Chipping hammers are essential tools for heavy-duty tasks, but like any equipment, they can encounter performance issues. Knowing how to troubleshoot these problems will help you quickly restore the tool's functionality and avoid unnecessary downtime. This guide outlines key steps to address common issues such as erratic operation, reduced impact, and the inability to shut off the tool. 
 

If the tool runs erratically: 

1. On the 260 series tools, check all nuts to ensure they remain tight on the tool. 
2. On the 650 series tools, check the handle is tight and the locking ring is correctly fitted. 
3. Flush cleaning solvent through the tool and then refill immediately with air tool oil or 10W equivalent. 
4. If tool still runs erratically, disassemble and check the cleanliness of the valves, In addition, check for plugged cylinder ports. 
5. Check for wear in the front bushing (round or hexagon), if worn, this will allow air to escape excessively from the tool. 
 

If the tool is not hitting hard enough: 

1. Check all the nuts, bolts and handles to ensure they are tight on the tool. 
2. If all nuts, bolts and handles are tight, then check for wear on internal parts, if worn, the Parts should be replaced. 
3. Check clearances between piston and cylinder bore carefully. Check front bushing for wear (round or hexagon). 
 

If you cannot shut off the tool: 

1. Immediately turn off the air source, and then disconnect the air supply 

Conclusion

Proactively troubleshooting your chipping hammer ensures it stays reliable and effective on the job. Regular inspections, timely part replacements, and secure fittings are essential for maintaining peak performance.
