air vent plug (Fa) with one turn.

Always drain the compressor oil at all drain points. Used oil left in the compressor can
contaminate the oil system and can shorten the lifetime of the new oil.
Never mix lubricants of different brands or types as they may not be compatible and the

stuck on the air receiver/oil tank.
