2015 FORD F750 brake

Note:Do not increase engine speed until the oil pressure gauge
indicates normal pressure. The oil pressure gauge should indicate this
within 15 seconds after starting.
Note:Idle the engine for three to five minutes before operating with a
full load.
Note:Try to limit engine idle to 10 minutes. Excessive idling reduces
fuel economy.
Vehicles with a Manual Transmission
Note:Do not touch the accelerator pedal.
1. Fully press the clutch pedal.
2. Start the engine.
Vehicles with an Automatic Transmission
Note:Do not touch the accelerator pedal.
1. Select positionN,orP(if equipped with a Park position).
2. Fully press the brake pedal.
3. Start the engine.
Starting the Engine with the Vehicle on a Steep Grade
When starting a diesel engine when the loaded vehicle is on a grade, the
engine RPM starts to fall slightly when you engage the clutch. Do not
disengage the clutch and try to increase engine RPM as this may damage
driveline components. The engine recovers as the vehicle begins moving.
DIESEL PARTICULATE FILTER (DPF)
WARNING:The normal operating temperature of the exhaust
system is very high. Never work around, or attempt to repair, any
part of the exhaust system until it has cooled. Use special care when
working around the diesel particulate filter. The DPF heats up to a high
temperature after only a short period of engine operation, and can
remain hot even after the engine is turned off. Failure to follow these
instructions may result in serious personal injury.
Your vehicle is equipped with a diesel particulate filter (DPF), as part of
the after-treatment exhaust system, to trap soot and other large particles
produced by the engine combustion process. You must periodically
reduce the soot that accumulates in the filter to prevent excessive
exhaust restriction. The engine and after-treatment system generally
perform the soot reduction process, also known as “filter regeneration,”
automatically.

Instrument cluster lamp(s) illuminates or flashes when operator
assistance is required. In addition, engine performance becomes
increasingly limited above Level 1.
At Levels 1 and 2, the operator can take two courses of action to
facilitate filter regeneration:
1. Drive your vehicle on the highway at highway speeds.
2. Perform a parked regeneration by following the steps inParked
regeneration.
At Level 3, performing a parked regeneration is the only available course
of action (short of professional servicing) available to the operator for
regenerating the filter. At Level 4, professional servicing is the only way
to regenerate the filter.
Parked Regeneration
WARNING:When performing the parked regeneration
procedure, make certain the vehicle is safely off the roadway, and
the exhaust system is away from people, or any flammable materials,
vapors, or structures. Engine speed may increase during parked
regeneration.
Note:Parked regeneration is only available when the DPF lamp on the
instrument cluster is illuminated solid or flashing.
1. Bring your vehicle to a complete stop on level ground and safely off
the road with the exhaust system away from people, flammable
materials, vapors or structures. Ford recommends that you perform a
walk-around before beginning a parked regeneration.
2. If your vehicle is equipped with an automatic transmission and a
steering column shift lever, place the transmission in positionP.
Otherwise, place the transmission in positionN.
3. Remove your feet from the accelerator pedal and clutch pedal
(manual transmission).
4. Set the parking brake.
5. Within five seconds of setting the parking brake, remove your foot
from the service brake pedal.
The engine speed may increase slightly. To allow parked regeneration to
continue uninterrupted:
1. The vehicle must remain parked.
2. The transmission must remain in positionPorNas previously
described in Step 2.

3. Do not press the accelerator pedal, service brake pedal, or clutch
pedal (manual transmission).
4. The parking brake must remain set.
On average, depending on filter level and other factors, the process takes
20–30 minutes to complete. The DPF lamp turns off when the process is
complete. Repeat Steps 1–5, if parked regeneration is interrupted.
To Discontinue Parked Regeneration
Press any of the floor pedals to discontinue parked regeneration.
Maintenance and Service
The DPF can retain a relatively large amount of residual ash and provide
many miles and hours of maintenance-free operation. At some point,
generally beyond 150000 miles (240000 kilometers) or 5000 hours of
operation (whichever comes first), the DPF requires professional
cleaning to remove the accumulated ash.
The exact number of miles or hours of operation vary greatly depending
upon vehicle and engine loading and operating conditions, ash content of
the engine oil, and quality of the diesel fuel used in your truck. Adhering
to your engine manufacturer’s recommended oil and fuel specifications
maximizes the miles and hours of operation before a DPF professional
cleaning is required. See your engine manufacturer’s owner’s manual for
more details about recommended maintenance and service of your DPF.
Exhaust Outlet Assembly
WARNING:The normal operating temperature of the exhaust
system is very high. Never work around or attempt to repair any
part of the exhaust system until it has cooled. Failure to follow these
instructions may result in serious personal injury.
Note:Do not modify or remove this device. Modification of the system
or additions of aftermarket devices can reduce the effectiveness of the
system, as well as cause damage to the exhaust system or engine. Any
modifications may also invalidate the vehicle or engine warranty. See
your warranty information.
Note:Blocked or plugged holes or modification to, or removal of, the
outlet assembly could result in elevated exhaust temperatures that may
result in vehicle or property damage or personal injury.
The exhaust outlet assembly on your vehicle is a uniquely functioning
device that accompanies the DPF assembly. It can help control the
temperature of the exhaust during the DPF regeneration process.

more quickly. If you force the gearshift lever into position, this action
defeats the purpose of the synchronizer by causing gear clash.
Shifting with a Non-Synchronized Transmission
SeeClutch brakeandDouble clutch proceduresin theClutchsection
of this chapter.
Clutch
Do not ride or slip the clutch as this causes unnecessary heat and wear.
Maintain the specified clutch adjustment to prolong its life and regularly
inspect the clutch control linkage for tightness. See theScheduled
Maintenancechapter for other maintenance information. When
adjustment of the clutch is necessary, it is very important that the work
be performed properly or early clutch failure may result and a costly
clutch overhaul may become necessary. Only a qualified technician
should perform clutch work.
Note:Continued use of a damaged or worn clutch, prolonged clutch
slippage or downshifting at excessive speeds can result in a failure of the
engine, transmission or clutch components.
Note:To avoid premature clutch wear and failure, do not drive with
your foot resting on the clutch pedal or use it to hold your vehicle at a
standstill on an upgrade as when waiting for a traffic light.
Engaging the Clutch
•Always start in the proper gear. An empty vehicle can start in a
higher gear than a fully loaded vehicle. Starting in too high a gear can
cause clutch slippage and excessive heat and wear on the clutch. A
gear that starts the vehicle moving at idle speed is the correct gear. If
you have to rev the engine to get your vehicle going, the gear
selection is too high.
•Do not shift until your vehicle has reached the proper speed.
Upshifting before your vehicle has reached the proper speed can
cause clutch slippage and excessive heat and wear on the clutch.
•Never hold a vehicle on a grade with the clutch. This causes the
clutch to slip and can actually burn up the clutch.
•Never coast with the clutch disengaged. The high RPM (sometimes
over 10000) can actually burst the facing material of the clutch.
•Never engage the clutch while coasting. Re-engaging the clutch after
coasting may not only cause a great shock to the clutch, but the
whole drivetrain. Internal engine damage or clutch and flywheel
failure can result from this.

If the transmission is equipped with a ceramic clutch, you must start
your vehicle moving in first gear and engage the clutch before pressing
the accelerator at idle. In addition, do not try to slip the clutch by raising
engine RPM and riding or feathering the clutch pedal since this causes
erratic engagement that can cause engine stalling and potential serious
damage to driveline components.
Clutch Brake (Non-Synchronized Transmissions) - Vehicle
Stationary
A clutch brake stops transmission input shaft rotation so you can
accomplish the initial first gear or reverse gear selection when your
vehicle is stationary and the engine is at idle speed. Clutch brake
application occurs in the last 1 inch (25 millimeters) of clutch pedal
travel.
When using the clutch brake, fully press the clutch pedal and shift the
transmission into first gear or reverse. If the transmission does not go
into one of these gears, slowly release the clutch pedal while applying
light pressure on the transmission shift lever until it shifts into gear.
Note:After engagement of first gear, do not use the clutch brake for
upshifting or downshifting. If you do, clutch brake life shortens and gear
selection shift efforts may increase.
Double-Clutch Procedures - Non-Synchronized Transmissions
In order to properly upshift or downshift:
1. Press the clutch pedal to disengage the clutch.
2. Shift the transmission into neutral.
3. Release the clutch pedal.
If upshifting, wait until the engine speed matches the transmission speed
of the gear you are selecting.
If downshifting, accelerate the engine until the engine speed matches the
input speed of the gear you are selecting. Press the clutch pedal
immediately and shift into the desired gear, then release the clutch
pedal.

Spicer ES56-7B and ES066-7B 7-speed
These transmissions are equipped with seven forward
gears and one reverse; 2–7 are synchronized gears. The
shift pattern is on the gearshift knob.
Do not shift the transmission into first gear or reverse while your vehicle
is moving as this could damage the transmission.
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
WARNING:Hold the brake pedal down while you move the
gearshift lever between positions. If you do not hold the brake
pedal down, your vehicle may move unexpectedly and cause property
damage, personal injury or death.
Main transmission, auxiliary transmission, transfer case and power
take-off (PTO) control shift patterns can be found on a placard or decal
on the driver’s sun visor, on the instrument panel or on the shift control
itself.
Use the main transmission control to select the various gear ratios or
speeds of the transmission. Selecting position D does not change the
transmission gear ratio, but for use where the gear ratios in the main
transmission are adequate to handle the vehicle operation.
If the transmission fails to shift properly, check the inline 10A fuse
located in the battery cables above the battery.

Brake-shift Interlock
Vehicles equipped with a gasoline engine have a brake-shift interlock
feature that prevents you from moving the gearshift lever from position
Pwhen the ignition is in the on position and the brake pedal is not
pressed.
If you cannot move the gearshift lever out of positionPwith the ignition
in the on position and the brake pedal pressed, it is possible that a fuse
has blown or your vehicle’s brake lamps are not operating properly. See
theFuseschapter.
WARNING:Do not drive your vehicle until you verify that the
brake lamps are working.
WARNING:When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
