1. GENERATOR SAFETY Place the generator on a firm, level surface; avoid loose sand or snow. If the generator is tilted or overturned, fuel spillage may result. Also, if the generator is overturned or sinks into a soft surface, sand, dirt, or water may enter the generator. To prevent fire hazards and to provide adequate ventilation, keep the generator at least 1 meter (3 feet) away from buildings and other equipment during operation. Do not place flammable objects close to the generator.
Read these labels before you operate the generator. I [, EX4500S HONDA MOTOR CO., LTD. MADE D CAUTION 120/24OV VOLTAGE 60Hz FREQUENCY RATED OUTPUT 4.0kVA MAX.

3. PRE-OPERATION CHECK CAUTION: Check the generator on a level surface with the engine stopped. 1. ENGINE OIL CAUTION: Engine oil is a major factor affecting engine performance and service life. Non-detergent or 2-stroke engine oils are not recommended. Use Honda 4-stroke oil, or an equivalent high detergent, premium quality motor oil certified to meet or exceed U.S. automobile manufacturers’ requirements for Service Classification SG, SF/CC, CD.
2. FtiEL Check the fuel gauge and ,refill the tank if the fuel level is low. Your engine is designed to use any, gasoline that has a pump octane number ( R ‘2 M ) of 86 or higher, or that has a research octane number of 91 or higher. Gasoline pumps at service station normally display the pump octane number. We recommend that you use unleaded fuel because it produces fewer engine and spark plug deposits and extends the life of exhaust system components.
l l l l l Gasoline is extremely flammable and is explosive under certain conditions. Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where the engine is refueled or where gasoline is stored. Do not overfill the fuel tank (there should be no fuel in the filler neck). After refueling, make sure the tank cap is closed prdperly and secureiy. Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite.
3. Check the battery. The electrolyte level must be maintained between the UPPER and LOWER level marks. If the electrolyte level is near the LOWER mark, add distilled water. l l l . The battery gives off explosive gases; keep sparks, flames and cigarettes away. Provide adequate ventilation when charging or using batteries in an enclosed space. The battery contains sulfuric acid (electrolyte). Contact with skin or eyes may cause severe burns. Wear protective clothing and a face shield.
4. STARTING THE ENGINE CAUTION: When starting the generator after adding fuel for the first time, after long-term storage, or after running out of fuel, turn the engine switch to the “ON\’ position, then wait for 10 to 20 seconds before starting the engine. 1. Turn off the AC circuit breaker. \ @I @ , AC CIRCUIT BREAKER e ==z IEI 8 2. Make sure the auto-throttle for warm up.
3. Turn the engine switch to the START position and hold it there until the engine starts. NOTE: Do not use the electric starter for more than 5 seconds at a time. If the engine fails to start, release the switch and wait 10 seconds before operating the starter again. When the engine starts, allow the engine switch return to the ON position. ENGINE SWITCH 4. If auto-throttle will be used, turn the switch to “AUTO” has warmed up. after the engine NOTE: l AUTO is recommended to minimize fuel consumption.
5. GENERATOR USE l l To prevent electrical shock from faulty appliances, the generator should be grounded. Connect a length of heavy wire between the ground terminal and an external ground source. Connections for standby power to a building’s electrical system must be made by a qualified electrician and must comply with all applicable laws and electrical codes. Improper connections can allow electrical current from the generator to backfeed into the utility lines.
Auto-throttle System With the switch in the AUTO position, engine speed is automatically reduced to an idle when all loads are turned off or disconnected. When appliances are turned on or reconnected, the engine resumes the rated speed. At OFF, the auto-throttle system does not operate. NOTE: l AUTO is recommended to minimize fuel consumption when no load is applied. l The auto-throttle system will not respond to electrical loads of less than 1 ampere.
I I AC operation , 1. Start the engine. 2. Turn the voltage selector switch to either position as required. NOTE: With the voltage selector switch in the “12OV/24OV” position, you can use the 120V and 240V receptacles simultaneously. If you are not using the 240V receptacle, but you require more power from the 12OV twistlock receptacle, then turn the switch to the “120V” position. 3. Switch on the AC circuit breaker. 4. Plug in the appliance.
DC application The DC terminals teries only. may be used for charging 12 bolt automotive-type bat- 1. Connect both charging cables to the battery terminals and connect the positive (+I cable to the generator’s positive (+) DC terminal. 2. Start the generator. 3. Carefully connect the negative (-1 charging cable to the generator’s negative (-1 DC terminal. The battery gives off explosive gases; keep sparks, flames and cigarettes away.
CAUTION l Be careful to connect the charging cables to the correct battery and generator terminals (positive to’positive and negative to negative). If the charging cables are connected positive to negative, it may cause serious battery or generator damage. l Do not attempt to start an automobile engine with the generator still connected to the battery; this may damage the generator. NOTE: l The DC terminals may be used while the AC power is in use.
6: STOPPING THE ENGINE NOTE: To stop the engine in an emergency, OFF position. turn the engine switch to the In normal use: 1. Move the AC circuit breaker to the OFF position. Disconnect DC battery charging cables. AC CIRCUIT BREAKER 2. Turn the engine switch to the-OFF position.
7. MAINTENANCE Periodic maintenance and adjustment is necessary to keep the generator in good operating condition. Perform the service and inspection scheduled in the table on the following page. m Shut off the engine before performing any maintenance. If the engine must be run, make sure the area is well ventilated. Exhaust gas contains poisonous carbon monoxide. CAUTION: Use only genuine Honda parts or their equivalent for maintenance or repair.
Tool kit The tools supplikd with the generator will help you to perform the ownermaintenance procedures listed on page 20.
Changing oil Drain the oil while the engine is still warm to assure rapid and complete draining. 1. Open the front maintenance cover. 2. Remove the drain bolt and filler cap, and drain the oil. Retighten the bolt securely. 3. Refill with the recommended oil (see page 8) and check the level. 4. Close and latch the front maintenance cover. OIL CAPACITY: l.lP (1.
Air cleaner service A dirty air cleaner will restrict air flow to the carburetor. To prevent carburetor malfunction, service the air cleaner regularly (page 201.

CAUTION: Never wear will result. run the generator without 1. Open the rear maintenance cover. 2.
Spark plug service Recommended spark plug: BPRSES (NGK), Wl GEPR-U (ND) To ensure proper engine operation, the spark plug must be properly gapped and free of deposits. 1. 2; 3. 4. Open the rear maintenance cover. Remove the spark plug cap. Clean any dirt from around the spark plug base. Use the wrench supplied in the tool kit to remove the spark plug. , PLUG WRENCH 5. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped.
7. Check that the spark plug washer is in good condition, and thread the spark plug in by hand to prevent cross-threading. 8. After the spark plug is seated, tighten with a spark plug wrench to compress the washer. NOTE: If installing a new spark plug, tighten l/2 turn after the spark plug seats to compress the washer. If reinstalling a used spark plug, tighten l/8- l/4 turn after the spark plug seats. CAUTION: l The spark plug must be securely tightened.
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. 1. Open the left side maintenance cover. 2. Turn the engine switch to the OFF position. Remove the sediment cup : by turning it counterclockwise. 3. Clean the cup and O-ring in nonflammable or high flashpoint solvent. 4. Reinstall the O-ring and sediment cup. Tighten securely. 5.
