Muffler Bearing

I just took an Atlas Copco hammer class and found out some stuff I had never heard before, maybe this is common knowledge, but not to me.
1. If a hammer is greased improperly and grease gets between the piston and the tool, the impact can actually inject the grease into the metal!
2. If a standard hammer is used in water, the piston can act as a pump and draw water past seals and into the machines hydraulic system!
3. Without proper grease, the tool is passing by the bushing so fast that that it is spot welding! I guess technically this is what all metal transfer is, I just hadn't thought of it that way.
4. Lastly he just gave a really good explanation of why hammers should be stored vertically. If you leave them on their sides all the seals have to support heavy internal pieces like the piston. O-rings and backing rings aren't meant to be load bearing.
Any way it was a really helpful class, I wish I had taken it before I built 5 or 6 hammers
