How do you drive an F750?

Answer 1

For the most part, it's just like any other vehicle you've driven, with the exception of having air brakes. If it's a manual, it'll either be an Eaton or Spicer six or seven-speed transmission, which is synchronized, and shifts the same as a manual transmission in a passenger car (although the shift pattern itself is different, with reverse in the position normally used by first gear in a passenger car). The automatic will be an Allison... you just push the "D" button, use the arrow buttons if you want to restrict your gear, etc. The yellow knob is the brake control valve for the air brakes.. the air pressure in the primary air system needs to be at least 60 psi in order to have substantial hold off pressure for the spring brakes before you can release the brakes.
