2016 FORD F750 tires

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least
500 mi
(800 km) before towing a trailer. Make
sure you use the specified engine oil. See
Capacities and Specifications
(page
261).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
GENERAL DRIVING POINTS
General Information
• Accelerate smoothly and evenly. Rapid
acceleration increases fuel
consumption without increasing engine
performance.
• When approaching a hill, press the
accelerator smoothly to start the
incline at full power, and then shift
down as needed to maintain vehicle
speed.
• When going down a hill, or long steep
grades, prevent overspeeding of the
engine. Normally, choose the same
gear to descend the hill that you use to
ascend the hill. The engine governor
has no control over engine speed when
it is being pushed by a loaded vehicle. •
Do not operate in a gear that permits
an engine speed more than the
maximum governed speed or high-idle
RPM (no load).
• Always shift to a lower gear at high
altitudes to prevent engine smoking.
Backing Up WARNINGS
All vehicles have blind spots. To
reduce the risk of severe injury or
property damage, never move your
vehicle to the side or rear or change lanes
without being sure your way is clear on
both sides and to your rear. To reduce the risk of the possibility
of personal injury while backing up
the vehicle, always be sure your
vehicle ’s path is clear. Before backing up your vehicle, be sure you
can do so safely. If anything behind the cab
limits your view, do not rely on mirrors
alone to make sure that your intended path
is clear. If other people are in the vicinity,
have someone standing well behind your
vehicle and outside of your intended path
(visible through an exterior mirror) guide
you as you back up.
Although OSHA or some governmental
regulations may require the use of an
electrical or mechanical back up alarm to
warn bystanders, such an alarm does not
guarantee that the intended path is clear.
When in doubt, get out of your vehicle and
visually check the intended path is clear.
Back up slowly as to allow others time to
move, if necessary.
If you install an electrical back up alarm,
connect it to the backup lamp circuit.

Parking
WARNING
When parking your vehicle, do not
leave the transmission in gear; if the
key is in the on position and the
vehicle rolls, the engine could start. Failure
to follow these instructions could result in
an unattended vehicle moving, possibly
causing personal injury or property
damage. Always use the parking brake. When
parking on a grade, block the wheels and
turn the front wheels to one side so that if
your vehicle rolls, the front tires act against
the curb to stop your vehicle. The front
wheels are more effective at stopping a
rolling vehicle than the rear wheels.
ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at 55 mph [88 km/h] uses 15% less
fuel than traveling at 65 mph [105
km/h]).
• Keep the tires properly inflated and use
only the recommended size. •
Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.
• Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 400 lb [180 kilogram] of
weight carried).
• Driving with the wheels out of
alignment.
Conditions
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 8– 10
miles (12 –16 kilometers) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.

VEHICLE INSPECTION
INFORMATION
To make sure your vehicle is ready to
operate, conduct a pre-trip inspection at
the beginning of each work period. Follow
the steps listed in this section to verify a
proper vehicle inspection procedure.
WARNINGS
Exercise great caution when working
on a vehicle equipped with an
automatic fan clutch. The fan starts
in motion only after the engine coolant
reaches a predetermined temperature or
the refrigerant pressure (if equipped with
air conditioning) reaches a predetermined
setting. The fan starts at this point with no
advance warning. Never reach near, or
permit objects to protrude into, the fan
blade radius while the engine is running as
this could result in vehicle damage,
personal injury or death. WARNINGS
Do not operate the vehicle if any
suspension conditions listed in the
following charts are evident. Loss of
steering or suspension could result in
property damage, personal injury or death. If a wheel must be changed, obtain
expert tire service help. Mounting and
un-mounting of tires should only be
performed by a qualified technician using
necessary safety procedures and
equipment, otherwise the result could be
property damage, personal injury or death. Note:
Always make sure you apply the
parking brake before starting the engine. Engine compartment (with engine off)
Use the dipstick to verify the oil level is in the proper operating
range. See Engine Oil Dipstick (page 185).
Engine oil
Look through the plastic reservoir and verify the coolant level
is within the proper operating range. Do not remove the
pressure cap until the coolant has cooled. See
Engine
Coolant Check (page 190).
Engine coolant
Verify that the fluid level is in the proper operating range. See
Power Steering Fluid Check
(page 202).
Power steering fluid
Remove the master cylinder caps and inspect the fluid level.
See
Brake Fluid Check (page 201).
Brake fluid

F650750 (TBC), enUSA, First Printing Vehicle Inspection Guide

Rear brakes
Inspect for cracked, worn or frayed hoses, and that all coup-
lings are secure.
Hoses
Verify that there are no cracks or dents, and that the cham-
bers are securely mounted.
Brake chambers
Inspect for broken, loose or missing parts.
Slack adjusters
Note: The angle between the push rod and adjuster arm
should be approximately 90 degrees when the brakes are
applied. When pulled by hand, the push rod should not move
more than approximately
1 in (2.5 cm).
Verify that there are no cracks, dents, holes, and no loose or
missing bolts and that the brake linings are not worn,
dangerously thin or contaminated by lubricant.
Drums Rear wheels
Check for even separation of dual wheels, and that the tires
are not touching each other.
Spacers
Inspect for damaged or bent rims. They should not have
welding repairs, and there should be no rust trails, which
indicate it is loose on the wheel.
Rims
Verify all lug nuts are present and not loose (look for rust
trails around the lug nuts). There should be no cracks radiating
from the lug bolt holes or distortion of the bolt holes.
Lug nuts
Trailer
If you are pulling a trailer, perform an
inspection of the trailer similar to that of
the tractor. The inspection should follow
trailer manufacturer recommendations
and should include at a minimum: general
condition, landing gear, doors, sides, lights,
reflectors, suspension, brakes, tires,
wheels, cargo placement, stability and
tie-downs. Transmission WARNING
If the unit starts in gear and/or the
neutral start switch is not functioning
correctly, the vehicle may
inadvertently move which could result in
property damage, personal injury or death. Regularly inspect the transmission's
neutral start switch. The engine should
only start in neutral (N) or park (P) (if
equipped with a park position).

inspection and keep to instructions
provided by the service manual.
Hydraulic brake systems are
power-assisted. There is a great
reduction in braking capabilities
without engine assist.
• Proper fluid level. The level should be
at the bottom edge of the ring on each
reservoir fill port. Do not fill the master
cylinder to the top of the reservoir. If
fluid level requires attention to
maintain a proper master cylinder level,
this is an indication of either severe
operation (pad wear) or fluid leakage.
A more frequent and thorough brake
inspection is required.
• Brake lines, hoses and fittings. Repair
or replace brake line tubes, hoses or
fittings as required. Inspect these
components every 4,000 mi
(6,000 km) for the following.
• Lines for kinks, dents, corrosion or
rupture.
• Hoses for abrasions, kinks, soft
spots or rupture, collapse, cracks,
twists or loose frame supports.
When replacing a hose, be sure
there is adequate clearance to the
hose to avoid an abrasion to the
new hose.
• All connections for leaks.
Driveline Parking Brake WARNING
Use wheel chocks and exercise
caution when inspecting under the
vehicle. A vehicle roll-away could
result in property damage, personal injury
or death. A qualified technician should adjust the
parking brake and keep to the instructions
in the service manual. AXLE INSPECTION
Front Axle
Maintaining the front axle alignment to
specifications is very important. A qualified
technician should check and maintain the
alignment.
Regular inspections should include:
•
Toe-in inspection and adjustment (if
necessary), particularly with radial
tires.
• Checking for proper tightness of axle
mounting U-bolt nuts, attaching or
mounting bolts and nuts.
• Checking the axle for damage, binding,
worn parts and adequate lubrication.
• Checking the kingpins for excessive
wear. Also, perform this check during
other scheduled maintenance, for
example as tire rotation or service,
wheel bearing service and alignment.
See the workshop manual for proper
procedures.
Toe-in
It is essential to maintain correct toe-in
and tire pressure for optimum tire wear.
Inspecting steer axle tires in the first
3,000– 10,000 mi (5,000– 16,000 km)
generally shows if tires are wearing
normally.
Rapid outside shoulder wear on both tires
indicates too much toe-in.
Rapid inside shoulder wear on both tires
indicates too much toe-out.
In P&D-type service, there can be a
left-to-right steer tire tread life differential
up to 40% depending on routes and other
variables.
221
F650750 (TBC), enUSA, First Printing Maintenance

Follow the tire manufacturer's
recommended cold inflation pressure for
the tire size, load range (ply rating) and
steer axle loading typical for their operation
(each steer axle tire equals ½ steer axle
loading).
Special applications may warrant a setting
based on experience with the type of tire
operating loads and conditions. Radial tires
are more sensitive to toe-in setting than
bias ply tires. Fine tuning school bus
alignment to line-haul truck standards
does not drastically improve tire tread life.
STEERING SYSTEM
INSPECTION
WARNING
Failure to maintain the steering
system in proper condition can cause
reduced steering ability resulting in
property damage, personal injury or death. Note:
Have any steering problems
immediately corrected by a qualified service
technician.
Ask your service technician to examine the
steering mechanism. Only minor
adjustments may be necessary.
Regular inspections should include:
• Checking the tie rod, drag link end
clamp bolts and ball joints for proper
tightness.
• Checking for installation and spread of
cotter pins and tightness of nuts at
both ends of the tie rod and drag link.
• Checking that the pitman arm (steering
arm at steering gear) mounting is tight
and locked. Check system for leaks or
hose chafing. Repair immediately, if
necessary. •
Maintaining proper steering gear and
power steering pump lubricant levels.
• Checking steering column joint bolts
and steering linkage, particularly for
body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check
steering column joint bolt tightness every
60,000 mi (96,000 km) or annually,
whichever occurs first. Do not overtighten
the bolts.
Hydraulic System
Whenever draining and refilling the power
steering's hydraulic system for any reason,
bleed air from the system before returning
the vehicle to service. Failure to bleed the
hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware
of the proper procedures for filling and
bleeding the system.
SUSPENSION SYSTEM
INSPECTION
Note: Do not adjust air suspension height
to any setting other than the specified
setting. Altering the height setting changes
the driveline angle and may result in
unwarrantable component damage, such
as transmission component damage.
Verify drive axle air suspension height and
height control valve performance at engine
oil change intervals.
Periodically check:
• Condition of spring leaves for evidence
of fatigue, bending or breakage.
• Condition of suspension mounting
brackets and bushings.
• Torque rod mounting fasteners for
tightness.

Engine
•
Change the engine oil and filter prior to
storage because used engine oil
contains contaminates which may
cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast idle
with the climate controls set to defrost
until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
Cooling system
• Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery,
we recommend that you disconnect
the battery cables to maintain battery
charge for quick starting.
Note: It is necessary to reset memory
features if battery cables are disconnected. Brakes
•
Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle
15 ft (4.5 m) back and
forth to remove rust build-up.
• Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.
