EQUIPMENT

DESCRIPTION

This generator isan 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 information for a generator that operates

120and/or 240 Volt, singlephase,60 Hz devicesthat

require up to 7,500 watts (7.5 kW) of power that draw up

to 62.5 Amps at 120Volts or 31.2 Amps at 240 Volts.

_ CAUTION! Do Not exceed the generator's

wattage/amperagecapacity.Add up the rated watts

of all devicesyou are connecting to generator

receptaclesat one time. This total should not be

greater than 7,500 watts. See "Don't Overload The

Generator" on page 12.

The 7,500EXL generator hasthe following features:

•120/240Volt, 30 Amp locking receptacle, a 120Volt,

30 Amp locking receptacle, a 120Volt, 20 Amp

receptacle, and a 120/240Volt, 50 Amp receptacle.

• Low Oil Shutdown: Automatically shuts down the engine

if oil drops below safe operating pressure.

• Sevengallon overhead fuel tank with fuel gauge.

• The generator's revolving field isdriven at about

3600 rpm by a Generac Power Systems 15 HP electric

start engine.

_ANGER! Do Not tamper with enginegoverned

speed. High operating speeds are dangerousand

increase risk of personal injury or damageto

equipment. The generator supplies correct rated

frequency and voltage only when running at proper

governed speed. Incorrect frequency and/or voltage

candamagesome connected electrical loads.

Operating at excessivelylow speedsimposes a heavy

load. When adequate enginepower isnot available,

engine life may be shortened.

SAFETY RULES

This generator set was designed and manufactured for

specific applications. Do Not attempt to modify the unit

or useit for anyapplication it was not designed for. If you

haveanyquestions about your generator's application, ask

your dealer/distributor 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 unsafeor 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.

_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. Whenever unit is providing

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 is available.

causeserious injury or death by electrocution. Never

touch bare wires or receptacles. Never permit a child

or anyunqualified 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 aground fault circuit interrupter (GFCI) in anydamp

or highly conductive area (such as metal deckingor steel

work).

• Never useworn, bare, frayed or otherwise damaged

electrical cords with the generator. Death, serious injury

and property damagefrom 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 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 a generator 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 an adequateflow of cooling air for its

continued proper operation. Never operate the unit

insideanyroom or enclosure where the free flow of

cooling air into and out of the unit might be obstructed.

Allow at least2 feet of clearanceon all sides of generator,

evenwhile operating unit outdoors, or you could damage

the unit See"Cold Weather Operation" on page 10.

•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 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 enclosedcompartment;when connected

electricaldevicesoverheat; if electrical output islost;if

engine or generator sparks; ifflame or smoke is

observed while unit isrunning; if unit vibrates

excessively.

GROUNDING THE

G EN ERATO R

The National ElectricCode requires the frame and

external electrically conductiveparts 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 ground lug (Figure I) is provided

on the cradle.

Generally, connecting a No. 12AWG (American Wire

Gauge) stranded copper wire to the ground lug screw and

to an earth-driven copper or brassgrounding 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 ifground 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.

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 fillfuel 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 area around fuel fill cap, remove cap.

• Add unleaded regular gasoline, slowly to fuel tank. Be

careful not to overfill. Allow about I/2" of tank space for

fuel expansion (Figure 6).

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 13. Never use engine or carburetor cleaner

products in the fuel tank or permanent damage may occur.
