Driving and adversely affect driver and passenger safety. Frequent inspection of vehicle chassis components is recommended if the vehicle is subjected to heavy off-road usage. 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 extended duration stationary PTO operation (beyond 10 minutes), a diesel engine is recommended, and further consult your aftermarket PTO installer. Transmission Power Take-Off (PTO) Provision (if equipped) Some vehicles with an automatic transmission may be equipped with a "Transmission Power Take-Off Provision", Option Code 62R. These vehicles have a special transmission that includes a port on the left-hand side to mount an aftermarket PTO, an internal PTO gear, and calibration for PTO usage. The actual PTO and related equipment is not offered by Ford Motor Company, but is installed by an aftermarket source. The PTO gear in the transmission will drive the aftermarket PTO while driving the vehicle. Therefore, some additional gear noise that may result is normal. Also, the transmission upshift and downshift schedules will be reduced by about 15% and may result in a firmer shift feel during PTO mobile applications. 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).
