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
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 and surrounding environmental conditions, and
other factors, this can contribute to elevated transmission fluid
temperatures and resultant 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

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.
