None of the above

When the psi drop below 20 psi

It doesn't

When it separates from the circuit it supplies

20 / 30

What causes hose bulges within the air lines?

Internal structure failure or excessive chaffing

Too much air being pushed through the lines

Debris in the air lines

21 / 30

To check the air compressor, run the engine at 1200 rpm and stop the timing when the air pressure is at what rpm?

120 psi

140 psi

It doesn't matter as long as it's been running for six minutes

90 psi

22 / 30

To check the governor, the cut out should be at what rpm?

120-135 psi

70-85 psi

150-170 psi

80-90 psi

23 / 30

Air system failures are sometimes dealt with by blocking off the air lines that supply the failed component. Is this acceptable?

Only if directed by your employer

Never

Yes, until you get back to the yard

If driving at low speeds

24 / 30

What would you have to do to confirm that the brake chamber is securely installed?
