Open the chuck as wide as it goes. Look in, there should be a screw head
visible. The end of the motor shaft is tapped and threaded for this screw
and
it MAY be left-handed threads. Once this screw is removed you can unscrew
the
chuck from the drill. It should be right-hand thread.

You may also need to stick an allen key in the chuck (closed as if it were a
drill bit) and smack the allen key's "leg" with a quick blow of a hammer,
etc to get those threads to loosten up... Don't go wild though. If it
doesn't come loose, figure o0ut what your time is worth and consider
replacing the whole unit with something more appropriate for the work being
done.
