EQUIPMENT
DESCRIPTION
This generator is an engine-driven, revolving field,
alternating current (AC) generator. It was designedto
supply electrical power for operating compatible electrical
lighting, appliances,tools and motor loads. This manual
contains informationfor a generator that operates 120
and/or 240 Volt, single phase,60 Hz devices that require up
to 3,500 watts (3.5 kW) of power that pult up to
29.2 Amps at 120Volts or 14.6Amps at 240 Volts.
_ CAUTION! Do Not exceed the generator's
wattage/amperagecapacity.Add up the rated watts
of all devices you are connecting to generator
receptacles at one time. This total should not be
greater than 3,500 watts. In most casesrated watts
of the electrical device can be found on the device
nameplate. If the device nameplate givesonly volts
and amps, multiply volts times ampsto obtain watts
(volts X amps =watts).
The 3,500 watt generator hasthe following features:
• 120/240Volt, 20Amp locking type receptacle and a
120Volt, 30 Amp locking type receptacle.
• 120Volt, 15 Amp receptacles.
• Low Oit Shutdown: Automatically shuts down the engine
if oit drops below safeoperation level.
• Fourgallon overhead fuel tank with fuelgauge.
• The generator's revolving field is driven at about
3,600 rpm by a Generac Power Systems6.5 h.p.engine.
_ ARNING! Do Not tamper with engine
governed speed. High operating speedsare
dangerousand increase risk of personal injury or
damageto equipment. The generator supplies
correct rated frequency and voltageonly when
running at proper governed speed. Incorrect
frequency and/or voltage can damage some
connected electrical loads. Operating at excessively
low speedsimposes a heavyload. When adequate
engine power is not availableenginelife may be
shortened.
SAFETY RULES
This generator set was designedand manufactured for
specific applications. Do Not attempt to modify the unit
or use it for any application it was not designed for. If you
haveany questions about your generator's application, ask
your dealer/distributor or consult the factory.
The manufacturer could not possibly anticipate every
circumstance that might involvea hazard. For that reason
warnings in the manualand warnings on tags or decals
affixedto 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 unsafeor pose athreat to you and
others.
Read this manual carefully and become familiar
with your generator set. Know its applications, its
limitations and any hazards involved.
_ 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
usedfor 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 abackfeed
of electrical energy.Whenever unit isproviding
backup power, the electric utility must be notified.
_ 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
adequateventilation isavailable.
The EmissionControl System for this generator is
warranted for standards set by the Environmental
Protection Agency. For warranty informationrefer to the
engine owner's manual.

Generac Portable Products 3,500 Watt Generator
• The generator produces a very powerful voltage that can
causeserious injuryor 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, white barefoot or white hands or feet
are wet Death or serious injuryfrom electrocution may
result.
• Use aground fault circuit interrupter (GFCI) in any damp
or highly conductive area (such as metal decking or steel
work).
• Never useworn, bare, frayed or otherwise damaged
electrical cords with the generator. Death, serious injury
and property damagefrom electrical shock mayresutt
• 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. Always allow room for
fuel expansion. If tank is overfllled, fuel can overflow
onto a hot engine and cause a FIRE or an
EXPLOSION.
• Never store agenerator with fuel in the tank where
gasolinevapors 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 anadequateflow 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 sidesof generator, even
while operating unit outdoors, or you could damagethe
unit.
• Never start, or stop the unitwith electrical loads
connected to receptacles with the connected devices
turned ON. Start the engine and let it stabilize before
connecting anyelectrical loads. Disconnect all electrical
loads before shutting down the generator.
• Do Not insertanyobject through cooling slots of the
engine.You could damagethe unit or injureyourself.
• 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
G EN ERATO R
The National ElectricalCode 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 I).
Generally, connecting a No. 12AWG (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 keepthe 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 ifa ground fault condition exists in the generator or
in connected electrical devices. Proper grounding also helps
dissipate static electricity, whichoften builds up in
ungrounded devices.

BEFORE STARTING THE
ENGINE
Add Oil
_ ARNING! Any attempt to crank or start the
engine before it has been properly filled with the
recommended oil may result in an engine failure.
To fill your engine with oil:
• Place generator on a level surface.
• Clean area around oil fill and remove oil fill cap.
• Select the oil's viscosity grade and fill engine with oil
following the instructions given in the engine owner's
manual. Do Not overfil!!
• Install oil fill cap.
NOTE: The generator's revolving field rides on a pre-
lubricated and sealed ball bearing that requires no
additional lubrication for the life of the bearing.
Add Gasoline
_ ANGER! Explosion Hazard! Never fill fuel tank
indoors.Never fillfuel tank when engine isrunning
or hot Do Not light a cigarette or smoke when
filling the fuel tank.
_ WARNING! Do Not overfill the fuel tank.
Always allow room for fuel expansion.
• Use regular UNLEADED gasoline with the Generator
engine.Do Not use premium gasoline.Do Not mix oil
with gasoline.
• Clean areaaround fuel fill cap,remove cap.
• Add unleaded regulargasoline, slowly to fuel tank. Be
careful not to overfill. Allow about I/2" of tank space for
fuel expansion (Figure 3).
_It'_=== _11Ii I_11,_'_IF I_l_l
1/2" Air Space Tank
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 12. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may occur.
