Hi . The solution offered by rowdy (pull the trigger and hold it until light goes out) will only work on older machines, the newer machines have more complex electronics that need reseting using an optical reader which plugs into a PC , you will also need the Hilti ODA Software. this is not available to the general public. you may have to send it back to hilti for service and reset. this is free if the machine is less than 2 years old.

The light remaining on means that the tool needs serviced. I would check the brushes first for wear and if worn excessively it needs to be sent for service ( brushes, o rings and lube) If not bad the switch could be bad and the service light needs to be reset. Let me know and I will try and help

    found your reply sorry for the delay new to system, but if still having trouble what you need to do is remove the handle assembly from the body of the tool it will unplug from the tool and then plug cord in to a live outlet and pull the trigger and hold while unplugging reassemble and the light should go out if any problems let me know and I will try and keep on top of it.

    I have the same issue, tried your fix but no luck, checked the brushes, one has a few chips out of it but does not look worn down...could these missing chips be my problem?

What does the p stand for on a hilti te-76 p atc


That means it has available Hilti's theft protections system. You can purchase a electronic key that when you swipe it over the tool it programs itself to that tool. After the tool is unplugged for 20 minutes after it is programmed it will not run again until you swipe the tool with the key.

How to reset Active Torque Control in the handle of Hilti model TE76P-ATC Rotary Hammer Drill


Active Torque Control (only TE 76-ATC / TE 76P-ATC)
The TE76-ATC / TE 76P-ATC is equipped with the Active
Torque Control system in addition to the mechanical
torque limiting clutch. This system offers additional protection
while drilling by rapid shutdown upon uncontrolled
rotation in the axis of the drill bit, e. g. when the
drill bit jams due to hitting rebar or when the insert tool
is tilted unintentionally.
When the ATC system has become activated, the tool
can be restarted by releasing the control switch and reengaging
it after the the motor has stopped rotating
("click"-sound signals readiness for use).
Always choose a working position in which the electric
tool is free to rotate in a counter-clockwise direction
(as seen by the operator). If this is not possible, the ATC
system cannot react.

Service light


You can reset the light. What you need to do it remove the handle assembly from body of tool. The contacts will unplug. Then plug the cord in and pull the trigger and sometimes the light will blink, while holding the trigger in the on position unplug the cord. reinstall the handle and the light should go out. Sometimes you have to pull the trigger while plugging cord in but this should work. and then while holding unplug cord.
