How to check for parking brake
Pull up on knob
Check insurance/reg
Above windshield/drivers seat
Check seatbelt
Close door
Toggle Door switch
Start engine/ master control switch
Build Psi
Allow psi to build to manufacturers specification which is 120 psi
If I were to toggle the idle switch, i must inform examiner “I am turning on the fast idle because the bus is equipped with a cut off switch at approximately 3 minutes.”
it will make it faster to build but I must remember to turn idle switch off when air gauge reaches 120 psi.
