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.
There is a bar graph on the hang tag that 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 59) for
additional information.
The Air Index Information hang tag/label must remain on the mower
until it is sold. Remove the hang tag before operating the mower.
