Observation Maintenance Operation
Cleaning the wiper blades with a
clean cloth and mild detergent and
washing with a cleaner does not
restore a clean wipe.Replace wiper blades.
Noisy or difficult to operate. Lubricate body lock cylinders.
Headlamp beams in wrong position
when vehicle operating loaded.Check headlamp alignment.
Windshield washers do not spray
when operated.Check windshield washer fluid
level. Add fluid if required.
1During maintenance and repair, protect the fuel tube and the hose
assemblies, power steering lines, and brake lines from external heat,
acids and abrasions that could damage them.
2Check for (free) linkage action and make sure that (return) spring force
is adequate to maintain pedal free play.
3Adjust, repair or replace, as required, with the same or equivalent parts.
Emissions Control System
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.
To make sure 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 when your vehicle is moving, especially at
high speeds.
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 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 an authorized 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 10000 pounds (4536 kilograms) GVWR.
The following statements concerning prohibited tampering acts and
maintenance and the noise warranty are found in the warranty
information, 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.
Among those acts presumed to constitute tampering are the following
acts listed:
Vehicle System Acts
Acoustical shielding Removal of noise shields, hood blanket, tunnel
liner or acoustical absorptive material.
Engine Removal or rendering inoperative the engine
speed governor to allow engine speed to exceed
manufacturer specifications. Removal of engine
mounted noise shield or oil pan enclosure.
Engine air induction Removal of the air duct, silencer, air cleaner,
and/or air cleaner element and baffle in air
cleaner; re-indexing of air cleaner.

Vehicle System Acts
Exhaust Removal or rendering inoperative exhaust system
components including the catalytic converter -
muffler assembly, inlet pipe, outlet pipe,
resonator and flex pipe. Rotation of horizontal
exhaust system directional outlet pipe to cause
the exhaust to be emitted in a direction other
than the orientation your vehicle was originally
produced with.
Engine cooling Removal or rendering inoperative the fan clutch.
Removal or modification of the fan shroud.
Replacing a fixed fan with a fan of increased
diameter, different number of blades or different
pitch width.
DEF (Diesel
exhaust fluid)Removal or rendering inoperative DEF system
components including the DEF tank, dosing
module, dosing supply module, dosing control
unit, NOx electronic module or NOx sensor.
Emissions Control System(s) Laws
Federal law prohibits vehicle manufacturers, dealers and other persons
engaged in the business of repairing, servicing, selling, leasing or trading
motor vehicles, as well as fleet operators from knowingly removing or
rendering an emissions control device or system inoperative. Further,
modifications of the emissions control system(s) could create liability on
the part of individual owners under the laws of some states. In Canada,
modification of the emissions control system could create liability under
applicable Federal or Provincial laws.
Maintenance
Instructions for maintenance and service of the noise control system
have been included in the required maintenance services and in the
general maintenance section. To further help minimize noise emissions
degradation throughout the life of your vehicle, Ford Motor Company
recommends that you operate this vehicle in the manner described
within this owner’s manual. Caution should be exercised by the owner
when installing replacement parts to be sure that a tampering act (as
outlined above) is not committed. Note any inspection and service
performed in the maintenance log.

Emissions Information Label
Emissions information appears on the Important Engine Information
decal located on or near the engine.
Scheduled Maintenance Services
Maintenance service adjustments must conform to specifications
contained in this manual, and those shown on the Important Engine
Information decal. Perform the following services at scheduled intervals
because they essential to the life and performance of your vehicle. Ford
recommends that you perform maintenance on all designated items to
achieve best vehicle operation.
There are three types of maintenance intervals for general vehicle
environments: On-Highway, City and Severe Service. In all applications,
monitoring miles (kilometers) and time and when the engine is due for
an oil change determine the actual interval. When the engine oil change
is required before the truck lubrication interval, perform the lubrication
at the same time in order to reduce your vehicle’s time out of service.
Air Brake Adjustment
WARNING:Failure to maintain proper air brake adjustment can
result in reduction or loss of braking ability.
A qualified service technician, keeping to the instructions in the service
manual, should perform air brake inspection and adjustment or repairs.
Cam Brakes - Automatic Slack Adjusters
WARNING:Do not manually adjust the automatic slack adjusters
to correct excessive push rod stroke as it may result in reduced
brake effectiveness and a vehicle crash. Excessive push rod stroke
indicates that a problem exists with the automatic adjuster, with the
installation of the adjuster, or with foundation brake components that
manual adjustment does not remedy. Seek service from a qualified
facility for excessive push rod stroke.
Inspect standard air brakes equipped with automatic slack adjusters for
proper brake adjustment as listed in the maintenance schedule charts.

However, inspect the brakes more frequently when subjecting them to
heavy use or adverse operating conditions such as:
•Frequent brake applications while fully loaded.
•Operation on hilly or mountainous terrain.
•Frequent operation on dirt, gravel or mud.
Some aftermarket brake linings also require more frequent inspections.
