MAINTENANCE

Before performing maintenance
on the generator, review Safety on
page 7 and the following safety
messages.
WARNING
Avoid accidentally starting the
generator during maintenance by
removing the spark plug boot from
the spark plug. For electric start
generators, also disconnect the battery
wires from the battery (disconnect the
black negative (-) wire fi rst) 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 fi ll 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
fi ll plug/dipstick.
Always perform maintenance in a well-
ventilated area. Gasoline fuel and fuel
vapors are extremely fl ammable and
can ignite under certain conditions.
