or enclosure including the generator compartment of a recreational vehicle (RV). Carbon monoxide
poisoning, fire and/or an explosion may result. No user performed modifications, including venting of
exhaust and/or cooling ventilation, will eliminate the danger, Always have at least two feet of clearance on
all sides of the generator even while operating the unit outdoors.
DANGER[ You must isolate the generator from the electric utility by opening the electrical system's
main circuit breaker or main switch if this unit is used for backup power, Failure to isolate the generator
from the power utility may result in injury or death to electric utility workers and damage to the
generator due to a backfeed of electrical energy

EQUIPMENT DESCRIPTION
This generator is an engine-driven, revolving field,
alternating current (AC) generator. It was designed to
supply electrical power for operating compatible
electrical lighting, appliance, tool and motor loads.
This manual contains information for a generator that
operates 120 and/or 240 Volt, single phase, 60Hz
devices that require up to 10,000 watts (10.0 kW) of
power that pull up to 83.3 Amps at 120 Volts or
41.6 Amps at 240 Volts.
,_ CAUTION! Do not exceed the generator's
Every effort has been expended to make sure that the
information in this manual is both accurate and
current. However, Generac reserves the right to
change, alter or otherwise improve the product at any
time without prior notice.
wattage/amperage capacity. Add up the rated
watts of all devices you are connecting to
generator receptacles at one time. This total
should not be greater than 10,000 watts for this
generator. See "Don't Overload the Generato¢'
on page 11.
SAFETY RULES
This generator set was designed and manufactured
for specific applications. Do not attempt to modify the
unit or use it for any application it was not designed
for. If you have any questions about your generator's
application, ask your dealer or consult the factory.
The manufacturer could not possibly anticipate every
circumstance that might involve a hazard. For that
reason, warnings in the manual and warnings on tags
or decals affixed to the unit are not all-inclusive. If you
intend to handle, operate or service the unit by a
procedure or method not specifically recommended by
the manufacturer, first make sure that such a
procedure or method will not render this equipment
unsafe or pose a threat to you and others.
Read this manual carefully and become familiar
with your generator set. Know its applications, its
limitations, and any hazards involved.
A
DANGER! Do not tamper with engine
governed speed. High operating speeds are
dangerous and increase the riskof personal
injuryor damage to equipment. The generator
supplies correctly rated frequency and voltage
only when running at proper governed speed.
Incorrect frequency and/or voltage can damage
some connected electrical loads. Operating at
excessively low speeds imposes a heavy load
and, when adequate engine power is not
available, may shorten engine life
/
,_ DANGER! You must isolate the generator
2
from the electric utility by opening the electrical
system's main circuit breaker or main switch if
this unit is used for backup power. Failure to
isolate the generator from the power utility
may result in injury or death to electric
utility workers and damage to the
generator.
,_ DANGER! Generator exhaust gases
contain DEADLY carbon monoxide gas.
Carbon monoxide, if breathed in sufficient
concentrations can cause unconsciousness or
death. Operate this equipment outdoors where
adequate ventilation is available
GeneracPortableProductsSE10000Generator
• The generator produces a very powerful voltage that
can cause serious injury or death by electrocution.
Never touch bare wires or receptacles. Never permit
a child or any unqualified person to operate the
generator.
• Never handle any kind of electrical cord or device
while standing in water, while barefoot or while
hands or feet are wet.
• Use a ground fault circuit interrupter (GFCI) in any
damp or highly conductive area (such as metal
decking or steel work).
• Never use worn, bare, frayed or otherwise damaged
electrical cords with the generator.
• Gasoline is highly FLAMMABLE and its vapors
are EXPLOSIVE. Never allow smoking, open
flames, sparks or heat in the vicinity while
handling gasoline. Avoid spillinggasoline on a hot
engine. Comply with all laws regulating storage and
handling of gasoline.
• Do not overfill the fuel tank. Allow room for fuel
expansion. If tank is overfilled, fuel can overflow
onto a hot engine and cause a FIRE or an
EXPLOSION.
• Never store a generator with fuel in the tank where
gasoline vapors might reach an open flame, spark
or pilot light (as on a furnace, water heater, clothes
dryer) FIRE or an EXPLOSION may result
• Do not insert any object through cooling slots of the
engine You could damage the unit or injure
yourself
• The unit requires an adequate flow of cooling air for
its continued proper operation Never operate the
unit inside any room or enclosure where the free
flow of cooling air into and out of the unit might be
obstructed. Allow at least 3 feet of clearance on
all sides of generator or you could damage the unit.
• Never operate the generator:
in rain; in any enclosed compartment; if connected
electrical devices overheat; if electrical output is
lost; if engine or generator sparks; if flame or smoke
is observed while unit is running; if unit vibrates
excessively.
GROUNDING THE
GENERATOR
The National Electric Code requires the frame and
external electrically conductive parts of the generator
be properly connected to approved earth ground.
Local electrical codes may also require proper
grounding of the unit. For this purpose, a grounding
wing nut (Figure 1) is provided on the cradle.
Grounding Wing Nut
Generally, connecting a No 12 AWG (American Wire
Gauge) stranded copper wire to the grounding wing
nut and to an earth-driven copper or brass grounding
rod (electrode) provides adequate protection against
electrical shock. However, local codes may vary
widely. Consult with a local electrician for grounding
requirements in your area. Be sure to keep the ground
wire attached while you connect the electrode.
Properly grounding the generator helps prevent
electrical shock if ground fault conditions exists in the
generator or in connected electrical devices. Proper
grounding also helps dissipate static electricity, which
often builds up in ungrounded devices.

IMPORTANT! Do not overload the generator! Do
not overload individual panel receptacles! These
outlets are protected against overload with push-to-

circuit breaker is exceeded, that breaker opens and
electrical output to that receptacle is lost Read "Don't

If the Engine Will Not Start
Refer to the engine owner's manual.
STOPPING THE ENGINE
• Remove all electrical loads connected to unit's
receptacles. Never start or stop engine with
devices plugged in and turned on.
• Let engine run at no-load for 30 seconds to stabilize
the unit's internal temperatures.
• Turn the key switch to the "Stop" position.
• Close the fuel valve.
STOPPING THE ENGINE
WITH THE FUEL VALVE
This procedure eliminates fuel from the carburetor
Use this method to stop the generator if you plan to
store the generator over a long period. Fuel will clog
the internal passages of carburetor if allowed to
remain for an extended period.
• Unplug all electrical loads connected to the unit's
receptacles. Never start or stop engine with
devices plugged in and turned on.
• Let engine run at no-load for 30 seconds to stabilize
the internal temperatures of engine and generator.
• Close the fuel valve while the engine is running and
wait until the engine stops.
• Set the key switch to the "Stop" position after the
engine quits.
