Product Information
Full details
This US PRO Air Hammer Chisel is designed for automotive and workshop professionals needing a durable tool for heavy-duty tasks. Its key benefit is the long-life alloy steel construction combined with a heat-treated piston for reliable performance. A potential caveat is its requirement for a minimum air consumption of 4 CFM, necessitating a capable air compressor.

FAQs
What is the purpose of the different chisels included?
The set includes a taper punch for general breaking, a ripping chisel for scraping and rough demolition, a tailpipe cutter for efficient exhaust pipe removal, and a spot weld breaker specifically designed for automotive bodywork to separate spot-welded panels.
What type of air compressor is recommended?
You will need an air compressor that can consistently supply at least 4 CFM (Cubic Feet per Minute) at 90 psi to operate this air hammer effectively.
How often should I lubricate the air hammer?
It is recommended to add a few drops of air tool oil into the air inlet before each use to ensure proper internal lubrication and prolong the tool's life.
Can I use chisels with a different shank size?
No, this air hammer is designed for a 10.2mm chisel shank. Using chisels with a different shank size can result in poor performance, damage to the tool, or the chisel becoming dislodged.
What maintenance is required for the coil spring retainer?
Periodically check the coil spring retainer for signs of wear or damage. Ensure it springs back effectively to hold the chisel securely. Replace the retainer if it becomes weak or broken.
How do I clean the air hammer?
After disconnecting from the air supply, wipe the exterior with a dry or slightly damp cloth. Remove any debris from the barrel and around the chisel area. Avoid using solvents that could damage the tool's components.
What does BPM stand for?
BPM stands for Blows Per Minute, indicating the speed at which the hammer strikes. This model delivers 4,500 BPM for rapid material removal.
Troubleshooting
Air hammer not striking or is weak.
Check air pressure is at 90 psi. Ensure air hose connection is secure and leak-free. Verify air compressor is delivering sufficient CFM (4 CFM minimum). Ensure the chisel is properly seated and the retainer is engaged. Add air tool oil if not recently lubricated.
Chisel is loose or falling out.
Ensure the coil spring retainer is properly engaged around the chisel shank. Check the retainer spring for damage or wear; replace if necessary. Make sure the chisel shank is not bent or damaged.
Excessive vibration or noise.
Ensure proper lubrication with air tool oil. Check that the chisel is fully inserted and secured. Inspect the tool for any loose parts or damage. Verify the correct chisel type is being used for the material.
Air leaks from the tool.
Inspect the air inlet connection for tightness and damage. Check seals and O-rings within the tool body for wear or degradation; professional servicing may be required.
