MAINTENANCE
BEFORE PERFORMING MAINTENANCE ON THE INVERTER, REVIEW THE
SAFETY SECTION STARTING ON PAGE 5, AS WELL AS THE FOLLOWING
SAFETY MESSAGES.
Avoid accidentally starting the inverter
during maintenance by removing the
spark plug boot from the spark plug. For
electric start inverters, also disconnect
the battery cables from the battery
(disconnect the black negative (-) cable
first) and place the cables away from
the battery posts to avoid arcing.
Allow hot components to cool to
the touch prior to performing any
maintenance procedure.
Internal pressure can build in the engine
crankcase while the engine is running.
Removing the oil fill plug/ dipstick while
the engine is hot can cause extremely
hot oil to spray out of the crankcase and
can severely burn skin. Allow engine
oil to cool for several minutes before
removing the oil fill plug/dipstick.
Always perform maintenance in a well-
ventilated area. Gasoline fuel and fuel
vapors are extremely flammable and
can ignite under certain conditions.
Following the maintenance schedule is important to keep the inverter in good operating condition. The
following is a summary of maintenance items by periodic maintenance intervals.

Periodic maintenance intervals vary depending on
inverter operating conditions. Operating the inverter
under severe conditions, such as sustained high-
load, high-temperature, or unusually wet or dusty
environments, will require more frequent periodic
maintenance. The intervals listed in the maintenance
schedule should be treated only as a general guideline.

Frequent and prolonged contact with
engine oil may cause skin cancer. Take
protective measures and wear protective
clothing and equipment. Wash all exposed
skin with soap and water.

Failure to perform periodic maintenance
or not following maintenance procedures
can cause the inverter to malfunction and
could result in death or serious injury.
