Anyone with this compressor out there willing to help?

I just purchased the Makita MAC700 kit – the compressor and AF505 Brad Nailer.

I am trying to get going with this and I am beyond baffled. Some background – this is my first ever compressor and nail gun – I have never used either before.

From the docs:

“Serious damage will result from even limited operation unless filled with oil and broken correctly. Make sure to closely
follow initial start-up procedures. Compressor oil is provided; on level surface, please fill the crankcase to proper level
indicated on the sight glass.”

I added the oil – “oil at the dot when off – right oil level”.

Air Filter Assembly – I took out the clear plastic plug from the side of the cylinder head and screwed in the air filter assembly. I screwed it in as far as it will go.

Out of the box, the regulator was turned all the way in – clockwise (+) – up against the red “stopper”.

Initial Start Up Procedure:

1.Open the air receiver’s drain valve.
2.Plug power supply cord into correct power source.
3.Run the compressor for a minimum of twenty (20)
minutes in the no-load condition to lubricate the
bearings and pistons, and to seat the piston rings.
4.Close air receiver drain valve.

Is the air receiver’s drain valve the “drain cock” on the air tank? What is the no-load condition?
