| When operating a fire department aerial apparatus on a downgrade, the driver/operator should do what? | Select a lower gear before ascending and remain in gear at all times |
| Where is the hydraulic oil pressure gauge located? | Operators control panel |
| Before the stabilizers on an aerial apparatus can be utilized, power must be transferred from the engine to the hydraulic system, this is done by engaging the vehicle’s | PTO |
