The Hilti SRT (Service Reset Tool) is a specialized electronic device developed to interact with the internal electronics of Hilti power tools. When a Hilti tool is sent for service or reaches its maintenance hour limit, the onboard electronics lock the motor to protect the tool, causing the red light to activate.
Instead of waiting for a service center, technicians can reset tools instantly, putting them back on the job site immediately. hilti srt service reset tool top
