GENERATOR SAFETY
IMPORTANT SAFETY INFORMATION
Honda generators are designed for use with electrical equipment that
has suitable power requirements. Other uses can result in injury to the
operator or damage to the generator and other property.
Most accidents can be prevented if you follow all instructions in this
manual and on the generator. The most common hazards are
discussed below, along with the best way to protect yourself and
others.
Operator Responsibility
Know how to stop the generator quickly in case of emergency.
Understand the use of all generator controls, output receptacles,
and connections.
Be sure that anyone who operates the generator receives proper
instruction. Do not let children operate the generator without
parental supervision.
Carbon Monoxide Hazards
Exhaust contains poisonous carbon monoxide, a colorless, odorless
gas. Breathing exhaust can cause loss of consciousness and may
lead to death.
If you run the generator in a confined or even partially enclosed area,
the air you breathe could contain dangerous amounts of exhaust
gas. To keep exhaust gas from building up, provide adequate
ventilation.

05/04/25 09:39:33 31Z11600_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 which could result in electrocution.
Do not connect to a building electrical system unless an isolation
switch has been installed by a qualified electrician.
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.

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 page 34 ).
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 preoperation
inspection before each operation,
and correct any problem.
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 preoperation checks, be sure the generator is
on a level surface and the engine switch is in the OFF position.

OPERATION
SAFE OPERATING PRECAUTIONS
Before operating the generator for the first time, please review the
GENERATOR SAFETY section and the chapter titled BEFORE
OPERATION.
For your safety, avoid starting or operating the generator in an
enclosed area such as a garage. Your generator’s exhaust contains
poisonous carbon monoxide gas which can collect rapidly in an
enclosed area and cause illness or death.
Carbon monoxide gas is toxic.
Breathing it can cause
unconsciousness and even kill you.
Avoid any enclosed areas or
activities that expose you to carbon
monoxide.
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.

OPERATION
AC OPERATION
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 in the appliance, or if the rated load
capacity of the generator has been exceeded.
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.
1. Turn the voltage selector switch to either position.
With the voltage selector switch in the ‘‘120/240V’’ position, you can
use the 120V and 120/240V receptacles simultaneously. If you are
NOT using the 120/240V receptacle, but require more power from
the 120V locking plug receptacle, then select the ‘‘120V ONLY’’
position.

If the generator is overloaded, or if there is a short circuit in a
connected appliance, or if the inverter is overheated, the overload
indicator (red) will come ON. The overload indicator (red) will stay ON,
and after about five seconds, current to the connected appliance(s) will
shut off, and the output indicator (green) will go OFF. Stop the engine
and investigate the problem.
Determine if the cause is a short circuit in a connected appliance, an
overload, or an overheated inverter. Correct the problem and restart
the generator.
Before connecting an appliance to the generator, make sure that it is in
good order and that its electrical rating does not exceed that of the
generator. Then start the generator and connect the appliance power
cord.
When an electric motor is started, the overload indicator (red) may
come on. This is normal if the overload indicator (red) goes off after
about five seconds. If the overload indicator (red) stays on, consult an
authorized Honda generator dealer.

OPERATION
AC Applications
Before connecting an appliance or power cord to the generator:
Make sure that it is in good working order. Faulty appliances or
power cords 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 if the rated
load capacity of the generator has been exceeded.
Make sure that 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.
Substantial overloading will open the circuit breaker. Exceeding the
time limit for maximum power operation or slightly overloading the
generator may not switch the circuit breaker or circuit protector OFF,
but will shorten the service life of the generator.
Limit operation requiring maximum power to 30 minutes.
Maximum power is:
EM5000is: 5,000 VA
EM7000is: 6,500 VA
For continuous operation (longer than 30 minutes), do not exceed the
rated power.
Rated power is:
EM5000is: 4,500 VA
EM7000is: 5,500 VA
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.

OPERATION
AC Receptacle Selection
The generator has separate main power producing circuits. These two
circuits supply power to different receptacles shown when the voltage
selector switch is in the 120/240 V position.
When two or more receptacles are used, prevent overloading by
dividing the load between the two power circuits.
The chart below shows the rated load in amperes that can be
connected to each receptacle to balance the generator when the 120/
240 V locking plug receptacle is used for 120 V.
The total rated ampere draw is:
EM5000is: 37.5 A
EM7000is: 45.8 A

Example: EM5000is
Receptacle 1 has a 15A load connected to it. Receptacle 3 has a 10A
load connected to it. Both receptacles are powered by main power
circuit I. The equation tells us that the total power draw on circuit I is
25A. This is a substantial overload of this circuit. To eliminate the
excess power draw on circuit I, the load from receptacle 3 should be
switched to receptacle 2. Now circuit I is powering the 15A load (less
than 18.8A) and circuit II is powering the 10A load (less than 18.8A).

OPERATION
ECOTHROTTLETM 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
EcoThrottleTM 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 EcoThrottleTM 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
EcoThrottleTM switch to the OFF position to reduce voltage changes.
The EcoThrottleTM system is not effective for use with appliances that
require only momentary power. If the tool or appliance will be turned
ON and OFF quickly, the EcoThrottleTM switch should be in the OFF
position.

OPERATION
STAND BY POWER
Connections to a Building’s Electrical System
Your generator can supply power to a building’s electrical system. If
the generator will be used as an alternative to utility company power,
an isolation switch must be installed to disconnect the utility lines
from the building when the generator is connected. Installation must
be performed by a qualified electrician 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.

Special Requirements
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 which 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, genuine
Honda 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.

MAINTENANCE SAFETY
Some of the most important safety precautions follow. However, we
cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether or not you
should perform a given task.
Failure to properly follow
maintenance instructions and
precautions can cause you to be
seriously hurt or killed.
Always follow the procedures and
precautions in the owner’s manual.
Safety Precautions
Make sure the engine is off before you begin any maintenance or
repairs. This will eliminate several potential hazards:
−Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you operate the
engine.
−Burns from hot parts.
Let the engine and exhaust system cool before touching.
−Injury from moving parts.
Do not run the engine unless instructed to do so.
Read the instructions before you begin, and make sure you have the
tools and skills required.
To reduce the possibility of fire or explosion, be careful when
working around gasoline. Use only a nonflammable solvent, not
gasoline, to clean parts. Keep cigarettes, sparks, and flames away
from all fuel-related parts.

FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating of 86 or higher.
This engine is certified to operate on unleaded gasoline.
Unleaded gasoline produces fewer engine and spark plug deposits
and extends exhaust system life.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Occasionally you may hear light ‘‘spark knock’’ or ‘‘pinging’’ (metallic
rapping noise) while operating under heavy loads. This is no cause for
concern.
If spark knock or pinging occurs at a steady engine speed, under
normal load, change brands of gasoline. If spark knock or pinging
persists, see a Honda servicing dealer.
Running the engine with persistent spark knock or pinging can cause
engine damage.
Running the engine with persistent spark knock or pinging is misuse,

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
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 depending on the gasoline
formulation in your area.
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 fuel tank and carburetor.
59
05/04/25 09:45:51 31Z11600_061
STORAGE
Adding a Gasoline Stabilizer to Extend Fuel Storage Life
When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline.
If only partially filled, air in the tank will promote fuel deterioration
during storage. If you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline.
1. Add fuel stabilizer following manufacturer’s instructions.
2. After adding a fuel stabilizer, run the engine outdoors for 10 minutes
to be sure that treated gasoline has replaced the untreated gasoline
in the carburetor.
3. Stop the engine, and turn the fuel valve lever to the OFF position.

Draining the Fuel Tank and Carburetor
Gasoline is highly flammable and
explosive.
You can be burned or seriously
injured when handling fuel.
Stop the engine and keep heat,
sparks, and flame away.
Handle fuel only outdoors.
Wipe up spills immediately.
DRAIN SCREW
1. Place a suitable gasoline container
below the carburetor drain hose.
2. Loosen the carburetor drain screw
and drain the gasoline from the
carburetor.
3. After all the fuel has drained into the
container, tighten the drain screw
securely.
4. Place an approved gasoline container below the sediment cup, and
use a funnel to avoid spilling fuel.
Remove the sediment cup, then move the fuel valve lever to the ON
position (see page 50 ).
5. Allow the fuel to drain completely, then reinstall the sediment cup
(see page 50 ).

Engine Oil
1. Change the engine oil (see page 46 ).
2. Remove the spark plug (see page 51 ).
3. Pour a tablespoon (5 − 10 cc) of clean engine oil into the cylinder.
4. Pull the starter rope several times to distribute the oil in the cylinder.
5. Reinstall the spark plug.
6. Slowly pull the starter grip until resistance is felt. At this point, the
piston is coming up on its compression stroke and both the intake
and exhaust valves are closed. Storing the engine in this position
will help to protect it from internal corrosion. Return the starter grip
gently.

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 fuel valve
in the OFF position to reduce the possibility of leakage.
Place the generator on a level surface. Tilting 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.
Fully charge the battery. Recharge the battery once a month (see page
57 ).
REMOVAL FROM STORAGE
Check your generator as described in the BEFORE OPERATION chapter
of this manual.
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.
63
05/04/25 09:46:20 31Z11600_065
TRANSPORTING
If the generator has been running, allow the engine to 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
materials.
Keep the generator level when transporting to reduce the possibility of
fuel leakage. Move the fuel valve to the OFF position.
When using ropes or tie-down straps to secure the generator for
transportation, be sure to only use the frame bars as attachment
points. Do not fasten ropes or straps to any portions of the generator
body or the folding transport handle.

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
Oxygenated Fuels
Some conventional gasolines are being blended with alcohol or an
ether compound. These gasolines are collectively referred to as
oxygenated fuels. To meet clean air standards, some areas of the
United States and Canada use oxygenated fuels to help reduce
emissions.
If you use an oxygenated fuel, be sure it is unleaded and meets the
minimum octane rating requirement.
Before using an oxygenated fuel, try to confirm the fuel’s contents.
Some states/provinces require this information to be posted on the
pump.
The following are the EPA approved percentages of oxygenates:
ETHANOL
(ethyl or grain alcohol) 10% by volume
You may use gasoline containing up to 10%
ethanol by volume. Gasoline containing ethanol
may be marketed under the name Gasohol.
MTBE
(Methyl Tertiary Butyl Ether) 15% by volume
You may use gasoline containing up to 15% MTBE
by volume.
METHANOL
(methyl or wood alcohol) 5% by volume
You may use gasoline containing up to 5%
methanol by volume as long as it also contains
cosolvents and corrosion inhibitors to protect the
fuel system. Gasoline containing more than 5%
methanol by volume may cause starting and/or
performance problems. It may also damage metal,
rubber, and plastic parts of your fuel system.
If you notice any undersirable operating symptoms, try another
service station, or switch to another brand of gasoline.
Fuel system damage or performance problems resulting from the use
of an oxygenated fuel containing more than the percentages of
oxygenates mentioned above are not covered under warranty.

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 uses lean carburetor settings and other systems to reduce the
emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.
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.
71

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 EPA and California
emission regulations. We recommend the use of genuine Honda 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 42 . Remember that this
schedule is based on the assumption that your machine will be used
for its designed purpose. Sustained high-load or high-temperature
operation, or use in dusty conditions, will require more frequent
service.
