For proper operation of your generator, make sure that it is placed in an open space. Proper ventilation is vital to its use and your safety. Also keep the generator dry. The generator should be placed on a firm, level surface as well.

Don’t forget to run (exercise) your generator at least once a month. This accomplishes a couple of things. It lubricates the engine by circulating oil, it runs fresh gas through the carburetor and it works to recharge the battery. All of these things help to insure that the generator will start when you really need it in an emergency.

TO OPERATE YOUR GENERATOR:
	Check the fuel level before starting the generator.
	Honda engines are engineered and designed to run on unleaded fuel. Use unleaded gasoline with a pump octane rating of 86 or higher. This will reduce deposit build up on valves, spark arrestor, muffler and spark plugs.
	Never use stale or contaminated gasoline or an oil/gas mixture. Avoid getting dirt or water in the fuel tank.
	Be sure to refuel when the engine is off and in a well-ventilated area. Gasoline is extremely flammable and is explosive under certain conditions. Do not over fill, and make sure that any spilled fuel has been wiped off before starting the generator.
	The fuel tank cap vents the tank, so be sure to store your generator in a well-ventilated area. For example, don’t store the generator below the deck of a boat because gasoline fumes can collect and ignite.
	Check the oil level and air filter.
	Make sure the voltage selector is where it needs to be (120v "only" or 120/240v). If a 240V appliance is connected to the 4-prong receptacle, the switch must be in the "120/240V" position (a series connection). If a 120V appliance ONLY is being connected to any of the 120V 3-prong receptacles, select the "120V ONLY" position (for a parallel connection). The benefit of this is to get maximum power from the 120V 30A locking receptacle.
	Move the generator outside.
	Make sure the system is grounded according to local regulations. See local electrician.
	Connect the transfer switch if powering a house.
	Connect the power cord to the generator.
	Turn the circuit breaker off before starting the generator. Then allow the generator the warm up before turning the circuit breaker on.

TO STOP YOUR GENERATOR:
	To Stop your Generator:
	Turn the circuit breaker off.
	Turn the engine switch off.
	Turn the fuel valve off.

TRANSPORTING AND STORING YOUR GENERATOR

When transporting or storing the generator, be sure to turn the fuel valve OFF. If left on, gasoline may get into the engine crankcase and dilute the engine oil, thus reducing the lubrication properties of the oil and causing severe engine damage.

If you are going to store your generator for more then 2 months, drain the fuel from the carburetor float bowl, drain the fuel from the sediment cup, and then add the correct proportion of fuel conditioner to the tank and top it off.

Honda engines are engineered, designed and certified to run on unleaded fuel. Use unleaded gasoline with a pump octane rating of 89 or higher. Unleaded fuel will reduce deposit build-up on valves, spark arrestor, muffler and spark plug(s).

Never use stale or contaminated gasoline or oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.

Gasoline blended with alcohol or ether is referred to as "oxygenated" fuel. Before using oxygenated fuel, try to confirm the fuel’s contents (refer to the owner’s manual). Some states (provinces of Canada) require the information to be posted on the pump. If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline.

Refuel when the engine is off. Gasoline is extremely flammable and is explosive under certain conditions. Refuel in a well-ventilated area with the engine stopped. Do not over fill. Make sure that any spilled fuel has been wiped off before starting the generator.

The fuel tank cap vents to the atmosphere. Don’t store the generator below the deck of a boat. Gasoline fumes can collect and ignite. Store the generator in a well-ventilated area.

Do not smoke or allow sparks in the area when refueling.

Never refuel while the engine/generator is running. Refuel the generator with the engine stopped and the engine cool.

Wipe up spilled fuel before starting the generator. The engine produces enough heat at the exhaust system, and the generator produces sufficient static electricity, to ignite the fuel vapors.
.

Clean engine oil and clean air are the most critical elements for the survival of the engine. These items should be checked before each use. When the generator is used continuously, these items should checked after each refueling.

The engine oil should be checked for proper quantity and quality. The quantity differs between models. Check oil level following the owner’s manual. The oil quality should be checked for dilution (gas in the oil), dirt (oil is blackened due to dirt getting by the air cleaner) and thickening (oil is breaking down).

The air cleaner should be checked for dirt build-up and maintained according to the appropriate owner’s manual. If the air filter becomes restricted, the carburetor will malfunction and the air cleaner should be serviced or replaced more frequently when the generator is operated in extremely dusty conditions.
.

The voltage selector switches the main power carrying windings of the generator to produce "120V ONLY" or "120/240V". If a 240V appliance is connected to the 4-prong receptacle, the switch must be in the "120/240V" position. If a 120V appliance ONLY is being connected to any of the 120V 3-prong receptacles, select the "120V ONLY" position. The benefit of this is to get maximum power from the 120V 30A locking receptacle.

Switch Position

Honda generators, with 120/240V capabilities, have two separate main windings. Each winding is capable of the same output. The voltage selector switch changes the two main windings from a PARALLEL connection for ("120V ONLY") to a SERIES connection for the "120/240V" position.

In the "120V ONLY" position, the power of the two main windings are connected in parallel (beyond the circuit breakers) and full power can be obtained from the 30A 120V receptacle. When in the "120V ONLY" position, the 240V receptacle cannot be used.

With the voltage selector in the "120/240V" position, the power of each main winding is evenly distributed to all the outlets. It is important that the power connected to the different receptacles be applied equally to avoid overloading any one main winding.
.

The generator has two separate main power producing circuits. These two circuits supply equal power to the receptacles shown when the voltage selector switch is in the "120/240V" position. When two or more receptacles are used; prevent overloading by dividing the loads between the two power circuits.

Example: (EB6500 rated current draw is 50A)

Receptacle 2 has a 15A load connected to it. Receptacle 3 has a 15A load connected to it. Both receptacles are powered by the main power circuit 1. The equation tells us that the total power draw on Circuit 1 is 30A (greater than 25A). This is a substantial overload to this circuit. To eliminate the excess power draw on circuit 1, the load from receptacle "3" should be switched to receptacle "1". Now circuit 1 is powering a 15A load (less than 25A) and circuit 2 is powering a 15A load (less than 25A).

When the voltage selector is in the "120V ONLY" position, do not exceed the rated capacity of any one receptacle. For all receptacles used, do not exceed the rated load capacity of the generator.
.

The auto-throttle system automatically reduces engine speed when all loads are turned off or disconnected. When appliances are turned on or reconnected, the engine returns to the rated speed.

The auto-throttle system will not respond to electrical loads of less than 1 ampere.

The system is not effective for use with appliances that require only momentary power. Leave the auto-throttle OFF if an appliance cycles on and off frequently.

To avoid extended warm-up periods, keep the switch OFF until the engine reaches operating temperature.

Appliances with large start-up power demands may cause the engine to be overloaded and keep it from reaching normal operating rpm. Turn the auto-throttle to the OFF position and connect the appliance to the generator. If the engine is still overloaded and cannot reach normal operating rpm, check that the appliance does not exceed the rated load capacity of the generator.

If the generator is equipped with a pilot light or volt meter and the auto-throttle is ON but no load is connected:

The pilot light will be dimmer.

The voltmeter will display less than the normal output voltage (120V or 240V).
.

In certain applications, Honda industrial generators fall under OSHA regulations. One such regulation is that 120V, 15 and 20 ampere receptacles be protected by Ground Fault Circuit Interrupters (GFCI) automatically open the power circuit in the event there is a current leakage in the tool or appliance plugged into the GFCI receptacle. The GFCI will open the circuit protecting the operator from ground faults. Examples of ground fault current is the current which would flow through a person who is using an appliance with faulty insulation and, at the same time, is in contact with an electrical ground such as a plumbing fixture, wet floor, or earth.

The ground fault circuit interrupter receptacle will not protect against short circuits or overloads. The circuit breaker or circuit protector in the control panel, which supplies power to the circuit, provides that protection.
.

Electric current (amperage) flow is the same in the wires going to and coming from the load. When a ground fault occurs, electric current now has another path and will take this path instead of returning to the source.

Current traveling in wires create magnetic fields around those wires. If the current is the same coming and going, the magnetic fields cancel one another. When there is a ground fault, the returning current has two paths. The returning current through the GFCI is less than the going, there is now a magnetic field difference through the transformer and the control unit will automatically open the circuit.
.

Under normal operations, the GFCI should be tested monthly. There is a test card located on the control panel to record the date of each test. If the generator is stored outdoors, unprotected from the weather, test the GFCI receptacle before each use.

Press the TEST button. The RESET button should extend with a click.

Press the RESET button. The RESET button should be flush with the TEST button.

If either of these tests fail, contact an authorized Honda generator servicing dealer.
.

The EB generators are refreshed and are now called the INDUSTRIAL GENERATORS. All of the industrial generators will be equipped with a GFCI protected 120V duplex receptacle.

The industrial generators are not equipped with GFCI protected 20 ampere 120V locking receptacles. Kits are available which can be installed to GFCI protect the 120V locking receptacles.
.

Bonding the neutral wire to ground is required on some construction sites. Honda’s Industrial Generators provide neutral bonding.

All EB models are neutral bonded which allows the industrial generator to pass OSHA job site inspections.
.

The power tool has a ground wire that connects the tool body to the generator receptacle.

The generator ground terminal is connected to: the frame of the generator, the metal non-current carrying parts of the generator, and the ground terminals of each receptacle.

Before using the ground terminal, consult a qualified electrician, electrical inspector or local agency having jurisdiction for local codes or ordinances that apply.
.

Turn the circuit breaker OFF when starting the generator. The generator starts producing power immediately after the engine starts. If there is a heavy load connected to the generator, it may be strong enough to make the engine hard to start.

If the engine does not start, a heavy load may not allow the engine to reach operating speed. Continuous operation of the generator below normal operating speed may damage the load or the generator.

The circuit breaker should be switched OFF before stopping the engine. The generator will produce power until the engine comes to a complete stop. AVR generators will try to produce steady output as the generator winds down. This may overload the AVR circuits, which could damage the AVR.
.

Turn the fuel valve OFF when transporting or storing the generator. When the generator is being transported, the carburetor inlet needle may unseat allowing fuel to enter the engine crankcase. Gasoline will dilute the engine oil reducing the lubrication properties and cause severe engine damage.
.

The majority of the generator problems occur after the generator is removed from prolonged storage. Gasoline has a very short shelf life. The fuel in the carburetor bowl is vented to the atmosphere. Evaporation of the fuel occurs quicker and will leave the heavier additives and water to plug and corrode the carburetor passages.

If the generator is to be stored for more than 2 months:

Drain the fuel from the carburetor float bowl.

Drain the fuel from the sediment cup.

Add the correct proportion of fuel conditioner to the tank and top it off.

In addition, it is also recommended:

Add a tablespoon of oil through the spark plug hole. Lubricating the valves and piston rings will help prevent corrosion during extended storage periods.

Change the engine oil. Engine oil oxidizes and breaks down like gasoline. Fresh engine oil will ensure the oil will provide proper lubrication when the engine is started after the storage period.
