USING RECEPTACLE
NOTE: Do not exceed amperage rating of
receptacles. Exceeding rating will trip
receptacle circuit breaker.
Use receptacles properly. Improper use could
damage generator. Use only grounded
extension cords. Power only grounded or
double-insulated items. Do not overload
receptacles. All generators have the
following receptacles (See Figure 15):
• 120V, 15-amp GFCI duplex receptacle
• 120V, 15-amp duplex receptacle
• 120V, 30-amp twist-lock receptacle
• 120/240V, 20 or 30-amp twist-lock
receptacle

HIGH AND LOW TEMPERATURE
OPERATION
Air temperature affects generator output.
Output drops 1% for each 10° tempera-
ture rise above 60° F. Very low tempera-
tures may make the engine hard to start.
See engine owner’s manual for more
information.
GENERAL INFORMATION
This generator is not large enough to
power your entire home. Do not connect
generator to any existing electrical circuits.
Plug items directly into generator recep-
tacles. Do not exceed amperage rating of
receptacles. Only use grounded cords.
Use only in well-
vented areas. Make
sure area has plenty of free-moving,
fresh, outside air. Never run generator
in an enclosed or confined area. Never
run generator inside occupied building.
Engine exhaust contains poisonous
carbon monoxide gas. Overexposure
will cause loss of consciousness and
will lead to death.
Never connect
generator to any
existing electrical circuits. The genera-
tor output will back-feed into the
utility power line. This may electrocute
a power company line repair person.
Also, if generator is powering electri-
cal circuits, the chance of an electrical
fire exists.
NOTE: We supply the engine owner’s
manual with generator. Refer to that
manual for questions concerning engine
operation.
