They all seem to have the chuck inside . . . you'll need to dissaemble from the looks of it.

There are 3 models with owner's manuals for each of them on HFT's site, there is an exploded view in the manual. The link to the manual is on the bottom of the page.

Usually, with smaller chucks like these, there is a screw inside the chuck (open the jaw all the way and look inside, one of the LOYL's cosmetic mirrors may be handy here) that needs to come off and the chuck threads onto the shaft. The screw is like a normal 'righty-tighty/lefty-loosey' but the chuck will reverse thread onto the shaft . . . or exactly the opposite with a lefthand thread on the screw and a normall thread chuck.

If there is no screw inside, there may be a small set screw on the outside of the chuck to set the chuck into a keyway on the shaft, but FWIW, I've never seen one like that.

Lastly, it also may be a pressure fit using a Jacob's Taper . . . but that is not likely for a small chuck like this. If it is, you just need to pry it off by moving the lever down, putting in a block of wood around the quill right above the chuck and forcing the lever back up, it should pop right off if it's a JT. Try this LAST, you'll likely cause damage if it's not a JT.
