PM Inspection - Refueler
Hull and machinery inspections, along with routine maintenance tasks (e.g. oil changes and alignment checks) help to maximise a vessel's lifespan and performance by avoiding unexpected breakdowns, minimizing the chance of malfunctions, and reducing the chance of malfunctions to name a few.

Engine on / Brakes on – check gauges to make sure governor cuts compressor off at 120 psi. Pump brakes until pressure drops below 100 psi to make sure governor cuts compressor on. Record cut in and cut out PSI.
Engine off / Brakes off – do not touch brakes – watch gauges to make sure pressure does not drop more than 3 psi in one minute.
Press and hold brake pedal – watch gauges to make sure pressure does not drop more than 4 psi in one minute
Turn- key on / Engine off / Brakes off – pump brake until pressure drops to 60 psi – warning buzzer should sound at or before 60 psi.
Continue pumping brakes until reaching 20 to 40 psi – Service (yellow) brake valves should pop out turning brakes on.
Rebuild air pressure in tank – hold accelerator at 1500 RPM. Watch air gauges and notice that pressure rate of build between 85 psi and 100 psi should not take more than 45 seconds. For 10K trucks air pressure will build slower as there are more tanks.
Perform tug tests. Tug against Parking Brake, under light throttle the parking brakes should hold the truck.
If there is a problem discovered while testing the Air Brakes, do not drive the vehicle. It is your responsibility to make sure it is repaired or create a work order and remove the truck from service.
