Honda GX240 Owner's Manual page 18

Maintenance
As the power equipment engine owner, you are responsible for
completing all required maintenance listed in your owner's manual.
Honda recommends that you retain all receipts covering
maintenance on your power equipment engine, but Honda cannot
deny warranty coverage solely for the lack of receipts or for your
failure to ensure that all scheduled maintenance has been
completed.
Follow the MAINTENANCE SCHEDULE on page 7.
Remember that this schedule is based on the assumption that your
engine will be used for its designed purpose. Sustained high-load or
high-temperature operation, or use in dusty conditions, will require
more frequent service.
Air Index
(Models certified for sale in California)
An Air Index Information 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.

The power rating of the engine indicated in this document is the
net power output tested on a production engine for the engine
model and measured in accordance with SAE J1349 at 3,600
rpm (Net Power) and at 2,500 rpm (Max. Net Torque). Mass
production engines may vary from this value.
Actual power output for the engine installed in the final machine
will vary depending on numerous factors, including the operating
speed of the engine in application, environmental conditions,
maintenance, and other variables.
