemble back head and inspect the throttle valve, replace throttle valve if worn. 

Conclusion

Proactive troubleshooting ensures your rock drill performs consistently and minimizes downtime on the job site. By regularly inspecting components, replacing worn parts, and maintaining clean airways, you can address issues before they become major problems. A well-maintained and promptly repaired tool will provide reliable service, keeping your operations running smoothly and efficiently.
