Section 4: Maintenance
Maintenance
Regular maintenance will improve performance and
extend engine/equipment life. Generac Power Systems,
Inc. recommends that all maintenance work be per-
formed by an Independent Authorized Service Dealer
(IASD). Regular maintenance, replacement, or repair of
the emissions control devices and systems may be per-
formed 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.
Preparing for Maintenance
Proceed as follows to prepare for maintenance:
1.
If generator is running, allow generator to run and
cool down for one minute with no load.
2.

nect) to OFF (OPEN).

Performing Scheduled Maintenance
It is important to perform maintenance as specified in the
for correct generator operation.
Engine oil and oil filter must be changed after first 25
hours of operation.
Emissions-critical maintenance must be performed as
scheduled in order for emissions warranty to be valid.
Emissions-critical maintenance consists of servicing the
air filter and spark plug(s) in accordance with
Controller will prompt for Schedule A or Schedule B
maintenance to be performed. Schedule A maintenance
consists of oil, oil filter, and battery check. Schedule B
maintenance includes oil, oil filter, battery check, air
cleaner, and spark plug(s).
Since most maintenance alerts occur at the same time
(most have two year intervals), only one will appear on
control panel display at a time. Once first alert is cleared,
the next active alert will be displayed.
