When a tool malfunctions, the SRT Top can read "Fault Codes" stored in the tool’s memory. This allows technicians to pinpoint issues—such as a short circuit, switch failure, or overheating event—without disassembling the tool first.
Disconnect the SRT. Unplug the rig for 10 seconds to allow the ECU to cycle. Plug it back in. The service light should now be extinguished, and the trigger should activate the motor normally.

It is important to note that Hilti is pushing its ON!Track fleet management system. With an ON!Track Bluetooth module installed, the SRT becomes obsolete because you can reset service intervals via the mobile app.
So, why buy the SRT Top?
The Hilti SRT (Service Reset Tool) is a proprietary, handheld electronic device designed exclusively for Hilti’s latest generation of DD (Diamond Drill) coring systems. Unlike older models that used manual reset switches, the SRT is a digital interface that communicates directly with the tool’s onboard ECU (Engine Control Unit).
The "Top" in the keyword often refers to the Top-End model or the Top-performing version of this reset tool, which includes expanded memory for multiple tool models and firmware updates.
Modern Hilti tools track their usage hours and maintenance requirements electronically. When a tool reaches a specific number of operating hours, it may lock or display a service warning. hilti srt service reset tool top
The primary function of the SRT is to perform a mandatory reset following preventive maintenance or repair. The SRT 6‑A22 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.
