2015 FORD F750 load capacity

FUEL CONSUMPTION
Filling the Tank
The advertised capacity is the indicated capacity and the empty reserve
combined. Indicated capacity is the difference in the amount of fuel in a
full tank and a tank when the fuel gauge indicates empty. Empty reserve
is the amount of fuel in the tank after the fuel gauge indicates empty.
Note:The amount of usable fuel in the empty reserve varies. Do not rely
on it to increase your driving range. When refueling your vehicle after
the fuel gauge indicates empty, you might not be able to refuel the full
amount of the advertised capacity of the fuel tank due to the empty
reserve still present in the tank.
For consistent results when filling the fuel tank:
•Turn the ignition off before fueling. An inaccurate reading results if
you leave the engine running.
•Use the same fill rate (low–medium–high) each time you fill the tank.
•Allow no more than two automatic click–offs when filling.
•Have the vehicle loading and distribution the same every time.
•If your vehicle is equipped with dual fuel tanks, fill the tanks evenly
or the fuel gauge reading may fluctuate slightly until the fuel level
between the two tanks balances out and becomes equal.
Note:If your vehicle is equipped with dual fuel tanks add fuel to both
fuel tanks when refueling or engine performance may degrade.
Results are most accurate when the filling method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the first 1000 miles
(1600 kilometers) of driving; this is your engine’s break-in period. Start
measuring after driving 2000–3000 miles (3200–4800 kilometers). Also,
fuel expense, frequency of fill-ups or fuel gauge readings are not
accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Calculate fuel economy as follows:
•Standard: Divide miles traveled by gallons used.
•Metric: Multiply liters used by 100, then divide by kilometers
traveled.

TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Your vehicle’s load capacity designation is by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Second-unit bodies are not included in maximum trailer weight ratings.
You must subtract the weight of the extra body from the maximum
trailer weight.
Towing a trailer places an extra load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components periodically during, and after, any towing operation.
Load Placement
To help minimize how trailer movement affects your vehicle when
driving:
•Load the heaviest items closest to the trailer floor.
•Load the heaviest items centered between the left and right side
trailer tires.
•Load the heaviest items above the trailer axles or just slightly forward
toward the trailer tongue. Do not allow the final trailer tongue weight
to go above or below 10–15% of the loaded trailer weight.
Towing167

Periodically check:
•Condition of spring leaves for evidence of fatigue, bending or
breakage.
•Condition of suspension mounting brackets and bushings.
•Torque rod mounting fasteners for tightness.
•For proper suspension alignment. Maintain proper alignment at all
times.
•U-bolts. After the chassis has been operating under load for
1000 miles (1600 kilometers) or six months (whichever comes first),
the U-bolt nuts must be re-torqued. Re-torque the U-bolt nuts every
36000 miles (60000 kilometers) thereafter. Clean and lubricate the
U-bolt and nut threads and seats to make sure a like new condition
when re-torqueing.
Note:SeeSpring U-bolt checklater in this chapter.
Supporting Your Vehicle for Service
WARNING:Do not use a jack when working under a vehicle. It
may give way, causing the vehicle to fall and result in property
damage, personal injury or death. Always use floor stands to support
the vehicle.
Prepare your vehicle for service repairs by doing the following:
1. Park your vehicle on a level, concrete floor.
2. Set the parking brake and block the wheels to prevent your vehicle
from moving.
3. Select a jack with a rated capacity sufficient to lift and hold up your
vehicle.
4. Raise your vehicle with the jack applied to the axle(s). Do not use
the bumper as a lifting point.
5. Support your vehicle with floor stands under the axle(s). When
servicing the axle or the suspension, support your vehicle with floor
stands under the frame side-members, preferably between the axles.
Frame and Tow Hooks
Your vehicle’s chassis is manufactured with frame rails of either HSLA
steel or heat-treated steel. Handle each in a specific manner to make
sure maximum service life. Consult the service manual or an authorized
dealer before attempting frame repair or modification.
It is important, particularly on vehicles that use tow hooks frequently, to
inspect the front and rear tow hooks for damage or a loose mounting.
Maintenance207

Proper tire inflation, toe-in adjustment, loads, and road speeds are
important factors governing tire mileage, steering ease and
maneuverability.
Tire Loading
WARNING:Loading tires beyond their rated capacity decreases
tire life requiring more frequent replacement of tires. Overloading
creates an unsafe condition that may result in sudden air loss from a
tire failure resulting in an accident that could cause property damage,
personal injury or death.
Note:Your GAW/GVW rating is correct at the time of your vehicle
production, and reflects the exact rating of the tires specified. When
replacing tires, make sure that the replacement tire load rating (listed in
pounds and kilograms on the tire sidewall) is the same or higher than
the tire that you are replacing. Failure to do so adversely affects
maximum load carrying capacity. Tires with the same size specification
do not always have the same load specification.
Note:The tire installed as original equipment may not be the same as
the tire specified on the DOT label, but has enough load capacity to
carry the GAW/GVW specified.
Note:Tires with the same size specification do not always have the same
load specification.
Matching Tires
Dual Tires:Dual tires should be matched using tires of equivalent size.
Do not mount tires that differ more than one-quarter inch (6
millimeters) in diameter or three-quarters inch (19 millimeters) in
circumference on the same dual wheel assembly.
Mixing:Never mix bias and radial tires on this vehicle. Never mix
different tire sizes or constructions on the same axle.
Rotation:
Rotation is always advisable:
•If there is irregular wear on the front (steering) axle tires, move to
rear position.
•In a dual assembly, reverse the position of the tires if one tire wears
much faster than its mate does.
•On the drive axle, if heel and toe wear or alternate lug wear occurs,
rotating the tires from one end of the axle to the other end of the
axle may help even out this wear.
