Air Index
An Air Index Information hang tag/label is applied to engines certified
to an emission durability time period in accordance with the
requirements of the California Air Resources Board.
The bar graph is intended to provide you, our customer, the ability to
compare the emissions performance of available engines. The lower
the Air Index, the less pollution.
The durability description is intended to provide you with information
relating the engine’s emission durability period. The descriptive term
indicates the useful life period for the engine’s emission control
system. See your EMISSION CONTROL SYSTEM WARRANTY
(page 14) for additional information.
The Air Index Information hang tag/label must remain on the engine
until it is sold. Remove the hang tag before operating the engine.

installed in the final machine will vary depending on numerous factors,
including the operating speed of the engine in application, environmental
conditions, maintenance, and other variables.
