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.
Preparing for Maintenance
1. Set main utility disconnect OFF (OPEN).
2. Lift lid and set MLCB (generator disconnect) on the
generator to OFF (OPEN).
3. Allow generator to run and cool down for one
minute with no load (if running during a utility
outage).
4. Press the OFF mode button on the controller.
5. Remove the 7.5 amp fuse from the control panel.
6. Remove the front panel and intake side panel.
Performing Scheduled
Maintenance
It is important to perform maintenance as specified in the
Service Schedule for proper generator operation.
Engine oil and oil filter must be changed, and valve
clearance adjusted after the first 25 hours of operation.
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
Schedule .
The controller will prompt for Schedule A or Schedule B
maintenance to be performed. Schedule A maintenance
consists of the oil, oil filter, and battery check. Schedule B
maintenance includes the oil, oil filter, battery check, air
cleaner, spark plug(s), and valve clearance.
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 a time. Once the first alert
is cleared, the next active alert will be displayed.
