EQUIPMENT

DESCRIPTION

This generator isan engine-driven, revolving field, alternating current (AC) generator. It was designed to 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, single phase,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 devices you 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 120/240 Volt, 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 dangerous and 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 is not 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 any application 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.

• The generator produces a very powerful voltage that can 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 a ground fault circuit interrupter (GFCI) in anydamp 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 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 anadequateflow 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 mayalso 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 mayvary 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 fill fuel tank

indoors.Never fillfuel tank whenengine 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 gascan 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.
