Parts in this zone
- 1
Ignition switch / key
What to check: Key to on (battery charge) for electrical checks; start engine for gauge and air build-up checks; engine off for the leak and warning-device tests.
- 2
Clutch pedal and gearshift (safe start)
What to check: Depress the clutch, place the gearshift in neutral (or park), start the engine with the parking brake set, then release the clutch slowly.
- 3
Seat belt
What to check: Securely mounted, adjusts, latches properly, not ripped or frayed.
- 4
Dashboard indicator lights
What to check: Show that the left turn, right turn, four-way flasher, high-beam, ABS (and DEF, if equipped) indicators light when the corresponding control is used; the ABS light comes on then goes off at start.
- 5
Oil pressure gauge
What to check: Gauge works and shows increasing or normal oil pressure after start (or the warning light goes off).
- 6
Coolant temperature gauge
What to check: Gauge works and temperature begins to climb to the normal operating range (or the temperature light is off).
- 7
Ammeter / voltmeter
What to check: Gauge shows the alternator is charging (or the warning light is off).
- 8
Air pressure gauges (primary/secondary)
What to check: Gauges are working; air builds to governor cut-out at approximately 120-140 psi (or manufacturer spec); the 2005-system NY text says 100-125 psi.
- 9
Windshield
What to check: Clean, no obstructions or illegal stickers (inspection sticker allowed), no cracks or damage to the glass.
- 10
Mirrors (adjusted from inside)
What to check: Mirrors clean and properly adjusted from the driver's seat; cameras/monitors (if equipped) clean and the display operable.
- 11
Wiper arms and blades
What to check: Arms and blades secure and not damaged; turn the wipers on to show they operate smoothly, then off.
- 12
Windshield washers
What to check: Activate the washers to show they spray and work correctly; washer fluid present.
- 13
Heater / defroster controls
What to check: Identify, describe and demonstrate that the heater and defroster work by operating the controls (fan and defrost setting).
- 14
Electric horn (steering wheel)
What to check: Press to show the electric horn works.
- 15
Air horn (lanyard/button)
What to check: Pull the lanyard or press the button to show the air horn works (check both horns if equipped).
- 16
Steering wheel (free play)
What to check: With the engine running (power steering), turn the wheel back and forth: play should not exceed 10 degrees (about 2 inches on a 20-inch wheel) before the front left wheel barely moves.
- 17
Parking brake control (yellow diamond knob)
What to check: Pull out to set the tractor spring brakes, push in to release; used in the parking brake check, the leak test and the pop-out test.
- 18
Trailer air supply / tractor protection control (red octagon knob)
What to check: Pull out to apply the trailer spring (parking) brakes, push in to charge the trailer; must pop out (close) between 20 and 45 psi at the same time as or before the yellow valve.
- 19
Trailer hand (trolley) valve
What to check: Applies trailer service brakes only; some schools use it for the trailer tug test, but the manual's trailer brake check uses the trailer parking brake (red valve).
- 20
Service brake pedal
What to check: Fully apply and hold for the one-minute applied leak test; pump (fan) to drop pressure for the warning and pop-out tests; apply at 5 mph for the service brake check.
- 21
Low air pressure warning (buzzer, light, wig-wag flag)
What to check: Must activate before air pressure drops below 55 psi (modernized) or 60 psi (2005 system); say the psi at which it came on.
