EMISSIONS
The United States Environmental Protection Agency (US EPA) (and California Air Resources Board (CARB), for
engines/equipment certified to California standards) requires that this engine/equipment complies with exhaust and
evaporative emissions standards. Locate the emissions compliance decal on the engine to determine applicable
standards. For emissions warranty information, please reference the included emissions warranty. It is important to
follow the maintenance specifications in the manual to ensure that the engine complies with the applicable emissions
standards for the duration of the product’s life.
MAINTENANCE TASKS
Regular maintenance will improve performance and extend engine/equipment life. Generac Mobile Products LLC
recommends that all maintenance work be performed by an Independent Authorized Service Dealer (IASD). Regular
maintenance, replacement or repair of the emissions control devices and systems may be performed by any repair
shop or person of the owner’s choosing. However, to obtain emissions control warranty service free of charge, the
work must be performed by an IASD. See the emissions warranty.
Daily checks must be performed when the unit is operated continuously for extended periods of time. Daily checks
and routine monthly checks can be performed by an authorized operator.
Normal maintenance service and replacement of parts is the responsibility of the owner and are not considered
defects in materials or workmanship within the terms of the warranty. It is strongly recommended the equipment be
periodically checked by an Independent Authorized Service Dealer.
Daily Walk Around Inspection
