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.

Your vehicle is qualified for use as a stationary power source, within

limits 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.

Gas engine vehicles are qualified for up to 10 minutes of continuous

operation as a stationary power source, due to the potential for the

normal venting of fuel vapors. Further consult your aftermarket PTO

installer, since the duration of operation limit for the aftermarket PTO

may be less than the vehicle is capable of.

DRIVING THROUGH WATER

If driving through deep or standing

water is unavoidable, proceed very

slowly especially when the depth is

not known. 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.
