That is a service light and means there is some type of failure. If this tool is under warranty I would call 1-800-879-8000 and see about getting repaired. If not go to Hilti.com and download a breakdown for this tool. You might want to check the brushes first for wear because they have a sensor that triggered the light.

Hi, The TE50 is a fairly new SDS Max machine released from Hilti in the last 24 - 30 months. The red light is a service indicator light which comes on when a services is due. After 10 hours of working time after the light comes on, the machine automatically turns off to protect the motor and gears and usually brushes need replacing. The warranty on the machine is 2 years no cost, so you should not be in for a supprise bill should the machine be under this time. Hope this helps.

    brought it back from dead.
    same problem here. Does the light goes of if I change the brushes? or I still need to take it to the dealer?
    guess for this model they use the newer diagnostic tool for it so I wont be able to reset it by doing the handle trick?

    thanks a lot

Trouble light comes on, can barely read the instruction around it(faded over time)It says to push a red button but not sure where the button is. Help!!

When trouble light comes on, it indicates that the hi-limit is tripped (this happens when oil temperature exceeds 450 Fahrenheit). The red button is located at the upper back panel of the unit, give it a push to reset but if nothing happens after resetting the button, the hi-limit needs to be replaced. Also try to check if the thermostat is working, stuck thermostat's mechanical contact will cause the hi-limit to trip.

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
