2003 FORD F750 warning

Tires are one of the weaker weight carrying components of the
vehicle. Do not overload the vehicle beyond safe load carrying
capacity.
Avoid hammering rim with steel hammers.
Never run the engine with one wheel off the ground.
Failure to retighten wheel lug nuts as required could allow the
wheel to come off while the vehicle is in motion, possibly causing
loss of vehicle control and collision. Loose wheel studs may also cause
shimmy and vibration.
Use of aftermarket wheel assemblies is not recommended; they
may be incompatible with your vehicle and may result in
equipment failure and possible injury. Replacement with used wheels is
not advised; they may have been treated harshly or have high mileage
and could fail without warning.
A wheel or tire of the wrong size or type may adversely affect
such things as load carrying capacity, wheel and bearing life,
brake cooling, speedometer/odometer calibration, stopping ability,
headlight aim, bumper height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
Maintenance and Specifications
211

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.

induction system (including the
air ducts, the air cleaner, and
the air cleaner element) for
loose fitting, damaged or
missing componentsExcessive noise emanates from the
engine compartment
Inspect the tires and check the
air pressure (*c)Poor steering, wandering or excessive
tire wear
Balance the wheels and the
