No fuel.

Fill fuel tank.

Stale gasoline or water in gasoline.

Drain entire system and refill with fresh fuel.

Lubricant level is low.

Engine is equipped with low oil shutdown. If en-

gine lubricant level is low, it must be filled before 

it will start. Check engine lubricant level and fill, if 

necessary.

Spark plug faulty, fouled, or improperly 

gapped.

Replace spark plug.

Engine stored without treating or 

draining gasoline, or refueled with bad 

gasoline.

Drain fuel and carburetor. Refuel with fresh gas-

oline.

Dirty fuel filter.

Contact a qualified service center.

CO sensor LED is flashing red, indicat

-

ing a CO hazard.

Leave area immediately and relocate to an open 

outdoor area. Ventilate area thoroughly before 

occupying again. Ensure the generator is located 

in an open outdoor area and point exhaust away 

from occupied structures.

CO sensor LED is flashing yellow and/

or making an audible chirp, indicating a 

sensor fault.

The CO sensor needs to be repaired or replaced. 

Contact customer service or a qualified service 

center for assistance.

Engine hard to 

start.

Water in gasoline.

Drain entire system and refill with fresh fuel.

Weak spark at spark plug.

gasoline.

Drain fuel and carburetor. Refuel with fresh gas-

oline.

Dirty air filter.

AC receptacle 

does not work.

Item plugged in is defective.

Try a different item.

Generator is overloaded.

Remove loads and press the reset button.

Circuit breaker is tripped.

Reset the AC circuit breaker.

Generator makes 

a “spark knock” 

or “pinging” 

noise.

An occasional light “knocking” or “ping

-

ing” under heavy load is not a cause 

for concern. However, if the knocking 

or pinging occurs under normal load 

at a steady engine speed, the problem 

may be with the brand of gasoline being 

used.

Switch to a different brand of gasoline, making 

sure that the octane rating is 86 or higher. If 

problem continues, contact a qualified service 

center.

If problem persists after trying the above solutions, contact customer service or a qualified service center for 

assistance.
