Section 4: Maintenance

Maintenance

Regular maintenance will improve performance and
extend engine/equipment life. Generac Power Systems,
Inc. 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. To obtain emissions control warranty service
free of charge, the work must be performed by an IASD.
See the emissions warranty.
WARNING
Performing Scheduled
Maintenance
It is important to perform maintenance as specified in the
Service Schedule for proper generator operation and to
ensure that the generator complies with the applicable
emission standards for the duration of its useful life.
Service and repairs may be performed by any qualified
service person or repair shop.
Engine oil and filter must be changed and valve
clearance adjusted after the first 25 hours of operation.
Additionally, emissions critical maintenance must be
performed as scheduled in order for the Emissions
Warranty to be valid. Emissions-critical maintenance
consists of servicing the air filter and spark plugs in
accordance with the Service
The controller will prompt for Schedule A or Schedule B
maintenance to be performed. Schedule A maintenance
consists of the oil, oil filter, and tune-up. Schedule B
maintenance includes the oil, oil filter, tune-up, air
cleaner, spark plug(s), and valve clearance.
NOTE: Since most maintenance alerts will occur at the
same time (most have two year intervals), only one will
appear on the control panel display at any one time.
Once the first alert is cleared, the next active alert will be
displayed.
