You'll have to call Hilti for that. They're very protective of their material. But I think they'll still fax you a schematic.

If this is a Hilti demolition hammer! You can contact Hilti USA Direct at (800) 879-8000

If you have the old type TE905, which is the one with the square type handle at the back, the service light will come on for 2 reasons. Either there is a tight bearing which will increase the amount of current used to work the machine. Or more common the carbon brushes need replacing. To reset the light, simply cure the problem.

If you have the newer type TE905 with the large “D” Type handle at the back. It gets a bit more complicated. The service light will come on for the same reasons as mentioned above, but it will also come on after 200 hours of use. It will continue to work for another 50 hours with the light on, then it will shut down completely. This is to ensure that it gets regular service. Once serviced or repaired, it will require resetting. To do this you with need a Hilti optical interface, a PC, and Hilti ODA Software. This is not available to the general public. If your Hilti is less Than 2 years old, call Hilti. They will pick it up, repair it, and send it back to you in 3 working days FREE OF CHARGE. If it is older than 2 years there will be a charge for the repairs.
I hope this helped you. Please leave feedback

Did you contact the place you purchased it from? If you still have the paperwork that came with it might have the replacement part #s in one of the flyers. Google the make and model.

Some of them typically to start up slow. Less wear on the motor. Also make sure you're not using too much drop cord. No more than 100 ft 12/3. May be the brushes if you've had it for awhile. Please rate me
