TROUBLESHOOTING
POSSIBLE CAUSE
Battery disconnected or 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 gaso-
line, 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 gaso-
line, or refueled with bad gasoline.
Battery disconnected or 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.
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 gasoline being used.
