2001 FORD F650 brakes

Operation
Push the rocker switch up to turn
the exhaust brake on. The switch
will illuminate in the ON position.
Push the switch down to turn the
brake off.
Starting engine
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 temperatures.
Driving downhill
While approaching a steep grade, make sure that the exhaust brake
switch is in the ON position. The exhaust brake actuates as soon as you
remove your foot from the accelerator pedal. 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 would to ascend the hill.
Before descending a hill or steep grade always select the proper gear. If
the transmission is taken out of gear while descending it is possible that
you will not be able to select another gear because of maximum RPM
being governed.
Make sure the engine speed does not exceed the maximum
allowable engine RPM. Exceeding the maximum allowable engine
RPM will 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.
The exhaust brake is not recommended for use on slippery or
low traction road surfaces. Under these conditions a loss of
vehicle control could possibly occur.

Exhaust brake operating characteristics
When you remove your feet from both the accelerator and clutch pedals
and the exhaust brake switch is in the ON position, the exhaust brake is
activated. The following conditions should exist if the brake is operating
properly:
²A slight change in the sound of the engine when the exhaust brake is
activated.
²Exhaust smoke appears normal.
²Engine temperature remains in the normal operating range.
²Road speed usually decreases when the exhaust brake is applied
during a descent, except when the vehicle is carrying a heavy load or
the grade is extremely steep. In these instances, you may need to
apply the service brakes occasionally.
²During a descent, the tachometer usually shows a drop in RPM
depending on the grade and the vehicle load.
²Do not expect a retarding effect similar to sudden hard application of
the service brakes. The exhaust brake retards the vehicle with a
smooth braking effect.
²Depending on the grade and vehicle load, you may or may not feel the
retarding force acting against your body when the brake is applied.
The brake's retarding force is actually preventing the vehicle from
going much faster.
Make sure the exhaust brake is turned off before shutting off the engine.
Installing an exhaust or auxiliary brake should never allow the
engine to exceed maximum governed speeds under any
conditions. Refer to theStartingchapter.
Air brake reservoir draining
Failure to drain air brake reservoirs can result in a reduction or
loss of braking ability due to fluid accumulation in the reservoir
and/or possible freeze-up during cold weather.

Do not allow your vehicle to coast in N (Neutral). Engine
braking is not available in N (Neutral). Allowing your vehicle to
coast in N (Neutral) may result in loss of vehicle control and severe
internal transmission damage.
D (DriveÐNormal driving position)
In this position, the transmission starts in first gear and automatically
shifts through second, third, fourth and fifth depending on load and
speed demands. When the vehicle is slowing down, the transmission will
automatically downshift. This range is used for highway driving under
normal conditions.
4 and 2 (Fourth and Second)
Use this position when road, load or traffic conditions make it desirable
to restrict the automatic shifting to a lower range. These ranges provide
greater engine braking than D (Drive). When conditions no longer
require these lower gears, shift back to D (Drive).
1 (First)
The transmission has to be manually shifted into 1 (First) and will not
shift into a higher gear. Use this position when pulling through mud or
snow, driving up steep grades, hauling extra heavy loads or where
maximum reduction is required.
Power take-off (PTO) operation with an Allison automatic
transmission (except MD applications and vehicles equipped with
a Caterpillar 3126E engine)
The power take-off can be operated while the vehicle is standing or
moving.
To engage the PTO, apply the brakes and shift to any gear other than N
(Neutral) - this stops the rotation of the PTO drive gear in the
transmission - then engage the PTO.
If engagement is prevented by the gear teeth not meshing properly,
release the brakes and allow the vehicle to creep slightly - or shift the
selector to N (Neutral) and then back in gear. The PTO should never be
engaged by clashing the gear teeth. This may damage the PTO unit and
the transmission PTO drive gear teeth. This could result in further
damage to the transmission and PTO.

MAXIMUM VEHICLE LOADING
Every vehicle manufactured by Ford
Motor Company is supplied with
information on the Vehicle Rating
Decal listing the maximum loading
for the vehicle (GVWR), and its axle
systems (GAWR) at the tire to
ground interface.
Under no circumstances should your vehicle be loaded in excess of the
GVWR or GAWR. It is the operator's responsibility to assure that neither
the axle capacities, spring capacities, tire capacities nor the vehicle rated
GVWR is exceeded. For tire capacities, refer toSpecifications and
capacitieschapter.
Unloaded or lightly loaded vehicles
The braking system has been designed to safely stop your vehicle when
fully loaded to its GVWR.
When operating empty or lightly loaded, sudden or hard braking
may induce wheel lockup with loss of vehicle control and the
possibility of accident and serious injury, especially on wet or slippery
road surfaces.
Driving through water
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine's air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.

Connecting the jumper cables
1. Position the vehicles so that they
do not touch one another.
2. Apply the parking brakes.
3. Switch off the engine and any
unnecessary electrical equipment.
4. Find the positive (+) terminal of
the discharged battery.
5. Using the jumper cables, connect
the positive (+) terminal of the
discharged battery to the positive
(+) terminal of the booster battery.
Note: In the illustration, lightning
bolts are used to designate the
assisting (boosting) battery.
6. Connect one end of the cable to
the negative (-) terminal of the
booster battery and the other end to
a ground at least 12 inches from the
battery of the discharged vehicle.
The vehicle frame is usually a good ground.
7. Ensure that the jump leads are clear of moving parts of the engine,
and that the clamps from one cable do not touch the clamps on the
other cable.
8. Do not lean over the batteries when making the connections.
Do not connect the end of the second cable to the negative (-)
terminal of the battery to be jumped. A spark may cause an
explosion of the gases that surround the battery.

WRECKER TOWING
Always unload your vehicle before towing it. The recommended method
of towing is with the drive wheels off the ground.
Before towing, make sure:
²the parking brake is released.
²if air pressure has been lost, to release the brakes manually.
Improper towing of the vehicle will not allow sufficient lubrication of the
transmission which may cause serious damage to internal transmission
components. Always follow the outlined towing procedures.
²To tow a vehicle on the front wheels,the steering wheel must be
in the straight ahead position. Secure the steering wheel with a
holding device (such as provided by a towing company).
²To tow a vehicle on the rear wheels,it will be necessary to remove
the drive axles or disconnect the driveshaft. If the drive axles are
removed, the ends of the axle housing must be sealed to prevent the
loss of axle lubricant during towing.
²To tow a vehicle with an inoperative rear axle,the rear wheels
must be raised onto a dolly or tow the vehicle on the front wheels.
²If your vehicle is equipped with tow hooks,chains must be
fastened directly to the tow hooks on the vehicle.
²If your vehicle is not equipped with tow hooks,chains must be
routed under the bottom edge of the bumper with a protection bar to
protect the bumper, and attached to the vehicle chassis. Under no
circumstances is the vehicle to be lifted or towed by attaching chains
directly to the bumper.
RAISING THE VEHICLE
Never lift the vehicle by the bumper. When raising the vehicle, attach
chains to or place the jack(s) directly beneath the main structural
members of the vehicle.
PUSH-STARTING YOUR VEHICLE
Avoid attempting to start a vehicle by pushing. Instead, use jumper
cables as described underJump starting your vehiclein theRoadside
emergencieschapter. Vehicles with an automatic transmission cannot be
started by pushing.

BRAKE FLUID
Checking and adding brake fluid
Check and refill the Hydromax
brake fluid reservoir using the
following procedure. Refer to the
scheduled maintenance guide for
the service interval.
1. Clean the reservoir caps before
removal to prevent dirt or water
from entering the reservoir.
2. Visually inspect the fluid level.
3. If necessary, add brake fluid from
a clean un-opened container until
the level reaches MAX. Do not fill
above this line.
4. Use only a DOT 3 brake fluid
certified to meet Ford specifications. Refer toLubricant specifications
in theCapacities and specificationschapter.
Brake fluid is toxic. If brake fluid contacts the eyes, flush eyes
with running water for 15 minutes. Seek medical attention if
irritation persists. If taken internally, drink water and induce vomiting.
Seek medical attention immediately.
If you use a brake fluid that is not DOT 3, you will cause
permanent damage to your brakes.
Do not let the reservoir for the master cylinder run dry. This
may cause the brakes to fail.
AVOID MIXING LUBRICANTS
In some cases, different brands of lubricants are not compatible with
each other and deteriorate when mixed. It is best to stick with one brand
during a maintenance interval.

During winter months, it is especially important to wash the vehicle on a
regular basis. Large quantities of dirt and road salt are difficult to
remove and also cause damage to the vehicle.
Any gasoline spilled on the vehicle or deposits such as bird droppings
should be washed and sponged off as soon as possible. Deposits not
removed promptly can cause damage to the vehicle's paintwork.
Remove any exterior accessories, such as antennas, before entering a car
wash. If you have wax applied to the vehicle at a commercial car wash, it
is recommended that you clean the wiper blades and windshield as
described inCleaning the wiper blades and windshield.
After washing, apply the brakes several times to dry them.
Underbody
Flush the complete underside of vehicle frequently. Keep body drain
holes unplugged. Inspect for road damage.
Waxing your vehicle
Waxing your vehicle on a regular basis will reduce minor scratches and
paint damage.
Wax when water stops beading on the surface. This could be every three
or four months, depending on operating conditions.
Use only carnauba or synthetic-based waxes. Use a cleaning fluid with a
clean cloth to remove any bugs before waxing your vehicle. Use tar
remover to remove any tar spots.
Avoid getting wax on the windshield, or on any surfaces which appear
coarse or bumpy. If you have wax applied at a commercial car wash, it is
recommended that you clean the wiper blades and windshield as
described inCleaning the wiper blades and windshield.
Repairing paint chips
Minor scratches or paint damage from road debris may be repaired with the
Ultra Touch Prep and Finishing Kit (#F7AZ-19K507±BA), Lacquer Touch-up
Paint (#ALBZ-19500±XXXXA), or Exterior Acrylic Spray Lacquer
(#ALAZ-19500±XXXXA) from the Ford Car Care Chemicals line. Please note
that the part numbers (shown as XXXX above) will vary with your vehicle's
specific coloring. Observe the application instructions on the products.
Remove particles such as bird droppings, tree sap, insect remains, tar
spots, road salt and industrial fallout immediately.
