7: MAINTENANCE
7.1 CONSUMER MAINTENANCE SCHEDULE
Periodic maintenance and adjustment are necessary to keep the generator in good operating condition. Perform service and 
inspection at intervals shown in the Generator Maintenance Schedule (Table 7-1).
 
Using a generator indoors CAN KILL YOU IN MINUTES.
Generator exhaust contains carbon monoxide. This is a poi-
son you cannot see or smell.
NEVER use inside a home 
or garage, EVEN IF doors 
and windows are open.
Only use OUTSIDE and 
far away from windows, 
doors, and vents.
• Shut off the engine before performing any maintenance. 
If the engine must be run, be sure the area is well venti-
lated.
NOTICE
Maintenance, replacement, or repair of the emission 
control devices and systems may be performed by any 
non-road engine repair establishment or individual.
DANGER
Accidental starting of generator can cause severe injury or 
death. Before performing maintenance, disconnect spark 
plug cap from spark plug. Also disconnect both starting bat-
tery cables. Remove the negative (-) cable first to reduce the 
risk of arcing.
Improper maintenance, or failure to correct a problem before 
operation, can cause a malfunction in which you can be seri-
ously hurt or killed. Always follow inspection and mainte-
nance recommendations and schedules in this manual.
NOTICE
The maintenance schedule applies to normal operating con-
ditions. If you operate generator under severe conditions, 
such as sustained high-load or high-temperature, or use it in 
unusually wet or dusty conditions, consult your servicing 
dealer for recommendations applicable to your individual 
needs and use.
