Definitely clean it before you shoot it, then take it to the range and shoot it.
I believe Model 70's are made, or least assembled, assembled in Portugal now.
Sometimes, even the best guns leave the factory with defects.
(I bought a brand new Colt Python in 1990 that would not allow me to load cartridges into the cylinder chambers - I bought the gun as a Christmas present and didn't have time to send it back. I had to pay a local gunsmith to make it work. You would have thought the LGS (most "famous" gun store in Athens, GA, BTW) would have offered to assist, but they lived down to my expectations, like they always do.
My son recently purchased a brand new Tikka and had a gunsmith do work on it (including cutting and threading the barrel) prior to him shooting it.
He was absolutely meticulous in mounting a well respected scope.
We took it to the range and was very disappointed with the accuracy.
Since the rifle was "customized" prior to the first shot, I doubt that Tikka would honor their sub-MOA guarantee, and you couldn't blame them...
