Hilti tools are programmed with specific service intervals based on usage hours. When a tool reaches its limit, a red indicator light activates, and the machine often stops working as a safety measure to prevent mechanical failure from worn parts. The SRT tool is required to clear these codes and reset the counter to factory settings. Compatible Tool Models The SRT tool is primarily used for heavy-duty rotary hammers and breakers, including: Rotary Hammers: TE 700-AVR TE 800-AVR TE 1000-AVR TE 1500-AVR Operation Procedure
