2011 FORD F750 engine

Engine starting (parking brake applied)
Air brake check:Check the air brakes in the following manner
(Chock the wheels, if necessary. Push in the
parking brake and on tractors, also push in the
tractor parking brake knob):
1. Check that the air compressor or governor
cut-out pressure is approximately 120 psi
(827 kPa).
2. Turn off the engine, then turn the key back
to the on position, without starting the engine.
3. Without the brake pedal applied, note the
air pressure drop for one minute. It should be
less than 2 psi (14 kPa) for single vehicles and
3 psi (21 kPa) for combination vehicles.
4. Press and hold the brake pedal with 90 psi
(621 kPa) or more and make sure there is no
more than a 3 psi (21 kPa) per minute leak;
for combination vehicles, no more than 4 psi
(28 kPa) per minute.
5. Pump the brake pedal to deplete the system
of air pressure. The warning light and chime
should activate at 57 psi (393 kPa).
6. Pump the brake pedal and make sure the
parking brake and trailer parking brake knobs
pop out at 20 psi (138 kPa) or higher.
Automatic
transmission fluid:With the engine idling at normal operating
temperature and the parking brake applied,
check the automatic transmission fluid. If fluid
needs to be added, place the transmission in
the appropriate gear as specified in the
transmission operator’s manual and refer to
Transmission fluidin theMaintenance and
Specificationschapter.

Water in fuel:During refueling, it
is possible for water-contaminated
diesel fuel to be pumped into your
tank. Your vehicle fuel system is
equipped with a fuel filter/water separator to remove water from the
fuel. The
light will illuminate when the fuel filter/water separator
has a significant quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the fuel
filter/water separator. Refer to your engine operator’s manual for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system.
WARNING:Do not drain water separator while engine is
running. Fuel may ignite if separator is drained while engine is
running or vehicle is moving.
Diesel exhaust fluid:Illuminates
when the diesel exhaust fluid level
falls below 0.5 gallon (1.9L) in the
5 gallon (19.0L) tank or 1 gallon
(3.8L) in the 9 gallon (34.0L) tank.
Refill the tank or, at a minimum,
add at least 1 gallon (3.8L) in the
5 gallon (19.0L) tank or 2 gallons
(7.6L) in the 9 gallon (34.0L) tank to turn off the light.
Diesel particulate filter:
Illuminates if the soot in the DPF
has reached a level where it
requires operator assistance. Refer
toDiesel particulate filterin the
Maintenance and Specifications
chapter and your engine operator’s
manual, for more details.

Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or
in a position between on and start,
or by applying the parking brake
when the ignition is turned to the on position.
If the brake system warning light does not illuminate at this time, seek
service immediately from your authorized dealer. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Parking brake warning:
Momentarily illuminates when the
ignition is turned to the on position
and the engine is off. Also
illuminates when the parking brake
is engaged. If the parking brake
warning lamp does not illuminate at
these times, seek service
immediately.
Vehicles equipped with the Power Park Parking Brake option:If
after setting the parking brake on your vehicle the park brake warning
lamp begins to blink, this may indicate a failure in the parking brake
system. Seek service from your dealer immediately.
