Hatsan Hercules 25 Cal

[kxlexus]

Hi,
I am new to the forum and to Airguns. Although I am big into precision rifles. 
I found a bargain on a new Hatsan Hercules 25 caliber and jumped on it. I am finding very little information about this air rifle. About the only comments I see are complaints about how heavy it is. This doesn’t bother me at all. 
Where can I find a parts breakdown? It came with spare orings but I have no idea where they go. Can a regulator be added? Is it needed? How is the power adjusted?
Any tips would be greatly appreciated. 

Thanks,
Steve

Thanks for the quick replies. I like to learn how things work and work on things myself. I am looking more for information and videos about maintenance, repair and tuning on this particular air rifle vs sending it off. Really not finding anything on YouTube or through Google searches.

It's hard to get to the hammer spring on Hercules. The easiest way to regulate the spreed is by using heavier pellets. The tanks are the standard M18x1.5 threads so the Altaros regulator for an Air force gun will fit it. But the plenum is small so it will bring the power way down. The valve on the Hercules are pretty decent so it should have a good sxtreme spread. Hatsan uses the same springs in all the Hercules so any caliber under 30 cal will shoot very hot. My 30 cal shoots the 44 grain JSBs over 1000 fps but they are very accurate even at long distances.

Thanks for the replies. Hatsan USA didn't put much effort into the exploded view of the rifles. It gives part numbers but no descriptions.
