TROUBLESHOOTING

POSSIBLE CAUSE
Battery not charged.
Check engine indicator light is on.
Engine switch is OFF.
No fuel.
Stale gasoline or water in gasoline.
Lubricant level is low.
Fuel valve is OFF.
Spark plug faulty, fouled, or improperly
gapped.
Engine stored without treating or draining
gasoline, or refueled with bad gasoline.
Dirty fuel filter.
CO sensor LED is flashing red, indicating a
CO hazard.
CO sensor LED is flashing yellow and/or mak-
ing an audible chirp, indicating a sensor fault.
Water in gasoline.
Weak spark at spark plug.
Dirty air filter.
Check engine indicator light is on.
Engine stored without treating or draining
gasoline, or refueled with bad gasoline.
Battery is not charged.
Engine battery charge circuit fuse is blown.
CO sensor has caused automatic shutoff and
CO levels are not yet at a safe level.
Circuit breaker is tripped.
GFCI is tripped.
Item plugged in is defective.
An occasional light "knocking" or "pinging"
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 gaso-
line being used.
