CONTROLS ENGINE SWITCH To start and stop the engine. Switch position: OFF: To stop the engine. To start and run the engine. ENGINE SWITCH STARTER GRIP To start the engine, pull the starter grip lightly until you feel resistance, then pull briskly in the direction of the arrow as shown below. Do not allow the starter grip to snap back against the engine.
FUEL VALVE LEVER 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.
AC CIRCUIT BREAKER The AC circuit breaker will automatically switch OFF if there is a short circuit or an overload of the generator at the AC receptacle. If the AC circuit breaker is switched OFF automatically, check that the appliance is working properly and does not exceed the rated load capacity of the AC circuit before switching the AC circuit breaker ON again.
AC CIRCUIT PROTECTOR The AC circuit protector will automatically shut off the AC output power if there is a short circuit or an overload of the generator at the 20A receptacle. The yellow indicator inside the clear circuit protector button will pop out to show that the circuit protector has switched OFF.
Determine if the cause is a short circuit in a connected appliance or an overheated CycloConverter unit. Correct the problem and restart the engine. If the output indicator light (green) blinks again, consult your Honda generator dealer. The output indicator light (green) may blink at intervals of 2.5 seconds depending on connected appliance(s) to the AC receptacles.
DC RECEPTACLE The DC receptacle may ONLY be used for charging 12 volt automotive type batteries. DC CIRCUIT PROTECTOR The DC circuit protector automatically shuts off the DC battery charging circuit when the DC charging circuit is overloaded, when there is a problem with the battery, or when the connections between the battery and the generator are improper.
GROUND TERMINAL 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 to the intended use of the generator.
OIL ALERT SYSTEM The Oil Alert system is designed to prevent engine damage caused by an insufficient amount of oil in the crankcase. Before the oil level in the crankcase can fall below a safe limit, the Oil Alert indicator light comes on and the Oil Alert system will automatically stop the engine (the engine switch will remain in the ON position).
GROUND FAULT CIRCUIT INTERRUPTER (GFCI) RECEPTACLE The 20-ampere, 120-volt duplex receptacle that has TEST and RESET buttons is protected by a Ground Fault Circuit Interrupter (GFCI) against the hazards of ground fault currents. An example 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.
Unplug all appliances from the generator. Start the engine. Turn the circuit breaker ON. Press the TEST BUTTON The RESET BUTTON should extend with a click. If the RESET BUTTON does not extend, contact an authorized Honda generator dealer. TEST BUTTON RESET BUTTON...
The RESET BUTTON should be flush with the base. If the RESET BUTTON is not flush with the TEST BUTTON, contact an authorized Honda generator dealer. When the RESET BUTTON extends during operation: Unplug all appliances from the GFCI protected receptacle.
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.
AC APPLICATIONS Before connecting an appliance or power cord to the generator: Make sure that it is in good working order. Faulty appliances or power cords can create a potential for electrical shock. If an appliance begins to operate abnormally, becomes sluggish or stops suddenly, turn it off immediately.
AC OPERATION Start the engine and make sure the output indicator light (green) comes on (see page Switch ON the AC circuit breaker. Plug in the appliance. 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 engine switch immediately.
DC OPERATION The DC receptacle should ONLY be used for charging 12-volt automotive type batteries. The DC charging output is not regulated. Connecting the battery charging cable: Before connecting the battery charging cable (optional equipment) to a battery that is installed in a vehicle, disconnect the vehicle battery ground cable from the negative ( ) battery terminal.
If this happens, wait a few minutes before pushing in the circuit protector button to resume operation. If the circuit protector continues to go OFF, discontinue charging and see your authorized Honda generator dealer. Disconnecting the battery charging cable: Stop the engine.
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 ENGINE OIL SAE VISCOSITY GRADES Check the oil level BEFORE EACH USE with the generator on a level surface and the engine stopped. Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SJ or later (or equivalent).
REFUELING With the engine stopped, check the fuel level gauge. Refill the fuel tank if the fuel level is low. Refuel carefully to avoid spilling fuel. Do not fill above the upper limit. 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.
CALIFORNIA TYPE FUEL TANK CAP UPPER LIMIT (FUEL STRAINER SHOULDER) CHAIN EMPTY FULL FUEL LEVEL GAUGE After refueling, reinstall the fuel tank cap securely. 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.
STARTING THE ENGINE STARTING THE ENGINE For your safety, avoid starting or operating 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. Carbon monoxide gas is toxic.
STOPPING THE ENGINE STOPPING THE ENGINE In an emergency: To stop the engine in an emergency, turn the engine switch to the OFF position. In normal use: Turn the AC circuit breaker to the OFF position. Unplug appliances from the generator receptacles. Turn the engine switch to the OFF position.
Other service tasks that are more difficult, or require special tools, are best handled by professionals and are normally performed by a Honda technician or other qualified mechanic. The maintenance schedule applies to normal operating conditions.
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.
EPA and California emission regulations (models certified for sale in California). We recommend the use of genuine Honda 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.
AIR INDEX (Models certified for sale in California) An Air Index Information hang tag/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.
Replace paper element type only. Service more frequently when used in dusty areas. These items should be serviced by an authorized Honda dealer, unless the owner has the proper tools and is mechanically proficient. For commercial use, log hours of operation to determine proper maintenance intervals.
ENGINE OIL CHANGE Drain the oil while the engine is warm to assure rapid and complete draining. Place a suitable container below the engine to catch the oil, then remove the oil drain plug and sealing washer, remove the oil filler cap, and drain the oil.
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. Using gasoline or flammable solvent to clean the air filter can cause a fire or explosion.
Soak the foam air filter in clean engine oil and squeeze out the excess oil. The engine will smoke during initial startup if too much oil is left in the foam air filter. Reinstall the foam air filter to the air cleaner cover.
SPARK PLUG SERVICE In order to service the spark plug, you will need a spark plug wrench (commercially available). Recommended spark plugs: BPR6ES (NGK) W20EPR-U (DENSO) An incorrect spark plug can cause engine damage. To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.
Check that the spark plug sealing washer is in good condition, and thread the spark plug in by hand to prevent cross-threading. After the spark plug is 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.
FUEL SEDIMENT CUP CLEANING The sediment cup prevents dirt or water which 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. Turn the engine switch to the OFF position. Turn the fuel valve lever to the OFF position.
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 5 mm bolt, and remove the spark arrester from the muffler.
TRANSPORTING/STORAGE TRANSPORTING If the generator has been used, allow it 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 material. When transporting the generator, turn the engine switch and the fuel valve lever OFF, and keep the generator level to reduce the possibility of fuel leakage.
Change the engine oil (page 38). After removal from storage, drain the stored gasoline into a suitable container, and fill with fresh gasoline before starting. Use gasoline stabilizers that are formulated to extend storage life. Contact your authorized Honda generator dealer for stabilizer recommendations.
Storage Procedure Drain the fuel tank, the carburetor and the fuel sediment cup. Remove the carburetor drain bolt and sealing washer. Drain the gasoline from the carburetor into a suitable container. Install the sealing washer to the drain bolt and tighten the carburetor drain bolt.
