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 of 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 in accordance with 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 the Ground Fault Circuit Interrupter (GFCI) receptacle and all other 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.
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.
7
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. Always store gasoline in an approved container.

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, 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.
22
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 oil level (see page 48). A low oil level will cause the Oil Alert system to shut down the engine or prevent it from starting.
• Check the air cleaner (see page 51). A dirty air cleaner element will restrict air flow to the carburetor, reducing engine and generator performance.
• Check the fuel level (see page 46). Starting with a full tank will help to eliminate or reduce operating interruptions for refueling.
Check the GFCI
Check the GFCI operation (see page 29) after starting the engine.

OPERATION

AC Applications

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.
Most appliance motors require more than their rated wattage for startup. Make sure the electrical rating of the tool or appliance does not exceed the maximum power rating of the generator.
Maximum power is:
EM4000SX: 4.0 kVA EM5000SX: 5.0 kVA EM6500SX: 6.5 kVA
For continuous operation, do not exceed the rated power. Rated power is:
EM4000SX: 3.6 kVA EM5000SX: 4.5 kVA EM6500SX: 5.5 kVA
In either case, 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.
Substantial overloading will open the AC circuit breaker. Slightly overloading the generator may not switch the AC circuit breaker OFF, but will shorten the service life of the generator.

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, and/or fuel tank.

2. 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.

Battery

Charge the battery before storing the generator (see page 60).
66
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 valve lever in the OFF position (see page 28) 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 a plastic sheet 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 22).
If the generator was stored for 1 year or longer, drain the fuel tank (see page 65) and refuel 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.
67

TRANSPORTING

Do not lay the generator on its side when moving, storing, or operating it. Oil or fuel may leak and damage the engine or your property.
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 lever to the OFF position. Do not use the generator while it is being transported.
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.

TECHNICAL 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.
73
TECHNICAL 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 is a violation of Federal and California law.
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.
74
TECHNICAL 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 45. 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.
75
TECHNICAL INFORMATION
Air Index (Models sold in California)
An Air Index Information label is applied to engines certified to an emission durability time period in accordance with the requirements of the California Air Resources Board.
The bar graph is intended to provide you, our customer, the ability to compare the emissions performance of available engines. The lower the Air Index, the less pollution.
The durability description is intended to provide you with information relating to the engine’s emission durability period.

CONSUMER INFORMATION
Warranty Coverage
Honda power equipment engines sold in the United States and Canada are covered by this warranty for a period of two years from the date of delivery to the original retail purchaser or the length of the Honda Distributor’s Limited Warranty, whichever is longer. This warranty is transferable to each subsequent purchaser for the duration of the warranty period.
If any emission-related part on your engine is defective, the part will be repaired or replaced by Honda without charge for diagnosis, parts, or labor. All defective parts replaced under this warranty become the property of Honda. Only Honda-approved replacement parts may be used in the performance of any warranty repairs and must be provided without charge to the owner. A list of warranted parts is on page 91. Normal maintenance items, such as spark plugs and filters, that are on the warranted parts list are warranted up to their required replacement interval only.
Honda will also replace other engine components damaged by a failure of any warranted part during the warranty period.
The use of replacement parts not equivalent to the original parts may impair the effectiveness of your engine emission control system. If such a replacement part is used in the repair or maintenance of your engine, and an authorized Honda dealer determines it is defective or causes a failure of a warranted part, your claim for repair of your engine may be denied. If the part in question is not related to the reason your engine requires repair, your claim will not be denied.

CONSUMER INFORMATION
To Obtain Warranty Service
You must, at your own expense, take your Honda Power Equipment engine or the product on which it is installed, along with your sales registration card or other proof of original purchase date, to any Honda Power Equipment dealer who is authorized by Honda to sell and service that Honda product during their normal business hours. Claims for repair or adjustment found to be caused solely by defects in material or workmanship will not be denied because the engine was not properly maintained and used. If you are unable to obtain emission warranty service or are dissatisfied with the warranty service you received, contact the owner of the dealership involved. Normally this should resolve your problem. However, if you require further assistance, contact the Honda office in your region:

This warranty does not cover replacement of expendable maintenance items made in connection with required maintenance service after the item’s first scheduled replacement as listed in the maintenance section of the product owner’s manual, such as: spark plugs and filters.

SAFETY

The Importance of Proper Assembly
Proper assembly is essential to operator safety and the reliability of the machine. Any error or oversight made by the person assembling and servicing a unit can easily result in faulty operation, damage to the machine, or injury to the operator.
Improper assembly can cause an unsafe condition.
Failure to properly follow assembly procedures can lead to serious injury or death.
Follow the procedures and precautions in the assembly instructions carefully.
Some of the most important safety precautions are given in the Important Safety Precautions chapter. However, we cannot warn you of every conceivable hazard that can arise in performing this assembly. Only you can decide whether or not you should perform a given task.

ASSEMBLY
Important Safety Precautions
• Make sure you have a clear understanding of all basic shop safety
practices and that you are wearing appropriate clothing and safety equipment. When performing this assembly, be especially careful of the following:
Read the instructions before you begin, and be sure you have
the tools and skills required to perform the tasks safely.
• Make sure the engine is off before you begin any assembly,
maintenance, or repairs. This will help eliminate several potential hazards:
Carbon monoxide poisoning from engine exhaust.
Operate outside away from open windows or doors.
Burns from hot parts.
Let the engine and exhaust system cool before touching.
Injury from moving parts.
Do not run the engine unless the instruction tells you to do so. Even then, keep your hands, fingers, and clothing away. Do not run the engine when any protective guard or shield is removed.
• To reduce the possibility of a fire or explosion, be careful when
working around gasoline or batteries. Use only a non-flammable solvent, not gasoline, to clean parts. Keep all cigarettes, sparks, and flames away from all fuel-related parts.
