5 Signs Your Hydraulic Hammer Needs Service—Before It Fails on the Jobsite

Hydraulic hammers work under extreme pressure, which means wear and tear is inevitable. But waiting until your breaker completely fails can lead to expensive downtime, lost productivity, and rushed, costly repairs. The good news? Most issues give you warning signs—if you know what to look for.

One of the most common symptoms of a failing hammer is a noticeable drop in power. If your breaker isn’t hitting as hard as it used to, that’s often a sign of internal wear or nitrogen loss. Likewise, strange noises—clanking, rattling, or irregular vibrations—can signal loose components, worn bushings, or hydraulic imbalance.

Visible oil leaks, particularly near the seals or hose connections, are never normal and need immediate attention. Another key warning is accelerated tool wear. If you’re burning through chisels or moil points too quickly, the hammer’s alignment or bushing condition may be off. Lastly, if the hammer begins to misfire or "dry fire," it may be due to internal gas loss or a compromised valve system.
