Maintenance
Maintain the generator according to the maintenance schedule in this section. Service items more frequently
when used in dusty areas, or under conditions of high load, temperature, and humidity.
Air Quality Index (only for California certified models)
CARB requires that an air quality index label be attached to every certified engine showing the engine emission
information for the emission duration period. The label is provided for the user to compare the emission
performance of different engines. The lower the air index, the better the engine emission performance. The
description of durability is helpful for the user to learn the engine emission duration period and the service life of
emission control system. Refer to the
warranty section of this Owner’s Manual for more information.
The air quality index label is designed to be permanently affixed to the generator and removal should not be
attempted.
