You would need to:
The Hilti SRT (Service Reset Tool) is a specialized electronic device used to reset the internal service counter and deactivate the "red light" service indicator on high-end Hilti power tools.
Hilti tools are programmed with specific service intervals; once a tool reaches its maximum service hours, a red light activates, and the machine often stops functioning to prevent damage and ensure safety. The SRT tool is required to manually clear these error codes and return the tool to active operation after it has been properly maintained. Key Features and Specifications
Service Counter Reset: Resets the internal electronics so the machine functions as if it were newly serviced.
Indicator Removal: Successfully removes the red service light that prevents tool use.
Compatibility: Specifically designed for SRT-compatible Hilti models (e.g., TE 70, TE 76, TE 706 AVR).
Diagnostic Port Integration: The tool typically plugs into a designated reset port or uses an optical interface (pushing the sensor against the light) to communicate with the tool's PCB.
Success Feedback: Many SRT devices feature a green light to indicate a successful reset. How to Use the Hilti SRT Tool hilti srt service reset tool top

Connection: Insert the SRT device into the toolās designated reset port or align its sensor with the service light.
Reset Trigger: Press and hold the reset button on the SRT tool for approximately 5 to 10 seconds until the display confirms the reset or the indicator clears.
Verification: Power the Hilti tool back on to confirm the red light is gone and the machine is operational. Market Availability and Pricing
While Hilti typically performs these resets at their own service centers as part of official maintenance, third-party reset tools and services are available on the secondary market:

The red light was the end of the line for ās favorite Hilti breaker
. In the middle of a high-stakes demolition job, the tool had simply stopped. It wasn't broken; it was just "time." Hilti tools are programmed with strict service intervals, and once those hours are clocked, the internal electronics trigger a lockout to ensure maintenance like regreasing or brush replacement is performed.

The primary function of the SRT is to perform a mandatory reset following preventive maintenance or repair. The SRT 6āA22 nailers are gas-spring/diesel cycle tools that track piston service life. Once the tool reaches a predefined shot count (e.g., 100,000 cycles), it locks out operation until a service reset is applied.
