pull back on the collar of the chuck and slide it on and then release the collar and turn till it locks onto the spindle.

I have just dismantled my own TE 905 to see why it was dropping the chisels and have found the following:-
1. The chisel is worn and has almost become too small for the chuck. (mesure the thickness of the chisel at both ends of the hexagonal shaft and see the difference)
2. The chuck is worn and will probably need to be replaced.
I phoned Hilti today and was quoted £100 for ONE PART OF THE CHUCK!!!
a. The chuck as a whole can easily be removed by undoing the four torx screws that hold the chuck on to the main body.
b. The chuck can be dismantled by removing the retaining ring that holds the metal outer case in place at the front of the chuck. This is very fiddly and requires some engineering skill, the use of pointed instruments could easily result in injury.
The third fix is the one I am going to use to 'patch up' my old breaker. This involves welding some small amounts of dissimilar weld onto the points of the hexagonal section at the rear of the chisel then grinding them to near enough the original size of the un-damaged section of the chisel.
This will very crudely stop the chisel from passing the ball bearings inside the chuck. PLEASE NOTE THAT ANY HEAT APPLIED TO THE CHISEL WILL CAUSE STRESS AND POSSIBLE FAILURE OF THE CHISEL. ANY MODIFICATIONS OF THIS NATURE COULD RESULT IN INJURY TO PERSONS WORKING AROUND YOU AND ARE NOT RECOMMENDED IF YOU ARE WORKING AT HEIGHT OR WITH PEOPLE BELOW YOU. This is a fix that should only be attempted by competent engineers for use on a DIY or small job basis. Hope this helps.

SOURCE: chuck fell off!
You did not state which model you had but normally on Hilti drills with a removable chuck you just put the nose of the chuck in the palm of your hand. Take your fingers and pull back the sleeve. Slide it back on the guide tube and then turn it until it catches. If that does not work then something is wrong with your chuck.

SOURCE: Hilti UH650, replacing the chuck
There are a couple of differant versions of the 650. Open up your chuck as wide as you can. Like you were putting a big bit in it. Look inside to see if you see a screw head. It might be slotted or torx. It will be left handed threads which means you will turn clockwise to remove. Once that screw is out you lock the front of the chuck in a vise and right behind the chuck will be a place to put a thin wrench. Turn the wrench in a counter clockwise motion away from the chuck.
