STARTING PROCEDURES
Operating precautions
•Always shift to a lower gear at high altitudes to prevent engine
smoking.
•Avoid extended and unnecessary idling.
Do not operate a diesel engine where the vapors can be
combustible. These vapors can be sucked through the air intake
system and cause engine acceleration and overspeeding, which may
result in bodily injury and extensive property damage. The equipment
owner and operator are responsible for safe operation in a hostile
environment.
STARTING THE ENGINE
1. Ensure headlamps and all accessories are turned off and the parking
brake is applied.
2.Automatic transmissions,ensure gearshift is in N (Neutral).
3.Manual transmissions,ensure
gearshift is in neutral position and
clutch pedal depressed.
If your vehicle is equipped with an
air intake heater, the heater will
activate in cooler weather. If the
Wait to Start light illuminates,do
notcrank the engine until the light
goes off.

If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could result in damage
and/or personal injury.
4. Do not depress the accelerator during starting the engine.
5. Start the engine.
If the engine does not start after 30 seconds of cranking, allow two
minutes for the starter to cool before trying again. Excessive cranking
may damage the starter.
After the engine starts:
•On some engines, the Wait to
Start light should illuminate after
the engine starts. Allow the
engine to idle about three
minutes or until the engine
coolant temperature gauge begins
to rise. Maintain idle speed until
the Wait to Start light cycles off
to indicate the air intake heater
has shut off (approximately six minutes). Operating the engine at
higher speeds will reduce the effectiveness of the air inlet heater.
•Do not increase engine speed
until the oil pressure gauge
indicates normal pressure.
•Ensure engine oil pressure is
indicated on the gauge within 15
seconds after starting.
•Idle the engine for three to five
minutes before operating with a
full load.
•Try to limit engine idle to 10
minutes. Excessive idling reduces fuel economy.
•When starting a cold engine, increase the engine speed (RPM) slowly
to make sure adequate lubrication is available to the bearings.

RESTARTING AFTER RUNNING OUT OF FUEL
The fuel system may need to be purged of air, refer toRunning out of
fuelin theMaintenance and carechapter.
OPERATING THE ENGINE
Do not operate the engine at full throttle below peak torque engine
speed (RPM) for more than one minute at a time (peak torque RPM
varies from 1200-1500 RPM depending on engine rated speed).
Monitor the oil pressure and coolant
temperature gauges frequently.
If the gauges indicate any reading is
not in the normal operating range,
stop your vehicle as soon as
possible, shut the engine off and
check the appropriate fluid level. If
an overheating condition starts to
occur, release the throttle pressure
or shift the transmission into a
lower gear, or both, until the
temperature returns to normal operating range.
Continuous operation with low coolant
temperature, below 60°C (140°F) or
high coolant temperature 100°C
(212°F) can damage the engine.
Most failures give some kind of early
warning. Look and listen for changes
in performance, sound or engine
appearance that can indicate service
or engine repair is needed. Some
changes to look and/or listen for:
•Engine misfires
•Loss of power
•Sudden changes in engine operating temperature or oil pressure
•Excessive smoke
•Fuel, oil or coolant leaks
•Vibration
•Increased oil or fuel consumption

EXHAUST FUMES
Never idle the engine in closed areas. Never sit in a parked or
stopped vehicle for any amount of time with engine running.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
In order to guard against fumes entering your vehicle, the exhaust
system and body ventilation system should be checked by a qualified
technician:
•Each time the vehicle is raised for service.
•Whenever a change in exhaust system noise is noted.
•Whenever the vehicle has been damaged by impact from another
vehicle, object or road obstruction.
In order to afford proper operation, all air inlet vents should be kept
clear of snow, leaves and other debris.
If you run the engine while stopped (idled) in an unconfined area, open
the windows at least 2.5 cm (one inch) and adjust the heating or air
conditioning to draw outside air into the vehicle as follows:
•If your vehicle has outside air control vents, open them fully.
•Set fan speed on high with function control to any position except
OFF or MAX A/C and the temperature control on any desired position.
•Adjust air control system to force outside air into the vehicle.
BACKING UP
To avoid the possibility of personal injury while backing the
vehicle, always be sure your vehicle’s path is clear.
Before backing your vehicle, be sure you can do so safely. If anything
behind the cab limits your view, do not rely on mirrors alone to assure
that your intended path is clear. If other persons are in the vicinity, have
someone standing well behind the vehicle and outside your intended
path - visible through an exterior mirror - guide you as you back up.

not affect braking effectiveness. The brakes should be checked only if
squeal occurs continuously with every application.
If brakes do not grip well
•If you have been driving through deep water, gently apply the brakes
several times while the vehicle is moving slowly.
•Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high speed stops.
•Check brake adjustment.
•Check brake linings for excessive wear.
•Check system air pressure.
Air brakes
After starting the engine, give the air compressor time to build up the air
pressure to 414 kPa (60 psi) before moving the vehicle.
Do not drive or continue to drive if the low air pressure buzzer
is sounding or the brake warning light is lit. These warnings
indicate that air pressure is not to normal operating level. Continued
use of the vehicle could result in loss of braking ability.
Avoid repeated light application of the brake pedal. This will
deplete air pressure faster and could result in loss of braking
capability.
Periodically check the air pressure
gauge while driving. Pressure should
range between approximately 703 to
930 kPa (105-135 psi). The air
compressor governor cut-in and
cut-out pressure settings are preset
at the factory and are not
adjustable.

When air pressure is insufficient
(below 534 kPa [60 psi]), a warning
light illuminates and a buzzer
sounds when the ignition is in the
ON position.
This condition may be caused by excessive brake applications depleting
the system air pressure. If this condition occurs, stop driving the vehicle
until the compressor has fully recharged the air system. Do not move the
vehicle in this condition because the brake system may be inoperative.
Select a gear ratio to help slow your vehicle before descending grades.
Supplement with brakes as required to safely slow the vehicle and avoid
overspeeding the engine.
Air chamber stroke indication
All Ford air chamber push rods have orange stroke indicator stripes that
alert the operator when the braking system requires adjustment or
repair. The orange stripe is painted on the air chamber push rod at the
slack adjuster readjustment stroke dimension.
Air brake inspection and adjustment should be performed by a qualified
service technician in accordance with the instructions in the Ford Truck
Service Manual.
Cam brakes—automatic slack adjusters
Standard air brakes (cam) are
equipped with automatic brake
adjusters. Automatic adjustment
occurs during forward and reverse
brake applications. Inspect brakes
for proper adjustment at the
intervals listed in the vehicle Service
Maintenance Guide.

DRIVING WITH A MANUAL TRANSMISSION, IF EQUIPPED
Continued use of a damaged or worn clutch, prolonged clutch
slippage or downshifting at excessive speeds can result in a
failure of the engine, transmission or clutch components.
To avoid premature clutch wear and failure, do not drive with
your foot resting on the clutch pedal or use it to hold the vehicle
at a standstill on an upgrade as when waiting for a traffic light.
Manual transmission shift patterns
are displayed on the shift lever
knob.
Study this information carefully before you drive the vehicle even though
you may be familiar with similar units. Do not attempt to drive the
vehicle without knowing the exact shift pattern of the transmission.
Consult your authorized dealer if any questions exist as to the shifting
instructions posted in your vehicle.
Do not coast the vehicle with the clutch pedal depressed or with
the transmission in neutral. This practice could result in loss of
vehicle control.
