are applicable to only those engines / generators complied with EPA (Environmental Protection Agency) and CARB
(California Air Resources Board) emission regulations in the U.S.A.
To the engines / generators exported to and used in the countries other than the U.S.A., warranty service shall be
performed by the distributor in each country in accordance with the standard Robin engine / generator warranty policy
as applicable.
To show compliance with California emission regulations, a hang tag has been provided displaying the Air Index level
and durability period of this engine.
The Air Index level defines how clean an engine's exhaust is over a period of time. A bar graph scaled from "0" (most
clean) to "10" (least clean) is used to show an engine's Air Index level. A lower Air Index level represents cleaner
exhaust from an engine.
The period of time (in hours) that the Air Index level is measured is known as the durability period. Depending on the
size of the engine, a selection of time periods can be used to measure the Air Index level (see below).
