I am so sorry you didn't receive any paperwork with your air compressor! If you would please click on this link for your FNB06A6U4JXPC, then click on the Specs tab and look to the right you will see PDF download links for the Owner's Manual, the i-Command Touch Manual, the Extended Warranty, and the Spec Sheet for the product line.
I'll also email the documents to you through your account. If you have specific questions that aren't covered by the manuals please feel free to call FS-Curtis tech support at 800-388-8370. If you do need to call them please also have the serial number of your compressor handy in case they ask for it.
We appreciate your business, and apologize for any inconvenience.
