In an air brake system, the air compressor governor controls when the air compressor pumps air into the air storage tanks.

2 . The air entering air storage tanks may contain:

Water and compressor oil.

Frost.

Gravel.

Antifreeze.

The air that enters air storage tanks in an air brake system usually contains a certain amount of water and compressor oil. Because accumulations of these materials can damage the braking system, tanks are equipped with drains to allow their removal.

Let the vehicle warm up before driving to ensure that the fuel reaches the engine.

Let the air compressor build up a minimum of 100 psi pressure in the primary and secondary systems before driving.

Begin driving just after the vehicle starts.
