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.

A CAUTION] 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.

A

DANGER] 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

a heavy load and, when adequate engine

power is not available, may shorten engine

life

• 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. 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 a damaged 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

• Store the unit in a clean dry place

LIMITED WARRANTY

FOR OVERHEAD VALVE V-TWIN ENGINE-DRIVEN PORTABLE GENERATORS

GENERAC PORTABLE PRODUCTS (hereafter referred to as the COMPANY) warrants to the original purchaser
that all components originally equipped with the generator, excluding the engine, for its portable generator will be

free from defects in materials or workmanship for the items and period set forth below from the date of original
purchase. This warranty is not transferable and applies only to portable generators driven by an overhead valve

V-Twin engine.

Consumer* Commercial*

Alternator 2 years (2nd year parts only) 1 year

Engine Warranted solely by the engine manufacturer

With the exception of European Community Countries, all units bound for export shall be warranted for
One (1) Year in Consumer applications, and 90 days in Commercial applications as defined below.

*NOTE: For the purpose of this warranty "consumer use" means personal residential household use by
original purchaser. This warranty does not apply to units used for Prime Power in place of utility.

"Commercial Use" means all other uses, including rental, construction, commercial and income

producing purposes. Once a generator has experienced commercial use, it shall thereafter be considered

a commercial use generator for the purposes of this warranty.

During said warranty period, the COMPANY will, at is option, repair or replace any part which, upon examination
by the COMPANY, is found to be defective under normal use and service**. Starting batteries are not warranted
by the COMPANY. 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 cover normal maintenance and
service and does not apply to a generator set, alternator, or parts which have been subjected to improper or
unauthorized installation or alteration, misuse, negligence, accident, overloading, overspeeding, improper
maintenance, repair or storage so as, in the COMPANY's judgement, to adversely affect its performance and
reliability.

**NORMAL WEAR: As with all mechanical devices, the generator needs periodic parts service and

replacement to perform well. This warranty will not cover repair when normal use has exhausted the life
of a part or generator.

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
CONSEQUENTIAL, INCIDENTAL OR SPECIAL DAMAGES UNDER ANY AND ALL WARRANTIES
iS EXCLUDED. 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 exclusion or limitation 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.

For service, see your nearest COMPANY authorized warranty service facility or call 1-877-544-0982. Warranty
service can be performed only by a COMPANY authorized service facility_ This warranty will not apply to service
at any other facility. At the time of requesting warranty service, evidence of original purchase date must be
presented.
