VEHICLE USED AS A STATIONARY POWER SOURCE
Auxiliary equipment called power take-off, or PTO, is often added to the
engine or transmission to operate utility equipment. Examples include a
wheel-lift for tow trucks, cranes, tools for construction or tire service,
and pumping fluids. PTO applications draw auxiliary horsepower from
the powertrain, often while the vehicle is stationary. In this condition,
there is limited cooling air flow through the radiator and around the
vehicle that normally occurs when a vehicle is moving. The aftermarket
PTO system installer, having the most knowledge of the final application,
is responsible for determining whether additional chassis heat protection
or powertrain cooling is required, and alerting the user to the safe and
proper operation.
Ford Super Duty Vehicles are approved for use as a stationary (including
split shaft capability) or mobile power source, within limits and operating
guidelines detailed in the Ford Truck Body Builders Layout Book,
found at www.fleet.ford.com/truckbbas, and through the Ford Truck
Body Builders Advisory Service.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly. Never drive through water
that is higher than the bottom of
the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall. Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes. Driving

SNOWPLOWING
Ford recommends that the Super Duty F-Series used for snow removal
include the Snow Plow Package Option.
Installing the snowplow
Weight limits and guidelines for selecting and installing the snowplow can
be found in the Ford Truck Body Builders Layout Book, Snowplow
section, found at www.fleet.ford.com/truckbbas. A typical installation
affects the following:
• Certification to government safety laws such as occupant protection
and airbag deployment, braking, and lighting. Look for an “Alterer’s
Label” on the vehicle from the snowplow installer certifying that the
installation meets all applicable Federal Motor Vehicle Safety
Standards (FMVSS).
• The Total Accessory Reserve Capacity (TARC) is shown on the lower
right side of the vehicle’s Safety Compliance Certification Label. This
applies to Ford-completed vehicles of 10,000 lb. (4,536 kg) GVWR or
less. This is the weight of permanently-attached auxiliary equipment,
such as snowplow frame-mounting hardware, that can be added to the
vehicle and satisfy Ford compliance certification to FMVSS. Exceeding
this weight may require the auxiliary equipment installer additional
safety certification responsibility. The Front Accessory Reserve
Capacity (FARC) is added for customer convenience.
• Rear ballast weight behind the rear axle may be required to prevent
exceeding the FGAWR, and provide front-to-rear weight balance for
proper braking and steering.
• Front wheel toe may require re-adjustment to prevent premature
uneven tire wear. Specifications are found in the Ford Workshop
Manual.
• Headlight aim may require re-adjustment.
• The tire air pressures recommended for general driving are found on
the vehicle’s Safety Certification Label. The maximum cold inflation
pressure for the tire and associated load rating is imprinted on the tire
sidewall. Tire air pressure may require re-adjustment within these
pressure limits to accommodate the additional weight of the snowplow
installation.
• Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your authorized dealer for
additional information.Driving

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Note: If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the indicator light will illuminate when the spare tire is
in use. To restore the full functionality of the monitoring system, all road
wheels equipped with tire pressure monitoring sensors must be mounted
on the vehicle.
If your vehicle is equipped with TPMS, have a flat serviced by an
authorized dealer in order to prevent damage to the TPMS sensors, refer
to Tire pressure monitoring system (TPMS) in the Tires, Wheels and
Loading chapter. Replace the spare tire with a road tire as soon as
possible. During repairing or replacing of the flat tire, have the
authorized dealer inspect the TPMS sensor for damage. Roadside Emergencies
