Hitachi EC12 Portable Electric 2HP Oil Lubricated Air Compressor Parts

Replace the entire regulator. You buy parts but you will be money ahead to buy a new one.

The EC12 holds 8 ounces
I recommend synthetic

SAE 5W50 and if available use full synthetic.

This link will take you to the EC12 owners manual if you would like.

Number 63 but go to this site for manual.

You have to manually adjust the pressure regulator. Make sure drain is completely closed. The one thats on the bottom of the tanks

can get manual from where you purchased the unit if purchased new http://www.toolpartsdirect.com/cgi-bin/schematic.cgi/hitachi/EC12

here you will find a parts manual

There should be a pressure switch adjustment under the cover of the switch remove the cover and reset.

There is a seal between the compressor and the motor that in failed condition will leak oil into motor windings causing burnt oil smell. Some hitachi compressors suffered from failed valves or head gasket causing extra heat but not oil smell. These compressors also have a thermobreaker built into the windings that when failed will prevent motor from starting or would start and run for only a few moments then open. This part is not replaceable. enjoy
