GENERAL SERVICING GUIDELINES AND PRECAUTIONS
Always use care when performing vehicle maintenance, repairs or system
checks. Improper or incomplete service could result in the vehicle not
working properly which may result in personal injury or damage to the
vehicle or equipment. It is the operator’s responsibility to see that the
vehicle receives proper care and maintenance. If you have any questions
about performing service, have the service done by a qualified
technician.
Servicing guidelines
When servicing your vehicle, always:
•wear safety glasses for eye protection.
•do not wear loose-fitting clothing, hanging jewelry, watches or rings.
•do not smoke.
•set the parking brake or chock the wheels.
•use support stands, not a jack, when working under a raised vehicle.
•turn off the ignition unless a procedure requires the engine to be
running.
•operate the engine in a well-ventilated area.
•do not work on the brakes or the clutch unless the proper precautions
are taken to avoid inhaling friction material dust.
•avoid contact with hot metal parts. Allow the components to cool
before working with, or around, them.
Quality service parts are available through your dealer. If dealer parts are
not used, make sure the replacement parts are of equivalent quality.
WARNING:The use of inferior parts can adversely affect the
quality and reliability of your vehicle which, in turn, can result in
property damage, personal injury or death.
Note:To avoid damage to the vehicle’s electrical components prior to
electric welding:
•disconnect both battery cables.
•attach the welder ground cable as close as possible to the part being
welded.
•if it is necessary to weld close to an electrical component, it is
recommended that the component be temporarily removed.

Cleaner air - gasoline engines
Ford endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality, per the recommendations in theChoosing the right
fuelsection.
Running out of fuel - diesel engines
Avoid running out of fuel as this allows air to enter the fuel system,
which makes restarting the vehicle difficult.
If you have run out of fuel:
•If your vehicle is equipped with dual fuel tanks,add at least
4–5 gallons (15–19 liters) of fuel to each tank before attempting to
restart the engine.
•The fuel system must be primed before attempting to restart the
engine. Refer to the engine operator’s manual for instructions on
priming the engine.
•Use caution not to overheat and damage the starterby cranking
the engine for an excessive period of time. You may need to crank the
engine for a longer time than normal. If the engine fails to start in
30 seconds, turn the ignition to the off position and wait for two
minutes before cranking the engine again.
•Any remaining trapped air self-purges from the fuel system once the
engine starts running.
•The engine may run rough and produce white smoke while air is in
the fuel system. This is normal and should stop after a short period of
time.
Running out of fuel - gasoline engines
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.
•If your vehicle is equipped with dual fuel tanks,adding
4–5 gallons (15–19 liters) of fuel is enough to restart the engine. If the
vehicle is out of fuel and on a steep grade, more than 4–5 gallons
(15–19 liters) may be required.

EMISSIONS CONTROL SYSTEM
To ensure the emissions control systems operate effectively, you should
have the services listed in the maintenance schedule performed at the
specified time and mileage intervals. You should avoid running out of fuel
or turning off the ignition while the vehicle is in motion, especially at
high speeds.
WARNING: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.
Vehicles equipped with a diesel engine CANNOT use diesel fuel blended
with waste oil if equipped with a catalytic converter-muffler. Waste lube
oil blending in fuel plugs the catalytic converter-muffler, resulting in a
significant loss of engine power.
Noise emissions warranty, prohibited tampering acts and
maintenance
On January 1, 1978, Federal regulations became effective governing the
noise emissions on trucks over 10,000 lb. (4,536 kg) GVWR. The
following statements concerning prohibited tampering acts and
maintenance and the noise warranty are found in the Warranty Guide,
and are applicable to completed trucks.
Tampering with noise control system prohibited
Federal law prohibits the following acts or the causing thereof: (1) The
removal or rendering inoperative, by any person other than for purposes
of maintenance, repair or replacement, of any device or element of
design incorporated into any new vehicle for the purpose of noise control
prior to its sale or delivery to the ultimate purchaser or while it is in use,
or (2) the use of the vehicle after such device or element of design has
been removed or rendered inoperative by any person.
