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 engine before performing any maintenance. If 

engine must be run, be sure area is well ventilated.

Accidental starting of generator can cause severe injury or 
death. Before performing maintenance, disconnect spark 
plug cap from spark plug.  

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 owner's 
manual.

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.
