Lubrication and Fluids
All new vehicles are lubricated at
the factory. Once the vehicle is in
operation, regular lubrication and
maintenance intervals (based on the
type of service and road conditions)
must be established and performed.
Load weight, vehicle speed, road
conditions, and weather conditions
all contribute to lubrication
frequency. Performing thorough
lubrication and maintenance at the
specified intervals will ensure an
outstanding vehicle life and will
reduce overall operating expense.
Only lubricants of superior quality
should be used. The use of inferior
products will reduce the service life
of the vehicle or result in failure of
its components.
