Owner’s Manual
Danger: This generator is designed for outdoor use only. Do not use this generator inside
any building or enclosure including the generator compartment of a recreational vehicle
(RV). Fire or an explosion may result. No user performed modifications, including venting
of exhaust and/or cooling ventilation, will eliminate the danger. Also, allow at least two feet
of clearance on all sides of the generator even while operating the unit outdoors.
Danger: If this unit is used for backup power in the event of a utility power failure, the following step must be taken: Before connecting the generator to an electrical system, open
the main circuit breaker or main switch serving the system, to isolate the generator
system from the electric utility. Failure to isolate the generator and utility systems may
result in damage to the generator and may also result in injury or death to electric utility
workers, due to a backfeed of electrical energy.
This symbol points out important safety instructions, which, if not followed, could endanger the
personal safety and/or property of yourself and others. Read and follow all instructions in the
manual before attempting to operate this unit.
Model No.10160 (2000 Watt AC Generator) Part No. B1761 (Revision 0 9/2/97)
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
volt, single phase, 60Hz devices that require up to 2000
watts (2.0 kW) of power that pull up to 15 amps at 120
volts.
CAUTION: Do not exceed the generators
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 2000 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 generators 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.
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 correct 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 short engine
life.
SAFETY RULES
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 generators 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 unsafe or 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.
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.
Never handle any kind of electrical cord or device
while standing in water, while barefoot or while hands
or feet are wet. Dangerous electrical shock will result.
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).
Do not use any worn, bare, frayed or otherwise dam-
aged electrical cord sets with the generator. Using any
defective cord set may result in electrical shock or
damage to equipment and/or property.
Operate generator only on level surfaces and where
it will not be exposed to excessive moisture, dirt, dust
or corrosive vapors.

GENERAC
Generac Mega 2500 Extended Life Generator
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.
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 gaso-
line vapors might reach an open flame or spark or pilot
light (as on a furnace, water heater or clothes dryer).
FIRE or an EXPLOSION might result.
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 engine-generator 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.
Allow at least 2 feet of clearance on all sides of gen-
erator, even while operating unit outdoors, or you
could damage the unit.
Never start, or stop, the engine-generator with elec-
trical loads connected to receptacles 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.
Do not insert any object through cooling slots of the
engine-generator. You could damage the unit or injure
yourself.
Never operate generator (a) in rain; (b) in any enclosed
compartment; (c) if engine speed changes; (d) if connected electrical devices overheat; (e) if electrical
output is lost; (f) if engine or generator sparks; (g) if
flame or smoke is observed while unit is running; (h)
if unit vibrates excessively.
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 SCREW
(Figure 1) is provided on the cradle frame.
Generally, connecting a No. 12 AWG (American Wire
Gauge) stranded copper wire to the grounding wing
screw 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 a 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.

BEFORE STARTING THE
ENGINE
Perform the following tasks before trying to start the
generator engine:
ADD OIL TO ENGINE
Note: When adding oil to the engine crankcase in the
future, use only high quality detergent oil rated with API
service classification SF and SG rated SAE 30 weight.
Use no special additives.
DO NOT USE SAE
10W-40.
Select the oils viscosity grade according to your
expected operating temperature.
Although multi-viscosity oils (5W30, 10W30, etc.)
improve starting in cold weather, these multi-viscosity
oils will result in increased oil consumption when used
above 32°F. Check your engine oil level more frequently
to avoid possible damage from running low on oil.
Place Generator on a level surface
Clean area around oil fill and remove oil dipstick.
Wipe dipstick clean.
Pour oil into the oil fill opening until oil reaches FULL
mark on the dipstick. DO NOT OVERFILL.
Install oil dipstick, hand tighten securely.
CAUTION: Any attempt to crank or start the
engine before it has been properly serviced
with the recommended oil results in an engine
failure.
NOTE: The generators revolving field rides on a pre-
lubricated and sealed ball bearing that requires no
additional lubrication for the life of the bearing.

ADD FUEL
DANGER! NEVER fill fuel tank indoors. NEVER
fill fuel tank when engine is running or hot. DO
NOT light a cigarette or smoke when filling the
fuel tank.
Use regular UNLEADED gasoline with the generator
engine. Regular leaded gasoline may also be used if
UNLEADED is not available.
CAUTION: Do not overfill the fuel tank. Always
allow room for fuel expansion.
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. Drain the
gas tank, start the engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel next season.
See Storage Instructions on page 10 for additional
information.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
Clean area around fuel fill cap, remove cap.
Add UNLEADED regular gasoline, slowly, to fuel
tank.
Install fuel cap and wipe up any spilled gasoline.
OPERATING THE GENERATOR
CAUTION! Never start, or stop, the engine generator with electrical loads connected to the
receptacles with the connected devices turned
ON.
STARTING THE ENGINE
Disconnect all electrical loads from the generator.
Move engine CHOKE CONTROL LEVER to RUN
position.
Move ON/OFF SWITCH to ON position.
If engine is warm, close choke only part way or leave
it fully open. A warm engine needs less choking than
a cold engine.
Grasp starter grip and pull slowly until you feel some
resistance. Let rope return slowly. Then pull cord out
with rapid full arm stroke. Let rope return slowly. Do
not let rope snap back against starter.
If engine hunts or falters after starting, apply choke
until engine begins running smoothly. Then return the
choke to the open position. If engine continues to
hunt, you may need to have the carburetor adjusted.
See Engine Owners Manual.

Hz, ac lighting, appliance, tool and motor loads.
DO NOT connect 240 volts to 120 volts outlets.
DO NOT connect any 3-phase loads to panel recep-
tacles.
DO NOT connect any 50 Hz loads to the generator.
DO NOT overload the generator.
Add up rated watts of all lights, tool, appliance and motor
loads you are powering at one time. This total should
NOT be greater than (a) generators rated wattage
capacity, or (b) circuit breaker rating of the receptacle
supplying power. See Dont Overload the Generator on
Page 8.
STOPPING THE ENGINE
Disconnect all electrical loads
Run engine at no-load for about five minutes,
Turn off the engine by moving the On/Off Switch to the
OFF position. See engine manual.
BATTERY SAFETY
DANGER: Storage batteries give off explosive
hydrogen gas while charging. An explosive mixture will remain around battery for a long time
after it has been charged. The slightest spark
can ignite gas and cause an explosion. Such an
explosion can shatter battery and cause blindness or other serious injury.
DANGER: Do Not Permit smoking, open flame,
sparks or any other source of heat around a battery. Do not use a lighter or other flame for
checking battery fluid levels. Wear protective
goggles, rubber apron and rubber gloves when
working around a battery. Battery electrolyte
fluid is an extremely caustic sulfuric acid solution that can cause severe burns. Do not permit
fluid contact with eyes, skin, clothing etc. If
Spill occurs, flush area with clear water immediately.
CHARGING A BATTERY
Your generator has the capability of recharging a discharged 12-volt automotive or utility style storage
battery. Do not use the unit to charge any 6-volt batteries. Do not use the unit to crank an engine having a
discharged battery. 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.
If the battery is equipped with vent caps, make sure
they are installed and are tight.
If necessary, clean battery posts or terminals.
Connect battery charge cable connector plug to panel
receptacle identified by the words 12-VOLT D.C.
(Figure 7).
Connect battery charge cable clamp with red handle
to battery post or terminal indicated by a POSITIVE,
POS or (+).
Connect battery charge cable clamp with black handle
to battery post or terminal indicated by a NEGATIVE,
NEG, or ().
Start engine (see Starting the Engine on Page 6). Let
the engine run while battery recharges.
When battery has charged, shut down engine (see
Stopping the Engine on Page 7).
NOTE: Use an automotive hydrometer to test battery
state of charge and condition. Follow the hydrometer
manufacturers instructions carefully. Generally, a battery is considered to be at 100% state of charge when
specific gravity of its fluid (as measured by hydrometer)
is 1.260.

CORD SETS FOR
RECEPTACLES
This generator is equipped with the following
receptacles:
TWO 120-VOLT, 15 AMP
RECEPTACLES
This pair of receptacles is protected against overload by
a 15-amp push-to-reset circuit breaker. Use each receptacle to operate 120 volt, single phase 60 Hz, AC
electrical loads requiring up to 1800 watts (1.8 kW) at 15
amps of current. Use cord sets that are rated 125 volts
at 15 amps (or greater).
Caution: Although the generator has two 120
volt, 15 amp receptacles rated at 1800 watts
apiece, you cannot connect more than 2000
watts to the generator. Powering loads that
exceed the wattage/amperage capacity of the
generator can damage it.
DONT 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 generators 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 two-and-a-half 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 below 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 engine manual for instructions.
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. Cooling air
slots in the generator must not become clogged with
snow, leaves or any other foreign material.
Check the cleanliness of the generator frequently and
clean when dust, dirt, oil, moisture or other foreign substances are visible on its exterior surface.
NOTE: We DO NOT recommend using 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.
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.

GENERAC
ONE-YEAR LIMITED WARRANTY FOR PORTABLE GENERATORS
GENERAC warrants to the original purchaser that its generator will be free from defects in materials or workmanship for a
period of one year* from the date of original purchase. This warranty, however,does not include the gasoline engine when
furnished or attached. With the exception of the GN-Series engines, this engine is covered solely by the warranty of the
manufacturer of such engine. The GN-Series engines are covered solely by this Generac 1-year warranty. Starting batteries are not warranted by Generac.
*NOTE: Rental units, demonstrators, commercial or prime power applications, such as construction or utility are warranted
for 90 days. Rental units, demonstrators, or commercial applications such as construction or utility which are resold are not
covered under warranty by GENERAC. Any warranty, whether expressed or implied, rests solely with the seller.
During said warranty period, GENERAC will, at its option, repair or replace any part which, upon examination by GENERAC
is found to be defective under normal use and service. Starting batteries are not warranted by GENERAC. All transportation costs under warranty, including return to the factory if necessary, are to be borne by the purchaser and prepaid by him.
This warranty does not include nominal maintenance and service and does not apply to a generator set, or engine, or parts
which have been subjected to improper or unauthorized installation, misuse, negligence, accident, overloading, overspeeding, improper maintenance, repair or storage so as, in GENERAC's judgment, to adversely affect its performance and
reliability.
There is no other express warranty. GENERAC 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 (one year) as specified in the express warranty. Liability for
consequential, incidental, or special damages under any and all warranties is excluded to the extent permitted by law. Some
states do not allow limitations on how long an implied warranty lasts, or the exclusions or limitations 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.
This warranty is effective for all products manufactured after January 1, 1986, and supersedes all prior warranties of GENERAC.
For service, contact your nearest GENERAC authorized warranty service facility, as shown on GENERAC's listing of authorized warranty service facilities. Warranty service can only be performed by a GENERAC authorized service facility. At the
time of requesting warranty service, evidence of original purchase date must be presented.
