FUEL VALVE The fuel valve is located between the fuel tank and carburetor. When the valve lever is in the ON position, fuel is allowed to flow from the fuel tank to the carburetor. Be sure to return the fuel valve lever to the OFF position after stopping the engine.
CIRCUIT BREAKER The circuit breaker will automatically switch OFF if there is a short circuit or a significant overload of the generator at the receptacle, or if the ground-fault circuit interrupter (GFCI) detects a ground-fault current. Check the following if the circuit breaker switches OFF automatically: When the GFCI RESET button is extended (page 18): −...
CIRCUIT PROTECTOR The circuit protectors will automatically switch OFF if there is a short circuit or a significant overload of the generator at the 120V 20A, 120V 30A locking plug, or 120/240V 30A locking plug receptacle. If a circuit protector switches OFF automatically, check that the appliance is working properly and does not exceed the rated load capacity of the circuit before resetting the circuit protector to the ON position.
GROUND FAULT CIRCUIT INTERRUPTER (GFCI) Using the generator in rain or snow or near water can lead to death from electric shock. Keep the generator dry. All receptacles on the generator are protected by a ground-fault circuit interrupter (GFCI) for protection against the shock hazard of ground- fault current.
Observe the following precautions to ensure proper GFCI operation and to reduce shock hazards: Use grounded 3-conductor extension cords, tools, and appliances, or double-insulated tools and appliances. Inspect cords and plugs, and replace if damaged. Do not use cord lengths greater than 164 feet (50 meters), and do not use multiple tools and appliances with built-in noise filters.
You risk electric shock if you operate this generator with a faulty GFCI (ground-fault circuit interrupter). Test GFCI before use. If GFCI fails test, do not use your generator. See your Honda dealer. Unplug all tools and appliances from the generator. Start the engine.

Auto Throttle System With the switch in the ON position, engine speed is automatically reduced when all loads are turned off or disconnected. When appliances are turned on or reconnected, the engine returns to rated speed. In the OFF position, the Auto Throttle system does not operate. The Auto Throttle system will not respond to electrical loads of less than 1 ampere.
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.
PRE-OPERATION CHECK Before beginning your pre-operation checks, be sure the generator is on a level surface and the engine switch is in the OFF position. Engine Oil Check the oil level BEFORE EACH USE with the generator on a level surface and the engine stopped.
Refueling With the engine stopped, check the fuel level gauge. Refill the fuel tank if the fuel level is low. 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.
Fuel Recommendations This engine is certified to operate on regular unleaded gasoline with a pump octane rating of 86 or higher. Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt or water in the fuel tank. You may use regular unleaded gasoline containing no more than 10% ethanol (E10) or 5% methanol by volume.
Battery The electrolyte level must be kept between the UPPER and LOWER level marks. UPPER LEVEL LOWER LEVEL If the electrolyte level is near the LOWER level, remove the battery filler caps and carefully add distilled water to the upper level line (see page The battery contains sulfuric acid (electrolyte) which is highly corrosive and poisonous.
STARTING THE ENGINE Starting the Engine 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.
Select the choke knob position. − A cold engine: Pull the choke knob to the CLOSED position. − A warm engine: Leave the choke knob in the OPEN position. If the engine does not start, pull the choke knob to the CLOSED position. Make sure the Auto Throttle switch is in the OFF position, or more time will be required for warm up.

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.
The following instructions and procedures must be followed in order to keep the emissions from your Honda engine within the emission standards. Tampering and Altering Tampering with or altering the emission control system may increase emissions beyond the legal limit.
The emission control systems on your 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.
Replace the paper air filter only. Service more frequently when used in dusty areas. These items should be serviced by your Honda servicing dealer, unless you have the proper tools and are mechanically proficient. Refer to the Honda shop manual for service procedures.
Engine Oil Change Drain the oil while the engine is warm to assure rapid and complete draining. Open the top cover to access the oil filler cap. Remove the oil filler cap and oil drain bolt, and drain the oil into a suitable container.
Clean the filter mounting base, and coat the O-ring of the new oil filter with clean engine oil. Use only a Honda Genuine oil filter or a filter of equivalent quality specified for your model. Using the wrong Honda filter or a non- Honda filter which is not of equivalent quality may cause engine damage.
Air Cleaner Service A dirty air filter will restrict air flow to the carburetor. To prevent carburetor malfunction, service the air cleaner regularly. Service more frequently when operating the generator in extremely dusty areas. Never run the generator without the air filter. Rapid engine wear will result.
Inspect both air filters, and replace them if they are damaged. Always replace the paper air filter at the scheduled interval (see page 40 ). Clean the air filters if they are to be reused. Paper air filter: Tap the paper air filter several times on a hard surface to remove dirt, or blow compressed air ［...
Spark Plug Service In order to service the spark plug, you will need a spark plug wrench (commercially available). Recommended spark plugs: ZGR5A (NGK) J16CR-U (DENSO) To ensure proper engine operation, the spark plugs must be properly gapped and free of deposits. An incorrect spark plug can cause engine damage.
Check that the spark plug washers are in good condition, and thread the spark plugs in by hand to prevent cross-threading. After the spark plugs are seated, tighten with a spark plug wrench to compress the washer. If installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer.
Spark Arrester Maintenance If the generator has been running, the muffler will be very hot. Allow it to cool before proceeding. The spark arrester must be serviced every 100 hours to maintain its efficiency. Remove the special screw, and remove the spark arrester from the muffler.
Fuel Sediment Cup Cleaning The sediment cup prevents dirt or water that may be in the fuel tank from entering the carburetor. If the engine has not been run for a long time, the sediment cup should be cleaned. Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel.
Fuel Filter Check the fuel filter for water accumulation or sediment. FUEL FILTER If the fuel filter is found with excessive water accumulation or sediment, take the generator to your servicing dealer.
