Vehicle Inspection Guide 15 Engine starting (with parking brake applied) Safety and emergency equipment Before entering the cab, verify that the vehicle is equipped with spare electrical fuses (if used), three red reflective triangles, a properly charged and rated fire extinguisher and wheel chocks. Walk around the vehicle and verify all steps and grab handles, inside and out (as well as behind), are tight and clean. Use extreme caution and a three-point stance at all times. Inspect door latches for proper closing, latching and locking. Starting the engine Set the parking brake. If starting a vehicle with a manual transmission, press the clutch and verify the transmission is in neutral.
If starting a vehicle with an automatic transmission, make sure the gearshift lever is in position N or P (if equipped with a park position). Diesel engine: Turn the key to the on position. Turn the key to start when the wait to start indicator light in the instrument cluster turns off. Gasoline engine: Turn the key to start, and then release it as soon as the engine starts. Engine oil pressure Verify pressure builds to normal operating range. Low air pressure warning tone (if equipped with an air compressor) A tone indicating low air pressure should sound immediately after the engine starts but before the compressor has built-up pressure.
The tone should stop when the air pressure reaches 70 psi (483 kPa) (or more). Let the air pressure build to governed cutout pressure, which should occur between 115–130 psi (793–896 kPa). Accelerator Press the accelerator and verify that it operates smoothly, without any binding or irregular feel. Release the pedal and verify the engine returns to idle speed immediately. Voltmeter Check the gauge (diesel engine) or indicator light (gasoline engine) to verify the alternator is charging. 2015 F-650/750 (f67) Owners Guide gf (ownloose) , 1st Printing, December 2013 Canadian_French (fr_can)
