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