Do not put it in hammer mode and try to unscrew the chuck! This will break the housing internally. To remove the chuck you will have to put a chisel in the chuck. Lock that chisel in a big vice. You will then have to put a pipe wrench on the chuck to unscrew it. It is regular threads but there will be loctite on it. Once that is off your will have a spring and two roller bearings to remove before you can slide the bell off. You will then have 8 5MM screws to remove. This will remove the chuck. You will then have a snap ring to remove. After that you can remove the whole cylinder assy. More then likely your connecting rod is broken.

Manual for Hilti Te2 is here.
Per Page 11, "Pull the chuck release ring towards the front and remove
the chuck completely. When fitting the chuck, pull the
release ring towards the front and hold it in this position.
Push the chuck onto the guide tube as far as it will
go and release the ring. Rotate the chuck until it engages
and the ring snaps back into its original position |3|. The
TE-C interchangeable chuck or quick-release interchangeable
chuck may be tited to the TE 2-M with chuck

The TE-70 is permantly lubricated. You would only add lubricant if you took the tool apart. You can add a small amount of grease to the end of your bit occasionally before putting in the chuck. This keeps the chuck parts lubed.

Parts are no longer available for the TE12. Be carefull if you try to take it apart yourself. Some of the older models had a lead based grease in them
