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

Excessive full throttle operation below peak torque RPM will shorten
engine life to overhaul and can cause serious engine damage. Operation
of the engine below peak torque RPM can occur during gear shifting due
to difference of gear ratios.
COLD WEATHER STARTING
Perform the following to assure efficient starting in cold weather:
•Use the proper grade oil for your climate. Refer to your engine
operator’s manual for proper grade oil.
•Test the battery more frequently to assure ample power for starting.
•All electrical connections should be tight and in good condition to
prevent losses through loose or corroded connections.
USING THE ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant, which improves
starting, warms up the engine faster and allows the heater-defroster
system to respond quickly. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach -23°C
(-10°F) or below.
For best results, plug the heater in at least three hours before starting the
vehicle. Using the heater for longer than three hours will not harm the
engine, so the heater can be plugged in the night before starting the vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
ENGINE SHUTDOWN SYSTEM (IF EQUIPPED)
This system is designed to help prevent engine damage that could result
from operating the engine during a prolonged period of low engine oil
pressure, high engine coolant temperature or low coolant level. If any of
these conditions occur, a warning light will illuminate and a chime will
sound warning the operator that the engine will shutdown in 30 seconds.
This is to allow time for the operator to move the vehicle off the road. If
additional time is required, the engine can be restarted and run each
time for approximately 30 seconds.
Do not attempt to use this restarting feature to drive the vehicle, serious
engine damage could result.
Starting
80
Block the wheels to prevent the vehicle from moving.
Unexpected and possibly sudden vehicle movement may occur if
these precautions are not taken.
Impact wrenches should not be used as they may damage the piston and
prevent proper caging of the spring. Do not apply more than 68 Nm (50
lb-ft) torque to the release bolt nut.
1. Remove the stud tool and nut
from the carrying pocket on the
brake chamber assembly.
2. Remove the access plug from the
end of the spring chamber.
3. Insert the release stud through
the opening in the chamber and into
the spring pressure plate.
4. Turn the release stud one-quarter
turn to engage the stud tangs with
the slot in the pressure plate. Keep
the stud engaged and install the nut
on the release stud.
5. Tighten the nut until the spring is
fully caged and the brakes are
released. Do not loosen or remove
the release stud and nut unless the brake chamber is completely
assembled and is securely clamped.
6. When the air pressure is restored, unscrew and remove the release
stud and install in the carrying pocket. Install the access plug.

When operating the PTO unit with the vehicle stationary, first set the
parking brake (chock the wheels if the vehicle is on a hill or other
unlevel surface).
DRIVING WITH AN AUTOMATIC TRANSMISSION, IF EQUIPPED
Allison automatic transmission
Do not allow your vehicle to coast in N (Neutral). Transmission
braking is not available in N (Neutral). Allowing the vehicle to
coast in N (Neutral) could result in loss of vehicle control and severe
transmission damage.
The Allison automatic transmissions are a torque converter type, full
power shifting and fully automatic. They also have the added flexibility
of manually selecting and holding in the lower drive ranges which permit
the drive selection of the most suitable gear range to match varying road
and load conditions. To prevent destructive overspeeding of the engine,
the hold feature is not infinite, resulting in upshifts from the hold range
to the next higher range at some speed above the no-load governed
speed of the engine.
Allison AT-545
These transmissions have no P (Park) position. Before leaving
the driver’s seat, always shift into N (Neutral) and set the
parking brake. Shut off the engine and remove your ignition key.
Always use wheel chocks for hilly or off-road parking. Unexpected and
possibly sudden vehicle movement may occur if these precautions are
not taken.
This transmission provides four forward speeds and one reverse range.
R (Reverse)
Use this position to back the vehicle. Completely stop the vehicle before
shifting from R (Reverse) to any forward gear (1, 2, 3 or D). The reverse
warning signal will sound when the selector is in R (Reverse). Reverse
has only one gear and provides the greatest gear reduction.
Driving
102
The PTO gear is in constant mesh with the drive gear in the torque
converter housing. A friction clutch or constant drive is used to transmit
power to the PTO.
Power take-off (PTO) operation on vehicles equipped with a
Caterpillar 3126E engine
If your vehicle is equipped with a Caterpillar 3126E engine, the PTO will
only operate if the vehicle is in Neutral. This feature can be overriden by
a special service tool; see your dealer or service representative for more
information.
MAXIMUM VEHICLE LOADING
Every vehicle manufactured by Ford
Motor Company is supplied with
information on the Vehicle Rating
Decal listing the maximum loading
for the vehicle (GVWR), and its axle
systems (GAWR) at the tire to
ground interface.
Under no circumstances should your vehicle be loaded in excess of the
GVWR or GAWR. It is the operator’s responsibility to assure that neither
the axle capacities, spring capacities, tire capacities nor the vehicle rated
GVWR is exceeded. For tire capacities, refer toSpecifications and
capacitieschapter.
Unloaded or lightly loaded vehicles
The braking system has been designed to safely stop your vehicle when
fully loaded to its GVWR.
When operating empty or lightly loaded, sudden or hard braking
may induce wheel lockup with loss of vehicle control and the
possibility of accident and serious injury, especially on wet or slippery
road surfaces.

SERVICING YOUR WHEELS AND TIRES
Wheel assembly
Your vehicle is fitted with hub
piloted wheels and two-element
swiveling lug nuts (20 & 22 mm).
Do not use taper type wheels or ball
seat wheel nuts.
•Do not paint the mating face of the hub/drum.
•Do not paint the two-element swiveling lug nuts or wheel stud.
•Do not allow an excessive thickness of paint to build between the disc
wheel mounting surfaces.
•Do not install disc wheels where the paint has not fully cured.
•At wheel changes, ensure mounting faces are clean and free of rust,
dirt and excess paint.
If fasteners are needed, use only Ford recommended replacement parts.
•To maintain the desired
torque/tension relation between
nut body and flange, it is
necessary to use clean engine oil
meeting Ford specification
WSS-M2C153-G between nut body and flange. Lubricate the nut body
and flange any time a wheel is removed.
The M20 & M22 wheel nuts are right-hand threads. Refer to the
following chart for approved wheel lug nut torque.
Wheel type Bolt size Wheel nut torque
10-hole disc
285.75 mm bolt circleM22 (22 by 1.5 mm) 610-677 Nm

The disc wheel nuts on your vehicle were tightened before delivery.
Recheck torque of nuts at 160 km (100 miles) and 800 km (500 miles) of
new vehicle operation or any time a wheel is removed. Reset to
recommended torque levels.
Maintenance and care
147
Tire inflation pressure must not exceed the recommendations of
the axle, tire and/or wheel rim manufacturer for the specific
load, speed and application. The inflation pressures on the tire sidewall
do not take the wheel rim capabilities into consideration.
Never use a rim of different manufacture or any different size or
type than original rims.
Try to replace tires in pairs on the same axle shaft. Tires larger or
smaller than originally installed may affect the accuracy of the
speedometer. Consult your dealer about the need to change the switch
setting on the back of the speedometer.
Front wheel alignment
If abnormal tire wear or ride and handling characteristics such as vehicle
lead or wander are experienced with properly inflated tires, the front
end alignment should be checked.
Wheel bearing care
Front and rear wheel bearings are adjustable to correct for bearing and
spindle wear. Long bearing life depends upon proper adjustment and
correct lubrication. If bearings are adjusted too tightly (preloaded) they
will overheat and wear rapidly. Loose adjustment will cause pounding
and will contribute to uneven tire wear, steering difficulties and
inefficient brake operation.
Refer to the Ford Service Manual applicable to your vehicle for proper
tightening procedures and torque specifications.
Periodically check the oil level on oil filled front bearing hubs. If
necessary, add oil through the filler plug so the oil level is between the
ADD and FULL marks indicated on the hub. Do not overfill. Overfilling
can result in oil on brake linings.
Refer to your Scheduled Maintenance Guide for fluid level checks and
change intervals for the front hubs.
Your front hubs may be filled with an optional synthetic fluid which
allows use of the extended service intervals. A blue colored filler plug
identifies use of the synthetic fluid.
Maintenance and care

OWNER MAINTENANCE
You can do much of the maintenance your vehicle requires yourself, if
you have the time and a reasonable amount of mechanical ability. If you
prefer to have this work done professionally, your authorized dealer
stands ready to help you.
All mechanical components and attachments are important in that they
could affect the performance of vital components and systems. If
replacement becomes necessary, they must be replaced with parts having
the same part number or with equivalent parts. Torque values of the
attaching parts must be used as specified during any reassembly
procedure to assure proper retention.
EMISSIONS CONTROL SYSTEM
To assure the emissions control systems operate effectively, you should
have the services listed in the maintenance schedule performed at the
specified time and km/mileage intervals. You should avoid running out of
fuel or turning off the ignition while the vehicle is in motion, especially
at high speeds.
Because of high engine compartment and exhaust system
temperatures resulting from emissions equipment, do not park,
idle or operate your vehicle in dry grass or other dry ground cover
where the possibility of ground fire exists.
Do not make unauthorized modifications to the engine or vehicle.
Modifications causing increased amounts of unburned fuel to reach the
exhaust system can significantly increase the temperature of the engine
compartment and/or the exhaust system.
Avoid driving your vehicle if it does not operate properly. If the engine
diesels (more than five seconds of engine run-on after shut-off), misfires,
surges, stalls or backfires, see your dealer. Be alert for fluid leakage,
odor, smoke, loss of oil pressure, or charge indicator or over temperature
warning.
Do NOT use diesel fuel blended with waste oil in engines equipped with
a CATALYTIC CONVERTER-MUFFLER. Waste lube oil blending in fuel
will plug the CATALYTIC CONVERTER-MUFFLER, resulting in a
significant loss of engine power.
