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 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.

MAINTENANCE SCHEDULE

WARNING

Failure to perform periodic maintenance or not following maintenance procedures can cause the generator to 

malfunction and could result in death or serious injury.

NOTICE

Periodic maintenance intervals vary depending on generator operating conditions. Operating the generator 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.
