Now, I can't find any place to replace or refill oil. Any one know about this air compressor?
It is a Magna Force. SCFM is between 4 to 7. Model number is 64A150-14. It looks just like the pic below. I searched the net but can't find manual.

The oil level and fill is in the lower picture and facing you, in the middle of the crankcase are two plugs. The lower is drain and the upper is fill. If it has a little dip stick, use that but if not, fill to the bottom of that particular plug. Don't overfill.
For the pressure, if you know your regulator is working and adjusted at the max but still not getting a full 100psi rating, pull the cover off of where the pressure SWITCH is. To find that, follow the electrical power lead from the motor and it may or may not be where the power on/off switch is, but its nearby. Once you find it, pull the cover and most likely it will have a screw with a nut for locking it down. If it has the locking nut, loosen it and crank the adjusting screw in a bit. DON't over adjust. Test run the compressor and you would be safe to set it for 125 psi. Secure that lock down nut (if it has it) and replace the cover.
