5. GENERATOR USE w To prevent electrical shock from faulty appliances, the generator should be grounded. Connect a length of heavy wire between the ground terminal and the ground source. CAUTION: Limit operation requiring maximum power (EM3000: 3.0kVA. EM4000: 4.0 kVA) to 30 minutes. For continuous operation, do not exceed the ‘rated power of 2.8 WA (EM3000) and 3.8 kVA (EM4000). In either case, the total wattage of all appliances connected must be considered.
AC applications 1. Start the engine and make sure the pilot lamp comes on. If not, the filament may be burnt out. 2. Turn the voltage selector switch to either position as required. When the switch is turned to “120V ONLY” position, you can use only 120V AC. At “12OVf24OV” position, you can use both 120V and 240V sources. 3. Switch on the AC Circuit Breaker. 4. Plug in the appliance. CAUTION: Be sure that appliances do not exceed the rated load for more than 30 minutes, and never exceed the maximum load.
DC application The DC terminals may be used for charging 12 volt automotive-type batteries only. m Batteries produce explosive gases. Keep sparks, flames, and cigarettes away. To prevent the possibility of creating .a spark near the battery, connect charging cables first to the battery, then to the generator, and disconnect cables first at the generator. CAUTION: Do not attempt to start an automobile engine with the generator still connected to the battery. The generator may be damaged.
6. STOPPING THE ENGINE To stop the engine in an emergency, turn the engine switch OFF. In normal use: 1. Turn the AC circuit breakers OFF and or disconnect the charging leads at the DC terminals. AC CIRCUIT BREAKER 2. Turn the engine switch OFF.
3. Turn the fuel valve OFF.
7. MAINTENANCE The purpose of the maintenance schedule and adjustment generator in the best operating condition. Inspect or service as scheduled in the table on the next page. is to keep the m Shut off the engine before performing any maintenance. If the engine must be run, make sure the area is well ventilated. The exhaust contains poisonous carbon monoxide gas. CAUTION: Use only genuine HONDA parts or their equivalent.
Maintenance Schedule erform at every indi- Spark arrester Clean every 100 operating hours. NOTE (1) : Service more frequently when used in dusty areas. (2) : These items should be serviced by an authorized Honda dealer, unless the owner has the proper tools and is mechanically proficient. See the Honda Shop Manual.
Tool kit The tools supplied are necessary for performing simple adjustments and repairs. Always keep the kit with the generator. some periodic maintenance, Changing oil Drain the oil -while draining. the engine is still warm to assure rapid and complete 1. Remove the drain plug and filler cap, and drain the oil. Retighten the plug securely. 2. Refill with the-recommended oil (see page 4) and check the level.
Air cleaner service A dirty air cleaner will restrict air flow to the carburetor. To prevent carburetor malfunction, service the air cleaner regularly (page 20). Service more frequently when operating the generator in extremely dusty areas. m Never use gasoline or low flash point solvents for cleaning the air cleaner element. A fire or explosion could result. CAUTION: Never run the generator without the air cleaner. Rapid engine wear may result 1.
2. Wash the element in a non-flammable or high flash point solvent and dry it thoroughly. 3. Soak the element in clean engine oil and squeeze out the excess oil. 4. Reinstall the air cleaner element and the cover.
Fuel filter service The filter 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 filter should be cleaned. I. Turn the fuel valve OFF. Remove the filter cup. 2. Clean the cup thoroughly. 3. Reassemble. Do not damage the rubber gasket. m After installing the filter cup, check for fuel leaks and make sure the area is dry before starting the engine.
