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 injuries or property damage can be prevented if you follow all
the 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
A generator's exhaust contains toxic carbon monoxide, which you
cannot see or smell. Breathing carbon monoxide can KILL YOU IN
MINUTES. To avoid carbon monoxide poisoning, follow these
instructions when operating a generator:
• Only run a generator OUTSIDE, far away from windows, doors, and
vents.
• Never operate a generator inside a house, garage, basement, crawl
space, or any enclosed or partially enclosed space.
• Never operate a generator near open doors or windows.
• Get fresh air and seek medical attention immediately if you suspect
you have inhaled carbon monoxide.
Early symptoms of carbon monoxide exposure include headache,
fatigue, shortness of breath, nausea, and dizziness. Continued
exposure to carbon monoxide can cause loss of muscular
coordination, loss of consciousness, and then death.
To alert you to potentially dangerous levels of carbon monoxide
coming from a generator operating outside or from other sources,
install battery operated carbon monoxide alarms or plug-in carbon
monoxide alarms with battery back-up on every level of the home and
outside sleeping areas, according to the manufacturer's instructions.

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.
Do not refuel during operation.
Allow the engine to cool if it has been in operation.
Refuel only outdoors in a well-ventilated area and on a level surface.
Never smoke near gasoline, and keep other flames and sparks away.
Do not overfill the fuel tank.
Make sure that any spilled fuel has been wiped up and cleaned 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 33).
IS YOUR GENERATOR READY TO GO?
For your safety, to ensure compliance with environmental regulations,
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.
20
Failure to properly maintain this
generator, or failing to correct a
problem before operation, could
result in a significant malfunction.
Some malfunctions can seriously
hurt or kill you.
Always perform a pre-operation
inspection before each operation
and correct any problems.
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
• Before each use, look around and underneath the engine for signs of
oil or gasoline leaks.
• Check the engine oil level (see page 42). A low engine oil level will
cause the Oil Alert system to shut down the engine.
• Check the air filters (see page 46). Dirty air filters 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.
21
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 this product's engine 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 the rated power of the generator or the receptacle being
used.
• Operate the generator at least 3 feet (1 meter) away from buildings
and other equipment.
• Do not operate the generator in an enclosed structure.
• Do not place flammable objects close to the engine or locate the
generator near flammable materials.
