Hi there Karl.
I've got a new compressor from the store, they where really nice, no problem at all, it seems like they had more in stock after all....
We opened it up in the store and the hose that went from the compressor to the little airtank had completly exploded. This time i talked to a older man who seemed to know a little, and ten minutes later i walked out of the store with a brand new compressor. With documentation
So there's no need for you to scan them anymore.
And you are right, i mean the relief valve.
I use the valve so that the engine doesn't have to work more than neccesary. Not after my disaster yesterday anyway...
I would like to thank you for your help and moral support, it really means alot when someone take the time to help a noob out.
So, thanks alot ,and i hope you'll have a nice summer
