Pneumatic tool question

[Itsahobby]

I bought a set of pneumatic tools off ebay. They
didn't come with instructions. I was wondering if
someone could give me a ballpark on what presure
I should run.
1/2 impact
3/8 rachet
mini grinder
air hammer
Thanks for any input.

My shop air usually runs around 125. The navy makes you regulate down to 75, but that sucks ass.
Most tools run best over 100, less than 140.

Shop pressure is 170-190 psi. No regulators. My 1/2 inch air impact will bust any import crank bolt on the planet! The only tool I regulate the pressure down on is the die grinder. I have not experienced any damage to my air tools and I use them every day. They are all Snap on, Mac, etc.

Don't forget to oil them once in a while when used heavily, Marvel Mystery oil works good or real air tool oil or even ATF :)
