Why is there no hammering action on my Hilti Drill?
If your Hilti Drill is not hammering, it could be because the power tool is too cold. Try bringing the tip of the accessory tool into contact with the working surface, switch the power tool on, and allow it to run. Repeat if necessary, until the hammering mechanism begins to operate.
What does it mean when the service indicator lights red on my Hilti Drill?
If the service indicator light on your Hilti Drill is red, the carbon brushes are worn. Have them checked and replaced by a trained electrical specialist.
How to fix a Hilti Drill bit that does not rotate?
If your Hilti Drill bit does not rotate, the function selector switch might not be correctly engaged. Ensure that the motor is at a standstill and set the function selector switch to the “Hammer drilling” position.
Why does my Hilti Drill not achieve full power?
If your Hilti Drill (Combihammer) isn't achieving full power, first ensure the control switch is fully pressed. If that doesn't work, the extension cord may be too long or the conductor cross-section might be inadequate; use an extension cord of an approved length and adequate conductor cross-section. Also, the voltage provided by the electric supply could be too low, so connect the power tool to a different power source. Finally, if you are using TE 70-ATC/AVR or TE 80-ATC/AVR model, check if the half-power button is engaged and press it to disengage.
What to do if my Hilti Drill does not start?
If your Hilti Drill (Combihammer) doesn't start, there might be an interruption in the electric supply. Try plugging in another electric tool to check if the outlet works. Another reason could be that the generator is in sleep mode, in this case apply a load to the generator by connecting a second power consumer, then switch the tool off and on again. Also, the electronic restart interlock may be activated after a power interruption, so switch the power tool off and then on again. Finally, the carbon brushes may be worn, have them checked and replaced by a trained electrical specialist if needed.
How to release a stuck drill bit from my Hilti Power Tool?
If you can't release the drill bit from your Hilti Power Tool, the chuck might not be pulled back fully. Pull the chuck back as far as it will go and remove the accessory tool. Also, the side handle might not be fitted correctly. Disengage the side handle and refit it correctly so that the clamping band and side handle engage in the recess.
Why doesn't my Hilti TE 70-AVR drill bit rotate?

What to do if Hilti Drill bit is not released?
