1. (Start the tractor, push red and yellow buttons in, buckle up the safety belt)

2. (Paperwork) company CVOR, ownership, insurance certificate, safety inspection certificate matching this sticker, log book and inspection report filled by My instructor

4. (identify gauges) secondary air tank, primary air tank, air brake application, water temperature, oil pressure, pyrometer, tachometer, speedometer, battery voltage, do you want me to identify the others?

5. Next I will listen for any air leaks. (make sure the red and yellow buttons in, shut down the engine)I will be applying a steady brake to 30 psi, the first time I am not allowed to lose more than 8 psi, afterthat, I am not allowed to lose any more than 4 psi every minute.(hold the brake padel to 30 seconds)since My gauges keep stable, I am not exceeding that limit. And I don’t have any audible air leaks.

6. I will deplete My air system. (start the engine) Again, each time I apply air brake to 30 psi, I am not allowed to lose more than 8 psi each time. (fan the brake)at or before 55 psi, My low air pressure warning lights and buzzer will active. (when the devices active)now at 55 psi, the low air pressure active, they are working properly. (pull out the red button)at or before 40 psi, my trailer spring brake will apply,(pull out the yellow button)at or before 20 psi, My tractor spring brake will apply.

7. Next I will rebuild My air system.(put on cruise control to 900 RPM)at 900 RPM, it will take no more than 2 minutes to go from 85 psi to 100 psi, it will tell me my air compressor and govenor working properly. Now that it take me 40 seconds to go from 85 psi to 100 psi, My air compressor and govenor working properly.

8. Next I will perform brake checks:  1)trailer spring brake 2)tractor spring brake 3)trailer service brake 4)tractor service brake
