dont have a manual! and i just took apart all but the bolt assembly sprayed it all down with gunscrubber and wiped it then lightly oiled it and reassembled it. while back i had to get a new scope as the one on it went bad. took it out and shot a couple boxes thought it figured out scope was junk, so i got a replacement, and sighted in best i could, but no good groups.it just aint been the same since then!!! maybe its shot out and time to buy a new!!
