Just got my first keyless chuck drill and I am having

and started drilling on the hammer settings and after a few seconds
the drill fell out and rolled down the roof to the ground......this
can't be normal... am I doing something wrong?....instructions just
say tighten until clicks are heard......doesn't matter how tight I
make it the drill still falls out....any ideas ? ...
