MAINTENANCE
BEFORE PERFORMING MAINTENANCE ON THE INVERTER, REVIEW THE SAFETY SECTION
STARTING ON PAGE 5, AS WELL AS THE FOLLOWING SAFETY MESSAGES.
WARNING
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.

CAUTION
Avoid skin contact with engine oil or
gasoline. Prolonged skin contact with
engine oil or gasoline can be harmful.
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.
WARNING
Failure to perform periodic
maintenance or not following maintenance
procedures can cause the inverter to
malfunction and could result in death or
serious injury.
