Astro Pneumatic Super Duty Air Hammer & Riveter - 0.5 in Shank

A compressor capable of delivering at least 3.1 CFM average and 12.5 CFM at 90 PSI is recommended for optimal performance.

Apply a few drops of quality air tool oil to the air inlet before each use and every few hours of continuous operation.

While versatile, its heavy-duty nature makes it best suited for industrial, off-road, and truck applications. For delicate automotive body panels, a lighter-duty air hammer might be more appropriate.

The Astro Pneumatic 4980 features a 0.498" (or approximately 0.5 inch) shank.

It is compatible with standard 0.498" shank air hammer accessories such as chisels, punches, and rivet sets.

Always wear safety glasses or a face shield, hearing protection, and gloves. Ensure the work area is clear and the workpiece is securely fastened.

Clean external debris after each use. For internal maintenance, follow lubrication guidelines and inspect regularly for wear or damage.

Check air compressor pressure and output (ensure it meets 90 PSI and required CFM). Inspect air hose for kinks or leaks. Ensure the tool is adequately lubricated.

Check for moisture or debris in the air line. Ensure the air inlet is not obstructed. Allow the tool to cool if it has been used continuously under heavy load.

Ensure all connections are tight. Use the tool on appropriate surfaces; excessive vibration can occur if the workpiece is not stable. Always wear anti-vibration gloves.

Inspect the tool for cracks or damage. Ensure all seals and O-rings are intact. Contact customer support if damage is found.
