Maintenance
Follow the maintenance schedule on page . Remember that this
schedule is based on the assumption that your machine will be
used for its designed purpose. Sustained high-load or high-
temperature operation, or use in unusually wet or dusty conditions,
will require more frequent service.
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 to 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 for additional information.
Descriptive Term Applicable to Emissions Durability Period
Moderate 50 hours [0 80 cm (0 80 cc) inclusive]
125 hours [greater than 80 cm (80 cc)]
Intermediate 125 hours [0 80 cm (0 80 cc) inclusive]
250 hours [greater than 80 cm (80 cc)]
Extended 300 hours [0 80 cm (0 80 cc) inclusive]
500 hours [greater than 80 cm (80 cc)]
