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 11) 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.
