the book should tell you.
what are you planning on running with that. It looks nice but it wont run most air tools.. would be great for tires.. and intermittant use such as nailers etc.
the below is from a review on amazon.com it kinda answers some of that:
I just received the compressor and it's the first one that I've owned. The shroud was cracked upon receipt, but I don't think it's worth the trouble to have that piece replaced.
Now that I've gotten everything figured out, I think it'll work fine, but the manual is a complete disaster. Some important setup instructions are completely omitted and others are so obtuse as to be worthless. If you don't know your way around compressors, the following steps that I took may prove useful:
1. Remove the plastic plug on the back of the compressor and pour in the included oil until the level is about half way up the little transparent indicator window.
2. Replace the disposable oil plug with the long black plastic one that they include (not in the instructions -- the piece is item number 36 on the parts diagram)
3. Remove the other disposable plastic plug from the side of the compressor (high up and toward the back of the shroud. This is where you need to install the air filter (also not in the instructions.) The air filter assembly is item number 35 on the parts diagram -- it's the other spare part included that's chrome and about the size of a hockey puck with a wing nut holding it together.
4. You'll screw in the air filter assembly where you removed that plastic plug, but I'd suggest that you use some teflon tape on the threads to make a good seal.
5. The instructions mention that you're to open the air receiver's drain valve for initial start up. Nowhere in any diagram is any part labeled as such, but I'm pretty sure it's item number 47, a valve on the side of the compressor very near the bottom.
