NOTICE
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 hangtag 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 TermApplicable to Emissions Durability Period
Moderate - 50 hours (engine from 0 to 80 cc)
125 hours (engine greater than 80 cc)
Intermediate-125 hours (engine from 0 to 80 cc)
250 hours (engine greater than 80 cc)
Extended-300 hours (engine from 0 to 80 cc)
500 hours (engine greater than 80 cc)
Notice : This hangtag must remain on this engine or piece of equipment, and
only be removed by the ultimate purchaser before operation.
The engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproductive
harm.
WARNING :
NOTICE
To the engines/generators exported to and used in the countries other than the
