Engine starting (with parking brake applied)
Safety and
emergency
equipmentBefore 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
engineSet 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 positionNorP(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
pressureVerify 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).
AcceleratorPress 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.
VoltmeterCheck the gauge (diesel engine) or indicator light
(gasoline engine) to verify the alternator is
charging.

Engine starting (with parking brake applied)
Steering linkage
free playInspect for excessive free play in the steering
linkages. The steering wheel should have less
than 2 inches (5 centimeters) of free play at its
rim.
Full power
hydraulic brake
inspectionPump the brake pedal several times with the
ignition in the off or run position. You can
momentarily hear the motor and pumps
replenishing the accumulators.
Parking brakeVerify the parking brake holds the vehicle by
gently trying to pull forward with the parking
brake applied.
Air brakesVerify operation using the following procedure.
Chock the wheels, if necessary. Push in the
parking brake and, on tractors, push in the
tractor parking brake knob:
1. Verify the air compressor or governor cutout
pressure is approximately 120 psi (827 kPa).
2. Turn off the engine, and then turn the key
back to the on position (without starting the
engine).
3. Without the brake pedal applied, note the air
pressure drop for one minute. It should be less
than 2 psi (14 kPa) for single vehicles and 3 psi
(21 kPa) for combination vehicles.
4. Press and hold the brake pedal with 90 psi
(621 kPa) or more. Make sure there is no more
than a 3–psi (21 kPa) per minute leak for single
vehicles and a 4–psi (28 kPa) per minute leak for
combination vehicles.
5. Pump the brake pedal to deplete the system of
air pressure. The warning light and tone should
turn on at 57 psi (393 kPa).
6. Pump the brake pedal and make sure the
parking brake and trailer parking brake knobs
pop out at 20 psi (138 kPa) or higher.
Automatic
transmission fluidVerify that the fluid level is in the proper
operating range. SeeTransmission fluid check
in theMaintenancechapter.
