MAINTENANCE
Before performing maintenance
on the inverter, review Safety on
page 7 and 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 wires from the
battery (disconnect the black negative
(-) wire first) and place the wires 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.

Maintenance Schedule
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.
NOTICE
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.
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.
