SAFETY INFORMATION
Honda generators are designed to give safe and dependable service if
operated according to instructions. Read and understand this owner’s manual
before operating your generator. You can help prevent accidents by being
familiar with your generator’s controls, and by observing safe operating
procedures.
Operator Responsibility
l Know how to stop the generator quickly in case of emergency.
l Understand the use of all generator controls, output receptacles, and
connections.
l Be sure that anyone who operates the generator receives proper instruc-
tion. Do not let children operate the generator without parental supervision.
Carbon Monoxide Hazards
l Exhaust contains poisonous carbon monoxide, a colorless and odorless
gas. Breathing exhaust can cause loss of consciousness and may lead to
death.
l If you run the generator in an area that is confined, or even partially
enclosed, the air you breathe could contain a dangerous amount of exhaust
gas. To keep exhaust gas from building up, provide adequate ventilation.
Electric Shock Hazards
l The generator produces enough electric power to cause a serious shock
or electrocution if misused.
l 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.
l If the generator is stored outdoors, unprotected from the weather, check all
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.
l Do not connect to a building’s electrical system unless an isolation switch
has been installed by a qualified electrician.
6
Fire and Burn Hazards
The exhaust system gets hot enough to ignite some materials.
-
Keep the generator at least 1 meter (3 feet) 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.
Gasoline is extremely flammable and is explosive under certain conditions.
Do not smoke or allow flames or sparks where the generator is refueled or
where gasoline is stored. Refuel in a well-ventilated area with the engine
stopped.
Fuel vapors are extremely flammable and may ignite after the engine has
started. Make sure that any spilled fuel has been wiped up before starting
the generator.

GENERATOR USE
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.
m
Improper connections to a building’s electrical system can
allow electrical 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. Consult the utility com-
pany or a qualified electrician.
-1 Improper connections to a building’s electrical system can
allow electrical current from the utility company to backfeed into the
generator. When utility power is restored, the generator may explode,
burn, or cause fires in the building’s electrical system.
Ground System
Honda portable generators have a system ground that connects 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 by 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.
l In some areas, generators are required to be registered with local utility
companies.
l If the generator is used at a construction site, there may be additional
regulations which must be observed.
15
AC Operation
1. Start the engine (refer to page 23) and make sure the pilot lamp comes on.
If not, the filament may be burnt out.
2. Plug in the appliance.
1 NOTICE ( Substantial overloading will switch off the circuit protector.
Marginal overloading may not switch off the circuit protector, but it will
shorten the service life of the generator.
Be sure that all appliances are in good working order before connecting
them to the generator. If an appliance begins to operate abnormally,
becomes sluggish, or stops suddenly, turn off the generator engine
switch immediately. Then disconnect the appliance and examine it for
signs of malfunction.
NOTE: If an overloaded circuit trips the AC circuit protector, reduce the
electrical load on the circuit, and wait a few minutes before resuming
operation.
The green indicator inside the circuit protector button will pop out to show that
the circuit protector has switched off.
Push the button in to reset the circuit protector.

High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be excessively
rich. Performance will decrease, and fuel consumption will increase.
High altitude performance can be improved by installing a smaller diameter
main fuel jet in the carburetor and readjusting the pilot screw. If you always
operate the engine at altitudes higher than 6,000 feet above sea level, have
an authorized Honda generator dealer perform this carburetor modification.
Even with suitable carburetor jetting, engine horsepower will decrease ap-
proximately 3.5%for each 1,000 foot increase in altitude. The effect of altitude
on horsepower will be greater than this if no carburetor modification is made.
-1 If a generator jetted for high altitude is used at a lower
altitude the lean air fuel mixture will reduce performance and may
overheat and seriously damage the engine.
19
PRE-OPERATIOIN CHECK
Engine Oil
-1 Engine oil is a major factor affecting engine performance
and service life. Non-detergent and 2-stroke engine oils will damage the
engine and are not recommended.
Check the oil level BEFORE EACH
USE with the generator on a level surface with the engine stopped.
Use Honda 4-stroke oil, or an equiva-
lent high detergent, premium quality
motor oil certified to meet or exceed
U.S. automobile manufacturer’s re-
quirements for Service Classification
SG, SF/CC, CD.
Motor oils classified SG, SF/CC, CD
will show this designation on the container.

Fuel Recommendation
1. Check the fuel level gauge.
2. Refill the tank if the fuel level is low. Do not fill above the shoulder of the fuel
strainer.
Gasoline is extremely flammable and is explosive under certain
conditions.
Refuel in a well-ventilated area with the engine stopped. Do not
smoke or allow flames or sparks in the area where the engine is
refueled or where gasoline is stored.
Do not overfill the fuel tank (there should be no fuel in the filler neck).
After refueling, make sure the tank cap is closed properly and
securely. Be careful not to spill fuel when refueling. Spilled fuel or fuel
vapor may ignite. If any fuel is spilled, make sure the area is dry before
starting the engine.
Avoid repeated or prolonged contact with skin or breathing of vapor.

Use gasoline with a pump octane rating of 86 or higher
We recommend unleaded gasoline because it produces fewer engine and
spark plug deposits and extends exhaust system life.
Never use stale or contaminated gasoline or oil/gasoline mixture. Avoid
getting dirt or water in the fuel tank.
21
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 an
authorized Honda generator dealer.
[ NOTICE 1 Running the engine with persistent spark knock or pinging
can cause engine damage.
Running the engine with persistent spark knock or pinging is misuse, and the
Distributor’s Limited Warranty does not cover parts damaged by misuse.
22
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 undesirable operating symptoms, try another service station
or switch to another brand or gasoline.
Fuel system damage or performance problems resulting from the use of an
oxygenated fuel containing more than the percentages of oxygenates men-
tioned above are not covered under warranty.
