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, 60 Hz
devices that require up to 9,000 watts (9.0kW) of
power that pull up to 75 Amps at 120 Volts or
37.5 Amps at 240 Volts.
ACAUTION] Do not exceed the generator's
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 9,000 watts for this
generator. In most cases rated watts of the
electrical device can be found on the device
nameplate. If the device nameplate gives only
volts and amps, multiply volts times amps to
obtain watts (volts x amps = watts).
The generator's revolving field is driven at about
3600 rpm by a twin-cylinder engine.
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.
ADANGER] Do not tamper with engine governed speed. High operating speeds are
dangerous and increase the risk of 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
aheavy load and, when adequate engine
power is not available, may shorten engine
life

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. A grounding wing nut (Figure 1)
is provided for this purpose.
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.

1_" AirSpace _nk
• Install fuel cap and wipe up any spilled gasoline
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as
the carburetor, fuel filter, fuel hose or tank during
storage. Also, experience indicates that
alcohol-blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which leads to
separation and formation of acids during storage.
Acidic gas can damage the fuel system of an engine
while in storage. To avoid engine problems, the fuel
system should be emptied before storage of 30 days
or longer. See "Storage" on page 13. Never use
engine or carburetor cleaner products in the fuel tank
or permanent damage may occur.

GeneracPortableProducts9,000WattGenerator
DON'T OVERLOAD THE
GENERATOR
Overloading a generator in excess of its rated wattage
capacity can result in damage to generator and to
connected electrical devices. Observe the following, to
prevent overloading the unit:
• Add up the total wattage of all electrical devices to
be connected at one time. This total should NOT be
greater than the generator's wattage capacity.
• The rated wattage of lights can be taken from light
bulbs The rated wattage of tools, appliances and
motors can usually be found on a data plate or
decal affixed to the device.
• If the appliance, tool or motor does not give
wattage, multiply volts times ampere rating to
determine watts (volts x amps = watts).
• Some electric motors, such as induction types,
require about three times more watts of power for
starting than for running. This surge of power lasts
for only a few seconds when starting such motors.
Be sure you allow for this high starting wattage
when selecting electrical devices to connect to your
generator. First figure the watts needed to start the
largest motor. Add to that figure the running watts of
all other connected loads.
• Items in the guide shown in Figure 13 are provided
to help you to determine how many items the
generator can operate at one time.

GENERAL MAINTENANCE
RECOMMENDATIONS
The Owner/Operator is responsible for making sure
that all periodic maintenance tasks are completed on
a timely basis; that all discrepancies are corrected;
and that the unit is kept clean and properly stored.
Never operate adamaged or defective generator.
Engine Maintenance
See your engine owner's manual for information
needed to maintain and service the engine
Generator Maintenance
Generator maintenance consists of keeping the unit
clean and dry Operate and store the unit in a clean
dry environment where it will not be exposed to
excessive dust, dirt, moisture or any corrosive vapors.
Make sure the cooling air slots in the generator do not
become clogged with snow, leaves or other foreign
material.
Check cleanliness of the generator frequently and
clean when dust, dirt, oil, moisture or other foreign
substances are visible on its exterior surface.
NOTE: DO NOT use a garden hose to clean
generator. Water can enter the engine fuel system
and cause problems. In addition, if water enters the
generator through the cooling air slots, some water
will be retained in the voids and cracks of the rotor
and stator winding insulation. Water and dirt buildup
on the generator internal windings will eventually
decrease the insulation resistance of these windings.
To Clean the Generator
• Use a damp cloth to wipe exterior surfaces clean.
• Soft, bristle brush may be used to loosen caked on
dirt or oil.
• A vacuum cleaner may be used to pick up loose dirt
and debris.
• Low pressure air (not to exceed 25 psi) may be
used to blow away dirt. Inspect cooling air slots and
opening on generator. These openings must be kept
clean and unobstructed.
STORAGE INSTRUCTIONS
The generator should be started at least once every
seven days and allowed to run at least 30 minutes. If
this cannot be done and you must store the unit for
more than 30 days, use the following guidelines to
prepare it for storage.
Generator Storage
• Clean the generator as outlined in "To Clean the
Generator_"
• Check that the cooling air slots and openings on the
generator are open and unobstructed.
• Drain fuel and run engine until the fuel system is
empty.
• Remove spark plugs and pour about 1 ounce of
clean engine oil into spark plug holes. Crank engine
over slowly several times, to distribute oil. Install
and tighten spark plugs.
• Change engine oil and filter, as described in engine
owner's manual.
•Remove the negative battery cable from the battery
to prevent the battery from being depleted
