Hilti TE 17. Hammer doesnt work. Rotary does.

According to the operating instructions for the Hilti TE 6-A22, if the rotary hammer is running but there is no hammering action, it could be because the rotary hammer is too cold. To fix this, bring the tip of the drill bit into contact with the working surface, switch the rotary hammer on and allow it to run. If necessary, repeat the procedure until the hammering mechanism begins to operate. Also, ensure that the function selector switch is set to "Drilling without hammering" .

If this doesn't work, you may need to take your tool to a professional repair service. You can find a list of authorized Hilti service centers on their website.

the header list 2 different drills, if yur chuck has a colllar with a quick release, I would suggest thoroughly cleaning and then using a lubricant, usually there are steel balls that lock into detents in the spindle and they might be stuck the collar should move freely.

It depends on where the leak is. if you email me I can send you an exploded diagram of tis machine. This will give you an idea of how to take it apart.

Check the motor if the motor has power and then the gears are not working. If the motor doesnt have any power then you need to check for power. To get at the gears you are going to need to remove the chuck
