PROTECTING THE
ENVIRONMENT
You must play your part in protecting the
environment. Correct vehicle usage and
the authorized disposal of waste, cleaning
and lubrication materials are significant
steps toward this aim.
NOISE POLLUTION CONTROL
In order to keep to the federal exterior
noise regulations, your vehicle may be
equipped with noise emission items.
Depending on your vehicle configuration,
it may have all or some of the following
items:
Air Intake System
Inspect the air cleaner. Do not alter its
location. Do not alter inlet and outlet
piping.
Body
Inspect wheel well splash shields, cab
shields and under hood insulation for
deterioration, dislocation and orientation.
Cooling System
•
Inspect the fan for blade damage. If
you find any damage, replace with the
recommended parts. Inspect for
fan-to-shroud interference and any
damage to shroud, such as cracks and
holes.
• Do not change fan ratio or alter fan
spacer dimensions and positions.
• Inspect fan clutch for proper operation.
Make sure the fan is disengaged when
cooling of the engine is not required.
• Inspect radiator shutters (if equipped)
for proper operation. The shutters
should be open during normal
operating temperatures. Engine
Valve covers and block covers damp-out
engine mechanical noise. If they need
replacing, make sure to replace them with
the recommended parts. Check for
mechanical isolations.
Transmission Enclosure
Inspect for cracks, holes and tears. Clean
any deposits, such as oil, dirt and stones.
Exhaust System
•
Inspect for leaks at various joint
connections and loose clamps.
• Perform a visual inspection for cracks
or holes in the muffler and tail pipe.
• Always use the recommended
replacement parts.
• Do not change the tail pipe elbow or
offset tail pipe orientation from the
standard position as originally received.
• To avoid abnormal changes in vehicle
sound levels, it is necessary for the
owner to perform inspections and
necessary maintenance at specified
intervals. See Scheduled
Maintenance (page 316).

Forced downshifts
•
Allowed in drive (D) with the tow/haul
feature on or off.
• Press the accelerator to the floor.
• Allows transmission to select an
appropriate gear.
Tow/Haul Mode To activate tow/haul, press the
button on the gearshift lever
once. The TOW HAUL indicator
light illuminates in the instrument cluster.
The tow/haul feature:
• Delays upshifts to reduce the frequency
of transmission shifting.
• Provides engine braking in all forward
gears, which slows your vehicle and
assists you in controlling your vehicle
when descending a grade.
• Depending on driving conditions and
load conditions, may downshift the
transmission, slow your vehicle and
control your vehicle speed when
descending a hill, without pressing the
accelerator pedal. The amount of
downshift braking provided will vary
based upon the amount you press the
brake pedal.
The tow/haul feature improves
transmission operation when towing a
trailer or a heavy load. All transmission
gear ranges are available when using
tow/haul.
To deactivate the tow/haul feature and
return to normal driving mode, press the
button on the gearshift lever twice. The
TOW HAUL light deactivates. Tow/haul
also deactivates when you power down
your vehicle. WARNING
Do not use the tow/haul feature
when driving in icy or slippery
conditions as the increased engine
braking can cause the rear wheels to slide
and your vehicle to swing around with the
possible loss of vehicle control. Understanding your SelectShift™
Automatic transmission (If Equipped)
Your vehicle is equipped with a SelectShift
Automatic transmission gearshift lever.
SelectShift Automatic transmission gives
you the ability to change gears up or down
(without a clutch) as desired. Use the buttons on the shifter to lock or
unlock gears and manually select gears.
Press the + button to upshift or the –
button to downshift.

Note:
Installing an exhaust or auxiliary
brake does not necessarily protect the
engine from exceeding maximum governed
speed. Use the primary brakes to make sure
the engine never exceeds maximum
governed speed under any circumstance.
Note: Before starting the engine, make sure
that the exhaust brake switch is in the off
position. Do not turn the exhaust brake on
until the engine has reached normal
operating temperature.
Note: Maximum exhaust brake
performance relates to the type of
transmission your vehicle has.
Note: Engine speed has a major influence
of retarding performance. When engine
speed stays at the maximum allowable
level, the exhaust brake operates at peak
performance.
Note: Exhaust brakes operate effectively
with automatic transmissions, but
performance varies with engine speed and
the gear selected by the transmission.
An exhaust brake is an auxiliary braking
system that assists, but does not replace,
the primary service brake system. It helps
control vehicle speed; it is not a
vehicle-stopping device. A switch on the instrument panel, in
combination with the accelerator and
clutch pedal, allow the operator to make
maximum use of the exhaust brake in the
following conditions:
•
Off-highway driving.
• Mountain driving.
• Heavy traffic.
• High-speed highway driving.
To switch the brake on, push the switch
up. Push the switch down to turn it off.
While approaching a steep grade, make
sure that the exhaust brake switch is in the
on position. The exhaust brake begins
working as soon as you remove your foot
from the accelerator pedal.
Before descending a hill or steep grade,
always select the proper gear. If you take
the transmission out of gear while
descending, it is possible that you cannot
select another gear because of maximum
governed RPM.
125
F-650/750 (TBC) , enUSA, First Printing BrakesE215226

Make sure the engine speed does not
exceed the maximum allowable engine
RPM. Exceeding the maximum allowable
engine RPM can result in damage to the
engine. Apply the service brakes to reduce
the engine RPM or make a slower descent
by using a lower gear.
While going down the grade, use a low
enough gear to descend safely with a
minimum application of the service brakes.
As a general guideline, use the same gear
as you use to ascend the hill.
Exhaust Brake Operating
Characteristics
The exhaust brake turns on when you
remove your feet from both the accelerator
and clutch pedals and the exhaust brake
switch is in the on position. The following
conditions exist if the brake is operating
properly:
•
A slight change in engine sound when
the exhaust brake turns on.
• A smooth braking effect. Do not expect
a retarding effect similar to sudden,
hard application of the service brakes.
• The retarding force possibly felt acting
against your body during brake
application (depending on the grade
and vehicle load). This force is actually
preventing the vehicle from going much
faster.
• Engine temperature remaining in the
normal operating range.
• The tachometer showing a drop in
engine RPM (depending on grade and
vehicle load) during a descent.
• A decrease in road speed when
applying the exhaust brake during a
descent, except when your vehicle is
carrying a heavy load or the grade is
extremely steep. In these instances,
you may need to apply the service
brakes occasionally. TRAILER BRAKES
Trailer Brake Hand Control (If Equipped) WARNING
The hand control should never be
used to apply the brakes when the
tractor and trailer are parked
unattended. Air may leak from the system
and the vehicle could possibly move,
resulting in possible property damage,
personal injury or death. The hand control is located on the
right-hand side of the instrument panel. It
applies the trailer service brakes, which are
independent of the truck or tractor service
brakes.
It operates a valve that provides gradual
control of air pressure applied. When the
valve is only partially applied, you can
override the trailer brakes by pressing fully
on the brake pedal.
To apply the trailer brakes using the hand
control, move the lever downward. The
further you push the lever down, the
greater the air pressure is applied to the
brakes. The lever remains in place until
manually moved.
To release the trailer brakes, move the
lever up completely.

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)
