- The standard silencing feature allows you to use a GC S hammer on job sites in noise sensitive areas like neighborhoods or near hospitals where noise is regulated.
- The internal buffering system helps reduce machine vibration and increase noise suppression.
- Simple hammer design for easy maintenance and faster rebuilds to help lower owning and operating costs.
- Critical hydraulic components are shielded from damage inside the housing, helping decrease downtime on the job site.
- Standard onboard autolube provides continuous greasing as the hammer runs, eliminating the need for manual greasing.

- Verify the gas charge of the hammer without removing it from your machine.
