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.
