[. . . ] Refer to these serial numbers when ordering parts, and when making technical inquiry. SAFETY LABELS N These labels warn you of potential hazards that can cause serious injury. L I S Do not connect to a building's electrical system unless an isolation switch has been installed by a qualified electrician. Do not use a generator or electrical appliance in wet, conditions, such as rain or snow, or near a pool or sprinkler system, or when your hands are wet could result in electrocution. [. . . ] If any fuel is spilled, make sure the area is dry before starting the engine. We recommend unleaded gasoline because it produces fewer engine and spark plug deposits and extends exhaust system life. Occasionally you may hear light 'spark knock' or pinging' (metallic rapping noise) while operating under heavy loads. If spark knock or pinging occurs at a steady engine speed, under normal load, change brands of gasoline. G RECOIL STARTER To start the engine, pull the starter grip lightly until resistance is felt, then pull briskly. When the switch level move to ON position, fuel is allowed to flow from the fuel tank to the carburetor. 6-1B) N CHOKE LEVER (B) G The choke is used to provide an enriched fuel mixture when starting a cold eingine. 6-1C) I OIL ALERT SYSTEM S The oil alert system is designed to prevent engine damage caused by an insufficient amount of oil in the crankcase. H Before the oil level in the crankcase can fall below a safe limit, the oil alert system will automatically shut down the engine (the engine switch will remain in the ON position). Circuit Breaker The circuit breaker (A) will automatically switch OFF if there is a short circuit or a significant overload of the generator at the receptacle. If the circuit breaker is switched OFF automatically, check that the appliance is working properly and does not exceed the rated load capacity of the circuit before switching the circuit breaker ON again. 6-2A) Ground Terminal The generator ground terminal (B) is connected to the frame of the generater, the metal non-current carrying parts of the generator, and the ground terminals of each receptacle. 6-2B) Connections to a Building's Electrical System Connections for standby power to a building's electrical system must be made by a qualified electrician. The connection must isolate the generator power from utility power, and must comply with all applicable laws and electrical codes. Improper connections to a building's electrical system can allow electrical current from the generator to backfeed into the utility lines. Such backfeed may electrocute utility company workers or others who contact the lines during a power outage. Improper connections to a building's electrical system can allow electrical current from the utility company to backfeed into the generator. When utility power is restored, the generator may explode, burn, or cause fires in the building's electrical system. In some areas, generators are required by law to be registered with local utility companies. Generator Ground Circuits McCulloch portable generators have a system ground that connects generator frame components to the ground terminals in the AC output receptacles. Local regulations, codes or laws may require that the ground system be connected to the AC neutral wire. If the generator is tested by a receptacle tester, it will not show the same ground circuit condition as for a home receptacle. [. . . ] Gasoline is extremely flammable and is explosive under certain conditions Perform this task in a well ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area during this procedure. Remove the spark plug, and pour about a tablespoon of clean engine oil into the cylinder. Crank the engine several revolutions to distribute the oil, then reinstall the spark plug. [. . . ]
