2007 FORD F750 air condition

When the Traction Controlswitch,
located on the instrument panel, is
activated standard Traction
Control will change to Off Road
traction mode, the traction control
light will be illuminated and flash
slowly. If a traction event occurs, in
either mode the traction control
light will flash rapidly. The standard
Traction Control can be selected
by pushing the Traction Control 
switch again or will be automatically selected at next ignition cycle.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching to the Off Road Traction Control mode. This may
allow excess wheel spin to “dig” the vehicle out and enable a successful
“rocking” maneuver.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a Traction Control 
event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
AIR SUSPENSION (IF EQUIPPED)
Note: The vehicle must not be operated without air in the suspension
springs. Operating the vehicle without air in the air suspension springs
will damage the suspension, degrade ride performance and may cause
property damage.
The suspension system automatically adjusts to different loads to
maintain a constant frame height. The system allows for ease of vehicle
loading and provides improved vehicle ride and increased driver comfort.

•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
• If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCW, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to Lubricant specifications in theMaintenance and
Specifications chapter for the lubricant specification. Remember that
regardless of the rear axle lube used, do not tow a trailer for the first
500 miles (800 km) of a new vehicle, and that the first 500 miles (800
km) of towing be done at no faster than 70 mph (112 km/h) with no
full throttle starts.
• After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
• To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park)
(if available on your automatic transmission) or N (Neutral) (manual
transmissions and automatic transmissions withou taP[Park]
position).
• Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
FIFTH WHEEL OPERATION
Failure to follow the fifth wheel manufacturer’s instructions for
hooking and unhooking as well as sliding the fifth wheel could
result in an accident, personal injury or death.
When the tractor and trailer are parked unattended, the trailer
brake hand control should never be used to apply the brake,
since air may leak from the system, allowing vehicle movement,
resulting in possible property damage, personal injury or death.
Before hook-up, make sure:
• The fifth wheel jaws are fully opened.
• The fifth wheel is fully tilted back to prevent body damage when the
tractor is backed under a trailer.
• The trailer wheels are blocked and the trailer spring brakes are
adjusted and applied. Never chase a trailer.
• The brake hoses and light cords are clear of the fifth wheel.

3. Remove the jumper cable from the positive (+) terminal of the booster
vehicle’s battery.
4. Remove the jumper cable from the positive (+) terminal of the
disabled vehicle’s battery.
After the disabled vehicle has been started and the jumper cables
removed, allow it to idle for several minutes so the engine computer can
relearnits idle conditions.
WRECKER TOWING INSTRUCTIONS
Before moving the towed vehicle, check for adequate road clearance of
vehicle components. It is recommended the towed vehicle be unloaded
prior to being towed to reduce any abnormal load to the vehicle
components resulting from the towing procedures. Before towing, be
sure to fully release the parking brake. The spring-actuated type parking
brake can be reset by recharging the air system with at least 64 psi (441
kPa) of air. If the brake system will not retain air pressure, then the
spring brakes must be released manually. Refer toParking brakein the
Drivingchapter
Note:For towing, make sure the vehicle is securely connected to the
tow vehicle and the tow vehicle parking brakes are applied before
releasing the disabled vehicle’s spring brakes.

Follow the periodic lubrication procedures and regular inspection
intervals as outlined. Have your dealer or service center inspect your
vehicle at least once a year. Remember that regular maintenance and
replacement of worn components will usually prevent serious problems
from developing later.
Making modifications to various parts, components and systems
of the vehicle, such as brake and steering systems can adversely
affect the quality, reliability and operation of your vehicle and could
result in property damage, personal injury or death. Such modifications
must be avoided.
The lubrication intervals present a good opportunity to inspect the
vehicle. It is suggested that the various points listed herein be checked
at the lubrication or other recommended intervals.
Failure to properly perform maintenance and servicing
procedures could result in vehicle damage, personal injury or
death.
If the owner/operator of the vehicle is a skilled technician and intends on
performing the vehicle maintenance and service, he is strongly urged to
purchase a service manual.
Take care when performing any maintenance, system check or
service on your vehicle. Some of the materials may also be
hazardous if used, serviced or handled improperly and could result in
property damage, personal injury or death.
Air conditioning system checks
Have your air conditioning system checked each spring. The refrigerant
charge, cleanliness of the condenser-evaporator cores and belt condition
are essential to air conditioning performance.
When the air conditioning system is being used daily, remove the fresh
air filter (if equipped) once each season and check for dirt, lint, etc.
Replace the filter if necessary. Vehicles operating in unusually dusty
conditions may require inspecting and replacing the fresh air filter more
often.
Front axle - general service information
Maintaining the front axle alignment to specifications is very important
and should only be performed by a qualified technician. Toe-in
adjustment is particularly important with radial tires.

Brake system - general inspection
Your vehicle is equipped with non-asbestos brake linings. However,
exposure to excessive amounts of brake material (whether asbestos or
non-asbestos, fiberglass, mineral wool, aramid or carbon) may be a
potentially serious health hazard.
Note:Persons handling brake linings should follow all precautions listed
below:
1. Always wear a respirator approved by the National Institute of
Occupational Studies of Health (NIOSH) or Mine Safety and Appliance
(MSA) during all brake service procedures. Wear the respirator from
removal of the wheels through assembly.
2.Neveruse compressed air or dry brushing to clean brake parts or
assemblies.
3. Clean brake parts and assemblies in open air. During assembly,
carefully place all parts on the floor to avoid getting dust in the air. Use
an industrial vacuum cleaner with a HEPA filter system to clean dust
from the brake drums, backing plates and other brake parts. After using
the vacuum, remove any remaining dust with a rag soaked in water and
wrung until nearly dry.
4.Neveruse compressed air or dry sweeping to clean the work area.
Use an industrial vacuum cleaner with a HEPA filter system and rags
soaked in water until wrung until nearly dry. Dispose of used rags with
care to avoid getting dust in the air. Use an approved respirator when
emptying vacuum cleaners and handling used rags.
5.Worker clean-up:
Wash your hands before eating, drinking or
smoking. Vacuum your work clothes after use and then launder them
separately, without shaking them, to prevent fiber dust getting into the air.
Air brakes - inspection and adjustment
A regular schedule for periodic cleaning, lubrication, adjustment and
inspection should be established based on the type of vehicle operation.
It is difficult to predetermine an exact maintenance interval (time or
mileage), since vehicles will be used in a wide variety of applications and
conditions. If you are uncertain of the proper schedule and procedures
for your vehicle, contact your dealer.
Periodic checking of push rod travel or brake adjustment is essential for
effective braking. Push rod travel should be checked every service
interval to determine if adjustment is necessary. Brake chamber push
rods on original equipment chambers now incorporate a stroke indicator
to aid in adjustment checks; an orange paint marker near the base of the
push rod. If the push rod is clean and the brakes require adjustment, the
orange marker can be seen protruding from the chamber when the
brakes are applied.

Do not manually adjust the automatic slack adjusters to correct
excessive pushrod stroke as it may result in reduced brake
effectiveness and a vehicle crash. Excessive pushrod stroke indicates
that a problem exists with the automatic adjuster, with the installation
of the adjuster, or with foundation brake components that manual
adjustment will not remedy. Seek service from a qualified facility for
excessive pushrod stroke.
Inspect the brake lining every maintenance interval. When brake lining or
blocks are worn to within 1/16 inch (1.6 mm) of rivets, brake lining must
be replaced. This inspection or adjustment should only be performed by
a qualified technician and must be in accordance with instructions
provided by the service manual.
Do not back off or disconnect the front brakes so that they are less
effective, letting the rear brakes do all the stopping of the vehicle. Do
not overlook the brakes on the trailer, either. Brake condition on the
trailer is just as important as the tractor. Proper brake balance on trucks
and tractor-trailers is essential for effective braking.
Once a year, the entire brake system must be inspected. Check the
following:
• Any rubber as it may deteriorate whenever used. Rubber brake
components should be inspected by a qualified technician and
replaced as necessary. Replacement intervals vary according to the
severity and length of vehicle service.
• Condition of brake drums, brake chambers and slack adjusters.
• System for air leaks.
• Hose or pipes for rust, damage and deterioration.
• Operation of service and parking brakes.
Some parts such as air brake chamber diaphragm, air compressor and air
cleaner should be inspected periodically and replaced if considered
unserviceable.
Air brakes - air dryer
Performance of desiccant or after-cooler type air dryers is dependent on
climatic conditions in which your vehicle is operating. Maintenance
schedules must be established for each specific operation.
The use of an air dryer on a vehicle does not eliminate the need to
periodically drain the air reservoirs.

Air brakes - desiccant air dryer
Inspect for moisture in the air system by opening reservoirs, drain cocks
or valves and checking for presence of water. The presence of small
amounts of water due to condensation is normal and should not be
considered as an indication that the dryer is not functioning properly.
The desiccant cartridge should be replaced or rebuilt when it has been
determined that the desiccant is contaminated and does not have
adequate water absorption capacity. The desiccant change interval may
vary; it is generally recommended that the desiccant be replaced every
12 months (yearly). If experience has shown that extended or shortened
life has resulted for a particular installation, then the yearly interval can
be increased or decreased accordingly.
Hydraulic brakes - inspection and adjustment
A regular schedule for periodic cleaning, lubrication, adjustment and
inspection should be established based on the type of vehicle operation.
It is difficult to predetermine an exact maintenance interval (time or
mileage), since vehicles will be used in a wide variety of applications and
conditions. If you are uncertain of the proper schedule and procedures
for your vehicle, contact your dealer.
Inspect the brake lining every maintenance interval. Establish inspection
intervals that provide for lining replacement before damage to the disc
occurs. Excessive lining wear may expose the backing plate to the disc
causing scoring of the disc faces.
This inspection should be performed by a qualified technician and must
be in accordance with instructions provided by the service manual.
Note:Hydraulic brake system are power assisted. Braking capabilities
will be greatly reduced without engine assist.
Hydraulic brakes - fluid level
Fluid 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.
Note: If brake fluid requires attention to maintain a proper master
cylinder level, this is an indication of either severe operation (pad wear)
or fluid system leakage. A more frequent and thorough brake inspection
will be required.
Hydraulic brakes - fluid precautions
The HydroMax brake system consists of two completely separate
hydraulic systems operating with two different and incompatible fluids;
