10/03/11 16:59:37 31Z07700_008
GENERATOR SAFETY
Electric Shock Hazards
The generator produces enough electric power to cause a serious
shock or electrocution if misused.
Using a generator or electrical appliance in wet conditions, such as
rain or snow, or near a pool or sprinkler system, or when your hands
are wet, could result in electrocution. Keep the generator dry.
If the generator is stored outdoors, unprotected from the weather,
check all of the electrical components on the control panel before
each use. Moisture or ice can cause a malfunction or short circuit in
electrical components that could result in electrocution.
Do not connect to a building’s electrical system unless an isolation
switch has been installed by a qualified electrician.
For parallel operation, use only a Honda approved parallel operation
cable kit (optional equipment) when connecting one EU2000i
Companion to either an EU2000i or another EU2000i Companion
generator.
Never connect different generator models.
Fire and Burn Hazards
The exhaust system gets hot enough to ignite some materials.
−Keep the generator at least 3 feet (1 meter) away from buildings
and other equipment during operation.
−Do not enclose the generator in any structure.
−Keep flammable materials away from the generator.
The muffler becomes very hot during operation and remains hot for
a while after stopping the engine. Be careful not to touch the muffler
while it is hot. Let the engine cool before storing the generator
indoors.

GENERATOR SAFETY
Refuel With Care
Gasoline is extremely flammable, and gasoline vapor can explode.
Allow the engine to cool if the generator has been in operation. Refuel
only outdoors in a well-ventilated area with the engine off. Do not
overfill the fuel tank. Never smoke near gasoline, and keep other
flames and sparks away. Always store gasoline in an approved
container. Make sure that any spilled fuel has been wiped up before
starting the engine.

BEFORE OPERATION
ARE YOU READY TO GET STARTED?
Your safety is your responsibility. A little time spent in preparation will
significantly reduce your risk of injury.
Knowledge
Read and understand this manual. Know what the controls do and
how to operate them.
Familiarize yourself with the generator and its operation before you
begin using it. Know how to quickly shut off the generator in case of
an emergency.
If the generator is being used to power appliances, be sure that they
do not exceed the generator’s load rating (see pages 29 and 32 ).
IS YOUR GENERATOR READY TO GO?
For your safety, and to maximize the service life of your equipment, it
is very important to take a few moments before you operate the
generator to check its condition. Be sure to take care of any problem
you find, or have your servicing dealer correct it, before you operate
the generator.
Improperly maintaining this
generator, or failing to correct a
problem before operation, could
cause a malfunction in which you
could be seriously injured.
Always perform a pre-operation
inspection before each operation,
and correct any problem.
20
10/03/11 17:01:09 31Z07700_022
BEFORE OPERATION
To prevent a possible fire, keep the generator at least 3 feet (1 meter)
away from building walls and other equipment during operation. Do
not place flammable objects close to the engine.
Before beginning your pre-operation checks, be sure the generator is
on a level surface and the engine switch is in the OFF position.
Check the Engine
Check the oil level (see page 43 ). A low oil level will cause the Oil Alert
system to shut down the engine.
Check the air filter (see page 47 ). A dirty air filter will restrict air flow to
the carburetor, reducing engine and generator performance.
Check the fuel level (see page 40 ). Starting with a full tank will help to
eliminate or reduce operating interruptions for refueling.

10/03/11 17:01:17 31Z07700_023
OPERATION
SAFE OPERATING PRECAUTIONS
Before operating the generator for the first time, review chapters
GENERATOR SAFETY (see page 6 ) and BEFORE OPERATION (see
page 20 ).
For your safety, do not operate the generator in an enclosed area such
as a garage. Your generator’s exhaust contains poisonous carbon
monoxide gas that can collect rapidly in an enclosed area and cause
illness or death.
Exhaust contains poisonous carbon
monoxide gas that can build up to
dangerous levels in closed areas.
Breathing carbon monoxide can
cause unconsciousness or death.
Never run the generator in a closed,
or even partly closed area where
people may be present.
Before connecting an AC appliance or power cord to the generator:
Use grounded 3-prong extension cords, tools, and appliances, or
double-insulated tools and appliances.
Inspect cords and plugs, and replace if damaged.
Make sure that the appliance is in good working order. Faulty
appliances or power cords can create a potential for electric shock.
Make sure the electrical rating of the tool or appliance does not
exceed that of the generator. Never exceed the maximum power
rating of the generator. Power levels between rated and maximum
may be used for no more than 30 minutes.
Operate the generator at least 3 feet (1 meter) away from buildings
and other equipment.
Do not operate the generator in an enclosed structure.

Both types of EU2000i generators (Standard and Companion) can be
connected to each other to increase the available power using a
parallel cable kit (optional equipment, see page 71 ).
Follow the instructions included with the parallel operation cable kit.
Before connecting an appliance or power cord to the generator:
Make sure that it is in good working order. A faulty appliance or
power cord can create a potential for electrical shock.
If an appliance begins to operate abnormally, becomes sluggish, or
stops suddenly, turn it off immediately. Disconnect the appliance,
and determine whether the problem is the appliance or the rated
load capacity of the generator has been exceeded.
Make sure that the combined electrical rating of the tools or
appliances do not exceed that of the generator. Never exceed the
maximum power rating of the generator. Power levels between
rated and maximum may be used for no more than 30 minutes.
Never connect different generator models.
For parallel operation, use only a Honda approved parallel operation
cable kit (optional equipment, see page 71 ) when connecting one
EU2000i Companion to either an EU2000i or another EU2000i
Companion generator.
Never connect or remove the parallel operation cable when the
generator is running.
For single generator operation, the parallel operation cable must be
removed.
Substantial overloading that continuously lights the overload indicator
(red) may damage the generator. Marginal overloading that
temporarily lights the overload indicator (red) may shorten the service
life of the generator.

OPERATION
Limit operation requiring maximum power to 30 minutes.
Maximum power in parallel operation is:
4.0 kVA
For continuous operation, do not exceed the rated power.
Rated power in parallel operation is:
3.2 kVA
The total power requirements (VA) of all appliances connected must
be considered. Appliance and power tool manufacturers usually list
rating information near the model number or serial number.

10/03/11 17:02:36 31Z07700_035
OPERATION
ECO-THROTTLETM SYSTEM
With the switch in the ON position, engine speed is automatically
lowered when loads are reduced, turned off, or disconnected. When
appliances are turned on or reconnected, the engine returns to the
proper speed to power the electrical load. In the OFF position, the
Eco-Throttle system does not operate.
Appliances with large start-up power demands may not allow the
engine to reach normal operating rpm when they are connected to the
generator. Turn the Eco-Throttle switch to the OFF position and
connect the appliance to the generator. If the engine still will not reach
normal operating speed, check that the appliance does not exceed the
rated load capacity of the generator.
If high electrical loads are connected simultaneously, turn the
Eco-Throttle switch to the OFF position to reduce voltage changes.
The Eco-Throttle system is not effective for use with appliances or
tools that require only momentary power. If the tool or appliance will
be turned ON and OFF quickly, the Eco-Throttle switch should be in the
OFF position.

OPERATION
STANDBY POWER
Connections to a Building’s Electrical System
Connections for standby power to a building’s electrical system must
be made by a qualified electrician. The connection must isolate the
generator power from utility power, and must comply with all
applicable laws and electrical codes.
Improper connections to a building’s
electrical system can allow current
from the generator to backfeed into
the utility lines.
Such backfeed may electrocute
utility company workers or others
who contact the lines during a
power outage, and the generator
may explode, burn, or cause fires
when utility power is restored.
Consult the utility company or a
qualified electrician prior to making
any power connections.
In some areas, generators are required by law to be registered with
local utility companies. Check local regulations for proper registration
and use procedures.
System Ground
Honda portable generators have a system ground that connects the
generator frame components to the ground terminals in the AC output
receptacles. The system ground is not connected to the AC neutral
wire. If the generator is tested with a receptacle tester, it will not show
the same ground circuit condition as for a home receptacle.

10/03/11 17:02:47 31Z07700_037
OPERATION
Special Requirements
Do not lay the generator on its side when moving, storing, or
operating it. Oil may leak and damage the engine or your property.
There may be Federal or State Occupational Safety and Health
Administration (OSHA) regulations, local codes, or ordinances that
apply to the intended use of the generator. Please consult a qualified
electrician, electrical inspector, or the local agency having jurisdiction.
In some areas, generators are required to be registered with local
utility companies.
If the generator is used at a construction site, there may be
additional regulations that must be observed.

THE IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical, and trouble free
operation. It will also help reduce air pollution.
To help you properly care for your generator, the following pages
include a maintenance schedule, routine inspection procedures, and
simple maintenance procedures using basic hand tools. Other service
tasks that are more difficult or require special tools are best handled
by professionals and are normally performed by a Honda technician or
other qualified mechanic.
The maintenance schedule applies to normal operating conditions. If
you operate your generator under unusual conditions, such as
sustained high-load or high-temperature operation, or use it in dusty
conditions, consult your servicing dealer for recommendations
applicable to your individual needs and use.
Improper maintenance, or failure to
correct a problem before operation,
can cause a malfunction in which
you can be seriously hurt or killed.
Always follow the inspection and
maintenance recommendations and
schedules in this owner’s manual.
Remember that your servicing dealer knows your generator best and
is fully equipped to maintain and repair it.
To ensure the best quality and reliability, use only new, Honda
Genuine parts or their equivalents for repair and replacement.
Maintenance, replacement, or repair of the emission control devices
and systems may be performed by any engine repair establishment or
individual, using parts that are ‘‘certified’’ to EPA standards.

STORAGE
STORAGE PREPARATION
Proper storage preparation is essential for keeping your generator
trouble-free and looking good. The following steps will help to keep
rust and corrosion from impairing your generator’s function and
appearance, and will make the engine easier to start when you use the
generator again.
Cleaning
Wipe the generator with a moist cloth. After the generator has dried,
touch up any damaged paint, and coat other areas that may rust with a
light film of oil.
Fuel
Depending on the region where you operate your equipment, fuel
formulations may deteriorate and oxidize rapidly. Fuel deterioration
and oxidation can occur in as little as 30 days and may cause damage
to the carburetor and/or fuel system. Please check with your servicing
dealer for local storage recommendations.
Gasoline will oxidize and deteriorate in storage. Old gasoline will
cause hard starting, and it leaves gum deposits that clog the fuel
system. If the gasoline in your generator deteriorates during storage,
you may need to have the carburetor and other fuel system
components serviced or replaced.
The length of time that gasoline can be left in your fuel tank and
carburetor without causing functional problems will vary with such
factors as gasoline blend, your storage temperatures, and whether the
fuel tank is partially or completely filled. The air in a partially filled fuel
tank promotes fuel deterioration. Very warm storage temperatures
accelerate fuel deterioration. Fuel deterioration problems may occur
within a few months, or even less if the gasoline was not fresh when
you filled the fuel tank.
The Distributor’s Limited Warranty does not cover fuel system damage or
engine performance problems resulting from neglected storage
preparation.
You can extend fuel storage life by adding a gasoline stabilizer that is
formulated for that purpose, or you can avoid fuel deterioration
problems by draining the carburetor, sediment cup (if applicable) and/
or fuel tank.

STORAGE
STORAGE PRECAUTIONS
If your generator will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline vapor
ignition.
Select a well ventilated storage area away from any appliance that
operates with a flame, such as a furnace, water heater, or clothes dryer.
Also avoid any area with a spark-producing electric motor, or where
power tools are operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
Unless all fuel has been drained from the fuel tank, leave the engine
switch in the OFF position, and the fuel tank cap vent lever in the OFF
position (see page 26 ) to reduce the possibility of leakage.
Place the generator on a level surface. Tilting or laying it on its side
can cause fuel or oil leakage.
With the engine and exhaust system cool, cover the generator to keep
out dust. A hot engine and exhaust system can ignite or melt some
materials.
Do not use sheet plastic as a dust cover. A nonporous cover will trap
moisture around the generator, promoting rust and corrosion.
REMOVAL FROM STORAGE
Check your generator as described in the BEFORE OPERATION chapter
of this manual (see page 20 ).
If the fuel was drained during storage preparation, fill the tank with
fresh gasoline. If you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline. Gasoline oxidizes and
deteriorates over time, causing hard starting.
If the cylinder was coated with oil during storage preparation, the
engine may smoke briefly at startup. This is normal.
59
10/03/11 17:05:30 31Z07700_061
TRANSPORTING
Do not lay the generator on its side when moving, storing, or
operating it. Oil may leak and damage the engine or your property.
If the generator has been used, allow it cool for at least 15 minutes
before loading the generator on the transport vehicle. A hot engine
and exhaust system can burn you and can ignite some material.
To prevent fuel spillage when transporting, the generator should be
secured upright in its normal operating position, with the engine
switch OFF and the fuel tank cap vent lever turned fully
counterclockwise to the OFF position (see page 26 ).
Take care not to drop or strike the generator when transporting. Do not
place heavy objects on the generator.

TECHNICAL & CONSUMER INFORMATION
Carburetor Modification for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be too
rich. Performance will decrease, and fuel consumption will increase. A
very rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that differs from that at which this engine was
certified, for extended periods of time, may increase emissions.
High altitude performance can be improved by specific modifications
to the carburetor. If you always operate your generator at altitudes
above 5,000 feet (1,500 meters), have your authorized Honda servicing
dealer perform this carburetor modification. This engine, when
operated at high altitude with the carburetor modifications for high
altitude use, will meet each emission standard throughout its useful
life.
Even with carburetor modification, engine horsepower will decrease
about 3.5% for each 1,000-foot (300-meter) increase in altitude. The
effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
When the carburetor has been modified for high altitude operation,
the air/fuel mixture will be too lean for low altitude use. Operation at
altitudes below 5,000 feet (1,500 meters) with a modified carburetor
may cause the engine to overheat and result in serious engine damage.
For use at low altitudes, have your servicing dealer return the
carburetor to original factory specifications.

TECHNICAL & CONSUMER INFORMATION
Emission Control System Information
Source of Emissions
The combustion process produces carbon monoxide, oxides of
nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of
nitrogen is very important because, under certain conditions, they
react to form photochemical smog when subjected to sunlight. Carbon
monoxide does not react in the same way, but it is toxic.
Honda utilizes appropriate air/fuel ratios and other emissions control
systems to reduce the emissions of carbon monoxide, oxides of
nitrogen, and hydrocarbons.
Additionally, Honda fuel systems utilize components and control
technologies to reduce evaporative emissions.
The U.S. and California Clean Air Acts
EPA and California regulations require all manufacturers to furnish
written instructions describing the operation and maintenance of
emission control systems.
The following instructions and procedures must be followed in order
to keep the Honda engine emissions within the emission standards.
Tampering and Altering
Tampering with or altering the emission control system may increase
emissions beyond the legal limit. Among those acts that constitute
tampering are:
Removal or alteration of any part of intake, fuel, or exhaust systems.
Altering or defeating the governor linkage or speed-adjusting
mechanism to cause the engine to operate outside its design
parameters.

TECHNICAL & CONSUMER INFORMATION
Problems That May Affect Emissions
If you are aware of any of the following symptoms, have your engine
inspected and repaired by your authorized Honda servicing dealer.
Hard starting or stalling after starting.
Rough idle.
Misfiring or backfiring under load.
Afterburning (backfiring).
Black exhaust smoke or high fuel consumption.
Replacement Parts
The emission control systems on your new Honda engine were
designed, built, and certified to conform with applicable emission
regulations. We recommend the use of Honda Genuine parts
whenever you have maintenance done. These original-design
replacement parts are manufactured to the same standards as the
original parts, so you can be confident of their performance. The use
of replacement parts that are not of the original design and quality
may impair the effectiveness of your emission control system.
A manufacturer of an aftermarket part assumes the responsibility that
the part will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that use of the part
will not result in a failure of the engine to comply with emission
regulations.
Maintenance
Follow the MAINTENANCE SCHEDULE on page 39 . Remember that
this schedule is based on the assumption that your machine will be
used for its designed purpose. Sustained high-load or hightemperature operation, or use in dusty conditions, will require more
frequent service.
