I am visiting as I type to a gentleman ( on Skype ) who is an employee of 
Home Depot
here in Missouri and I won't mention which store but he is an amateur. He is 
the  ( Tim
the tool ) rental man here. He recommends the Hilti 505 and says that you 
didn't get a
hammer drill with your description of the gearshift on the side. He also, as 
the folks on
this list have said, suggested that there will be no chuck, only a socket 
that will set over
the end of your rod. Hope this helps.

Placing a 5/8 ground rod in a 5/8 chuck will work till you hit a hard rock 
of dense clay and then the mushrooming will get ya. That's a been there done 
that tip.
  I have also seen on some hammer drill models that in the hammer mode that 
the shape of the rod compared to the bits made for the hammer does not allow 
the rod to contact the hammer piston follower and enable the hammer only 
mode. The follower has to be pushed up about 3/16 inch to contact the hammer 
through the cushion between them. That's why the rod adapters are mandatory 
on some models.
  The clay up here in the north west is only about a 100 years short of 
being rock. It chips just like it and is impermeable to water. A 16 lb 
sledge just mushrooms the rod after a foot or so but the larger hammers will 
do the job albeit slowly though.
  I would complain to where you rented it as they instructed you as to its 
usability and it was unsuitable. A rent reduction at least, or another 4 
hours on them with one that works.

  Good luck,
