Driving 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, tools for construction and cranes. 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. Depending on the level and duration of auxiliary horsepower draw, vehicle conditions and surrounding environmental conditions and other factors, this can contribute to elevated transmission fluid temperatures and result in accelerated fluid deterioration, fuel vapor over-pressurization, and other concerns. Ford trucks are fully qualified for stationary PTO operation for 10 minutes or less of continuous operation. For stationary PTO operation of extended duration (beyond 10 minutes), diesel engine is recommended. Further consult your aftermarket PTO installer, since the duration of operation limit for the aftermarket PTO may be less than 10 minutes. A more complete description of PTO operation is discussed in the Ford Truck Body Builders Layout Book, found at www.fleet.ford.com/truckbbas. 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 hubs (for trucks) or the bottom of the wheel rims (for cars). 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. 198 2006 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
