Frequently Asked Questions
What air pressure (PSI) is required to run the UW-AH190?
What air pressure (PSI) is required to run the UW-AH190?
For optimal performance, we recommend operating at 90 PSI. This ensures the tool delivers its full 3,500 BPM impact force while maintaining the longevity of the internal heat-treated piston.
Does this kit work with standard 0.401-inch shank chisels?
Does this kit work with standard 0.401-inch shank chisels?
Yes! The UW-AH190 is designed to be compatible with standard 0.401-inch (approx. 10mm) round shank chisels, giving you the flexibility to use your existing bits or specialized aftermarket attachments.
How does the "Quick Change Retainer" differ from a standard spring retainer?
How does the "Quick Change Retainer" differ from a standard spring retainer?
Standard springs can be difficult to install, lose tension over time, and can be dangerous if they pop off. Our Self-Locking Quick Change Retainer allows for tool-free, one-handed bit swaps in seconds. It provides a much more secure lock, significantly improving safety and efficiency.
Is this air hammer suitable for removing rusted suspension parts?
Is this air hammer suitable for removing rusted suspension parts?
Absolutely. With its 190mm compact barrel and high-velocity impact, it is specifically designed for automotive tasks like popping ball joints, shearing rusted bolts, and removing stubborn bushings in tight spaces.
What kind of maintenance does the tool require?
What kind of maintenance does the tool require?
To keep the tool running smoothly, we recommend adding 2–3 drops of pneumatic tool oil into the air inlet before each use. This lubricates the heat-treated piston and prevents internal corrosion.
Does the package include the carrying case?
Does the package include the carrying case?
Yes, the kit comes complete with a high-density, impact-resistant blow-mold case that fits the air hammer, the quick-change retainer, and all 5 chisel bits for easy storage and portability.
Why is the 190mm model better than larger models?
Why is the 190mm model better than larger models?
The UW-AH190 is the "sweet spot" for most mechanics. While it delivers heavy-duty power, its shorter length allows you to reach into wheel wells and engine bays where larger 250mm hammers simply won't fit.
