circumstances, the trajectory may deviate from the suspected path.

LUBRICATION AND MAINTENANCE INTERVALS

New vehicles are lubricated at the factory. After the vehicle is placed in
operation, regular lubrication intervals, based on the type of service and
road conditions, should be established. Thorough lubrication at the
specified intervals will ensure outstanding life cycle value and will reduce
overall expense.

The lubrication intervals specified should be performed at whatever
interval occurs first, whether it is months, miles (kilometers) or hours of
engine operation. Only lubricants of superior quality, such as Motorcraft
lubricants, should be used. The use of inferior products will reduce the
service life of the vehicle or result in failure of its components.

Unless otherwise specified, never add lubricant unless it is the same
grade as that which is already being used. If the grade is not known or
not available, drain, flush and refill with new lubricant.

The interval between lubrication periods, oil changes, etc. depends
entirely upon operating conditions. The loads carried, speeds, road and
weather conditions all contribute to the frequency of lubrication periods.

In some types of operation, and where operating conditions are
extremely severe (such as in deep water, mud or unusually dusty
conditions), the vehicle may require lubrication after every 24 hours of
operation.
