FEDERAL EMISSION COMPONENT DEFECT WARRANTY and CALIFORNIA EMISSION CONTROL WARRANTY
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.

AIR INDEX
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).
Descriptive Term
Applicable to Emissions Durability Period
Moderate: 50 hours (engine from 0 to 65 cc)
125 hours (engine greater than 65 cc)
Intermediate: 125 hours (engine from 0 to 65 cc)
250 hours (engine greater than 65 cc)
Extended: 300 hours (engine from 0 to 65 cc)
500 hours (engine greater than 65 cc)
Notice: This hang tag must remain on the engine or piece of equipment, and only be removed by the ultimate purchaser
before operation.
