Air Supply Requirements
The performance and longevity of your air hammer depend on a clean, dry, and adequately supplied air source.
- Compressor: Refer to the specifications section for recommended compressor tank sizes based on usage (continuous, intermittent).
- Working Pressure: Maintain a working pressure of 90 PSI for optimal performance.
- Air Inlet: The tool features a 1/4" NPT air inlet.
- Recommended Hose Size: Use a 3/8" ID air hose for efficient air flow.
- Air Filtration: Install an in-line air filter to prevent moisture and debris from entering the tool.
Tool Connection
- Ensure the air compressor is turned off and the air line is depressurized.
- Apply thread sealant tape to the 1/4" NPT air inlet fitting on the tool.
- Connect a quick-connect coupler (not included) to the air inlet.
- Connect the air hose from your compressor to the quick-connect coupler on the tool.
Installing Chisels/Attachments
The air hammer features a quick-connect chuck for easy installation and removal of chisels and other attachments.
- Ensure the air supply is disconnected from the tool.
- Pull back the quick-connect chuck collar.
- Insert the shank of the desired chisel or attachment into the chuck.
