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 AC, single phase, 60Hz
devices that require up to 5,000 watts (5.0 kW) of power
that pull up to 41.7 Amps at 120 Volts or 20.8 Amps at
240 Volts.
CAUTION! Do Not exceed the generator’s
wattage/amperage capacity. Add up the rated watts of all
devices you will connect to generator receptacles at one
time. This total should not be greater than 5,000 watts for
this generator. Review “Don’t Overload the Generator” on
page 10.
The generator’s revolving field is driven at about 3600 rpm
by a single-cylinder engine.
Every effort has been made to ensure that information in
this manual is accurate and current. However, Generac
reserves the right to change, alter or otherwise improve
the product and this document at any time without prior
notice.
CAUTION! Do Not tamper with engine
governed speed. High operating speeds are
dangerous and increase the risk of personal injury
or damage to equipment. The unit 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 on the engine, and may shorten engine
life.

others.
Read this manual carefully and become familiar
with your generator set. Know its applications, its
limitations and any hazards involved.
WARNING! 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. Whenever unit is
providing backup power, the electrical utility must be
notified.
DANGER! Generator exhaust gases contain
DEADLY carbon monoxide gas. Carbon
monoxide, if breathed in sufficient

• 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. Death or serious injury from electrocution may
result.
• 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. Death, serious injury
and property damage from electrical shock may result.
•Gasoline is highly FLAMMABLE and its vapors are
EXPLOSIVE. Never allow smoking, open flames,
sparks or heat in the vicinity while handling
gasoline. Avoid spilling gasoline on a hot engine.
Comply with all laws regulating storage and handling of
gasoline.
•Do Not overfill the fuel tank. Always 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.
• 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 2 feet of clearance on all sides of generator,
even while operating unit outdoors, or you could damage
the unit. See “Cold Weather Operation” on page 8.
•Never start or stop the unit with electrical loads
connected to receptacles with the connected devices
turned ON. Start the engine and let it stabilize before
connecting any electrical loads. Disconnect all electrical
loads before shutting down the generator.
•Do Not insert any object through cooling slots of the
engine. You could damage the unit or injure yourself.
•Never operate the generator:
in rain; in any enclosed compartment; when 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 Electrical Code requires that the frame and
external electrically conductive parts of this generator be
properly connected to an approved earth ground. Local
electrical codes may also require proper grounding of the
unit. For that purpose, a GROUNDING WING NUT is
provided on the generator end (Figure 1).
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. Be careful to keep the grounding wire attached after
connecting the stranded copper wire. However, local codes
may vary widely. Consult with a local electrician for
grounding requirements in your area.
Properly grounding the generator helps prevent electrical
shock if a ground fault condition exists in the generator or
in connected electrical devices. Proper grounding also helps
dissipate static electricity, which often builds up in
ungrounded devices.

• Add unleaded regular gasoline, slowly to fuel tank. Be
careful not to overfill. Allow about 1/2" of tank space for
fuel expansion (Figure 5).
• 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 11. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may occur.

DON’T OVERLOAD THE
GENERATOR
Overloading a generator in excess of its rated wattage
capacity can result in damage to the generator and/or
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 120 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 wattage reference guide (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 a
damaged or defective generator.
Engine Maintenance
See engine manual for instructions.
CAUTION! Avoid prolonged or repeated skin
contact with used motor oil. Used motor oil has
been shown to cause skin cancer in certain
laboratory animals. Thoroughly wash exposed areas
with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.
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. Cooling air
slots in the generator must not become clogged with snow,
leaves or any other foreign material.
Check the 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 engine fuel system and cause problems. In
addition, if water enters generator through cooling air
slots, some of the water will be retained in 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 or soft bristle brush to wipe exterior
surfaces clean.
• 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.
SERVICE/ADJUSTMENTS
Refer to engine owner’s manual for information.
STORAGE
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 cooling air slots and openings on generator
are open and unobstructed.
• Disconnect the negative battery cable from the battery.
CAUTION! Storage covers can be flammable.

NOTES

LIMITED WARRANTY
FOR PORTABLE GENERATORS
(EXCEPT GN ENGINE SERIES)
Generac Portable Products (hereafter referred to as the COMPANY) warrants to the original purchaser that its generator
will be free from defects in materials or workmanship for a period of one year* from the date of original purchase. This
warranty does not apply to units used for prime power in place of utility. This warranty does not include the gasoline
engine when furnished or attached because such engine is covered solely by the warranty of the manufacturer of the
engine. Starting batteries are not warranted by the COMPANY.
*NOTE: Rental units, demonstrators, commercial applications, such as construction or income producing, are warranted
for 90 days. Rental units, demonstrators, or commercial applications such as construction or utility which are resold are
not covered under warranty by the COMPANY. Any warranty, whether expressed or implied, rests solely with the seller.
During said warranty period, the COMPANY will, at its option, repair or replace any part which, upon examination by the
COMPANY is found to be defective under normal use and service. All transportation costs under warranty, including
return to the factory if necessary, are to be borne by the purchaser and prepaid by the purchaser. This warranty does not
include nominal maintenance and service and does not apply to a generator set, or parts, which have been subjected to
improper or unauthorized installation, misuse, negligence, accident, overloading, overspeeding, improper maintenance,
repair or storage so as, in the COMPANY's judgment, to adversely affect its performance and reliability.
THERE IS NO OTHER EXPRESS WARRANTY. THE COMPANY HEREBY DISCLAIMS ANY AND ALL
IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO THOSE OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE TO THE EXTENT PERMITTED BY LAW. THE DURATION OF
ANY IMPLIED WARRANTIES WHICH CANNOT BE DISCLAIMED IS LIMITED TO THE TIME PERIOD AS
SPECIFIED IN THE EXPRESS WARRANTY. LIABILITY FOR INCIDENTAL, CONSEQUENTIAL, OR SPECIAL
DAMAGES UNDER ANY AND ALL WARRANTIES IS EXCLUDED TO THE EXTENT PERMITTED BY LAW.
THE COMPANY ALSO DISCLAIMS ANY RESPONSIBILITY FOR INCIDENTAL OR CONSEQUENTIAL
DAMAGES SUCH AS THE LOSS OF TIME OR THE USE OF THE POWER EQUIPMENT, OR ANY
COMMERCIAL LOSS DUE TO THE FAILURE OF THE EQUIPMENT; AND ANY IMPLIED WARRANTIES
ARE LIMITED TO THE DURATION OF THIS WRITTEN WARRANTY.
Some states do not allow limitations on how long an implied warranty lasts, or the exclusions or limitations of incidental
or consequential damages, so the above limitations or exclusions may not apply to you. This warranty gives you specific
legal rights and you may also have other rights, which vary from state to state.
This warranty is effective for all products manufactured after June, 1998, and supersedes all prior warranties of the
COMPANY.
For service, contact your nearest COMPANY authorized warranty service facility or call 1-920-674-3750, extension 2421.
Warranty service can only be performed by a COMPANY authorized service facility. At the time of requesting warranty
service, evidence of original purchase date must be presented.
