EQUIPMENT DESCRIPTION
SAFETY RULES
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 Volts, single phase, 60Hz
devices that require up to 7500 watts (7.5 kW) of
power that pull up to 62.5 Amps at 120 Volts or
31.2 Amps at 240 Volts.
This generator set was designed and manufactured
for specific applications. Do Not attempt to modify the
unit or use it for any application it was not designed
for. If you have any questions about your generator’s
application, ask your dealer 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
unsafe or pose a threat to you and others.
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 7,500 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).
Read this manual carefully and become familiar
with your generator set. Know its applications, its
limitations and any hazards involved.
WARNING:
The engine exhaust from this product
contains chemicals known to the State
of California to cause cancer, birth
defects, or other reproductive harm.
The generator’s revolving field is driven at about
3600 rpm by a single 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.
• The generator produces a very powerful voltage that
can cause extremely dangerous electrical shock.
Avoid contact with bare wires, terminals, etc. Never
permit any unqualified person to operate or service
the generator.
DANGER: Do Not tamper with engine
governed speed. High operating speeds are
dangerous and increase risk of personal injury
or 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
at such reduced speeds, when adequate
engine power is not available, and may shorten
engine life.
• Never handle any kind of electrical cord or device
while standing in water, while barefoot or while
hands or feet are wet.
• The National Electric Code requires the frame and
external electrically conductive parts of generator be
properly connected to an approved earth ground.
Local electrical codes may also require proper
grounding of the generator. Consult with a local
electrician for grounding requirements in your area.
• Use a ground fault circuit interrupter in any damp or
highly conductive area (such as metal decking or
steel work).
2
Generac Portable Products 7500EXL Extended Life Generator
• Do Not use worn, bare, frayed or otherwise
damaged electrical cord sets with the generator.
• Never operate generator:
in rain; in any enclosed compartment; if engine
speed changes; 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.
• Operate generator only on level surfaces and where
it will not be exposed to excessive moisture, dirt,
dust or corrosive vapors.
• Gasoline is highly FLAMMABLE and its vapors are
EXPLOSIVE. Do Not permit smoking, open flames,
sparks or heat in the vicinity while handling gasoline.
Avoid spilling gasoline on a hot engine. Comply with
all regulations requiring storage and handling of
gasoline.
GROUNDING THE
GENERATOR
The National Electric Code requires the frame and
external electrically conductive parts of generator be
properly connected to approved earth ground. Local
electrical codes may also require proper grounding of
the unit. For that purpose, a GROUNDING WING NUT
(Figure 1) is provided on the cradle frame.
• 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 FIRE or an
EXPLOSION.
• Never store generator with fuel in tank where
gasoline vapors might reach an open flame, spark or
pilot light (as on a furnace, water heater or clothes
dryer). FIRE or an EXPLOSION might result.
Figure 1 — Grounding Wing Nut
• Generator exhaust gases contain DEADLY carbon
monoxide gas. This dangerous gas, if breathed in
sufficient concentrations, can cause
unconsciousness or even death. Operate this
equipment only in the open air where adequate
ventilation is available.
• 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. Without sufficient cooling air flow, the
unit quickly overheats, damaging the generator or
nearby property.
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
grounding wire secure while you connect to the
grounding rod.
• Allow at least 2 feet of clearance on all sides of
generator, even while operating unit outdoors, or
you could damage the unit. Review Cold Weather
Operation on page 9.
• Never start or stop the unit with electrical loads
connected to receptacles AND with the connected
devices turned ON. Start the engine and let it
stabilize before connecting electrical loads.
Disconnect all electrical loads before shutting down
the generator.
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.

CAUTION: Do Not overfill the fuel tank.
Always allow room for fuel expansion.
Perform the following tasks before trying to start the
generator engine:
Use only regular UNLEADED 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.
Add Engine Oil
NOTE: In the future, When adding oil to the engine
crankcase use only high quality detergent oil rated
with API service classification SF and SG. Use no
special additives. DO NOT USE SAE 10W-40.

Operating Automatic Idle Control
To recharge 12 Volt batteries, proceed as follows:
• Check fluid level in all battery cells. If necessary,
add ONLY distilled water to cover separators in
battery cells. Do Not use tap water.
This switch is designed to greatly improve fuel
economy. When this switch is turned ON, the engine
will only run at its normal high governed engine speed
when an electrical load is connected. When an
electrical load is removed, the engine will run at a
reduced speed. With the switch OFF, the engine will
run at the normal high engine speed. Always have
the switch OFF when starting and stopping the
engine.
• If the battery is equipped with vent caps, make sure
they are installed and are tight.
• If necessary, clean battery terminals.
• Connect battery charge cable connector plug to
panel receptacle identified by the words
“12-VOLTS D.C.”.

10
Generac Portable Products 7500EXL Extended Life Generator
DON’T OVERLOAD THE
GENERATOR
• 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.
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.
• The Wattage Guide shown in Figure 13 is provided
to help you to determine how many items the
generator can operate at one time.

Generac Portable Products 7500EXL Extended Life Generator
GENERAL MAINTENANCE
RECOMMENDATIONS
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.
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.
• Clean the generator as outlined in “To Clean the
Generator.”
• Check that cooling air slots and openings on
generator are open and unobstructed.
Engine Maintenance
See engine manual for instructions.
• Disconnect the negative battery cable from the
battery.
Generator Maintenance
DANGER: Storage covers can be flammable.
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 any foreign material.
Do Not place a storage cover over a hot
generator. Let the unit cool for a sufficient time
before placing the cover on the unit.
Engine Storage
Check the cleanliness of the generator frequently and
clean when dust, dirt, oil, moisture or other foreign
substances are visible on its exterior surface.
See engine owner’s manual for instructions on how to
properly store the engine.
Other Storage Tips
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.
• Do Not store gasoline from one season to the next.
• Replace your gasoline can if it starts to rust. Rust
and/or dirt in a gasoline can cause problems when
you use that fuel with this unit.
• Store unit in clean and dry area.

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

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 need 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.
