Umarex Help

[ChrisS]

So I bought a used Umarex Hammer, good condition but it has a small leak, like 4 days to drain the tank. I've been into a lot of different airguns but...are there any pitfalls to the Hammer that I should know about? I have gone thru the internet and can find no drawings of the gun, anyone have a set?

Thanks
Chris

Amazing, not even a parts diagram in the owners manual.
